The question bank is the fastest way to start, but PMHNP Helper also includes board-review planning, student resources, and plain-English guidance for psychiatric nurse practitioner students who are still learning the exam landscape.
A 52-year-old male with a 20-year history of alcohol use disorder is admitted to the medical unit after presenting with tremor, diaphoresis, and anxiety 18 hours after his last drink. His CIWA-Ar score is 22. On assessment, he demonstrates coarse tremor with arms extended, moderate diaphoresis, reports visual disturbances described as 'the walls are moving,' and exhibits marked anxiety and agitation. Vital signs reveal heart rate 108 bpm, blood pressure 168/102 mmHg, and temperature 37.8°C. He had a prior alcohol withdrawal seizure 3 years ago. The PMHNP is determining the severity classification and monitoring frequency. Which interpretation of the CIWA-Ar score and clinical presentation best guides the assessment and monitoring plan?
Explanation
The CIWA-Ar score categorizes alcohol withdrawal severity as mild (less than 10), moderate (10-19), or severe (20 or above). A score of 22 indicates severe withdrawal requiring frequent monitoring every 1-2 hours. Clinical risk factors including prior withdrawal seizures must be integrated alongside the CIWA-Ar score, as prior seizures independently increase risk for recurrent seizures and delirium tremens through the kindling mechanism. The temporal window of 18 hours post-last-drink places the patient within the peak seizure risk period.
Key Takeaway
A CIWA-Ar score of 20 or above indicates severe alcohol withdrawal, and prior withdrawal seizures independently elevate risk for recurrent seizures and delirium tremens — comprehensive assessment integrates the CIWA-Ar score with clinical risk factors rather than relying on the numerical score alone.
