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

Question 1: Methadone's utility in opioid use disorder is partly due to its long half-life. What is the approximate half-life of methadone?

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

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 2: Allostasis in addiction refers to:

The brain's return to its pre-addiction baseline after abstinence
Synaptic pruning caused by chronic substance use
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 3: Why is motivational interviewing an effective technique in addiction treatment?

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
It discourages patients from considering recovery options

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 4: A nurse notes that a patient in alcohol withdrawal is experiencing formication (sensation of insects crawling on the skin). This finding is best classified as:

Alcohol hallucinosis
A tactile hallucination (Correct answer)
A visual hallucination
Delirium tremens

Correct answer: A tactile hallucination

Formication is a tactile hallucination involving the sensation of things crawling on or under the skin, distinct from visual or auditory hallucinations.

Question 5: Which withdrawal syndrome is considered life-threatening without appropriate medical management and may include seizures and delirium tremens?

Cannabis withdrawal
Opioid withdrawal
Alcohol withdrawal (Correct answer)
Stimulant withdrawal

Correct answer: Alcohol withdrawal

Alcohol withdrawal is the most medically dangerous common withdrawal syndrome and can progress to seizures and delirium tremens with significant mortality if untreated.

Question 6: Kappa-opioid receptor activation is associated with which affective state that contributes to the negative reinforcement cycle of addiction?

Sedation and sleep
Anxiety reduction and calm
Euphoria and pleasure
Dysphoria and aversion (Correct answer)

Correct answer: Dysphoria and aversion

Kappa-opioid receptor activation produces dysphoria and aversive states, which during withdrawal motivates drug use to escape negative affect (negative reinforcement).

Question 7: What is the significance of relapse prevention education in addiction treatment?

To prevent the patient from leaving their home environment
To help the patient recognize triggers and avoid relapse situations (Correct answer)
To ignore any future challenges
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 8: The process of extinction learning in addiction treatment (such as cue exposure therapy) targets which neurobiological mechanism?

Reversing histone acetylation in the prefrontal cortex
Forming a new inhibitory memory that competes with the drug-cue association (Correct answer)
Permanently suppressing dopamine release in the NAc
Erasing the original drug memory engram completely

Correct answer: Forming a new inhibitory memory that competes with the drug-cue association

Extinction does not erase original drug-cue memories but forms new inhibitory associations in the prefrontal cortex that suppress conditioned responses — explaining why relapse remains possible.

Question 9: Which scenario represents a violation of professional boundaries in addiction nursing?

A nurse uses motivational interviewing techniques to address ambivalence
A nurse shares general educational information about relapse prevention with a patient's family
A nurse provides a patient in financial distress with their personal cell phone number for after-hours contact (Correct answer)
A nurse attends a patient's graduation ceremony as a formal facility-sponsored event

Correct answer: A nurse provides a patient in financial distress with their personal cell phone number for after-hours contact

Providing personal contact information to patients blurs professional boundaries and creates a dual relationship outside the therapeutic setting.

Question 10: Which communication technique in Motivational Interviewing (MI) involves reflecting back a deeper meaning or emotion beneath what the patient explicitly stated?

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

Correct answer: Complex reflection

Complex reflections add meaning, emotion, or interpretation beyond the patient's literal words to deepen engagement and promote insight.

Question 11: A patient with alcohol use disorder has been abstinent for 6 months and wants to stop taking acamprosate. The nurse should advise:

Continue for at least 12 months total as relapse risk remains elevated, then discuss with provider (Correct answer)
Discontinue immediately since alcohol cravings typically resolve after 6 months
Switch to naltrexone before stopping acamprosate
Taper slowly over 4 weeks to prevent rebound seizures

Correct answer: Continue for at least 12 months total as relapse risk remains elevated, then discuss with provider

Guidelines recommend acamprosate for at least 12 months to address prolonged post-acute withdrawal; stopping early increases relapse risk since neurochemical dysregulation can persist.

Question 12: 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?

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

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 13: 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?

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

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 14: Which screening tool uses the mnemonic CAGE to assess alcohol use disorder?

AUDIT
MAST
DAST-10
CAGE questionnaire (Correct answer)

Correct answer: CAGE questionnaire

The CAGE questionnaire uses four questions about Cutting down, Annoyance, Guilt, and Eye-opener to screen for alcohol problems.

Question 15: The 'incentive salience' theory of addiction proposes that compulsive drug seeking is driven by:

Excessive 'wanting' attributed to drug cues, dissociated from actual drug 'liking' (Correct answer)
Serotonin depletion in the dorsal raphe nucleus
GABA receptor downregulation in the hippocampus
The pleasure derived from drug effects diminishing over time

Correct answer: Excessive 'wanting' attributed to drug cues, dissociated from actual drug 'liking'

Incentive salience theory (Robinson & Berridge) distinguishes 'wanting' (dopamine-mediated craving) from 'liking' (opioid-mediated pleasure), explaining why craving persists despite reduced pleasure.

Question 16: A patient with co-occurring major depression and opioid use disorder is started on buprenorphine/naloxone. Which additional benefit of this medication is particularly relevant to this patient's psychiatric comorbidity?

Buprenorphine has demonstrated antidepressant properties through kappa-opioid receptor antagonism (Correct answer)
Buprenorphine has no psychotropic effects beyond addiction treatment
Naloxone component treats depression independently
Buprenorphine increases serotonin levels equivalent to SSRIs

Correct answer: Buprenorphine has demonstrated antidepressant properties through kappa-opioid receptor antagonism

Buprenorphine's antagonism at kappa-opioid receptors, which are implicated in depressive states, may contribute to antidepressant effects in patients with co-occurring depression and opioid use disorder.

Question 17: A patient with methamphetamine use disorder asks about pharmacological treatment options. The addictions nurse should inform the patient that:

Methadone is used as maintenance therapy for stimulant dependence
Naltrexone is the first-line approved treatment for stimulant use disorder
No FDA-approved pharmacotherapy currently exists for stimulant use disorder (Correct answer)
Bupropion is FDA-approved specifically for meth use disorder

Correct answer: No FDA-approved pharmacotherapy currently exists for stimulant use disorder

As of current guidelines, there is no FDA-approved medication for stimulant use disorder; treatment relies primarily on behavioral interventions such as contingency management.

Question 18: What is the role of methadone in the treatment of opioid addiction?

To cure opioid addiction instantly
To increase opioid use in patients
To cause immediate detoxification
To reduce cravings and withdrawal symptoms, helping patients stabilize (Correct answer)

Correct answer: To reduce cravings and withdrawal symptoms, helping patients stabilize

Methadone is a long-acting opioid agonist used in Medication-Assisted Treatment (MAT) for opioid addiction. Its role is to reduce opioid cravings and prevent severe withdrawal symptoms without producing the euphoric 'high' associated with illicit opioids. By stabilizing brain chemistry, methadone allows patients to function normally, engage in counseling, and focus on their recovery without the constant preoccupation with obtaining and using opioids.

Question 19: 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?

Gather more definitive proof over the next several shifts to build a stronger case.
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.
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 20: When comparing the pharmacology of nicotine delivery via electronic cigarettes (vaping) versus traditional combustible cigarettes, which of the following is most accurate?

E-cigarettes are a non-addictive alternative to smoking.
Both methods deliver identical amounts of nicotine per puff.
Traditional cigarettes deliver carbon monoxide, while e-cigarettes do not. (Correct answer)
Vaping delivers nicotine to the brain more rapidly than smoking.

Correct answer: Traditional cigarettes deliver carbon monoxide, while e-cigarettes do not.

The combustion of tobacco in traditional cigarettes produces thousands of chemicals, including carbon monoxide and tar, which are largely absent in the aerosol from e-cigarettes. While both deliver the addictive substance nicotine, the byproducts of combustion are the primary source of smoking-related harm. Nicotine delivery from vaping can be slower and less efficient than from smoking, especially in new users, and it is still an addictive substance.

