Certified Addictions Registered Nurse (CARN) Exam — Questions and Answers

Question 1: A CARN discovers that a colleague is diverting opioid medications intended for addiction treatment patients. What is the nurse's primary ethical and legal obligation?

Maintain silence to protect patient privacy
Report only if the behavior continues after a warning
Confront the colleague privately and give them a chance to self-report
Document the behavior and report to the nursing supervisor and appropriate authorities (Correct answer)

Correct answer: Document the behavior and report to the nursing supervisor and appropriate authorities

Nurses have a legal and ethical duty to report suspected drug diversion to protect patient safety and comply with state reporting laws.

Question 2: When conducting a comprehensive biopsychosocial assessment for a patient with a suspected substance use disorder, which component is MOST crucial for the addictions nurse to explore to understand the context of the substance use?

A detailed list of all prescribed medications in the last five years.
The patient's highest level of education and employment history.
A chronological history of mental health symptoms and treatment, especially during periods of abstinence. (Correct answer)
The patient's family history of cardiovascular disease.

Correct answer: A chronological history of mental health symptoms and treatment, especially during periods of abstinence.

A key part of a biopsychosocial assessment for co-occurring disorders is understanding the relationship between mental health symptoms and substance use. Exploring the history of mental health symptoms, particularly during times when the patient was not using substances, helps differentiate between substance-induced symptoms and a primary mental health disorder, which is critical for accurate diagnosis and effective treatment planning.

Question 3: A patient is admitted for alcohol detoxification. During the initial nursing assessment, the patient reports 'feeling bugs crawling under my skin.' The nurse should document this as which of the following?

Paroxysmal sweats
Visual disturbances
Tactile disturbances (Correct answer)
Auditory hallucinations

Correct answer: Tactile disturbances

The sensation of bugs crawling on or under the skin is known as formication, which is a type of tactile disturbance or hallucination. On the CIWA-Ar scale, this symptom is specifically assessed under 'Tactile Disturbances.' Auditory disturbances involve hearing things, visual disturbances involve seeing things, and paroxysmal sweats refer to sudden episodes of sweating.

Question 4: How does emotional support contribute to addiction recovery?

It isolates the patient from their treatment team
It discourages patients from attending therapy sessions
It focuses only on managing withdrawal symptoms
It helps build resilience and maintain motivation throughout recovery (Correct answer)

Correct answer: It helps build resilience and maintain motivation throughout recovery

Emotional support is crucial in addiction recovery as it provides a sense of belonging, validation, and encouragement during a challenging process. This support helps patients build resilience to cope with setbacks and maintain motivation throughout their recovery journey. It fosters a positive outlook, which is essential for sustained engagement in treatment and achieving long-term sobriety.

Question 5: A nurse working with a patient with co-occurring borderline personality disorder and alcohol use disorder should prioritize which treatment approach?

Pharmacotherapy alone without psychotherapy
Inpatient psychiatric hospitalization until remission
Strict 12-step program attendance without individual therapy
Dialectical behavior therapy combined with motivational enhancement (Correct answer)

Correct answer: Dialectical behavior therapy combined with motivational enhancement

Dialectical behavior therapy combined with motivational enhancement therapy is well-supported for co-occurring BPD and alcohol use disorder, addressing both emotion dysregulation and substance use.

Question 6: When a patient threatens to harm a specific, identifiable third party, a nurse's legal duty under Tarasoff principles requires:

Consulting an ethics committee before taking any action
Maintaining confidentiality and documenting the threat in the chart only
Warning the potential victim and notifying appropriate authorities (Correct answer)
Increasing the patient's medication to reduce risk

Correct answer: Warning the potential victim and notifying appropriate authorities

Tarasoff establishes a duty to warn identifiable potential victims when a credible threat of harm exists, overriding typical confidentiality.

Question 7: Varenicline (Chantix) reduces nicotine craving through which pharmacological mechanism?

Full agonism at nicotinic acetylcholine receptors, continuously stimulating reward
Antagonism of mu-opioid receptors that mediate nicotine reward
Partial agonism at α4β2 nicotinic receptors, providing modest dopamine release while blocking nicotine (Correct answer)
Inhibition of dopamine reuptake in the mesolimbic pathway

Correct answer: Partial agonism at α4β2 nicotinic receptors, providing modest dopamine release while blocking nicotine

Varenicline is a partial agonist at α4β2 nicotinic receptors, providing enough dopamine stimulation to reduce craving while competitively blocking nicotine's full effect.

Question 8: A patient on buprenorphine/naloxone reports that injecting the medication produces little to no euphoria. Which pharmacological property of naloxone best explains this?

Naloxone has a longer half-life than buprenorphine
Naloxone induces CYP3A4 metabolism of buprenorphine
Naloxone causes histamine release that blunts reward
Naloxone blocks opioid receptors when administered parenterally (Correct answer)

Correct answer: Naloxone blocks opioid receptors when administered parenterally

Naloxone has poor sublingual bioavailability but becomes active when injected, blocking opioid receptors and precipitating withdrawal, deterring misuse.

Question 9: Which education content should the nurse prioritize when a patient with stimulant use disorder is being discharged?

Recognition of stimulant-induced psychosis signs and the importance of outpatient follow-up (Correct answer)
Prescription medication options available for cocaine use disorder
Instructions for tapering stimulants over two weeks
How to manage stimulant cravings with antihistamines

Correct answer: Recognition of stimulant-induced psychosis signs and the importance of outpatient follow-up

Stimulant withdrawal can precipitate psychosis, making recognition of symptoms and timely outpatient follow-up critical discharge education priorities.

Question 10: Which screening tool is specifically validated for identifying unhealthy alcohol use in primary care settings?

AUDIT-C (Correct answer)
DAST-10
PHQ-9
CAGE-AID

Correct answer: AUDIT-C

The AUDIT-C is a validated 3-item screen derived from the full AUDIT, specifically designed for rapid detection of unhealthy alcohol use in primary care.

Question 11: A nurse counsels a patient with alcohol use disorder who has achieved 6 months of sobriety. What is accurate about ongoing relapse risk?

Relapse risk returns to near zero after 6 months of sustained sobriety
Relapse risk is highest in the first year and remains elevated for several years (Correct answer)
Relapse risk only exists when patients are exposed to environmental triggers
Completing a 12-Step program eliminates significant relapse risk

Correct answer: Relapse risk is highest in the first year and remains elevated for several years

Relapse risk is highest during the first year of recovery and remains significantly elevated for several years, reflecting the chronic nature of addiction.

Question 12: A nurse on an inpatient detoxification unit has a strong suspicion that a colleague is diverting opioid medications intended for patients. The nurse observes the colleague frequently taking breaks after medication administration and notes several documentation discrepancies. What is the nurse's primary ethical and professional responsibility in this situation?

Confront the colleague directly and give them a chance to explain before taking further action.
Discuss the concerns with other trusted coworkers to see if they have noticed similar behaviors.
Gather more definitive proof over the next several shifts to build a stronger case.
Report the suspicions immediately to the nursing supervisor or through the facility's established reporting channels. (Correct answer)

Correct answer: Report the suspicions immediately to the nursing supervisor or through the facility's established reporting channels.

According to the American Nurses Association (ANA) Code of Ethics, the nurse's primary commitment is to the patient's safety. When impaired practice is suspected, especially involving drug diversion which endangers patients, the nurse has an obligation to report these concerns to the appropriate authority (e.g., a manager or supervisor) to protect patients from harm. Waiting to gather more evidence or confronting the colleague directly could place patients at further risk.

Question 13: A patient with opioid use disorder who is breastfeeding asks if they can continue buprenorphine. The nurse's education should convey that:

Buprenorphine is absolutely contraindicated during breastfeeding
Breastfeeding is only safe if the buprenorphine dose is below 8 mg/day
Buprenorphine transfers minimally into breast milk and breastfeeding is generally supported while on stable MOUD (Correct answer)
The patient must choose between breastfeeding and MOUD with no middle option

Correct answer: Buprenorphine transfers minimally into breast milk and breastfeeding is generally supported while on stable MOUD

Current evidence supports breastfeeding in stable MOUD patients because buprenorphine transfers minimally into breast milk, and the benefits of breastfeeding outweigh the risks.

Question 14: When using the SAMHSA No Wrong Door approach for individuals with co-occurring disorders, the primary goal is to:

Require patients to self-identify their primary diagnosis for routing
Allow any system entry point to connect individuals to comprehensive services (Correct answer)
Ensure patients are triaged to the most restrictive level of care
Separate mental health and addiction services for clearer accountability

Correct answer: Allow any system entry point to connect individuals to comprehensive services

The No Wrong Door approach ensures that regardless of which system a person enters — mental health, substance use, or primary care — they are connected to comprehensive, coordinated services for all their needs.

Question 15: A patient in recovery identifies 'people, places, and things' associated with past drug use as things to avoid. This concept is best described as:

Cognitive distortions about use
Environmental cue conditioning (Correct answer)
Negative reinforcement patterns
Emotional dysregulation triggers

Correct answer: Environmental cue conditioning

Environmental cues become conditioned stimuli through repeated pairing with substance use, capable of triggering cravings even years into recovery via classical conditioning.

Question 16: What is the primary role of a nurse implementing Twelve-Step Facilitation (TSF) therapy?

To act as the client's temporary sponsor and guide them through the 12 steps.
To lead 12-step meetings within the clinical setting as a substitute for community meetings.
To mandate that the client attend a specific number of AA or NA meetings per week.
To actively encourage participation in community-based 12-step groups and explain the core principles. (Correct answer)

Correct answer: To actively encourage participation in community-based 12-step groups and explain the core principles.

Twelve-Step Facilitation (TSF) is a structured clinical strategy where the therapist's role is to facilitate a client's active engagement with 12-step mutual-help organizations like AA or NA. This involves education on 12-step principles, exploring and overcoming barriers to attendance, and encouraging participation, but the nurse does not act as a sponsor or lead the meetings themselves.

Question 17: Which pharmacological property of kratom makes it relevant to opioid use disorder treatment discussions?

Kratom enhances endogenous endorphin release without receptor binding
Kratom selectively antagonizes kappa-opioid receptors, reducing dysphoria
Kratom blocks dopamine reuptake transporters, producing stimulant effects only
Kratom's active alkaloids act as partial agonists at mu-opioid receptors (Correct answer)

Correct answer: Kratom's active alkaloids act as partial agonists at mu-opioid receptors

Kratom's active alkaloids (mitragynine, 7-hydroxymitragynine) are partial mu-opioid receptor agonists, producing opioid-like effects and carrying dependence and withdrawal risk.

Question 18: What is a major concern when using pharmacological interventions in addiction treatment?

There is no concern with pharmacological treatments
It leads to immediate and permanent sobriety
The potential for misuse or dependence on the medication (Correct answer)
It completely cures addiction immediately

Correct answer: The potential for misuse or dependence on the medication

A significant concern with pharmacological interventions in addiction treatment is the potential for patients to misuse the prescribed medication or develop a new dependence. This risk necessitates careful monitoring by healthcare professionals, appropriate prescribing practices, and thorough patient education. The goal is to support recovery without inadvertently creating new substance use issues.

