Question 1
Emergency department assessment after a marked reduction in daily alcohol intake shows a CIWA-Ar score of 6, intact orientation, and a blood alcohol concentration of 0.11 g/dL. The patient has had withdrawal seizures during two previous attempts to stop drinking. Which conclusion is warranted before choosing a withdrawal-management setting?
Show answer & explanation
Correct answer: A - Current symptoms are mild, but the seizure history increases the risk of complicated withdrawal.
Question 2
The current depressive symptoms began during a period of heavy methamphetamine use and have continued through three weeks without use. The APRN is distinguishing an independent depressive disorder from a substance-induced condition. Which additional history would carry the greatest diagnostic weight?
Show answer & explanation
Correct answer: B - Comparable depressive episodes were documented before methamphetamine use and during prolonged nonuse.
Question 3
For the third time, a 17-year-old who uses cannabis daily presents with episodes of intense vomiting and abdominal discomfort. Hot showers provide temporary relief.

Show answer & explanation
Correct answer: B - Acamprosate 333 mg orally three times daily.

Show answer & explanation
Correct answer: D - Continue the patch and revise the plan for breakthrough cravings.
Question 8
During overdose-response teaching, a patient's sister asks, "I heard naloxone does not work on xylazine. Should I still use it if my brother becomes unresponsive and is barely breathing after using fentanyl?" Which response accurately explains naloxone's role?