Question 21: What role does family involvement play in addiction treatment planning?

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

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

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

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 23: A patient with an extensive opioid use history presents with pinpoint pupils, decreased respirations of 8/min, and unresponsiveness. Which assessment action is the nurse's first priority?

Call the physician for medication orders
Assess level of consciousness with sternal rub
Administer naloxone per protocol (Correct answer)
Obtain a urine drug screen

Correct answer: Administer naloxone per protocol

Signs of opioid overdose with respiratory depression require immediate naloxone administration to reverse life-threatening CNS and respiratory depression.

Question 24: What is a key indicator of opioid addiction during assessment?

Lack of interest in social activities
Using opioids in larger amounts and experiencing withdrawal symptoms (Correct answer)
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 25: A nurse performing an addiction assessment documents that a patient continues using substances despite a physician-confirmed diagnosis of alcohol-related liver disease. Under DSM-5 criteria, this finding best satisfies which criterion?

Withdrawal
Tolerance
Use despite persistent physical health consequences (Correct answer)
Failure to fulfill major role obligations

Correct answer: Use despite persistent physical health consequences

Continued use despite a known physical health condition worsened by substance use meets the DSM-5 criterion of use despite persistent or recurrent physical problems.

Question 26: Which statement accurately describes the concept of 'therapeutic limit setting' in addiction nursing practice?

Using negative reinforcement to extinguish drug-seeking behaviors
Refusing to engage with patients who are actively using substances
Establishing clear, consistent boundaries that protect the therapeutic relationship and patient safety while conveying respect (Correct answer)
Setting strict punitive consequences to modify manipulative behavior

Correct answer: Establishing clear, consistent boundaries that protect the therapeutic relationship and patient safety while conveying respect

Therapeutic limit setting involves communicating clear, non-punitive expectations that maintain safety and structure while preserving the dignity of the nurse-patient relationship.

Question 27: A nurse is using motivational interviewing during a patient education session. Which nurse statement best reflects the MI principle of 'affirmation'?

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

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 28: Why is patient education important in addiction recovery?

To encourage patients to abandon their treatment plan
To help the patient avoid all types of therapy
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 29: A nurse assessing a patient's readiness to change asks, 'On a scale of 0-10, how important is it for you to change your drinking?' This technique is called:

Reflective listening
Decisional balancing
Importance and confidence rulers (Correct answer)
Affirmation

Correct answer: Importance and confidence rulers

Importance and confidence rulers are motivational interviewing tools that use scaling questions to elicit and explore ambivalence about change.

Question 30: A nurse is educating a patient starting buprenorphine/naloxone (Suboxone). Which instruction is most critical to prevent precipitated withdrawal?

Swallow the film whole for best effect
Wait until experiencing moderate withdrawal symptoms (COWS score ≥8-12) before taking the first dose (Correct answer)
Take the first dose immediately after using opioids
Take with food to improve absorption

Correct answer: Wait until experiencing moderate withdrawal symptoms (COWS score ≥8-12) before taking the first dose

Buprenorphine must not be given until moderate withdrawal is present; its high receptor affinity can displace full agonists and precipitate acute withdrawal.

Question 31: A nurse working with a patient with co-occurring borderline personality disorder and alcohol use disorder should prioritize which treatment approach?

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

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 32: A nurse notices a patient with major depressive disorder has significantly increased alcohol use over the past week. The most appropriate initial intervention is:

Explore the relationship between depressive symptoms and increased alcohol use (Correct answer)
Refer to a detox program and discontinue psychiatric treatment
Discharge the patient for violating treatment rules
Increase the antidepressant dose without further assessment

Correct answer: Explore the relationship between depressive symptoms and increased alcohol use

Exploring the relationship between mood symptoms and substance use is essential to understanding the functional connection and guiding integrated treatment.

Question 33: Which assessment finding best indicates that a patient in alcohol withdrawal has progressed to delirium tremens (DTs)?

Mild hand tremor and anxiety
Insomnia and diaphoresis
Nausea and mild hypertension
Global confusion, agitation, fever, and autonomic instability (Correct answer)

Correct answer: Global confusion, agitation, fever, and autonomic instability

Delirium tremens is defined by the triad of confusion, autonomic instability, and agitation, typically occurring 48–96 hours after last drink and carrying mortality risk.

Question 34: A nurse in an addiction program is asked by law enforcement to confirm whether a specific individual is enrolled in the program. Under 42 CFR Part 2, the nurse should:

Confirm or deny enrollment since law enforcement has authority to access this information
Neither confirm nor deny that the individual is a patient without a court order or patient consent (Correct answer)
Provide enrollment information if the officer shows a badge and states it is an investigation
Release the information only if the patient is suspected of a violent crime

Correct answer: Neither confirm nor deny that the individual is a patient without a court order or patient consent

42 CFR Part 2 prohibits even confirming or denying program enrollment to law enforcement without a specific court order or patient consent.

Question 35: Which statement about Medication-Assisted Treatment (MAT) and recovery is most accurate?

MAT is only appropriate for acute detoxification and should not be used long-term
Participation in 12-Step programs requires patients to discontinue MAT medications
Patients maintained on MAT medications are not in 'true' recovery
MAT combined with counseling consistently improves long-term recovery outcomes (Correct answer)

Correct answer: MAT combined with counseling consistently improves long-term recovery outcomes

Strong evidence shows that MAT (buprenorphine, methadone, naltrexone) combined with psychosocial treatment significantly improves retention, reduces relapse, and lowers mortality.

Question 36: Which mechanism explains why alcohol withdrawal can be life-threatening, unlike opioid withdrawal?

Alcohol depletes glycogen stores leading to fatal hypoglycemia
Alcohol downregulates dopamine receptors causing severe dysphoria
Alcohol causes upregulation of GABA-A receptors leading to CNS hyperexcitability upon cessation (Correct answer)
Alcohol causes permanent destruction of serotonin neurons

Correct answer: Alcohol causes upregulation of GABA-A receptors leading to CNS hyperexcitability upon cessation

Chronic alcohol use downregulates GABA-A receptors and upregulates NMDA receptors; abrupt cessation causes CNS hyperexcitability, risking seizures and death.

Question 37: 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)
'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.'
'Naloxone will work immediately and keep the person safe for at least 24 hours.'

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 38: According to the DSM-5, the severity of a substance use disorder is determined by the number of diagnostic criteria met within a 12-month period. A patient who meets four criteria would be diagnosed with which level of severity?

Moderate (Correct answer)
At-Risk
Mild
Severe

Correct answer: Moderate

The DSM-5 specifies the severity of a substance use disorder based on the number of criteria met: 2-3 criteria indicate a mild disorder, 4-5 criteria indicate a moderate disorder, and 6 or more criteria indicate a severe disorder. Therefore, a patient meeting four criteria falls into the moderate category.

Question 39: What is the primary function of pharmacological interventions in addiction treatment?

To replace the patient’s addiction with another substance
To promote further substance use
To manage withdrawal symptoms, reduce cravings, and support long-term sobriety (Correct answer)
To prevent the patient from accessing treatment

Correct answer: To manage withdrawal symptoms, reduce cravings, and support long-term sobriety

The primary function of pharmacological interventions in addiction treatment is to provide crucial support for patients managing substance use disorders. These medications help by alleviating severe withdrawal symptoms, significantly reducing intense cravings, and addressing co-occurring mental health conditions. By stabilizing the patient physically and psychologically, pharmacological interventions enable them to engage more effectively in behavioral therapies and work towards long-term sobriety.

Question 40: A CARN working with adolescents must balance parental rights with the minor patient's confidentiality. Which federal protection most directly governs substance use disorder treatment records for minors?