Question 19: A patient with alcohol use disorder states, "I know I should cut back for my health, but a few beers with my friends is the only way I can relax after a tough week." Which response by the CARN best demonstrates the principle of developing discrepancy in Motivational Interviewing?

"Why don't you just invite your friends to do something that doesn't involve drinking?"
"It's good that you recognize the need to cut back. Let's set a goal for you to only have two beers next time."
"It sounds like on one hand, you value your health, and on the other hand, relaxing with friends is very important to you. How do you see these two things fitting together?" (Correct answer)
"You need to find a healthier way to relax or you'll face serious health consequences."

Correct answer: "It sounds like on one hand, you value your health, and on the other hand, relaxing with friends is very important to you. How do you see these two things fitting together?"

This response is a complex reflection that highlights the patient's internal conflict (discrepancy) between their stated values (health) and their current behavior (drinking to relax), without judgment. This technique helps the patient explore their own ambivalence and motivations for change, which is a core tenet of Motivational Interviewing.

Question 20: A patient with schizophrenia and cannabis use disorder reports that marijuana helps reduce their auditory hallucinations. The nurse's BEST response is:

Explain that cannabis may temporarily relieve symptoms but worsens psychosis long-term (Correct answer)
Immediately discharge the patient from treatment for noncompliance
Increase antipsychotic medication to compete with cannabis effects
Validate their experience and allow continued use since it is helping

Correct answer: Explain that cannabis may temporarily relieve symptoms but worsens psychosis long-term

The nurse should use psychoeducation to explain that while cannabis may provide short-term relief, it is associated with worsened psychosis, earlier onset, and poorer long-term outcomes in schizophrenia.

Question 21: What is a common symptom of alcohol addiction that may be assessed?

Improved memory
Increased motivation
Excessive energy
Cravings, tolerance, and withdrawal symptoms (Correct answer)

Correct answer: Cravings, tolerance, and withdrawal symptoms

Cravings, increased tolerance to alcohol's effects, and the experience of withdrawal symptoms when alcohol use is reduced or stopped are classic indicators of alcohol addiction. These symptoms reflect the physiological and psychological dependence that develops with chronic alcohol misuse, making them key assessment points. Recognizing these signs helps in accurate diagnosis and intervention.

Question 22: What is the role of motivational interviewing in addiction assessment?

To ignore patient concerns about addiction
To encourage patients to maintain their current habits
To motivate patients to engage in treatment and address their addiction issues (Correct answer)
To provide immediate therapy

Correct answer: To motivate patients to engage in treatment and address their addiction issues

Motivational interviewing is a patient-centered counseling approach designed to help individuals explore and resolve their ambivalence about change. In addiction assessment, it's used to enhance a patient's intrinsic motivation to engage in treatment and commit to addressing their substance use, fostering readiness for change rather than imposing it. This collaborative approach empowers patients in their recovery journey.

Question 23: Why is buprenorphine used in opioid addiction treatment?

To alleviate withdrawal symptoms and reduce cravings for opioids (Correct answer)
To completely eliminate opioid cravings permanently
To replace opioid addiction with other substances
To cause opioid overdoses

Correct answer: To alleviate withdrawal symptoms and reduce cravings for opioids

Buprenorphine is a partial opioid agonist used in Medication-Assisted Treatment (MAT) for opioid addiction. It works by binding to opioid receptors, which helps to alleviate withdrawal symptoms and significantly reduce cravings for opioids. Unlike full agonists, buprenorphine has a 'ceiling effect,' meaning its opioid effects level off at a certain dose, reducing the risk of misuse and overdose, making it a safer option for many patients.

Question 24: A patient's family member asks how they can best support their loved one in recovery. Which response by the nurse is most therapeutic?

Take control of all financial and social decisions for the patient
Monitor all communications and limit the patient's independence
Attend Al-Anon or similar family support groups and maintain healthy boundaries (Correct answer)
Remove all stressors from the patient's life to prevent relapse

Correct answer: Attend Al-Anon or similar family support groups and maintain healthy boundaries

Family support groups like Al-Anon help family members develop healthy boundaries while providing peer support for their own wellbeing.

Question 25: Which ethical principle is MOST at stake when a nurse provides inaccurate information about the risks of medication-assisted treatment to steer a patient toward a preferred abstinence-only program?

Autonomy
Veracity (Correct answer)
Justice
Fidelity

Correct answer: Veracity

Veracity (truth-telling) is violated when a nurse provides inaccurate or incomplete information that influences a patient's treatment decision.

Question 26: Why is it essential to monitor a patient’s progress during treatment?

To prevent the patient from participating in future therapy sessions
To track progress, adjust the plan, and ensure successful recovery (Correct answer)
To make the patient feel inadequate if they don’t meet expectations
To ensure the patient is not following the treatment plan

Correct answer: To track progress, adjust the plan, and ensure successful recovery

Monitoring a patient's progress during addiction treatment is essential to assess the effectiveness of interventions and identify areas needing adjustment. This ongoing evaluation allows the treatment team to tailor the plan to the patient's evolving needs. By tracking progress, the team can ensure strategies remain relevant and supportive, maximizing the chances of successful, long-term recovery.

Question 27: What role does family involvement play in addiction treatment planning?

It isolates the patient from their family dynamics
It eliminates the need for therapy sessions
It encourages a supportive environment for recovery and strengthens the patient’s social network (Correct answer)
It prevents the patient from focusing on their own recovery

Correct answer: It encourages a supportive environment for recovery and strengthens the patient’s social network

Family involvement plays a significant role in addiction treatment planning by creating a supportive and understanding environment essential for recovery. Addiction often impacts the entire family system, and involving family members can help heal relationships, improve communication, and educate them on how to best support their loved one. This strengthened social network provides crucial encouragement and accountability, reducing isolation and enhancing the patient's chances of sustained sobriety.

Question 28: Varenicline (Chantix) aids smoking cessation primarily through which mechanism?

Full agonism at nicotinic acetylcholine receptors
Partial agonism at alpha-4 beta-2 nicotinic receptors, reducing cravings and blocking nicotine reward (Correct answer)
Inhibition of dopamine reuptake in the nucleus accumbens
Antagonism of NMDA glutamate receptors

Correct answer: Partial agonism at alpha-4 beta-2 nicotinic receptors, reducing cravings and blocking nicotine reward

Varenicline acts as a partial agonist at alpha-4 beta-2 nicotinic receptors, providing low-level stimulation to reduce cravings while blocking nicotine's full rewarding effect.

Question 29: A nurse is using motivational interviewing during a patient education session. Which nurse statement best reflects the MI principle of 'affirmation'?

'You mentioned you've been sober for two weeks — that takes real strength.' (Correct answer)
'Most patients in your situation end up relapsing within the first month.'
'Have you considered that your family is suffering because of your choices?'
'You really need to stop using or things will get much worse.'

Correct answer: 'You mentioned you've been sober for two weeks — that takes real strength.'

Affirmation in motivational interviewing involves recognizing and acknowledging the patient's strengths and efforts to build rapport and self-efficacy.

Question 30: A patient with generalized anxiety disorder and benzodiazepine use disorder is being treated with a taper protocol. Which adjunct medication would MOST appropriately address anxiety during and after the taper?

Selective serotonin reuptake inhibitor (SSRI) (Correct answer)
Another benzodiazepine at lower dose
Propranolol for cardiac symptoms only
Hydroxyzine only at bedtime

Correct answer: Selective serotonin reuptake inhibitor (SSRI)

SSRIs are first-line pharmacotherapy for generalized anxiety disorder and are non-addictive, making them appropriate adjuncts during benzodiazepine tapering in patients with co-occurring benzodiazepine use disorder.

Question 31: Which of the following is a key diagnostic tool in addiction assessment?

Personality assessments
Physical exams
DSM-5 diagnostic criteria for substance use disorders (Correct answer)
Blood tests

Correct answer: DSM-5 diagnostic criteria for substance use disorders

The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition) provides standardized diagnostic criteria for substance use disorders. This tool is essential for clinicians to accurately diagnose the presence and severity of an addiction, ensuring consistent and evidence-based assessment practices in the field. It offers a common language and framework for understanding and classifying these complex conditions.

Question 32: Which psychosocial intervention is specifically designed to enhance a patient's internal motivation to change addictive behaviors by exploring ambivalence?

12-Step Facilitation Therapy
Motivational Interviewing (MI) (Correct answer)
Dialectical Behavior Therapy (DBT)
Cognitive Behavioral Therapy (CBT)

Correct answer: Motivational Interviewing (MI)

Motivational Interviewing is a patient-centered, directive counseling style designed to elicit and strengthen motivation for change by resolving ambivalence.

Question 33: A patient offers a CARN an expensive watch as a discharge gift, stating the nurse was instrumental in their recovery. Which action best upholds professional and ethical boundaries?

Politely decline the gift, explaining that the professional relationship and the patient's success are the true rewards. (Correct answer)
Accept the watch but immediately turn it over to the unit manager to be used for the patient care fund.
Suggest the patient mail the gift to the nurse's home to avoid a scene at the facility.
Accept the gift to avoid hurting the patient's feelings during a vulnerable time.

Correct answer: Politely decline the gift, explaining that the professional relationship and the patient's success are the true rewards.

Professional nursing organizations like the ANA and NCSBN have clear guidelines on maintaining professional boundaries, which includes the acceptance of gifts. Accepting a gift of significant value can blur the lines of the therapeutic relationship, create a sense of obligation, and be seen as exploitative. The most ethical response is to graciously and politely decline, reinforcing the professional nature of the relationship and reaffirming the intrinsic rewards of nursing.

Question 34: A nurse is caring for a patient with schizophrenia and alcohol use disorder. Which treatment approach is most evidence-based for this population?

Refer to separate specialized programs for each disorder
Treat the psychiatric disorder first, then the addiction
Integrated dual diagnosis treatment addressing both simultaneously (Correct answer)
Treat the addiction first, then the psychiatric disorder

Correct answer: Integrated dual diagnosis treatment addressing both simultaneously

Integrated dual diagnosis treatment that addresses both co-occurring disorders simultaneously is the most evidence-based approach for individuals with serious mental illness and substance use disorders.

Question 35: When educating a pregnant patient about substance use disorder, which resource referral is most essential?

A specialized perinatal addiction treatment program (Correct answer)
A weight-loss program to improve nutrition
A standard prenatal yoga class only
An over-the-counter supplement guide

Correct answer: A specialized perinatal addiction treatment program

Perinatal addiction treatment programs provide coordinated care that addresses both substance use and obstetric needs simultaneously.

Question 36: Why is patient education important in addiction recovery?

To help the patient avoid all types of therapy
To encourage patients to abandon their treatment plan
To empower the patient with knowledge to manage their recovery (Correct answer)
To prevent the patient from making decisions about their care

Correct answer: To empower the patient with knowledge to manage their recovery

Patient education is vital in addiction recovery because it empowers individuals with a deeper understanding of addiction as a chronic disease and their specific treatment plan. This knowledge helps them identify personal triggers, understand relapse warning signs, and make informed decisions about their health. Empowered patients are more likely to actively participate in managing their own long-term recovery journey.

Question 37: Which assessment finding distinguishes cannabis use disorder from recreational cannabis use under DSM-5 criteria?

