Because antianxiety agents such as chlordiazepoxide (Librium) can potentiate the effects of other drugs, the nurse should incorporate which of the following instructions in her teaching plan（）
A. Avoid mixing antianxiety agents with alcohol or other central nervous system (CNS) depressants.
B. Avoid taking antianxiety agents at bedtime.
C. Avoid taking antianxiety agents on an empty stomach.
D. Avoid consuming aged cheese when taking antianxiety agents.
参考答案：A
解析：
Potentiating effect refers to a drug’s ability to increase the potency of another drug if taken together. Therefore, the client should be instructed to avoid alcohol while taking Librium because it potentiates the drug’s CNS depressant effect. Taken at bedtime, this drug will induce sleep. Librium comes in capsule form and usually can be taken with water. Aged cheese is restricted with monoamine oxidase inhibitors, not Librium.
