A nurse is providing teaching for a client who has a new prescription for alprazolam to treat insomnia. Which of the following instructions should the nurse include?

A. Taking alprazolam with a high-fat meal can delay absorption, which is not recommended unless specifically directed. B. Alprazolam is a benzodiazepine and should be used short-term and only as needed for insomnia due to the risk of dependence and tolerance—not routinely every night. C. Peripheral edema is not a common side effect of alprazolam. D. Alprazolam can cause sedation, dizziness, and impaired coordination, so clients should avoid activities requiring alertness, such as driving or operating machinery.