Presence of at least 2 of 11 diagnostic criteria causing significant impairment (Correct answer)
Positive urine toxicology screen for THC metabolites
Patient self-identifies as dependent on cannabis
Frequency of use exceeds once per week

Correct answer: Presence of at least 2 of 11 diagnostic criteria causing significant impairment

DSM-5 requires at least 2 of 11 specific criteria resulting in clinically significant impairment or distress to diagnose cannabis use disorder.

Question 38: A patient is being assessed for opioid withdrawal using the Clinical Opiate Withdrawal Scale (COWS). The nurse observes a resting heart rate of 115 bpm, beads of sweat on the patient's forehead, and the patient is unable to sit still for more than a few seconds. These objective findings would contribute to which components of the COWS score?

Runny Nose/Tearing, Gooseflesh Skin, and Tremor
Bone/Joint Aches, Pupil Size, and Anxiety/Irritability
Resting Pulse Rate, Sweating, and Restlessness (Correct answer)
GI Upset, Tremor, and Yawning

Correct answer: Resting Pulse Rate, Sweating, and Restlessness

The COWS is an 11-item scale that includes objective measures. A heart rate of 115 bpm would be scored under Resting Pulse Rate, visible beads of sweat fall under the Sweating category, and the inability to sit still is rated under Restlessness. The other options list different components of the COWS scale that do not match the described symptoms.

Question 39: A nurse is using the SBIRT model to address substance use with a patient in a primary care setting. After the initial screening indicates risky alcohol consumption, what is the immediate next step according to this model?

Administer a medication for alcohol craving.
Provide a referral to a specialty treatment center.
Complete a full psychiatric evaluation.
Engage the patient in a brief intervention. (Correct answer)

Correct answer: Engage the patient in a brief intervention.

SBIRT stands for Screening, Brief Intervention, and Referral to Treatment. Following a positive screening, the model dictates that the healthcare provider should engage the patient in a brief, non-judgmental conversation known as a Brief Intervention. This conversation aims to provide feedback, enhance motivation for change, and collaboratively set goals. Referral to treatment is reserved for individuals identified as needing a higher level of care.

Question 40: Which nursing intervention is most important when administering methadone in an opioid treatment program (OTP)?

Allow the patient to take the dose home after the first visit
Administer the dose intramuscularly to ensure absorption
Observe the patient swallow the dose to confirm ingestion (Correct answer)
Hold the dose if the patient appears intoxicated without further assessment

Correct answer: Observe the patient swallow the dose to confirm ingestion

Direct observation of methadone ingestion (DOT) is required at OTPs to prevent diversion and confirm therapeutic dosing.

Question 41: Dialectical Behavior Therapy (DBT) is an evidence-based practice frequently used for individuals with complex co-occurring disorders. It is particularly effective for patients who primarily exhibit which cluster of symptoms?

Obsessive thoughts and compulsive, ritualistic behaviors.
Grandiose thinking, racing thoughts, and a decreased need for sleep.
Emotional dysregulation, impulsivity, and self-harm behaviors. (Correct answer)
Social isolation, anhedonia, and low motivation.

Correct answer: Emotional dysregulation, impulsivity, and self-harm behaviors.

DBT was originally developed to treat Borderline Personality Disorder and focuses on teaching skills to manage intense emotions, reduce self-destructive behaviors, and improve interpersonal relationships. Its core components—mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness—directly target the emotional dysregulation and impulsivity common in complex dual-diagnosis presentations.

Question 42: When educating a patient about harm reduction strategies for injection drug use, the nurse should include information about:

Avoiding all contact with other people who use drugs
Restricting fluids to reduce vein damage
How to obtain prescription opioids legally to replace street drugs
Using clean syringes, never sharing equipment, and wound care (Correct answer)

Correct answer: Using clean syringes, never sharing equipment, and wound care

Harm reduction education includes syringe exchange programs, sterile equipment use, and wound care to reduce infection and disease transmission risk.

Question 43: What is a key indicator of opioid addiction during assessment?

Using opioids in larger amounts and experiencing withdrawal symptoms (Correct answer)
Lack of interest in social activities
Increased appetite
Frequent urination

Correct answer: Using opioids in larger amounts and experiencing withdrawal symptoms

Key indicators of opioid addiction include a pattern of using opioids in larger amounts or over a longer period than intended, along with the development of withdrawal symptoms when use is discontinued or reduced. These symptoms, such as muscle aches, nausea, and intense cravings, signify physical dependence and are crucial for diagnosis. Identifying these patterns guides appropriate treatment strategies.

Question 44: A 28-year-old patient presents with rhinorrhea, lacrimation, goosebumps, and a COWS score of 18. Which level of opioid withdrawal does this represent?

Moderate withdrawal
Mild withdrawal
Moderately severe withdrawal
Severe withdrawal (Correct answer)

Correct answer: Severe withdrawal

A COWS score of 13 or higher indicates severe opioid withdrawal requiring prompt clinical intervention.

Question 45: Cannabis produces its psychoactive effects primarily by acting on which receptor system?

5-HT2A serotonin receptors in the cortex
Alpha-2 adrenergic receptors in the locus coeruleus
CB1 cannabinoid receptors in the CNS (Correct answer)
TRPV1 vanilloid receptors in the periphery

Correct answer: CB1 cannabinoid receptors in the CNS

THC acts as a partial agonist at CB1 receptors in the CNS, producing psychoactive effects including euphoria, altered perception, and impaired memory.

Question 46: A patient 3 months into recovery states, 'I can go to parties where everyone is drinking — I have strong willpower now.' The nurse recognizes this as:

An appropriate goal for someone in late-stage recovery
A healthy sign of growing self-confidence in recovery
Evidence of well-developed coping skills
A cognitive distortion that significantly increases relapse risk (Correct answer)

Correct answer: A cognitive distortion that significantly increases relapse risk

Overconfidence and underestimating high-risk situations ('I'm cured') is a cognitive distortion common in early recovery that substantially elevates relapse risk.

Question 47: A patient prescribed buprenorphine/naloxone reports feeling 'sick' after taking the first dose. Which assessment finding best explains precipitated withdrawal?

The dose was too low to bind opioid receptors
The patient took the dose sublingually rather than swallowed
The patient was still in full opioid intoxication when buprenorphine was given (Correct answer)
The naloxone component caused sedation

Correct answer: The patient was still in full opioid intoxication when buprenorphine was given

Precipitated withdrawal occurs when buprenorphine displaces full agonist opioids from receptors before sufficient withdrawal has occurred, causing abrupt withdrawal symptoms.

Question 48: Neuroimaging studies of individuals with addiction commonly show reduced glucose metabolism and blood flow in which brain region?

Prefrontal cortex (Correct answer)
Medulla oblongata
Occipital cortex
Primary motor cortex

Correct answer: Prefrontal cortex

PET and fMRI studies consistently show hypofrontality (reduced prefrontal cortex activity) in addiction, correlating with impaired inhibitory control and decision-making.

Question 49: Which concept describes the phenomenon where increasing doses of a substance are required to achieve the same effect?

Kindling
Sensitization
Tolerance (Correct answer)
Cross-tolerance

Correct answer: Tolerance

Tolerance is the neuroadaptive process requiring increased amounts of a substance to achieve the desired effect.

Question 50: In Prochaska's Transtheoretical Model, which stage is characterized by the patient making specific plans to change behavior within the next 30 days?

Maintenance
Action
Preparation (Correct answer)
Contemplation

Correct answer: Preparation

The Preparation stage involves intending to take action soon (within 30 days) and beginning to make specific plans, such as calling a treatment center.

Question 51: A patient with alcohol use disorder undergoes assessment and scores a 7 on the CIWA-Ar. Which clinical response is most appropriate?

Increase monitoring frequency and consider PRN symptom-triggered medication (Correct answer)
Transfer to the ICU for intensive monitoring
Initiate intravenous benzodiazepine infusion immediately
Discharge with follow-up in 48 hours

Correct answer: Increase monitoring frequency and consider PRN symptom-triggered medication

A CIWA-Ar score of 7 indicates mild withdrawal; increased monitoring and symptom-triggered (PRN) benzodiazepines are appropriate at this level.

Question 52: Why is it important to assess a patient’s substance use history before starting pharmacological treatment?

To delay the start of treatment until the patient feels better
To determine if the patient is eligible for free treatment
To force the patient to stop using all substances immediately
To personalize treatment and avoid potential drug interactions (Correct answer)

Correct answer: To personalize treatment and avoid potential drug interactions

Assessing a patient's substance use history before starting pharmacological treatment is crucial for several reasons. It allows healthcare providers to personalize the treatment plan by selecting the most appropriate medication and dosage based on the specific substances used, duration, and severity of dependence. More importantly, it helps identify potential drug interactions, contraindications, and co-occurring medical conditions, ensuring patient safety and maximizing treatment efficacy.

Question 53: Which type of coping skill education is most evidence-based for patients with co-occurring PTSD and substance use disorder?

Integrated trauma-informed approaches such as Seeking Safety (Correct answer)
Teaching patients to suppress trauma-related thoughts to avoid distress
Focusing solely on 12-step attendance without addressing PTSD
Encouraging patients to address trauma only after 5 years of sobriety

Correct answer: Integrated trauma-informed approaches such as Seeking Safety

Seeking Safety is an evidence-based, integrated intervention that simultaneously addresses PTSD and substance use without requiring trauma processing.

Question 54: Methadone's utility in opioid use disorder is partly due to its long half-life. What is the approximate half-life of methadone?

24–36 hours (Correct answer)
8–12 hours
2–4 hours
5–7 days

Correct answer: 24–36 hours

Methadone's half-life of 24–36 hours (sometimes up to 59 hours) allows once-daily dosing and prevents withdrawal, supporting medication adherence.

Question 55: Which statement about buprenorphine's ceiling effect is clinically most significant?

At higher doses, increasing buprenorphine does not proportionally increase respiratory depression, reducing overdose risk (Correct answer)
The ceiling effect prevents buprenorphine from being effective in high-tolerance patients
Buprenorphine's ceiling effect means it always requires combination with naloxone
Buprenorphine cannot produce analgesia above certain doses

Correct answer: At higher doses, increasing buprenorphine does not proportionally increase respiratory depression, reducing overdose risk

As a partial agonist, buprenorphine's respiratory depression effect plateaus at higher doses, making overdose from buprenorphine alone far less likely than with full opioid agonists.

Question 56: A patient on methadone maintenance therapy reports QTc prolongation on ECG. What is the most appropriate nursing action?

Administer a beta-blocker
Notify the prescriber and monitor for arrhythmias (Correct answer)
Increase the methadone dose gradually
Discontinue methadone immediately

Correct answer: Notify the prescriber and monitor for arrhythmias

Methadone can prolong the QTc interval, increasing risk of torsades de pointes, so the prescriber must be notified and cardiac monitoring initiated.

Question 57: A patient with opioid use disorder discloses they have been drinking heavily while on buprenorphine. The nurse's priority ethical and clinical obligation is to:

Immediately discontinue buprenorphine to prevent harm
Document the disclosure and assess safety risk without punitive response (Correct answer)
Report the patient to the prescribing physician and discontinue treatment
Notify family members about the concurrent alcohol use

Correct answer: Document the disclosure and assess safety risk without punitive response

The nurse should document, assess safety, and respond therapeutically rather than punitively, as non-judgmental care is foundational in addiction nursing.

