A client with anxiety is beginning treatment with lorazepam (Ativan). It is most important for the nurse to assess the client's:

Choice A reason: Assessing coping mechanisms is important but not the priority when initiating lorazepam. The immediate concern is safety related to drug interactions. Choice B reason: Alcohol use must be assessed first because combining lorazepam with alcohol can cause severe respiratory depression, sedation, and increased risk of overdose. This is the most critical safety assessment. Choice C reason: Motivation for treatment is relevant for long-term adherence but not the most urgent concern when starting benzodiazepines. Choice D reason: Family and social support are important for overall treatment success but are secondary to immediate safety concerns regarding alcohol use.
