CARN Managing Co-Occurring Disorders 2 — Questions and Answers
Question 1: A patient with bipolar disorder and alcohol use disorder is stabilized on lithium. Which intervention is most critical regarding alcohol use and lithium therapy?
- Encourage moderate alcohol use to reduce social anxiety
- Educate that alcohol can lower lithium levels and trigger manic episodes (Correct answer)
- Monitor lithium levels only during depressive phases
- Discontinue lithium if the patient relapses on alcohol
Correct answer: Educate that alcohol can lower lithium levels and trigger manic episodes
Alcohol can interfere with lithium metabolism and trigger mood episodes, so patient education on this interaction is essential.
Question 2: Which screening tool is specifically designed to identify co-occurring mental health disorders in patients presenting with substance use disorders?
- AUDIT-C
- DAST-10
- MINI International Neuropsychiatric Interview (MINI) (Correct answer)
- PHQ-2
Correct answer: MINI International Neuropsychiatric Interview (MINI)
The MINI is a structured diagnostic interview designed to assess multiple psychiatric disorders, making it appropriate for co-occurring disorder screening.
Question 3: A patient in early recovery from opioid use disorder begins reporting panic attacks. The CARN should first:
- Assume symptoms are opioid withdrawal and monitor without intervention
- Prescribe benzodiazepines to address the panic disorder
- Conduct a thorough psychiatric assessment to differentiate withdrawal from panic disorder (Correct answer)
- Refer immediately to psychiatry and withhold all medications
Correct answer: Conduct a thorough psychiatric assessment to differentiate withdrawal from panic disorder
Differentiating between substance withdrawal symptoms and a co-occurring anxiety disorder requires comprehensive psychiatric assessment before initiating treatment.
Question 4: The concept of 'parallel treatment' for co-occurring disorders means:
- Treating addiction and mental health simultaneously in separate programs without coordination (Correct answer)
- Using two medications simultaneously for the same diagnosis
- Addressing both disorders in an integrated manner within one treatment episode
- Alternating treatment focus between addiction and mental illness each session
Correct answer: Treating addiction and mental health simultaneously in separate programs without coordination
Parallel treatment involves separate programs addressing addiction and mental health independently, which is less effective than integrated treatment.
Question 5: A patient with schizophrenia and cannabis use disorder states they use cannabis to 'calm the voices.' This pattern is best described as:
- Recreational drug use unrelated to mental illness
- Self-medication to manage psychotic symptoms (Correct answer)
- A sign of medication non-adherence only
- Malingering to obtain psychiatric care
Correct answer: Self-medication to manage psychotic symptoms
Using substances to manage psychiatric symptoms is a common self-medication pattern seen in patients with co-occurring psychotic and substance use disorders.
Question 6: Which factor most significantly complicates the diagnosis of depression in a patient actively using cocaine?
- Cocaine has no effect on mood or neurochemistry
- Cocaine withdrawal mimics depressive symptoms, making diagnosis unreliable during active use (Correct answer)
- Depression is always secondary to cocaine use and resolves with abstinence
- Patients with cocaine use disorder cannot experience true depression
Correct answer: Cocaine withdrawal mimics depressive symptoms, making diagnosis unreliable during active use
Cocaine withdrawal produces depressive symptoms that overlap with major depressive disorder, requiring a period of abstinence before accurate diagnosis.
Question 7: Motivational Interviewing (MI) is considered an evidence-based approach for co-occurring disorders primarily because it:
- Confronts denial aggressively to force behavior change
- Addresses ambivalence about change without triggering defensiveness (Correct answer)
- Focuses exclusively on substance use without addressing mental health
- Requires patients to commit to abstinence before beginning therapy
Correct answer: Addresses ambivalence about change without triggering defensiveness
MI's non-confrontational, empathic style is particularly effective with co-occurring disorders because it addresses ambivalence without increasing resistance.