Question 58: A nurse is caring for a client in acute opioid withdrawal who is experiencing intense anxiety, dysphoria, and irritability. These symptoms are primarily driven by the activation of stress systems in which brain region?

Prefrontal Cortex
Hippocampus
Basal Ganglia
Extended Amygdala (Correct answer)

Correct answer: Extended Amygdala

The withdrawal/negative affect stage of addiction is strongly linked to the extended amygdala. During withdrawal, there is a decrease in reward system function and an activation of brain stress neurotransmitters, like corticotropin-releasing factor (CRF) and norepinephrine, within the extended amygdala, leading to negative emotional states such as anxiety, dysphoria, and irritability.

Question 59: A nurse assesses a patient in early opioid withdrawal who also has a history of PTSD. Which symptom would be MOST concerning and warrant immediate intervention?

Mild nausea and diaphoresis
Mild anxiety and irritability
Yawning and lacrimation
Suicidal ideation with a plan (Correct answer)

Correct answer: Suicidal ideation with a plan

Suicidal ideation with a plan is an immediate safety concern requiring urgent psychiatric intervention, as individuals with co-occurring PTSD and opioid withdrawal are at elevated suicide risk.

Question 60: A patient with opioid use disorder is court-ordered to treatment but refuses medication-assisted treatment on religious grounds. The ethical principle most relevant to honoring this refusal is:

Autonomy (Correct answer)
Beneficence
Nonmaleficence
Justice

Correct answer: Autonomy

Autonomy supports a patient's right to refuse treatment, including specific modalities, even when court-ordered for the treatment program itself.

Question 61: When assessing a patient for opioid use disorder, which physical finding is most consistent with chronic opioid use?

Skin flushing and diaphoresis
Track marks and venous sclerosis at injection sites (Correct answer)
Hypertension and tachycardia at rest
Pupillary dilation

Correct answer: Track marks and venous sclerosis at injection sites

Track marks and venous sclerosis are classic physical signs of repeated intravenous opioid use.

Question 62: The DSM-5 diagnoses substance use disorder on a severity continuum. Which combination of criteria count correctly defines 'severe' SUD?

2-3 criteria
6 or more criteria (Correct answer)
1 criterion plus hospitalization
4-5 criteria

Correct answer: 6 or more criteria

DSM-5 classifies SUD as mild (2-3 criteria), moderate (4-5 criteria), and severe (6 or more criteria).

Question 63: Which term describes the simultaneous presence of a substance use disorder and at least one psychiatric disorder?

Polypharmacy
Comorbid medical condition
Substance-induced disorder
Dual diagnosis (Correct answer)

Correct answer: Dual diagnosis

Dual diagnosis (also called co-occurring disorders) refers to the concurrent presence of a substance use disorder and a psychiatric disorder.

Question 64: When using the SBIRT model, what does the 'BI' component involve for a patient who screens positive for risky substance use?

Biological inventory of withdrawal symptoms
Baseline intake for inpatient detoxification
Brief intervention to raise awareness and motivate change (Correct answer)
Blood and immunological testing

Correct answer: Brief intervention to raise awareness and motivate change

Brief Intervention (BI) in SBIRT involves a short, motivational conversation to increase awareness of substance use risks and encourage behavior change.

Question 65: Which of the following scenarios best illustrates the DSM-5 diagnostic criterion of 'risky use' for a substance use disorder?

A patient reports needing to drink more alcohol than before to feel the same effects.
A patient misses several important family events because they are recovering from the effects of binge drinking.
A patient has tried to stop using cocaine multiple times but has been unsuccessful.
A patient continues to drive their commercial truck after smoking cannabis, despite company policy and safety warnings. (Correct answer)

Correct answer: A patient continues to drive their commercial truck after smoking cannabis, despite company policy and safety warnings.

The 'risky use' criterion in the DSM-5 refers to recurrent substance use in situations where it is physically hazardous. Driving a vehicle while under the influence of cannabis is a clear example of this. Needing more of a substance is tolerance, unsuccessful attempts to quit relate to impaired control, and missing events due to use falls under social impairment.

Question 66: Which instrument is the gold-standard structured interview for diagnosing substance use disorders according to DSM-5 criteria?

CAGE questionnaire
SCID-5 (Structured Clinical Interview for DSM-5) (Correct answer)
MAST (Michigan Alcoholism Screening Test)
AUDIT

Correct answer: SCID-5 (Structured Clinical Interview for DSM-5)

The SCID-5 is the gold-standard structured diagnostic interview used to assess and confirm DSM-5 substance use disorder diagnoses.

Question 67: When using motivational interviewing, a nurse reflects back a patient's ambivalence by saying 'So on one hand you want to quit drinking, but on the other, alcohol helps you cope with stress.' This technique is called:

Amplified reflection
Reframing
Double-sided reflection (Correct answer)
Simple reflection

Correct answer: Double-sided reflection

A double-sided reflection explicitly acknowledges both sides of ambivalence, helping the patient hear their own conflicting statements.

Question 68: Which patient statement indicates successful understanding of naloxone overdose response education?

'I'll call 911, give the naloxone, and stay with the person until help arrives.' (Correct answer)
'Naloxone will work immediately and keep the person safe for at least 24 hours.'
'I should wait to see if the person wakes up on their own before giving naloxone.'
'I only need one dose of naloxone regardless of how much opioid was taken.'

Correct answer: 'I'll call 911, give the naloxone, and stay with the person until help arrives.'

Correct overdose response includes calling 911, administering naloxone, and staying with the person because naloxone's effects are shorter than most opioids.

Question 69: A patient in alcohol withdrawal scores 15 on the CIWA-Ar. Which medication is the first-line pharmacological intervention?

Disulfiram
Lorazepam (Correct answer)
Haloperidol
Naltrexone

Correct answer: Lorazepam

Benzodiazepines such as lorazepam are first-line agents for managing moderate-to-severe alcohol withdrawal due to their cross-tolerance with alcohol at GABA receptors.

Question 70: A patient with a history of chronic alcohol use disorder reports that they no longer feel the same pleasure from activities they once enjoyed, a condition known as anhedonia. As a CARN, you understand this is primarily due to neuroadaptive changes in which key neurotransmitter system?

Dopamine (Correct answer)
Glutamate
Serotonin
GABA

Correct answer: Dopamine

Chronic alcohol use leads to a blunting of the mesolimbic dopamine system, often called the brain's reward pathway. This neuroadaptation results in a decreased sensitivity to both the substance and natural rewards, leading to anhedonia. While other neurotransmitters are affected, the dysregulation of dopamine is central to the loss of pleasure and motivational deficits seen in addiction.

Question 71: Which brain region is most associated with drug-cue conditioned responses and craving triggered by environmental stimuli?

Cerebellum
Basal ganglia
Amygdala (Correct answer)
Thalamus

Correct answer: Amygdala

The amygdala encodes emotional memories associated with drug use and mediates conditioned responses to drug-related cues that trigger craving.

Question 72: What is the first step in addiction assessment?

Creating a treatment plan
Providing immediate therapy
Gathering detailed patient history and information (Correct answer)
Administering a diagnostic test

Correct answer: Gathering detailed patient history and information

The first step in addiction assessment is to collect comprehensive information about the patient's substance use, medical history, mental health, and social context. This detailed history provides a foundational understanding of their unique situation, which is critical for accurate diagnosis and developing an effective, individualized treatment plan. Without this initial data, subsequent steps would lack essential context.

Question 73: Which relapse prevention model identifies high-risk situations, coping responses, and self-efficacy as its core components?

Gorski's CENAPS Model
Marlatt's Cognitive-Behavioral Model (Correct answer)
Prochaska's Transtheoretical Model
Miller's Motivational Enhancement Model

Correct answer: Marlatt's Cognitive-Behavioral Model

Marlatt's Cognitive-Behavioral Model identifies high-risk situations, the individual's coping response, and self-efficacy as the key determinants of whether relapse occurs.

Question 74: A patient who has maintained abstinence from alcohol for several months is prescribed acamprosate (Campral). The nurse should explain that the primary goal of this medication is to:

Reduce acute withdrawal symptoms such as tremors and seizures.
Treat underlying depression that often co-occurs with alcohol use disorder.
Restore the balance between GABA and glutamate neurotransmission to reduce cravings. (Correct answer)
Induce a negative physical reaction if alcohol is consumed.

Correct answer: Restore the balance between GABA and glutamate neurotransmission to reduce cravings.

Acamprosate is thought to work by modulating and normalizing alcohol-disrupted brain activity, specifically by restoring the balance between the excitatory neurotransmitter glutamate and the inhibitory neurotransmitter GABA. This action helps to reduce the protracted withdrawal symptoms like craving and anxiety that can lead to relapse.

Question 75: A patient presents with severe anxiety and benzodiazepine dependence. After stabilization, which non-addictive anxiolytic medication would be most appropriate for long-term anxiety management?

Clonazepam
Alprazolam
Lorazepam
Buspirone (Correct answer)

Correct answer: Buspirone

Buspirone is a non-addictive anxiolytic that does not carry abuse potential, making it appropriate for long-term anxiety management in patients with benzodiazepine use disorder.

Question 76: A nurse in an integrated treatment program notices a patient with co-occurring disorders is rotating between individual therapy, group therapy, and case management in the same week. This model is BEST described as:

Parallel treatment
Sequential treatment
Integrated treatment (Correct answer)
Step-down treatment

Correct answer: Integrated treatment

Integrated treatment involves a unified team addressing both substance use and mental health within the same program simultaneously, which is distinct from sequential or parallel models.

Question 77: According to the American Society of Addiction Medicine (ASAM) criteria, which of the following patient profiles would most likely require placement in a Level 3.7, medically monitored intensive inpatient treatment?

A patient who is motivated for treatment, has a stable home environment, and is at low risk for withdrawal.
A patient experiencing moderate withdrawal symptoms that can be managed with ambulatory detoxification and has a supportive family.
A patient with a severe, unstable co-occurring medical condition and a high risk of life-threatening withdrawal that requires 24-hour nursing care. (Correct answer)
A patient who has completed residential treatment and needs ongoing support to prevent relapse.

Correct answer: A patient with a severe, unstable co-occurring medical condition and a high risk of life-threatening withdrawal that requires 24-hour nursing care.

ASAM Level 3.7 is designed for patients with significant medical and/or psychiatric instability who are at high risk for severe withdrawal. This level provides 24-hour nursing care and physician availability to manage complex needs that cannot be safely handled in a less intensive setting.

Question 78: What is the significance of relapse prevention education in addiction treatment?

To prevent the patient from leaving their home environment
To ignore any future challenges
To help the patient recognize triggers and avoid relapse situations (Correct answer)
To stop therapy and discontinue recovery efforts

Correct answer: To help the patient recognize triggers and avoid relapse situations

Relapse prevention education is critical in addiction treatment because it equips patients with the knowledge and skills to identify their personal triggers and understand warning signs. This education helps them develop effective coping strategies to navigate high-risk situations. By proactively preparing for challenges, patients can significantly reduce the likelihood of returning to substance use.

Question 79: Which principle of adult learning (andragogy) should most guide patient education design for adults in addiction treatment?

