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 72-year-old retired engineer is referred to the psychiatric clinic by his primary care provider after routine labs revealed an elevated GGT and MCV. His wife accompanied him and privately reports that he has been drinking increasing amounts of wine over the past two years since his retirement, currently consuming a bottle of wine most evenings. He minimizes his drinking, stating it helps him relax and sleep. He has a history of hypertension managed with amlodipine and reports occasional falls, the most recent resulting in a bruised rib three weeks ago. His PHQ-9 score is 8, suggesting mild depression. He takes no psychotropic medications. On cognitive screening, his MoCA score is 25. He does not believe he has a drinking problem and is reluctant to discuss his alcohol use. The PMHNP needs to determine the most appropriate approach.
Explanation
Substance use disorders in older adults require age-sensitive screening, assessment, and treatment approaches. Geriatric-specific screening tools such as the SMAST-G are designed to capture patterns of alcohol misuse that are more common in older adults, such as drinking to manage retirement, bereavement, or medical symptoms. Motivational interviewing is essential for engaging ambivalent patients and is more effective than confrontational approaches. Older adults are more susceptible to alcohol's effects due to decreased body water, reduced hepatic metabolism, and increased CNS sensitivity, meaning that lower quantities can cause significant impairment. The NIAAA recommends that adults 65 and older consume no more than one standard drink per day. A comprehensive assessment should include fall risk evaluation, cognitive screening, depression assessment, and review of all medications for alcohol interactions.
Key Takeaway
Geriatric alcohol use disorder assessment requires age-specific screening tools, motivational interviewing for engagement, education about age-related physiological vulnerability to alcohol, and comprehensive evaluation of fall risk, cognition, mood, and medication interactions.
