Final answer:
The nurse should question the order with the physician.
Step-by-step explanation:
The nurse should question the order with the physician when a tricyclic antidepressant is prescribed for a client who has suffered an acute myocardial infarction (MI) within the past 6 months. Tricyclic antidepressants have several side effects that may pose risks for the client with a recent MI, such as lowering blood pressure and increasing anxiety. It is important for the nurse to communicate concerns and gather more information from the physician to ensure the safety of the client.