Adults learn best through passive reception of expert-delivered content
Adult learning is most effective when structured around grades and formal assessments
Adults require more repetition than younger learners and need simplified content
Adult learners are self-directed and motivated by education that is immediately relevant to their lives (Correct answer)

Correct answer: Adult learners are self-directed and motivated by education that is immediately relevant to their lives

Andragogy emphasizes that adults are self-directed learners who engage most effectively with education that is immediately relevant and practical to their real-world situations.

Question 80: A patient in opioid withdrawal reports severe muscle cramping, diarrhea, and yawning. Using the COWS scale, which domain captures the yawning symptom?

Autonomic signs (Correct answer)
Restlessness
GI upset
Sweating

Correct answer: Autonomic signs

Yawning is scored under autonomic signs on the Clinical Opiate Withdrawal Scale (COWS).

Question 81: Which level of care on the ASAM continuum involves medically managed intensive inpatient services (Level 4)?

Intensive outpatient programs meeting 3 days per week
Residential treatment without 24-hour medical supervision
Hospital-based programs with 24-hour physician availability (Correct answer)
Medically monitored inpatient detoxification only

Correct answer: Hospital-based programs with 24-hour physician availability

ASAM Level 4 is medically managed intensive inpatient treatment, requiring 24-hour physician-directed care in a hospital or equivalent setting.

Question 82: A CARN has a credible reason to believe a colleague is diverting opioid medications intended for patients. According to the ANA Code of Ethics, what is the nurse's primary responsibility?

Report the observations immediately to the nursing supervisor in accordance with facility policy. (Correct answer)
Confront the colleague directly and threaten to report them if the behavior continues.
Wait to gather definitive proof before taking any action to avoid a false accusation.
Anonymously report the colleague to the state board of nursing without informing the employer.

Correct answer: Report the observations immediately to the nursing supervisor in accordance with facility policy.

The ANA Code of Ethics states that the nurse's primary commitment is to the patient. Provision 3.5 emphasizes the duty to protect patients from harm by acting on impaired practice. While some guidelines suggest approaching the colleague, the overriding ethical and legal duty is to ensure patient safety by reporting the issue through the proper chain of command, which is typically the nursing supervisor. This allows the organization to take immediate steps to protect patients and address the impaired practice.

Question 83: A patient on buprenorphine/naloxone (Suboxone) attempts to inject the crushed film. What is the expected outcome?

Severe hepatotoxicity from naloxone injection
Intensified opioid effect due to intravenous buprenorphine
Precipitated withdrawal from naloxone's systemic effects when injected (Correct answer)
No effect because buprenorphine is insoluble

Correct answer: Precipitated withdrawal from naloxone's systemic effects when injected

When injected, naloxone achieves systemic bioavailability and antagonizes opioid receptors, precipitating acute withdrawal — the intended abuse-deterrent mechanism.

Question 84: A patient on methadone maintenance is prescribed erythromycin for an infection. The nurse's priority concern is:

QTc interval prolongation increasing risk of torsades de pointes (Correct answer)
Serotonin syndrome from combined serotonergic activity
Increased methadone sedation from CNS synergy
Reduced methadone efficacy due to enzyme induction

Correct answer: QTc interval prolongation increasing risk of torsades de pointes

Both methadone and erythromycin can prolong the QTc interval, and their combination significantly increases risk of life-threatening torsades de pointes.

Question 85: A patient with severe alcohol use disorder develops delirium tremens 72 hours after last drink. Which pharmacological intervention is the first-line treatment?

Clonidine to manage autonomic hyperactivity
Phenobarbital as first-line because it is safer than benzodiazepines
Haloperidol to control agitation and hallucinations
High-dose benzodiazepines titrated to symptom control using CIWA-Ar (Correct answer)

Correct answer: High-dose benzodiazepines titrated to symptom control using CIWA-Ar

Benzodiazepines are first-line for delirium tremens; they enhance GABA-A activity to suppress CNS hyperexcitability and are titrated using symptom-triggered protocols like CIWA-Ar.

Question 86: The concept of 'opponent process theory' as applied to addiction explains:

The mechanism by which naloxone reverses opioid overdose
How classical conditioning pairs neutral stimuli with drug effects
Why initial drug pleasure is followed by an opposing aversive state that grows with repeated use (Correct answer)
Why two drugs can have additive effects when used together

Correct answer: Why initial drug pleasure is followed by an opposing aversive state that grows with repeated use

Opponent process theory posits that the initial pleasurable 'A-process' is opposed by an aversive 'B-process' that strengthens over time, driving tolerance and withdrawal-motivated use.

Question 87: A CARN is performing a substance use screening using the CAGE-AID questionnaire. The 'A' in the acronym CAGE-AID prompts the nurse to ask which of the following questions?

"Have you ever felt bad or Guilty about your drinking or drug use?"
"Have you ever felt you needed to cut down on your drinking or drug use?"
"Have people Annoyed you by criticizing your drinking or drug use?" (Correct answer)
"Have you ever had a drink or used drugs first thing in the morning (Eye-opener)?"

Correct answer: "Have people Annoyed you by criticizing your drinking or drug use?"

The CAGE-AID is an acronym for Cut down, Annoyed, Guilty, and Eye-opener. The 'A' specifically refers to whether other people have been annoyed by the individual's substance use, which can be an indicator of social problems related to their use.

Question 88: What is one common mental health disorder that co-occurs with addiction?

Bipolar disorder
Obsessive-compulsive disorder
Depression and anxiety (Correct answer)
Schizophrenia

Correct answer: Depression and anxiety

Depression and anxiety are among the most common mental health disorders that frequently co-occur with substance use disorders, a phenomenon known as dual diagnosis. Individuals often use substances to self-medicate these underlying conditions, making it essential to assess and treat both issues concurrently for successful recovery. Addressing both aspects leads to more comprehensive and lasting healing.

Question 89: Nicotine replacement therapy (NRT) reduces withdrawal symptoms primarily by:

Increasing dopamine release beyond what tobacco provides
Blocking nicotine receptors to prevent tobacco from binding
Inhibiting acetylcholinesterase to enhance cholinergic tone
Providing controlled nicotine delivery to reduce withdrawal without behavioral reinforcement of smoking (Correct answer)

Correct answer: Providing controlled nicotine delivery to reduce withdrawal without behavioral reinforcement of smoking

NRT delivers nicotine in controlled doses to reduce withdrawal symptoms and cravings while eliminating tobacco combustion products and the behavioral ritual of smoking.

Question 90: During a comprehensive addiction assessment, which domain is assessed by asking about a patient's employment, legal history, and living situation?

Family genogram
Withdrawal severity
Biopsychosocial functioning (Correct answer)
Medical history

Correct answer: Biopsychosocial functioning

Employment, legal history, and living situation are components of the biopsychosocial assessment that evaluates functioning across multiple life domains.

Question 91: MDMA (ecstasy) primarily causes serotonin syndrome risk when combined with which class of medications?

Beta-blockers
Antipsychotics
Monoamine oxidase inhibitors (MAOIs) (Correct answer)
Calcium channel blockers

Correct answer: Monoamine oxidase inhibitors (MAOIs)

MDMA causes massive serotonin release; MAOIs prevent serotonin breakdown, leading to life-threatening serotonin syndrome when combined.

Question 92: Naltrexone is contraindicated in a patient who:

Has a history of alcohol use disorder
Is enrolled in a smoking cessation program
Is currently taking opioids for pain management (Correct answer)
Has mild renal impairment

Correct answer: Is currently taking opioids for pain management

Naltrexone blocks opioid receptors and will precipitate acute withdrawal in patients physically dependent on opioids.

Question 93: A patient with opioid use disorder is being considered for medication-assisted treatment. Which medication requires a DEA waiver (X-waiver) for outpatient prescribing by physicians?

Methadone for OUD treatment
Buprenorphine/naloxone (Correct answer)
Naltrexone extended-release injection
Naltrexone oral formulation

Correct answer: Buprenorphine/naloxone

Buprenorphine for OUD treatment in outpatient settings historically required a DEA X-waiver, though regulations have evolved; methadone for OUD must be dispensed through opioid treatment programs.

Question 94: Which of the following correctly describes the pharmacokinetic advantage of methadone in treating opioid use disorder?

Long half-life (24–36 hours) enables once-daily dosing and prevents withdrawal between doses (Correct answer)
Rapid onset makes it effective for acute overdose reversal
Low protein binding reduces drug interaction risk
Short half-life allows flexible dosing schedules

Correct answer: Long half-life (24–36 hours) enables once-daily dosing and prevents withdrawal between doses

Methadone's long half-life of 24–36 hours allows once-daily dosing, maintains stable blood levels, and prevents the peaks and troughs that drive craving.

Question 95: A patient with alcohol use disorder is being discharged. Which education topic is highest priority to reduce risk of life-threatening complications?

How to manage mild insomnia with herbal teas
Benefits of joining a gym for physical health
Dietary restrictions for a low-sodium diet
Signs and symptoms of alcohol withdrawal including seizures and delirium tremens (Correct answer)

Correct answer: Signs and symptoms of alcohol withdrawal including seizures and delirium tremens

Alcohol withdrawal can progress to seizures and delirium tremens, which are potentially fatal, making this the highest priority discharge education topic.

Question 96: Which receptor subtype is primarily responsible for the euphoric effects of opioids?

Delta (δ)
Mu (μ) (Correct answer)
Sigma (σ)
Kappa (κ)

Correct answer: Mu (μ)

Mu (μ) opioid receptors mediate euphoria, analgesia, and respiratory depression, making them the primary target for opioid misuse.

Question 97: A nurse is implementing a contingency management (CM) program for a client with stimulant use disorder. Which of the following nursing actions best aligns with the principles of this intervention?

Teaching the client cognitive-behavioral techniques to identify and reframe negative thought patterns.
Exploring the client's internal motivation for change through collaborative conversation.
Administering a prescribed medication to reduce cravings and withdrawal symptoms.
Providing a gift card for each verified stimulant-free urine drug screen. (Correct answer)

Correct answer: Providing a gift card for each verified stimulant-free urine drug screen.

Contingency management is a behavioral therapy that provides tangible rewards to reinforce positive behaviors, such as abstinence. Providing a gift card for a negative drug screen is a direct application of this principle, using positive reinforcement to encourage the desired behavior. The other options describe different, though also valuable, interventions: motivational interviewing, medication-assisted treatment, and cognitive-behavioral therapy.

Question 98: Which of the following is a relapse WARNING SIGN rather than an external trigger?

Seeing friends who continue to use substances
Passing a bar where the patient used to drink
Smelling alcohol at a family gathering
Increased social isolation and withdrawal from support (Correct answer)

Correct answer: Increased social isolation and withdrawal from support

Warning signs like social isolation and attitude changes are internal behavioral/emotional shifts that precede relapse, distinguishable from external environmental triggers.

Question 99: A patient with known bipolar I disorder and alcohol use disorder presents to the emergency department in a manic state, exhibiting agitation and paranoia. What is the CARN's initial priority action?

Obtain a detailed history of the patient's substance use.
Ensure the safety of the patient and the clinical environment. (Correct answer)
Initiate a protocol for alcohol withdrawal.
Administer a long-acting antipsychotic as ordered.

