The nurse is caring for a resident in a long-term care facility with a history of an anxiety disorder. The client is receiving oral lorazepam 2 mg t.i.d. What assessment should the nurse prioritize?

A. Suicidal ideation: While monitoring for suicidal thoughts is important in clients with anxiety disorders, lorazepam is primarily a CNS depressant, not an antidepressant, and LOC changes are more immediate safety concerns. B. Level of consciousness: Lorazepam is a benzodiazepine that can cause sedation, dizziness, and CNS depression. Monitoring LOC helps detect oversedation or potential respiratory depression early, especially with frequent dosing. C. Sleep quality: Although lorazepam may affect sleep, it is not a safety priority. Sleep quality is more of a long-term wellness concern and doesn't outweigh the need to monitor for acute CNS effects. D. Mucous membrane integrity: This is not a priority concern with lorazepam unless there are concurrent medications or dehydration risks. It does not address the drug’s primary adverse effects.