FERPA (Family Educational Rights and Privacy Act)
42 CFR Part 2, which may protect minor SUD records from parental disclosure (Correct answer)
HIPAA, which gives parents full access to all minor health records
State mandatory reporting laws, which always supersede confidentiality

Correct answer: 42 CFR Part 2, which may protect minor SUD records from parental disclosure

42 CFR Part 2 can protect a minor's SUD treatment records from disclosure to parents when the minor has independently sought treatment.

Question 41: A CARN suspects a patient is being coerced by a partner into entering treatment. The most appropriate initial response is to:

Proceed with treatment admission since the patient is physically present and consenting
Assess the patient's safety and voluntariness of consent in a private setting (Correct answer)
Contact the partner to discuss the situation and clarify intentions
Consult with the treatment team before meeting with the patient

Correct answer: Assess the patient's safety and voluntariness of consent in a private setting

Voluntary consent requires assessment of coercion; the nurse must assess the patient privately to ensure genuine willingness to participate.

Question 42: A CARN is treating a patient with borderline personality disorder (BPD) and opioid use disorder. Which therapeutic approach has the strongest evidence for treating BPD in this population?

Standard CBT without modification
Dialectical Behavior Therapy (DBT) (Correct answer)
Psychoanalytic therapy
12-step facilitation alone

Correct answer: Dialectical Behavior Therapy (DBT)

DBT was originally developed for BPD and has been adapted for co-occurring substance use disorders, with strong evidence supporting its effectiveness.

Question 43: During a motivational assessment, a patient states: 'I know drinking is causing problems, but I'm not sure I want to quit.' This statement best reflects which stage of the Transtheoretical Model?

Precontemplation
Action
Contemplation (Correct answer)
Preparation

Correct answer: Contemplation

Acknowledging problems while being ambivalent about change is the hallmark of the contemplation stage.

Question 44: The Community Reinforcement Approach (CRA) for substance use disorders primarily works by:

Teaching mindfulness meditation to manage cravings
Using aversive conditioning to create discomfort with substance use
Restructuring environmental rewards to make sobriety more rewarding than use (Correct answer)
Confronting denial through structured group feedback

Correct answer: Restructuring environmental rewards to make sobriety more rewarding than use

CRA rearranges the patient's environment so that sobriety becomes more reinforcing than substance use by enhancing prosocial activities, relationships, and vocational functioning.

Question 45: A patient declines a recommended step-down to a less intensive level of care. The nurse's best response is to:

Immediately involve the ethics committee to resolve the dispute
Discharge the patient for refusing the clinical recommendation
Document the decision and explore the patient's concerns and fears about stepping down (Correct answer)
Override the patient's wishes because clinical judgment must prevail

Correct answer: Document the decision and explore the patient's concerns and fears about stepping down

Exploring the patient's concerns respects autonomy while allowing the nurse to address fears, provide education, and build agreement through shared decision-making.

Question 46: When a patient in a recovery program experiences a relapse, the nurse's PRIORITY intervention is to:

Administer the predetermined behavioral consequence per the program contract
Discharge the patient for violating the treatment contract
Assess safety and detox needs, then reassess and modify the treatment plan (Correct answer)
Recommend the patient attend 90 AA meetings in 90 days

Correct answer: Assess safety and detox needs, then reassess and modify the treatment plan

A relapse requires immediate safety assessment (including need for detoxification) and clinical reassessment of the treatment plan, as relapse is an expected part of the chronic disease course.

Question 47: Which receptor subtype is primarily responsible for the euphoric effects of opioids?

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

Correct answer: Mu (μ)

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

Question 48: A CARN suspects a patient is selling their prescribed buprenorphine. The nurse's initial response should be to:

Report the patient to law enforcement without clinical evaluation
Conduct a clinical assessment, discuss concerns with the patient, and consult the prescriber (Correct answer)
Immediately discontinue the prescription without discussion
Ignore the concern since buprenorphine diversion is common

Correct answer: Conduct a clinical assessment, discuss concerns with the patient, and consult the prescriber

Clinical assessment and direct therapeutic discussion with the patient, followed by prescriber consultation, balances patient care needs with program integrity.

Question 49: Which situation would most appropriately trigger an ethics consultation in addiction nursing practice?

Disagreement between nursing staff about the best approach to a patient interaction
A patient requesting discharge earlier than the treatment team recommends
A patient refusing a recommended medication change
Ongoing conflict about treatment goals between a patient, family, and clinical team (Correct answer)

Correct answer: Ongoing conflict about treatment goals between a patient, family, and clinical team

Ethics consultations are indicated when there is genuine conflict among stakeholders about values, goals, or the ethical course of action in complex cases.

Question 50: A nurse is facilitating a Matrix Model group for stimulant use disorder. This evidence-based approach combines which elements?

Pharmacotherapy and aversive conditioning
Individual psychoanalysis and inpatient detoxification
Hypnotherapy and peer mentorship only
CBT, family education, 12-step facilitation, and relapse prevention (Correct answer)

Correct answer: CBT, family education, 12-step facilitation, and relapse prevention

The Matrix Model integrates cognitive-behavioral therapy, relapse prevention, family involvement, and 12-step participation into a structured outpatient program for stimulant use disorder.

Question 51: A nurse is caring for a 17-year-old client seeking treatment for an opioid use disorder. The client's parents call the unit demanding to know their child's diagnosis and treatment plan. According to the federal regulation 42 CFR Part 2, what is the nurse's most appropriate response?

Provide the parents with general information about the treatment program but not the client's specific diagnosis.
Explain that because the client is a minor, the parents have a legal right to all of their child's health information.
Request that the parents provide proof of guardianship before releasing any information.
Inform the parents that without the client's specific written consent, no information can be disclosed. (Correct answer)

Correct answer: Inform the parents that without the client's specific written consent, no information can be disclosed.

Federal regulation 42 CFR Part 2 provides stringent confidentiality protections for patients receiving treatment for substance use disorders in federally assisted programs. These protections are often more strict than HIPAA. For a minor who has the legal capacity to apply for and obtain substance use disorder treatment on their own under state law, consent for disclosure must be given by the minor patient. Disclosing any information without the client's express written consent would be a violation of this federal law.

Question 52: In Marlatt's relapse prevention model, 'seemingly irrelevant decisions' (SIDs) refers to:

Minor relapses that do not significantly impact overall recovery
Decisions made while under the influence of substances
Life decisions unrelated to substance use
Small choices that cumulatively set up high-risk relapse situations (Correct answer)

Correct answer: Small choices that cumulatively set up high-risk relapse situations

SIDs are small, apparently innocent choices (e.g., driving past a dealer's house 'by accident') that gradually increase proximity to relapse situations.

Question 53: Downregulation of D2 dopamine receptors in the striatum, observed in addiction neuroimaging, contributes to:

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

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 54: A nurse is counseling a patient about naloxone home use. Which instruction is most important regarding repeat dosing?

A single dose of naloxone is always sufficient and redosing is never needed
Naloxone's duration of action may be shorter than the opioid's, requiring repeat doses every 2-3 minutes if the patient does not respond (Correct answer)
Naloxone should be administered orally for fastest onset
Naloxone should only be given by healthcare professionals

Correct answer: Naloxone's duration of action may be shorter than the opioid's, requiring repeat doses every 2-3 minutes if the patient does not respond

Naloxone's duration of action (30-90 minutes) is often shorter than many opioids, so repeat dosing every 2-3 minutes may be necessary, and emergency services must always be called.

Question 55: The nurse is administering IV lorazepam to a patient in severe alcohol withdrawal. Which complication specific to IV lorazepam requires close monitoring?

Hypoglycemia
QTc prolongation
Propylene glycol toxicity with high cumulative doses (Correct answer)
Rhabdomyolysis

Correct answer: Propylene glycol toxicity with high cumulative doses

IV lorazepam formulations contain propylene glycol as a solvent, and high cumulative doses can cause propylene glycol toxicity including metabolic acidosis and renal injury.