Correct answer: Ensure the safety of the patient and the clinical environment.

According to the principles of patient safety and crisis management, the immediate priority in a situation with agitation and paranoia is to ensure the safety of the patient, staff, and others in the environment. De-escalation techniques and creating a safe milieu precede all other interventions, including detailed assessments or non-emergent medication administration.

Question 100: When comparing the prognosis of individuals with a single substance use disorder to those with a co-occurring SUD and a mental health disorder, the presence of the dual diagnosis is most strongly associated with which outcome?

A faster response to initial pharmacological treatment.
A higher rate of successfully completing treatment programs.
Lower overall lifetime healthcare costs.
Increased rates of relapse, hospitalization, and homelessness. (Correct answer)

Correct answer: Increased rates of relapse, hospitalization, and homelessness.

Individuals with co-occurring disorders face significant challenges, as the symptoms of each disorder can exacerbate the other. This interaction leads to more severe symptoms, poorer treatment outcomes, higher rates of relapse for both conditions, and increased utilization of acute services like hospitalization compared to those with a single disorder.

Question 101: What role does goal setting play in addiction treatment planning?

To avoid setting any benchmarks for success
To provide clear, measurable objectives that guide treatment and track progress (Correct answer)
To increase the number of sessions needed
To create unrealistic expectations for the patient

Correct answer: To provide clear, measurable objectives that guide treatment and track progress

Goal setting is fundamental in addiction treatment planning as it provides a clear roadmap for both the patient and the treatment team. By establishing specific, measurable, achievable, relevant, and time-bound (SMART) objectives, patients gain direction and a sense of purpose in their recovery journey. These goals allow for consistent tracking of progress, celebrate achievements, and guide necessary adjustments to the treatment plan, fostering accountability and motivation.

Question 102: Which of the following is a key principle of Assertive Community Treatment (ACT) that makes it particularly effective for individuals with co-occurring serious mental illness and substance use disorders?

Office-based appointments during standard business hours
Mandatory medication compliance as a condition of services
High staff-to-patient ratios with outreach in the community (Correct answer)
Group-only treatment format to reduce costs

Correct answer: High staff-to-patient ratios with outreach in the community

ACT uses high staff-to-patient ratios and meets patients in their natural environment, making it highly effective for engaging individuals with serious mental illness and co-occurring substance use disorders who struggle with traditional clinic-based care.

Question 103: Why is it important to assess both psychological and physical aspects of addiction?

To focus only on physical detoxification
To identify all aspects of the addiction and create a comprehensive treatment plan (Correct answer)
To concentrate solely on the psychological symptoms
To ignore underlying mental health issues

Correct answer: To identify all aspects of the addiction and create a comprehensive treatment plan

Addiction is a multifaceted disease affecting both the mind and body. Assessing both psychological and physical aspects allows healthcare professionals to understand the full scope of the individual's addiction, including co-occurring mental health issues and physical health complications. This holistic view is vital for developing an integrated and effective treatment plan that addresses all needs, leading to better recovery outcomes.

Question 104: Which illicit opioid is frequently involved in overdose deaths due to its extremely high potency relative to morphine?

Codeine
Buprenorphine
Illicitly manufactured fentanyl (IMF) (Correct answer)
Tramadol

Correct answer: Illicitly manufactured fentanyl (IMF)

Illicitly manufactured fentanyl is approximately 100 times more potent than morphine, making even microgram dosing errors fatal.

Question 105: Which neurotransmitter is primarily responsible for the reinforcing effects of addictive substances in the mesolimbic pathway?

GABA
Serotonin
Norepinephrine
Dopamine (Correct answer)

Correct answer: Dopamine

Dopamine release in the nucleus accumbens via the mesolimbic pathway mediates the rewarding and reinforcing effects of addictive substances.

Question 106: In a patient with co-occurring opioid use disorder and chronic pain, which pharmacological consideration is most important when prescribing buprenorphine?

Full opioid agonists must be prescribed alongside buprenorphine for adequate pain management
Buprenorphine must be discontinued before any surgical procedure due to analgesia blockade
Buprenorphine is contraindicated in chronic pain as it will worsen hyperalgesia
Buprenorphine provides partial analgesia and can treat both conditions; dose splitting (TID/QID) may optimize pain control (Correct answer)

Correct answer: Buprenorphine provides partial analgesia and can treat both conditions; dose splitting (TID/QID) may optimize pain control

Buprenorphine has analgesic properties at standard doses, and dividing the daily dose into multiple administrations can improve pain coverage while maintaining OUD treatment.

Question 107: A client is admitted for methamphetamine withdrawal. The nurse's plan of care should prioritize monitoring for which of the following conditions during the first few days of withdrawal?

Severe gastrointestinal bleeding.
Life-threatening seizures and delirium tremens.
Intense cravings and profound depression. (Correct answer)
Hypertensive crisis and tachycardia.

Correct answer: Intense cravings and profound depression.

While physical symptoms occur, methamphetamine withdrawal is primarily characterized by severe psychological symptoms. During the initial 'crash' phase (the first 1-2 days), individuals experience extreme fatigue, but this is followed by a period of intense cravings, anhedonia (inability to feel pleasure), and severe depression, which can include suicidal ideation. While vital signs can fluctuate, a hypertensive crisis is not typical, and seizures are less common than with alcohol or benzodiazepine withdrawal.

Question 108: Why is aftercare an essential component of treatment planning?

To avoid having the patient return for any future sessions
To continue treatment until complete recovery is achieved
To help patients maintain progress, manage challenges, and prevent relapse (Correct answer)
To focus only on detoxification

Correct answer: To help patients maintain progress, manage challenges, and prevent relapse

Aftercare is an essential component of addiction treatment planning because recovery is a lifelong process, not just the completion of an initial program. It provides ongoing support and resources to help patients navigate the challenges of daily life, cope with triggers, and prevent relapse after leaving intensive treatment. Effective aftercare plans, which may include support groups, therapy, or sober living arrangements, significantly improve long-term sobriety rates and help individuals maintain their progress.

Question 109: A client with a severe alcohol use disorder is denied a spot on a liver transplant list, with a committee member privately stating it's a 'waste of an organ.' Which of the following actions by the addictions nurse best exemplifies the role of a patient advocate?

Helping the client file a formal grievance with the hospital's patient advocacy department and transplant ethics committee. (Correct answer)
Telling the client to seek a second opinion at a different hospital.
Documenting the biased statement in the client's chart.
Advising the family to hire a lawyer to sue the hospital for discrimination.

Correct answer: Helping the client file a formal grievance with the hospital's patient advocacy department and transplant ethics committee.

Patient advocacy involves actively working to protect a patient's rights and ensuring they receive equitable, unbiased care. Substance use disorders are recognized medical conditions, and denying care based on stigma is unethical. The most effective advocacy action is to use the established systems to challenge the decision by helping the client navigate the formal grievance process, which empowers the patient and directly addresses the potential discrimination within the system.

Question 110: Which action best exemplifies the CARN maintaining professional boundaries with a patient in long-term recovery?

Providing personal phone number for after-hours support
Accepting a small gift as a token of the patient's gratitude
Declining a social media connection request from a current patient (Correct answer)
Attending the patient's community recovery celebration with supervisor approval

Correct answer: Declining a social media connection request from a current patient

Declining social media connections from current patients maintains appropriate professional boundaries and protects therapeutic relationships.

Question 111: A nurse is preparing to administer naloxone to a patient with suspected opioid overdose who is also opioid-dependent. The anticipated risk after naloxone administration is:

Seizures from sudden GABA receptor activation
Respiratory stimulation causing hyperventilation
Precipitated withdrawal with agitation, vomiting, and potential violence (Correct answer)
Prolonged sedation from naloxone's CNS depressant effects

Correct answer: Precipitated withdrawal with agitation, vomiting, and potential violence

Naloxone rapidly reverses opioid effects in dependent patients, precipitating acute withdrawal characterized by agitation, vomiting, diaphoresis, and combativeness.

Question 112: Phosphatidylethanol (PEth) is a biomarker that can detect alcohol use for up to how long after consumption?

24-48 hours
Up to 3 months
Up to 3-4 weeks (Correct answer)
5-7 days

Correct answer: Up to 3-4 weeks

PEth, a direct alcohol biomarker, can be detected in blood for up to 3-4 weeks after heavy alcohol consumption.

Question 113: PCP (phencyclidine) produces its dissociative and psychotic effects primarily through which mechanism?

Antagonism of NMDA glutamate receptors (Correct answer)
Stimulation of kappa-opioid receptors
Blockade of serotonin 5-HT3 receptors
Agonism at GABA-A receptors

Correct answer: Antagonism of NMDA glutamate receptors

PCP blocks NMDA glutamate receptors (a dissociative mechanism), producing hallucinations, agitation, analgesia, and psychosis-like symptoms.

Question 114: A CARN is asked by law enforcement to confirm whether a specific individual is enrolled in the clinic's treatment program. The appropriate response is to:

Provide enrollment information since law enforcement has authority
Confirm enrollment but provide no clinical details
Consult with the medical director before responding
Neither confirm nor deny enrollment without a court order or patient consent (Correct answer)

Correct answer: Neither confirm nor deny enrollment without a court order or patient consent

Under 42 CFR Part 2, the existence of a patient's treatment record is itself protected and cannot be confirmed without consent or court order.

Question 115: When providing education to a patient beginning buprenorphine therapy, the nurse should emphasize that sublingual films should be:

Crushed and mixed with juice
Chewed and then swallowed
Held under the tongue until fully dissolved (Correct answer)
Swallowed whole with water for faster absorption

Correct answer: Held under the tongue until fully dissolved

Buprenorphine sublingual films must be held under the tongue until fully dissolved to ensure proper absorption through the sublingual mucosa.

Question 116: Which of the following is a core principle of Trauma-Informed Care (TIC) when establishing a therapeutic environment for clients with substance use disorders?

Maintaining a strict, hierarchical relationship between staff and clients to provide structure.
Focusing treatment exclusively on the substance use disorder before addressing any trauma.
Emphasizing physical and psychological safety in all interactions and environments. (Correct answer)
Requiring clients to provide a detailed account of their trauma history during intake.

Correct answer: Emphasizing physical and psychological safety in all interactions and environments.

According to the Substance Abuse and Mental Health Services Administration (SAMHSA), a primary and foundational principle of a trauma-informed approach is ensuring the physical and psychological safety of clients and staff. This creates an environment where healing is possible and seeks to actively avoid re-traumatization.

Question 117: Which benzodiazepine is preferred for alcohol withdrawal management in patients with severe liver disease?

Chlordiazepoxide
Diazepam
Alprazolam
Lorazepam (Correct answer)

Correct answer: Lorazepam

Lorazepam (along with oxazepam and temazepam) undergoes direct glucuronidation and is preferred in hepatic impairment because it avoids extensive liver metabolism.

Question 118: When educating an older adult patient about alcohol use disorder, the nurse should particularly address:

That naltrexone is contraindicated in all patients over 70
That alcohol use disorder is rare in adults over 65 and likely misdiagnosed
That brief interventions are not effective for older adults
Age-related pharmacokinetic changes that increase alcohol's effects and drug interaction risks (Correct answer)

Correct answer: Age-related pharmacokinetic changes that increase alcohol's effects and drug interaction risks

Aging causes reduced hepatic metabolism and total body water, increasing blood alcohol concentration and drug interaction risk at lower consumption levels.

