A nurse is providing teaching to a client who has a new prescription for lorazepam. Which of the following statements by the client indicates an understanding of the teaching?

Rationale: A. Lorazepam, a benzodiazepine, is not associated with weight loss. Common effects are related to central nervous system (CNS) depression such as sedation, not metabolic changes leading to weight reduction. B. Lorazepam enhances the effect of gamma-aminobutyric acid (GABA), producing CNS depression. The most common and expected adverse effect is drowsiness or sedation. Clients should be taught to avoid driving, operating heavy machinery, or engaging in activities requiring alertness until they know how the medication affects them. C. This is not typical of lorazepam. A metallic taste is more commonly associated with medications such as metronidazole or certain chemotherapy agents, not benzodiazepines. D. Lorazepam does not affect potassium levels. Electrolyte disturbances are not a known adverse effect of benzodiazepines.