Question 56: Naltrexone is contraindicated in a patient who:

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

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 57: 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?

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

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 58: A patient completing a medically supervised withdrawal asks why continued treatment is recommended after detoxification. The best nurse response is:

'Continued treatment is a legal requirement after detox in most states.'
'You only need follow-up if you used heroin; other substances are different.'
'Detoxification addresses physical dependence but not the psychological and behavioral aspects of addiction.' (Correct answer)
'Detoxification alone has high long-term success rates for most patients.'

Correct answer: 'Detoxification addresses physical dependence but not the psychological and behavioral aspects of addiction.'

Detoxification treats physical dependence but does not address the psychological, behavioral, and social factors that drive addiction and relapse.

Question 59: When using the CRAFFT screening tool with adolescent patients, the nurse should understand it is designed to assess risk related to:

Tobacco dependence severity
Alcohol and other substance use while in cars, alone, or to relax/forget (Correct answer)
Gambling and behavioral addictions
Chronic pain and opioid misuse

Correct answer: Alcohol and other substance use while in cars, alone, or to relax/forget

CRAFFT screens adolescents for substance use risk using questions about riding in a Car, using substances Alone, to Relax, Forget, among other triggers.

Question 60: A patient receiving extended-release naltrexone (Vivitrol) for opioid use disorder requires surgery. The CARN nurse should advise the surgical team that:

Non-opioid analgesia must be used and opioids will be ineffective at standard doses (Correct answer)
The injection must be reversed before any procedure
Higher-than-usual opioid doses may be needed and sedation risk is increased
Standard opioid doses will be effective for pain control

Correct answer: Non-opioid analgesia must be used and opioids will be ineffective at standard doses

Naltrexone blocks opioid receptors, so standard opioid analgesics will be ineffective; non-opioid pain management strategies are preferred and the surgical team must be informed.

Question 61: A nurse is implementing contingency management for a patient with stimulant use disorder. The core mechanism of this intervention is:

Using vouchers or prizes to reinforce abstinence (Correct answer)
Building a therapeutic alliance through empathy
Teaching relapse prevention cognitive skills
Providing insight into unconscious motivations

Correct answer: Using vouchers or prizes to reinforce abstinence

Contingency management uses operant conditioning—rewarding verified abstinence with vouchers or prizes—to reinforce drug-free behavior.

Question 62: A nurse is treating a patient with opioid use disorder and PTSD. Which therapeutic modality has the STRONGEST evidence base for treating both conditions concurrently?

Psychodynamic therapy
12-step facilitation
Seeking Safety (Correct answer)
Supportive counseling

Correct answer: Seeking Safety

Seeking Safety is a present-focused cognitive-behavioral therapy with strong evidence specifically designed for individuals with co-occurring PTSD and substance use disorders.

Question 63: Which treatment model is considered the gold standard for clients with co-occurring substance use and severe mental illness, emphasizing that the same clinicians or team provide care for both disorders concurrently?

The Four-Quadrant Model
Sequential Treatment
Parallel Treatment
Integrated Dual Disorder Treatment (IDDT) (Correct answer)

Correct answer: Integrated Dual Disorder Treatment (IDDT)

Integrated Dual Disorder Treatment (IDDT) is the evidence-based, gold-standard model where the same team of providers delivers both mental health and substance abuse services simultaneously. This approach avoids the fragmentation of care seen in Sequential (one disorder treated, then the other) and Parallel (two separate teams treat disorders at the same time) models, leading to better engagement and outcomes.

Question 64: 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?

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

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 65: When educating an adolescent patient about substance use disorder, which approach is most developmentally appropriate?

Focusing primarily on legal consequences of substance use
Incorporating peer perspectives, brief motivational interventions, and interactive formats (Correct answer)
Using the same didactic methods used with adults for consistency
Requiring parental attendance at all educational sessions without exception

Correct answer: Incorporating peer perspectives, brief motivational interventions, and interactive formats

Adolescents respond best to interactive, peer-relevant educational approaches combined with motivational enhancement tailored to their developmental stage.

Question 66: A CARN who is in personal recovery from alcohol use disorder begins working at a substance use treatment center. Which action is MOST ethically appropriate regarding disclosure?

Disclose personal recovery status to all patients to build rapport
Never disclose personal recovery status under any circumstances
Disclose only to supervisors but maintain confidentiality with patients
Use professional judgment to determine if selective disclosure serves therapeutic goals (Correct answer)

Correct answer: Use professional judgment to determine if selective disclosure serves therapeutic goals

Self-disclosure of personal recovery should be guided by whether it serves the patient's therapeutic interests, not the nurse's own needs.

Question 67: 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?

"You need to find a healthier way to relax or you'll face serious health consequences."
"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)
"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."

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 68: A CARN is working at a community clinic with a patient who has a severe opioid use disorder, continues to inject heroin daily, and is not currently interested in abstinence-based treatment. Which of the following interventions is most consistent with a harm reduction approach?

Educating the patient on safer injection techniques and providing a naloxone kit. (Correct answer)
Arranging a family meeting to confront the patient about their drug use.
Insisting the patient enter a residential treatment program immediately.
Providing education on the stages of change and waiting for the patient to reach the action stage.

Correct answer: Educating the patient on safer injection techniques and providing a naloxone kit.

Harm reduction aims to minimize the negative health and social impacts of drug use without necessarily requiring cessation. Providing safer use supplies (clean needles) and an overdose reversal medication (naloxone) are core harm reduction strategies that meet the patient where they are and prioritize immediate safety.

Question 69: A 28-year-old patient with opioid use disorder who is pregnant is asking about treatment options. Which statement reflects current evidence-based practice?

Extended-release naltrexone is the safest MOUD option during pregnancy
Opioid detoxification (withdrawal) is recommended in the first trimester to protect fetal development
Opioid use disorder in pregnancy should be managed without medications to avoid fetal exposure
Buprenorphine or methadone maintenance is preferred over detoxification because it reduces fetal distress and preterm labor risk (Correct answer)

Correct answer: Buprenorphine or methadone maintenance is preferred over detoxification because it reduces fetal distress and preterm labor risk

ACOG and SAMHSA recommend opioid agonist maintenance (methadone or buprenorphine) during pregnancy because abrupt withdrawal increases risk of fetal distress, miscarriage, and preterm birth.

Question 70: A nurse is providing relapse prevention education. Which cognitive-behavioral strategy teaches patients to recognize internal and external triggers before a craving escalates?

Urge surfing
Contingency management
Functional analysis of substance use (Correct answer)
Cue exposure and response prevention

Correct answer: Functional analysis of substance use

Functional analysis identifies the antecedents (triggers), behaviors, and consequences of substance use, forming the foundation of relapse prevention planning.

Question 71: A patient in early recovery asks why they should avoid over-the-counter cough medicines containing dextromethorphan (DXM). What is the best explanation?

DXM causes liver damage in recovering patients
DXM interacts with most antibiotics
DXM is only dangerous when combined with food
DXM has dissociative properties and abuse potential that can trigger relapse (Correct answer)

Correct answer: DXM has dissociative properties and abuse potential that can trigger relapse

DXM is a dissociative agent with significant abuse potential and can trigger relapse or cross-addiction in recovering individuals.

Question 72: A patient in a therapeutic community (TC) for methamphetamine addiction repeatedly violates community norms. According to TC philosophy, this behavior is BEST addressed by:

Increasing the patient's medication dose
Immediate discharge from the program
Peer-run encounter groups to confront the behavior (Correct answer)
One-on-one sessions with the nurse only

Correct answer: Peer-run encounter groups to confront the behavior

Therapeutic communities use the community itself as the agent of change, with peer encounter groups being a core method for addressing problematic behavior.