Question 119: During alcohol withdrawal, lorazepam is often preferred over diazepam in patients with severe liver disease. Why?

Lorazepam has a longer half-life requiring less frequent dosing
Lorazepam has a lower risk of respiratory depression
Lorazepam has no active metabolites and requires cytochrome P450 enzymes
Lorazepam undergoes direct glucuronidation and does not rely on oxidative hepatic metabolism (Correct answer)

Correct answer: Lorazepam undergoes direct glucuronidation and does not rely on oxidative hepatic metabolism

Lorazepam is metabolized via direct glucuronidation, bypassing CYP450 enzymes compromised in liver disease, preventing toxic accumulation.

Question 120: A patient on methadone maintenance develops a prolonged QTc interval on ECG. Which factor most directly explains methadone's cardiac risk?

Methadone induces electrolyte wasting through renal mechanisms
Methadone activates mu-opioid receptors in the sinoatrial node
Methadone stimulates sympathetic outflow, increasing heart rate and QTc
Methadone blocks cardiac hERG potassium channels, prolonging cardiac repolarization (Correct answer)

Correct answer: Methadone blocks cardiac hERG potassium channels, prolonging cardiac repolarization

Methadone blocks hERG (IKr) potassium channels responsible for cardiac repolarization, prolonging the QTc interval and increasing torsades de pointes risk.

Question 121: Why is it important to tailor a treatment plan to each individual?

Because every patient needs the same treatment
Because it simplifies the treatment process for all patients
Because it eliminates the need for follow-up sessions
Because a personalized plan increases engagement and effectiveness (Correct answer)

Correct answer: Because a personalized plan increases engagement and effectiveness

Tailoring a treatment plan to each individual is vital because addiction manifests differently in everyone, influenced by unique biological, psychological, and social factors. A personalized approach ensures that interventions directly address the patient's specific challenges, preferences, and goals, which significantly increases their engagement and motivation. This individualized care leads to more effective outcomes and a higher likelihood of sustained recovery.

Question 122: A patient who has been sober from alcohol for six months is exposed to the sight and smell of their favorite bar, triggering intense cravings. This phenomenon of cue-induced craving is strongly mediated by learned associations within which two brain structures?

Thalamus and Hypothalamus
Nucleus Accumbens and Amygdala (Correct answer)
Medulla and Reticular Formation
Cerebellum and Pons

Correct answer: Nucleus Accumbens and Amygdala

The Nucleus Accumbens is involved in motivation and reward, while the Amygdala is critical for processing emotional memories and forming associations between environmental cues and rewards. Repeated pairing of drug use with specific cues (people, places, things) strengthens these connections, allowing the cues themselves to activate the reward pathway and trigger powerful cravings.

Question 123: A patient expresses shame about their addiction during an education session. The most therapeutic nursing response is to:

Agree that making better choices sooner would have been ideal
Remind the patient of their responsibilities to their family
Redirect the conversation immediately to medication adherence
Validate their feelings while emphasizing that addiction is a chronic brain disease, not a moral failure (Correct answer)

Correct answer: Validate their feelings while emphasizing that addiction is a chronic brain disease, not a moral failure

Validating feelings while framing addiction as a chronic brain disease reduces shame and stigma, which are significant barriers to treatment engagement.

Question 124: A patient scoring 15 on the CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol) should be managed with which intervention?

Outpatient monitoring only
Pharmacological treatment with benzodiazepines (Correct answer)
Immediate discharge with written instructions
Non-pharmacological comfort measures alone

Correct answer: Pharmacological treatment with benzodiazepines

A CIWA-Ar score of 15 or higher indicates severe alcohol withdrawal requiring pharmacological intervention, typically with benzodiazepines.

Question 125: A nurse is providing education to a client who has been prescribed disulfiram. The nurse should warn the client to avoid which of the following products?

Mouthwash containing alcohol (Correct answer)
Foods high in tyramine, such as aged cheeses
Nicotine replacement therapy
Grapefruit juice

Correct answer: Mouthwash containing alcohol

Disulfiram works by inhibiting the enzyme aldehyde dehydrogenase, leading to an accumulation of acetaldehyde if alcohol is consumed. This causes a severe, unpleasant reaction. Many common products, including mouthwash, cough syrups, and some topical preparations, contain alcohol and can trigger this reaction.

Question 126: A nurse is educating a patient about acamprosate for alcohol use disorder. Which statement is most accurate?

Acamprosate works best when started before the patient stops drinking
Acamprosate is metabolized extensively by the liver
Acamprosate helps reduce cravings by modulating glutamate activity (Correct answer)
Acamprosate causes a severe reaction if alcohol is consumed

Correct answer: Acamprosate helps reduce cravings by modulating glutamate activity

Acamprosate modulates glutamatergic neurotransmission to reduce protracted withdrawal symptoms and alcohol cravings after abstinence is established.

Question 127: Which interview technique involves the nurse reflecting back an amplified or exaggerated version of the patient's minimized concern to elicit self-motivating statements?

Double-sided reflection
Simple reflection
Amplified reflection (Correct answer)
Reframing

Correct answer: Amplified reflection

Amplified reflection overstates the patient's position to provoke the patient into defending a less extreme, more change-oriented stance.

Question 128: Allostasis in addiction refers to:

Synaptic pruning caused by chronic substance use
The brain's return to its pre-addiction baseline after abstinence
The acute euphoric response to drug administration
Maintaining stability through change, often resulting in a new, dysregulated set point (Correct answer)

Correct answer: Maintaining stability through change, often resulting in a new, dysregulated set point

Allostasis involves achieving stability through adaptive changes; in addiction, this creates a dysregulated emotional set point requiring drug use to feel 'normal.'

Question 129: Which educational content is most appropriate when teaching a patient about relapse as part of the chronic disease model of addiction?

Relapse means treatment has failed and a more restrictive approach is needed immediately
Any relapse cancels all prior progress made in recovery
Relapse is a sign that the patient lacks willpower and commitment
Relapse is a normal part of many chronic diseases and should prompt a reassessment of the treatment plan (Correct answer)

Correct answer: Relapse is a normal part of many chronic diseases and should prompt a reassessment of the treatment plan

Within the chronic disease model, relapse is viewed similarly to symptom recurrence in other chronic diseases — it signals a need to adjust treatment, not abandon it.

Question 130: What is the first step in creating a treatment plan for addiction?

Conducting a thorough assessment to identify the patient's needs (Correct answer)
Starting with family counseling
Establishing treatment goals without assessment
Providing immediate therapy

Correct answer: Conducting a thorough assessment to identify the patient's needs

The initial and most crucial step in developing an effective addiction treatment plan is conducting a thorough assessment. This comprehensive evaluation identifies the patient's specific substance use patterns, co-occurring mental health conditions, social support, and individual strengths and needs. Without this foundational understanding, any subsequent treatment interventions would lack personalization and may not adequately address the root causes of the addiction.

Question 131: A competent adult patient with a severe alcohol use disorder is insistent on leaving a voluntary inpatient unit against medical advice (AMA). The patient does not meet the criteria for involuntary commitment. Which action by the CARN best fulfills the primary ethical obligations of respecting patient autonomy and promoting safety?

Having security personnel block the patient from leaving the unit.
Informing the patient of the risks, providing discharge instructions and resources, and documenting the event. (Correct answer)
Refusing to provide any prescriptions or follow-up appointments to discourage the patient's decision.
Requiring the patient to wait until a family member arrives to take custody.

Correct answer: Informing the patient of the risks, providing discharge instructions and resources, and documenting the event.

The ethical principle of autonomy requires respecting a competent patient's right to make their own healthcare decisions, including the right to refuse treatment and leave a facility AMA. Since the patient has decision-making capacity and is not an imminent danger to self or others, the nurse's primary duty is to ensure a safe-as-possible discharge. This includes patient education about the risks, providing harm reduction information (e.g., withdrawal symptoms to watch for), offering resources for future care, and thoroughly documenting the informed refusal process.

Question 132: Under 42 CFR Part 2, which of the following disclosures is permitted WITHOUT patient consent?

Reporting to a state health department for public health surveillance
Providing records to a managed care organization for billing
Medical emergency involving immediate threat to life (Correct answer)
Sharing records with a patient's primary care physician

Correct answer: Medical emergency involving immediate threat to life

42 CFR Part 2 permits disclosure without consent in a bona fide medical emergency when the patient's life is at immediate risk.

Question 133: Downregulation of D2 dopamine receptors in the striatum, observed in addiction neuroimaging, contributes to:

Enhanced sensitivity to natural rewards compensating for drug effects
Blunted reward response to natural reinforcers, increasing vulnerability to drug seeking (Correct answer)
Increased inhibitory control over impulsive behaviors
Normalization of the dopamine system toward pre-addiction baseline

Correct answer: Blunted reward response to natural reinforcers, increasing vulnerability to drug seeking

D2 receptor downregulation reduces sensitivity to natural rewards, creating a hypodopaminergic state where only powerful drug stimuli can generate meaningful reward signals.

Question 134: Which pharmacokinetic property of fentanyl makes transdermal patches particularly dangerous when misused (e.g., chewed or injected with extracted gel)?

Fentanyl has low protein binding allowing rapid systemic distribution
Fentanyl undergoes extensive first-pass metabolism when swallowed
Fentanyl has a very long half-life of 48 hours
Fentanyl patches contain a reservoir of drug designed for 72-hour release that can be rapidly absorbed if misused (Correct answer)

Correct answer: Fentanyl patches contain a reservoir of drug designed for 72-hour release that can be rapidly absorbed if misused

Transdermal fentanyl patches contain 72-hour drug reservoirs; chewing or extracting the gel delivers the full dose rapidly, causing fatal overdose.

Question 135: A nurse is using the Clinical Institute Withdrawal Assessment for Alcohol, Revised (CIWA-Ar) scale to assess a patient. The patient scores 12. Based on this score, which of the following is the most appropriate nursing action?

Request an order for a loading dose of a benzodiazepine for severe withdrawal.
Discontinue the assessment as the score is not clinically significant.
Continue to monitor the patient as this indicates mild withdrawal. (Correct answer)
Prepare for immediate seizure precautions and rapid response team activation.

Correct answer: Continue to monitor the patient as this indicates mild withdrawal.

A CIWA-Ar score between 8 and 15 is generally considered to indicate mild to moderate withdrawal. A score of 12 falls into this range, suggesting the need for continued monitoring and potentially symptom-triggered medication, but it does not typically indicate severe withdrawal requiring a loading dose or immediate seizure precautions. Scores of 15 or more usually indicate severe withdrawal.

Question 136: How does pharmacological treatment support behavioral therapies in addiction recovery?

By eliminating the need for long-term therapy
By replacing behavioral therapies with medication
By preventing patients from engaging in any therapy sessions
By supporting patients in managing withdrawal and cravings, enabling them to focus on behavioral therapy (Correct answer)

Correct answer: By supporting patients in managing withdrawal and cravings, enabling them to focus on behavioral therapy

Pharmacological treatments address the physiological aspects of addiction, such as managing severe withdrawal symptoms and reducing intense cravings. By stabilizing these physical challenges, patients are better able to engage mentally and emotionally in behavioral therapies. This integrated approach allows them to focus on developing coping mechanisms and addressing the underlying psychological factors of their addiction.

