Final answer:
The nurse should expect the client to complain about potential side effects such as drowsiness, slowness in response to stimuli, and changes in mood.
Step-by-step explanation:
The nurse should expect the client to complain about potential side effects such as drowsiness, slowness in response to stimuli, and changes in mood. Phenelzine sulfate (Nardil) is a monoamine oxidase inhibitor (MAOI) used for the treatment of depression. MAOIs can cause sedation and changes in emotional states. It is important for the nurse to educate the client about these potential side effects and to monitor their response to the medication.