Question 73: The 'abstinence violation effect' (AVE) describes which phenomenon?

The therapeutic benefit of short-term, planned abstinence periods
Legal consequences for violating conditions of probation or parole
Physical withdrawal symptoms that emerge after stopping substance use
Guilt and self-attribution following a lapse that can precipitate full relapse (Correct answer)

Correct answer: Guilt and self-attribution following a lapse that can precipitate full relapse

The AVE refers to feelings of guilt, shame, and perceived personal failure following a lapse, which can trigger a cognitive-emotional cascade leading to full relapse.

Question 74: The mesolimbic pathway, a critical circuit in the neurobiology of addiction, involves the projection of dopaminergic neurons from the:

Substantia Nigra to the Dorsal Striatum
Ventral Tegmental Area (VTA) to the Nucleus Accumbens (Correct answer)
Prefrontal Cortex to the Basal Ganglia
Amygdala to the Hippocampus

Correct answer: Ventral Tegmental Area (VTA) to the Nucleus Accumbens

The mesolimbic dopamine pathway is central to reward and reinforcement. It consists of dopamine-releasing neurons that originate in the Ventral Tegmental Area (VTA) and project to the Nucleus Accumbens (NAc). Virtually all drugs of abuse increase dopamine levels in the NAc, which reinforces drug-taking behavior.

Question 75: A patient receiving extended-release naltrexone (Vivitrol) injection reports that heroin had no effect when used. This best demonstrates which pharmacological property?

Sustained opioid receptor blockade preventing euphoria (Correct answer)
Negative reinforcement through aversive effects
Competitive inhibition reversible by high-dose opioids
Irreversible enzyme inhibition

Correct answer: Sustained opioid receptor blockade preventing euphoria

Extended-release naltrexone provides continuous opioid receptor blockade for approximately 30 days, preventing opioids from producing euphoria.

Question 76: The concept of 'therapeutic use of self' in addiction nursing most closely relates to which professional responsibility?

Avoiding emotional engagement to prevent burnout
Sharing personal recovery experiences to build rapport with patients
Maintaining objectivity by minimizing personal interaction
Using the nurse-patient relationship as a healing tool while maintaining boundaries (Correct answer)

Correct answer: Using the nurse-patient relationship as a healing tool while maintaining boundaries

Therapeutic use of self means deliberately using one's personality and relationship skills as a clinical tool while maintaining professional boundaries.

Question 77: Which scenario represents an appropriate use of clinical supervision for a CARN?

Reporting a colleague's performance issues to the supervisor
Using supervision sessions to obtain prescriptive authority for addiction medications
Discussing a challenging case with a supervisor to process countertransference reactions (Correct answer)
Seeking peer input to validate a decision already made about patient care

Correct answer: Discussing a challenging case with a supervisor to process countertransference reactions

Clinical supervision provides a structured space to process countertransference and complex clinical reactions that can affect patient care.

Question 78: Why is it important to assess a patient’s substance use history before starting pharmacological treatment?

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

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

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

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 80: 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 81: What is a key factor in delivering effective addiction education to patients?

Tailoring the information to the patient's needs and understanding level (Correct answer)
Using overly technical language to impress the patient
Using generic content that applies to all patients
Overloading the patient with irrelevant information

Correct answer: Tailoring the information to the patient's needs and understanding level

Delivering effective addiction education requires tailoring the information to each patient's unique needs, cultural background, and level of understanding. A personalized approach ensures the content is relevant, comprehensible, and actionable for the individual. This customization increases patient engagement and the likelihood that they will successfully apply learned strategies in their recovery journey.

Question 82: A patient in a methadone maintenance program requests that their treatment information not be shared with their employer. Under 42 CFR Part 2, the nurse should:

Refer the employer to the medical director for information
Obtain written consent from the patient before any disclosure (Correct answer)
Share information if the employer has a legitimate need to know
Disclose only general status without specific details

Correct answer: Obtain written consent from the patient before any disclosure

42 CFR Part 2 requires patient-specific written consent before disclosing substance use disorder treatment records to any third party.

Question 83: In relapse prevention education, the acronym HALT stands for:

High-risk, Avoidant, Lapsed, Triggered
Hungry, Angry, Lonely, Tired (Correct answer)
Healthy, Abstinent, Lucid, Trusting
Hopeful, Accountable, Linked, Therapeutic

Correct answer: Hungry, Angry, Lonely, Tired

HALT (Hungry, Angry, Lonely, Tired) identifies four physical and emotional states that increase vulnerability to cravings and relapse.

Question 84: A patient reports using kratom daily to self-manage opioid cravings. The CARN nurse should recognize that kratom:

Is classified as a Schedule II controlled substance in all US states
Is an FDA-approved herbal supplement for opioid use disorder
Contains alkaloids that act on opioid receptors and can cause dependence and withdrawal (Correct answer)
Has no significant pharmacological activity

Correct answer: Contains alkaloids that act on opioid receptors and can cause dependence and withdrawal

Kratom contains mitragynine and 7-hydroxymitragynine, which bind opioid receptors; regular use can cause opioid-type dependence and withdrawal syndrome.

Question 85: For a pregnant patient with opioid use disorder, which treatment is considered the standard of care?

Clonidine-assisted withdrawal in the third trimester
Methadone or buprenorphine maintenance therapy (Correct answer)
Abrupt opioid detoxification in the second trimester
Naltrexone extended-release injection monthly

Correct answer: Methadone or buprenorphine maintenance therapy

Methadone and buprenorphine maintenance are the evidence-based standards of care for pregnant patients with OUD, reducing fetal risk associated with repeated withdrawal cycles.

Question 86: Which antidepressant class is generally preferred for treating depression co-occurring with alcohol use disorder due to its safety profile and evidence base?

Monoamine oxidase inhibitors (MAOIs)
Tricyclic antidepressants (TCAs)
Benzodiazepines
Selective serotonin reuptake inhibitors (SSRIs) (Correct answer)

Correct answer: Selective serotonin reuptake inhibitors (SSRIs)

SSRIs are preferred for co-occurring depression and alcohol use disorder due to their favorable safety profile, low abuse potential, and evidence of efficacy.

Question 87: 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 88: 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?

Extended Amygdala (Correct answer)
Hippocampus
Basal Ganglia
Prefrontal Cortex

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 89: A nurse is using motivational interviewing during an addiction assessment. Which response best demonstrates the 'reflective listening' technique?

'I'm going to refer you to inpatient treatment today.'
'You should seriously consider stopping your drug use.'
'Have you tried AA or NA before?'
'It sounds like you feel torn between wanting to quit and enjoying the relief substances provide.' (Correct answer)

Correct answer: 'It sounds like you feel torn between wanting to quit and enjoying the relief substances provide.'

Reflective listening involves paraphrasing or reflecting back the patient's feelings and ambivalence without judgment, a core technique in motivational interviewing.

Question 90: Which benzodiazepine property makes diazepam particularly prone to misuse compared to oxazepam?

Diazepam has active metabolites; oxazepam does not
Diazepam has higher protein binding than oxazepam
Diazepam requires hepatic glucuronidation; oxazepam does not
Diazepam has a faster onset of action due to higher lipophilicity (Correct answer)

Correct answer: Diazepam has a faster onset of action due to higher lipophilicity

Diazepam's high lipophilicity allows rapid CNS penetration and faster onset, producing a more intense euphoric effect that increases its misuse potential.

Question 91: 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:

Evidence of well-developed coping skills
A healthy sign of growing self-confidence in recovery
An appropriate goal for someone in late-stage recovery
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 92: A nurse is teaching a patient with cannabis use disorder about withdrawal. Which symptom should be included in the education?