Question 137: A patient in opioid withdrawal reports severe muscle aches, goosebumps, and yawning. These symptoms are categorized as:

Autonomic instability symptoms
Objective withdrawal signs on the COWS
Subjective withdrawal symptoms (Correct answer)
Signs of opioid-induced hyperalgesia

Correct answer: Subjective withdrawal symptoms

Muscle aches (myalgia), yawning, and gooseflesh (piloerection) are subjective symptoms that patients report during opioid withdrawal.

Question 138: A client with a known history of Bipolar I Disorder and Alcohol Use Disorder is admitted to an inpatient unit. The client is exhibiting pressured speech, psychomotor agitation, and grandiose delusions, and reports not sleeping for three days. What is the nurse's priority intervention?

Administer a long-acting antipsychotic medication as ordered.
Develop a detailed, long-term relapse prevention plan with the client.
Provide a low-stimulation, safe environment and monitor physiological status. (Correct answer)
Initiate a referral to a dual-diagnosis support group.

Correct answer: Provide a low-stimulation, safe environment and monitor physiological status.

In the acute manic phase of bipolar disorder, especially when complicated by substance use, the priority is client safety. This includes protecting the client and others from harm that could result from poor impulse control and agitation. Providing a structured, low-stimulation environment helps to decrease agitation, and monitoring physiological status (e.g., hydration, nutrition, cardiac status) is critical as the client may have neglected self-care. While other interventions are important, they are secondary to ensuring immediate safety and physiological stability.

Question 139: A law enforcement officer presents a photo of an individual to a CARN at the front desk of a substance use disorder (SUD) clinic and asks, "Is this person a patient here?" The officer does not have a court order or a signed patient consent form. According to federal law 42 CFR Part 2, what is the nurse's required response?

Ask the officer to wait while the nurse checks the patient census.
Provide the information, as law enforcement investigations are an exception to confidentiality.
State that federal law prohibits confirming or denying whether any individual is a patient. (Correct answer)
Acknowledge the individual is a patient but refuse to provide any further details.

Correct answer: State that federal law prohibits confirming or denying whether any individual is a patient.

Federal regulation 42 CFR Part 2 provides stringent confidentiality protections for individuals receiving treatment for substance use disorders at federally assisted programs. It prohibits disclosing any information that would identify a person as having or having had a substance use disorder, which includes acknowledging their status as a patient. This protection is stricter than HIPAA and applies even to law enforcement inquiries without a specific court order or patient consent.

Question 140: According to the DSM-5 criteria for Substance Use Disorder (SUD), which of the following best represents the category of 'Impaired Control'?

Continuing to use the substance despite recurrent social or interpersonal problems.
Using the substance in situations where it is physically hazardous.
Developing tolerance, needing more of the substance to achieve the desired effect.
Taking the substance in larger amounts or over a longer period than was originally intended. (Correct answer)

Correct answer: Taking the substance in larger amounts or over a longer period than was originally intended.

The DSM-5 groups its 11 criteria for SUD into four categories: Impaired Control, Social Impairment, Risky Use, and Pharmacological Criteria. Taking more of a substance than intended is a classic example of the 'Impaired Control' category, which also includes unsuccessful efforts to cut down and spending a great deal of time obtaining the substance.

Question 141: A nurse is assessing a patient for opioid withdrawal using the Clinical Opiate Withdrawal Scale (COWS). The patient has a resting heart rate of 105 bpm, reports feeling anxious, and has moderately dilated pupils. Which of these findings would contribute the HIGHEST score to the COWS assessment for that specific item?

Anxiety or Irritability
Restlessness
Resting Pulse Rate
Pupil size (Correct answer)

Correct answer: Pupil size

According to the COWS scale, a resting pulse rate of 101-120 bpm scores a 2. Mild anxiety scores a 1 or 2. Restlessness is scored from 0-5. However, pupils that are moderately dilated score a 2, and pupils so dilated that only the rim of the iris is visible score a 5, which is the highest possible score for any single item on the scale besides restlessness or GI upset. Of the options provided, pupil size has the potential to contribute the highest score for its specific parameter if maximally dilated.

Question 142: The role of the hippocampus in addiction is best characterized as:

Regulating respiratory depression during opioid overdose
Encoding and contextual retrieval of drug-related memories that trigger craving (Correct answer)
Controlling the autonomic symptoms of withdrawal
Generating the initial euphoric response to drugs

Correct answer: Encoding and contextual retrieval of drug-related memories that trigger craving

The hippocampus encodes episodic and contextual memories of drug use; these memories can be retrieved by environmental contexts, powerfully triggering craving and relapse.

Question 143: A nurse in a primary care clinic wants to implement a quick screening tool for unhealthy alcohol use. Which tool is known for its brevity (4 questions) and focus on identifying lifetime alcohol problems rather than just current drinking patterns?

CAGE Questionnaire (Correct answer)
AUDIT-C (Alcohol Use Disorders Identification Test - Consumption)
COWS (Clinical Opiate Withdrawal Scale)
CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol, Revised)

Correct answer: CAGE Questionnaire

The CAGE questionnaire is a widely used, four-question screening tool. A key feature is that its questions probe for lifetime problems related to alcohol use (e.g., 'Have you ever felt you should Cut down?'). This contrasts with tools like the AUDIT-C, which focuses more on recent consumption patterns. CIWA-Ar and COWS are assessment tools for withdrawal, not screening tools for unhealthy use.

Question 144: A patient with co-occurring cocaine use disorder and depression has been abstinent for 3 weeks but reports persistent anhedonia and low mood. The nurse should FIRST:

Start an SSRI immediately as this confirms independent major depression
Reassess after 4-6 weeks of abstinence before diagnosing independent depression (Correct answer)
Recommend inpatient psychiatric hospitalization for mood stabilization
Attribute symptoms entirely to post-acute withdrawal and provide no intervention

Correct answer: Reassess after 4-6 weeks of abstinence before diagnosing independent depression

Cocaine-induced depression can persist beyond 2 weeks; reassessing after 4-6 weeks of abstinence allows clinicians to distinguish substance-induced from independent depressive disorders before initiating antidepressant pharmacotherapy.

Question 145: Why is motivational interviewing an effective technique in addiction treatment?

It discourages patients from considering recovery options
It focuses on imposing treatment goals without patient input
It encourages patients to reflect on their reasons for change and increase motivation (Correct answer)
It forces the patient to commit to treatment

Correct answer: It encourages patients to reflect on their reasons for change and increase motivation

Motivational interviewing is highly effective in addiction treatment because it is a patient-centered approach that helps individuals explore and resolve their ambivalence about change. By guiding patients to articulate their own reasons for recovery and identify discrepancies between their values and current behavior, it intrinsically builds and strengthens their motivation. This technique empowers patients to commit to and sustain sobriety on their own terms.

Question 146: How do benzodiazepines affect the treatment of substance use disorders?

They eliminate the need for therapy sessions
They accelerate the process of rehabilitation
They help manage alcohol withdrawal symptoms but can lead to dependence if used long-term (Correct answer)
They prevent the need for detoxification

Correct answer: They help manage alcohol withdrawal symptoms but can lead to dependence if used long-term

Benzodiazepines are primarily used in the treatment of substance use disorders to manage acute alcohol withdrawal symptoms, such as tremors, seizures, and delirium, due to their sedative and anxiolytic properties. However, their use requires careful monitoring because long-term or unsupervised use can lead to physical dependence and potential misuse. Therefore, they are typically prescribed for short durations during the detoxification phase to ensure patient safety and comfort.

Question 147: Which statement correctly describes acamprosate's mechanism in treating alcohol use disorder?

It blocks opioid receptors to reduce alcohol cravings
It inhibits alcohol metabolism to maintain sobriety
It causes an aversive reaction when alcohol is consumed
It modulates glutamate and GABA activity to reduce post-acute withdrawal symptoms (Correct answer)

Correct answer: It modulates glutamate and GABA activity to reduce post-acute withdrawal symptoms

Acamprosate restores balance between glutamate (excitatory) and GABA (inhibitory) neurotransmission, alleviating protracted abstinence symptoms like anxiety and dysphoria.

Question 148: Why is patient involvement crucial in treatment planning?

Because it ensures the plan aligns with the patient’s needs and values (Correct answer)
Because patients cannot make decisions about their treatment
Because it reduces the number of treatment options needed
Because patients are responsible for their recovery regardless of the plan

Correct answer: Because it ensures the plan aligns with the patient’s needs and values

Patient involvement is crucial in treatment planning because it empowers individuals and fosters a sense of ownership over their recovery journey. When patients actively participate in developing their plan, it ensures that the goals and strategies align with their personal values, preferences, and life circumstances. This collaborative approach significantly increases motivation, commitment, and the likelihood of successful long-term engagement in treatment.

Question 149: A nurse is educating the spouse of a person with a severe alcohol use disorder who is resistant to treatment. The nurse introduces the Community Reinforcement Approach and Family Training (CRAFT) model. What is the primary goal of this modality for the spouse?

To practice 'tough love' and detachment to allow the person to hit rock bottom.
To organize a surprise, confrontational intervention with other family and friends.
To learn skills that positively reinforce sobriety and encourage the person to enter treatment. (Correct answer)
To focus solely on their own recovery and well-being through a 12-step program like Al-Anon.

Correct answer: To learn skills that positively reinforce sobriety and encourage the person to enter treatment.

The Community Reinforcement Approach and Family Training (CRAFT) model is an evidence-based therapy that teaches concerned significant others (CSOs) positive, non-confrontational strategies to influence their loved one's behavior. The three main goals are to help the person reduce their substance use, engage them in treatment, and improve the CSO's own quality of life. It focuses on positive reinforcement and communication, rather than confrontation or detachment.

Question 150: A patient with opioid use disorder on methadone maintenance is prescribed rifampin for tuberculosis. What pharmacokinetic interaction should the nurse anticipate?

Rifampin displaces methadone from protein-binding sites
Rifampin inhibits CYP3A4, increasing methadone levels and risk of overdose
Rifampin enhances renal excretion of methadone
Rifampin induces CYP3A4, reducing methadone levels and potentially precipitating withdrawal (Correct answer)

Correct answer: Rifampin induces CYP3A4, reducing methadone levels and potentially precipitating withdrawal

Rifampin is a potent CYP3A4 inducer; it accelerates methadone metabolism, significantly lowering plasma levels and triggering withdrawal symptoms.

Question 151: Which approach to trauma-informed care is MOST important when working with patients with co-occurring PTSD and substance use disorders?

Requiring patients to process trauma before addressing substance use
Minimizing discussion of trauma to avoid triggering relapse
Using exposure-based techniques in early treatment regardless of substance use status
Creating a safe environment that emphasizes trust, choice, and collaboration (Correct answer)

Correct answer: Creating a safe environment that emphasizes trust, choice, and collaboration

Trauma-informed care emphasizes creating physical and emotional safety, building trust, offering choice and collaboration, and empowering patients — foundational elements especially critical for patients with co-occurring PTSD and substance use disorders.
