单项选择题
A client has been prescribed 75 mg of amitriptyline (Elavil) at bedtime and 15 mg of phenelzine (Nardil) three times per day. Which nursing action takes priority ？（）
A．Teaching the client about the adverse effects.
B．Calling the physician and questioning the order.
C．Instituting dietary restrictions.
D．Taking baseline vital signs.
答案
参考答案：B
解析：
Administering amitriptyline (a tricyclic antidepressant) and phenelzine (a monoamine oxidase [MAO] inhibitor) together could cause hypertension, tachycardia, or a potentially fatal reaction; the nurse should call the physician to check the order. The other options are important nursing actions, but they don't take priority over calling the physician.