Hallucinations and delirium in the first week
Irritability, sleep disturbances, and decreased appetite beginning within 1-3 days of cessation (Correct answer)
Seizures within the first 24 hours of cessation
Severe hypertension requiring antihypertensive medication

Correct answer: Irritability, sleep disturbances, and decreased appetite beginning within 1-3 days of cessation

Cannabis withdrawal syndrome includes irritability, anxiety, sleep disturbances, and decreased appetite, typically beginning 1-3 days after cessation.

Question 93: When performing a urine drug screen interpretation, a nurse knows that false-positive results for opioids can be caused by which common substance?

Poppy seed consumption (Correct answer)
Quinolone antibiotics
Vitamin C supplementation
Ibuprofen

Correct answer: Poppy seed consumption

Poppy seeds contain morphine and codeine in small amounts and can cause false-positive immunoassay results for opioids.

Question 94: 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?

Foods high in tyramine, such as aged cheeses
Nicotine replacement therapy
Mouthwash containing alcohol (Correct answer)
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 95: Which type of coping skill education is most evidence-based for patients with co-occurring PTSD and substance use disorder?

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

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 96: Which component of the ASI (Addiction Severity Index) evaluates the patient's subjective perception of their problem and motivation for treatment?

Medical status domain
Interviewer severity rating (Correct answer)
Patient rating subscale
Composite score

Correct answer: Interviewer severity rating

The ASI includes an interviewer severity rating that captures the patient's subjective distress and perceived need for treatment in each domain.

Question 97: A patient scores 20 on the AUDIT-C. What does this indicate?

Hazardous or harmful alcohol use
Low-risk drinking
The score is outside the valid range (Correct answer)
Moderate alcohol use

Correct answer: The score is outside the valid range

The AUDIT-C maximum score is 12; a score of 20 is impossible, indicating a scoring or administration error.

Question 98: A nurse uses the Clinical Opiate Withdrawal Scale (COWS). A score of 25 indicates which severity level?

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

Correct answer: Severe withdrawal

On the COWS, a score of 25 falls in the severe withdrawal range (scores ≥25 = severe).

Question 99: 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 has tried to stop using cocaine multiple times but has been unsuccessful.
A patient misses several important family events because they are recovering from the effects of binge drinking.
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 100: Which motivational interviewing technique is MOST effective when a patient with co-occurring disorders expresses ambivalence about treatment?

Setting firm boundaries and ultimatums
Providing detailed psychoeducation about consequences
Confrontation to break through denial
Reflective listening and exploring ambivalence (Correct answer)

Correct answer: Reflective listening and exploring ambivalence

Reflective listening and exploring ambivalence are core MI techniques that help patients with co-occurring disorders move toward change by building intrinsic motivation.

Question 101: 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:

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

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 102: What is an example of a screening tool used in addiction assessment?

CAGE questionnaire for alcohol-related behaviors (Correct answer)
Family history assessment
Physical examination
Blood test for substances

Correct answer: CAGE questionnaire for alcohol-related behaviors

The CAGE questionnaire is a widely recognized and validated screening tool specifically designed to identify potential alcohol-related problems. It consists of four simple questions that help healthcare professionals quickly assess if a patient needs a more in-depth evaluation for alcohol use disorder. Unlike general physical exams or blood tests, CAGE directly targets behavioral patterns indicative of problematic drinking.

Question 103: A patient presents to the ED with agitation, diaphoresis, hyperthermia, and muscle rigidity after combining their prescribed SSRI with illegally obtained MDMA. What condition should the nurse suspect?

Neuroleptic malignant syndrome
Sympathomimetic crisis
Anticholinergic toxidrome
Serotonin syndrome (Correct answer)

Correct answer: Serotonin syndrome

Serotonin syndrome results from excess serotonergic activity and is classically triggered by combining serotonergic agents (SSRI + MDMA), presenting with the triad of agitation, autonomic instability, and neuromuscular abnormalities.

Question 104: Which of the following is a key diagnostic tool in addiction assessment?

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

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 105: A nurse assesses a patient for nicotine dependence using the Fagerström Test. The most critical item predicting dependence severity is:

How much the patient spends on cigarettes weekly
Whether the patient smokes within 30 minutes of waking (Correct answer)
Whether the patient smokes indoors
How many cigarettes the patient smokes per day

Correct answer: Whether the patient smokes within 30 minutes of waking

Time to first cigarette after waking is the strongest predictor of nicotine dependence severity on the Fagerström scale.

Question 106: When a patient threatens to harm a specific, identifiable third party, a nurse's legal duty under Tarasoff principles requires:

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

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 107: A nurse screens an adolescent for substance use. Which tool is specifically designed and validated for this age group?

CAGE
AUDIT
CRAFFT (Correct answer)
DAST-10

Correct answer: CRAFFT

The CRAFFT screening tool is specifically designed and validated for identifying substance use problems in adolescents.

Question 108: A patient with depression and alcohol use disorder achieves sobriety. How long should the nurse wait before reassessing depressive symptoms to distinguish substance-induced depression from independent major depression?

3 months
1 week
2-4 weeks (Correct answer)
6 months

Correct answer: 2-4 weeks

Current guidelines recommend waiting 2-4 weeks of sobriety before reassessing depressive symptoms, as many substance-induced mood symptoms resolve within this timeframe.

Question 109: The ASI (Addiction Severity Index) assesses problem severity across how many life domains?

4
9
7 (Correct answer)
5

Correct answer: 7

The ASI evaluates seven domains: medical, employment/support, alcohol, drug, legal, family/social, and psychiatric status.

Question 110: A nurse is assessing a patient who uses methamphetamine daily. Which psychiatric symptom is most commonly associated with stimulant use disorder?

Severe respiratory depression
Paranoid psychosis (Correct answer)
Opioid-like euphoria
Hypersomnia during intoxication

Correct answer: Paranoid psychosis

Paranoid psychosis, including hallucinations and delusions, is a common psychiatric complication of chronic methamphetamine use.

Question 111: The IntNSA Code of Ethics for Addictions Nursing emphasizes which unique professional obligation compared to general nursing ethics codes?

Recognition of addiction as a chronic brain disorder requiring non-stigmatizing, patient-centered care (Correct answer)
Mandatory peer support group participation for all addiction nursing staff
Prohibition of nurses in personal recovery from working in addiction treatment settings
Greater emphasis on patient autonomy over beneficence in all treatment decisions

Correct answer: Recognition of addiction as a chronic brain disorder requiring non-stigmatizing, patient-centered care

The IntNSA Code emphasizes the disease model of addiction and the obligation to provide non-stigmatizing, evidence-based care that respects patient dignity.

Question 112: Why is buprenorphine used in opioid addiction treatment?

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

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 113: Which education strategy is most effective for improving medication adherence in patients on medications for opioid use disorder (MOUD)?

Pill organizers alone are sufficient for all patients
Providing written instructions without verbal follow-up
Collaborative goal-setting, addressing side effect concerns, and using reminder tools (Correct answer)
Threatening to discontinue treatment if doses are missed

Correct answer: Collaborative goal-setting, addressing side effect concerns, and using reminder tools

Collaborative goal-setting, addressing side effects, and practical reminder tools together support adherence by addressing motivational, informational, and logistical barriers.

Question 114: A nurse is educating a patient about naloxone (Narcan) take-home kits. Which patient statement indicates understanding of when to use it?

I should administer it and then wait 30 minutes before calling 911
I should give it to someone who is unresponsive, has slow or no breathing, and may have taken opioids (Correct answer)
I should use it every time I take opioids to prevent overdose
I should only use it if the person is using heroin, not prescription opioids

Correct answer: I should give it to someone who is unresponsive, has slow or no breathing, and may have taken opioids

Naloxone is indicated for suspected opioid overdose characterized by unresponsiveness, slow/absent breathing, and known or suspected opioid exposure; 911 must also be called.

