FREE CARN Co-Occurring Disorders Questions and Answers

Question 1

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

Accepted Answer

Ensure the safety of the patient and the clinical environment.

Answer

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

Question 2

Which of the following statements best defines the 'integrated treatment' model, which is considered the gold standard for co-occurring disorders?

Accepted Answer

Services for both the mental health and substance use disorders are provided concurrently by the same team in the same location.

Answer

Integrated treatment is an evidence-based approach where a single team of providers works together to address both mental health and substance use disorders at the same time and in the same setting. This model contrasts with sequential treatment (treating one disorder then the other) and parallel treatment (separate providers treating the disorders simultaneously), which can lead to fragmented care.

Question 3

A patient with a history of generalized anxiety disorder (GAD) and cocaine use disorder reports experiencing persistent anxiety, insomnia, and restlessness. To differentiate between GAD symptoms and cocaine withdrawal, which assessment question is most critical for the nurse to ask?

Accepted Answer

"Can you describe the timeline of when you last used cocaine and when these specific symptoms began?"

Answer

Differentiating between a primary anxiety disorder and a substance-induced anxiety disorder requires a careful assessment of the temporal relationship between substance use and symptom onset. Symptoms that appear during or shortly after intoxication or withdrawal and then remit with abstinence are more likely to be substance-induced.

Question 4

When treating a patient with co-occurring Post-Traumatic Stress Disorder (PTSD) and an Alcohol Use Disorder (AUD), which class of medication should be avoided or used with extreme caution for managing anxiety symptoms due to its high potential for misuse?

Accepted Answer

Benzodiazepines

Answer

Benzodiazepines, while effective for short-term anxiety, carry a high risk of tolerance, dependence, and misuse. This risk is significantly elevated in individuals with a history of a substance use disorder, making them a poor choice for ongoing anxiety management in this population. There is mounting evidence of harms associated with chronic benzodiazepine use in patients with PTSD, particularly those who also have an SUD.

Question 5

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?

Accepted Answer

Emotional dysregulation, impulsivity, and self-harm behaviors.

Answer

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.