Question 115: Which finding during an opioid withdrawal assessment using the COWS scale indicates severe withdrawal and warrants aggressive pharmacological management?

COWS score of 36 or above (Correct answer)
COWS score of 13–24
COWS score of 5
COWS score of 2–4

Correct answer: COWS score of 36 or above

A COWS score of 36 or above indicates severe opioid withdrawal requiring immediate and aggressive treatment intervention.

Question 116: Extended-release naltrexone (Vivitrol) is appropriate for a patient who:

Is currently using opioids daily
Is pregnant and seeking opioid use disorder treatment
Has completed opioid detoxification and is opioid-free (Correct answer)
Has acute hepatitis with ALT >10x normal

Correct answer: Has completed opioid detoxification and is opioid-free

Naltrexone must only be initiated after full opioid detoxification to avoid precipitated withdrawal; patients must be opioid-free for 7–10 days before starting.

Question 117: A treatment program for stimulant use disorder provides patients with escalating cash-value vouchers for each consecutive drug-free urine sample. This intervention is a primary example of which therapeutic modality?

Motivational Interviewing (MI)
Contingency Management (CM) (Correct answer)
12-Step Facilitation (TSF)
Cognitive Behavioral Therapy (CBT)

Correct answer: Contingency Management (CM)

Contingency Management is a behavioral therapy based on operant conditioning that provides tangible, positive reinforcement (like vouchers) to reward desired behaviors, such as providing a substance-free urine sample.

Question 118: The ethical principle of veracity in addiction nursing practice requires the nurse to:

Tell patients only what they need to know to remain compliant with treatment
Withhold negative prognosis information to maintain patient hope
Provide truthful information even when it may be difficult for patients to hear (Correct answer)
Share information selectively based on the patient's stage of change

Correct answer: Provide truthful information even when it may be difficult for patients to hear

Veracity obligates nurses to be truthful with patients, which includes honest communication about prognosis, risks, and treatment limitations.

Question 119: A nurse is caring for a neonate born to a mother who used opioids during pregnancy. The infant has a Finnegan Neonatal Abstinence Scoring score of 9. What is the appropriate next step?

Begin pharmacological treatment with morphine or methadone (Correct answer)
Administer naloxone to reverse residual opioid effects
Continue non-pharmacological comfort measures and recheck in 2 hours
Discharge the infant to foster care per hospital policy

Correct answer: Begin pharmacological treatment with morphine or methadone

A Finnegan score of 8 or higher on two consecutive assessments (or ≥ 12 on a single assessment) generally triggers pharmacological treatment.

Question 120: Which educational content is most appropriate when teaching a patient about relapse as part of the chronic disease model of addiction?

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

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 121: Bupropion (Wellbutrin/Zyban) aids smoking cessation through which primary mechanism?

GABA-B agonism reducing reward from nicotine
Inhibition of dopamine and norepinephrine reuptake, reducing nicotine cravings and withdrawal symptoms (Correct answer)
Partial agonism at nicotinic receptors reducing withdrawal
Serotonin reuptake inhibition improving mood during abstinence

Correct answer: Inhibition of dopamine and norepinephrine reuptake, reducing nicotine cravings and withdrawal symptoms

Bupropion inhibits dopamine and norepinephrine reuptake, partially compensating for the dopaminergic deficit during nicotine cessation and reducing cravings.

Question 122: A client who is stable in treatment for Opioid Use Disorder (OUD) with buprenorphine is newly diagnosed with Generalized Anxiety Disorder (GAD). The addictions nurse should anticipate the provider will AVOID prescribing which class of medication due to its high potential for misuse and dangerous synergistic effects?

Hydroxyzine
Selective Serotonin Reuptake Inhibitors (SSRIs)
Benzodiazepines (Correct answer)
Buspirone

Correct answer: Benzodiazepines

Benzodiazepines, when combined with opioids like buprenorphine, significantly increase the risk of life-threatening respiratory depression. They also have a high potential for misuse and dependence, making them a high-risk choice for a client with a pre-existing substance use disorder. SSRIs, buspirone, and hydroxyzine are considered safer, non-addictive alternatives for managing anxiety in this population.

Question 123: 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?

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

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 124: 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.
Providing a gift card for each verified stimulant-free urine drug screen. (Correct answer)
Administering a prescribed medication to reduce cravings and withdrawal symptoms.

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

Diazepam
Chlordiazepoxide
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 126: When a patient with a sedative-hypnotic use disorder requires treatment, the nurse plans for which unique risk compared to other substance use disorders?

Minimal withdrawal symptoms that resolve within 24 hours
Higher risk of psychological dependence with no physical withdrawal
Potential for life-threatening withdrawal requiring medical management (Correct answer)
Withdrawal symptoms that are uncomfortable but never medically dangerous

Correct answer: Potential for life-threatening withdrawal requiring medical management

Sedative-hypnotic withdrawal can cause seizures and delirium, making it potentially fatal and requiring medically supervised management.

Question 127: A patient in a methadone clinic is also prescribed benzodiazepines by an outside psychiatrist. The addiction nurse's ethical duty regarding this information is to:

Ignore it since the psychiatrist is responsible for that prescription
Report the psychiatrist to the licensing board immediately
Inform the patient of the interaction risk and coordinate care with the prescriber (Correct answer)
Discontinue the methadone without consulting the patient

Correct answer: Inform the patient of the interaction risk and coordinate care with the prescriber

The nurse has a duty to educate the patient about potentially dangerous drug interactions and facilitate interprofessional communication to ensure safe care.

Question 128: A patient expresses shame about their addiction during an education session. The most therapeutic nursing response is to:

Redirect the conversation immediately to medication adherence
Agree that making better choices sooner would have been ideal
Remind the patient of their responsibilities to their family
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 129: A nurse is conducting a trauma-informed addiction assessment. Which approach best aligns with trauma-informed care principles?

Documenting trauma history without discussing it with the patient
Asking detailed trauma questions in the first session to complete the intake form
Creating a safe environment, obtaining consent, and allowing the patient to control the pace (Correct answer)
Focusing exclusively on substance use history before addressing trauma

Correct answer: Creating a safe environment, obtaining consent, and allowing the patient to control the pace

Trauma-informed care prioritizes safety, trustworthiness, choice, and empowerment—allowing patients to control the pace and content of trauma disclosure.

Question 130: When assessing a patient using the DAST-10 (Drug Abuse Screening Test), a score of 6 or higher indicates:

A low-risk use pattern
No problem; continue monitoring
Results are inconclusive and the test should be repeated
Substantial drug problems requiring further assessment and intervention (Correct answer)

Correct answer: Substantial drug problems requiring further assessment and intervention

DAST-10 scores of 6–8 indicate substantial drug problems, and scores of 9–10 indicate severe problems, both warranting clinical intervention.

Question 131: A nurse co-facilitating a process group notices that new members are unusually silent. According to Yalom's group therapy principles, which therapeutic factor is MOST impaired by this dynamic?

Catharsis
Universality
Altruism
Interpersonal learning (Correct answer)

Correct answer: Interpersonal learning

Interpersonal learning — gaining insight through feedback and interaction with others — is most impaired when members are silent and not engaging with each other.

Question 132: Which physical finding is most consistent with chronic intravenous drug use during a physical assessment?

Track marks and thrombosed veins (Correct answer)
Hypertension and tachycardia
Jaundice and asterixis
Rhinorrhea and nasal septum perforation

Correct answer: Track marks and thrombosed veins

Track marks (venipuncture scars) and thrombosed or sclerosed veins are characteristic physical findings of chronic IV drug use.

Question 133: When educating a patient with low health literacy about opioid tapering, which communication strategy is most effective?

Use medical terminology to maintain professionalism
Provide a detailed 20-page pamphlet for home review
Delegate all education to the pharmacist
Use the teach-back method with simple, plain language (Correct answer)

Correct answer: Use the teach-back method with simple, plain language

The teach-back method with plain language confirms patient understanding and is the gold standard for low-literacy populations.

Question 134: What role do family members play in supporting addiction recovery?

They prevent the patient from attending therapy sessions
They isolate the patient from other support networks
They increase the patient’s risk of relapse
They provide emotional support and create a stable environment for recovery (Correct answer)

Correct answer: They provide emotional support and create a stable environment for recovery

Family members can play a vital role in addiction recovery by offering crucial emotional support and helping to establish a stable, drug-free home environment. Their understanding, encouragement, and participation in family therapy can significantly reduce stress and improve communication. This support reinforces positive behaviors and strengthens the patient's overall recovery journey.

Question 135: In integrated dual diagnosis treatment (IDDT), the primary advantage over sequential treatment is:

It is less expensive and requires fewer providers
Patients must achieve sobriety before addressing mental health needs
Both disorders are addressed simultaneously by the same treatment team (Correct answer)
Mental health treatment is prioritized over addiction treatment

Correct answer: Both disorders are addressed simultaneously by the same treatment team

IDDT ensures that both disorders are treated concurrently by the same team, eliminating gaps and inconsistencies that occur with sequential approaches.

Question 136: 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 patches contain a reservoir of drug designed for 72-hour release that can be rapidly absorbed if misused (Correct answer)
Fentanyl undergoes extensive first-pass metabolism when swallowed
Fentanyl has a very long half-life of 48 hours

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 137: Which protective factor is MOST strongly associated with sustained long-term recovery outcomes?

Complete avoidance of all social situations involving others
Financial stability as the primary determinant of recovery success
Having completed multiple episodes of inpatient treatment
Strong social support networks and meaningful community connections (Correct answer)

Correct answer: Strong social support networks and meaningful community connections

Strong social support networks and meaningful community connections are among the most robust and consistently replicated predictors of long-term recovery across diverse populations.

Question 138: In Prochaska's Transtheoretical Model, which stage is characterized by the patient making specific plans to change behavior within the next 30 days?

Contemplation
Preparation (Correct answer)
Action
Maintenance

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 139: A CARN documents inaccurate information in a patient's chart at a supervisor's request to justify a treatment decision that was made incorrectly. This action constitutes:

Acceptable practice when ordered by a supervisor
Falsification of medical records, which is both illegal and unethical (Correct answer)
A minor documentation variance that does not affect patient care
A protected internal quality improvement action

Correct answer: Falsification of medical records, which is both illegal and unethical

Falsifying medical records is illegal regardless of who requests it and violates the nurse's ethical obligation to maintain accurate documentation.

Question 140: In the context of addiction assessment, 'telescoping' refers to which phenomenon?

Women progressing more rapidly from first use to dependence than men (Correct answer)
Reduction in withdrawal severity with each detox episode
Gradual dose escalation over time
Alternating periods of use and abstinence

Correct answer: Women progressing more rapidly from first use to dependence than men

Telescoping describes the accelerated progression from initiation of substance use to dependence observed in women compared to men.

Question 141: The CARN nurse is reviewing medications for a patient with co-occurring opioid use disorder and major depressive disorder on buprenorphine. Which antidepressant combination requires the most caution due to CYP3A4 interactions?

Fluoxetine and fluvoxamine (Correct answer)
Mirtazapine
Bupropion
Sertraline

Correct answer: Fluoxetine and fluvoxamine

Fluoxetine and fluvoxamine significantly inhibit CYP3A4 and CYP2D6, potentially increasing buprenorphine plasma levels and requiring dose monitoring.

Question 142: Which finding on a comprehensive liver panel would most specifically suggest alcoholic hepatitis in a patient with alcohol use disorder?

Decreased alkaline phosphatase
Isolated elevation of ALT only
AST:ALT ratio greater than 2:1 (Correct answer)
Normal bilirubin with elevated albumin

Correct answer: AST:ALT ratio greater than 2:1

An AST:ALT ratio greater than 2:1 is a classic laboratory pattern associated with alcoholic hepatitis.

Question 143: Buprenorphine's 'ceiling effect' on respiratory depression is primarily due to its action as a:

Full antagonist at kappa receptors
Full opioid agonist at mu receptors
Partial agonist at mu receptors (Correct answer)
Pure antagonist at all opioid receptors

Correct answer: Partial agonist at mu receptors

Buprenorphine's partial agonist activity at mu-opioid receptors creates a ceiling effect, reducing the risk of fatal respiratory depression compared to full agonists.

Question 144: During assessment, a patient reports using heroin but denies needing help. According to Prochaska's stages of change model, which stage best describes this patient?

Contemplation
Preparation
Precontemplation (Correct answer)
Maintenance

Correct answer: Precontemplation

A patient who uses substances and does not recognize a problem or need for change is in the precontemplation stage.

Question 145: 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?

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

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 146: A patient with co-occurring PTSD and alcohol use disorder is beginning treatment. Which integrated treatment approach is recommended over sequential treatment?

Treating alcohol use disorder first until stable, then starting PTSD therapy
Referring to separate specialists who communicate quarterly
Providing simultaneous treatment for both conditions in a coordinated plan (Correct answer)
Treating PTSD first, then initiating alcohol use disorder treatment after 6 months of sobriety

Correct answer: Providing simultaneous treatment for both conditions in a coordinated plan

Integrated treatment addressing both PTSD and substance use disorder simultaneously produces better outcomes than sequential or parallel non-coordinated approaches.

Question 147: 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?

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

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

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

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 149: What is the role of cognitive-behavioral therapy (CBT) in addiction treatment?

To increase the patient’s dependence on substances
To help patients change negative thought patterns and behaviors associated with addiction (Correct answer)
To isolate the patient from other treatment modalities
To focus only on physical withdrawal symptoms

Correct answer: To help patients change negative thought patterns and behaviors associated with addiction

Cognitive-behavioral therapy (CBT) is a cornerstone of addiction treatment, focusing on identifying and changing maladaptive thought patterns and behaviors that contribute to substance use. It teaches patients to recognize triggers, challenge distorted thinking, and develop healthier coping mechanisms. CBT empowers individuals to manage cravings and avoid relapse by altering their responses to internal and external cues.

Question 150: A patient with cocaine use disorder asks about FDA-approved pharmacotherapy. Which statement is most accurate?

Modafinil is FDA-approved and highly effective for cocaine use disorder
Naltrexone is FDA-approved for cocaine use disorder
There are currently no FDA-approved medications specifically for cocaine use disorder (Correct answer)
Disulfiram is FDA-approved as first-line treatment for cocaine use disorder

Correct answer: There are currently no FDA-approved medications specifically for cocaine use disorder

As of 2025, no medications are FDA-approved specifically for cocaine use disorder, though several (topiramate, disulfiram) show limited evidence in research settings.

Question 151: A client with a co-occurring diagnosis of Post-Traumatic Stress Disorder (PTSD) and Opioid Use Disorder (OUD) is beginning an integrated treatment program. The nurse understands that the primary rationale for an integrated approach is that:

Pharmacotherapy for OUD is contraindicated in patients with PTSD.
Separate treatment programs are more specialized and therefore more effective.
Treating the substance use disorder first will resolve the PTSD symptoms.
PTSD symptoms are often a primary driver for substance use and relapse. (Correct answer)

Correct answer: PTSD symptoms are often a primary driver for substance use and relapse.

Research and clinical practice show a strong link between PTSD and SUD, with many individuals using substances to self-medicate or cope with trauma-related symptoms like anxiety, hyperarousal, and intrusive memories. An integrated treatment model addresses both disorders concurrently, recognizing that untreated PTSD symptoms are a significant risk factor for substance use relapse. Treating them separately or sequentially is less effective.
