A nurse is caring for a client who is exhibiting a depressed mood one week before the start of their menstrual cycle. The nurse should identify that the client is exhibiting manifestations consistent with which of the following disorders?

A. Educating the patient on the surgical process. Preoperative education is important, but ensuring that all essential preoperative requirements are met takes precedence.

B. Ensuring the patient's preoperative checklist is complete. The preoperative checklist ensures that all necessary steps (e.g., consent, lab results, NPO status) are completed before surgery. Missing an essential step could delay or complicate the procedure.

C. Answering all questions for the patient about surgery. Answering questions is important but is not the priority over ensuring surgical readiness.

D. Admitting the patient to the facility. While admission is necessary, it does not take precedence over ensuring all preoperative preparations are complete.

A. Diarrhea: TCAs cause anticholinergic effects, which more commonly lead to constipation rather than diarrhea.

B. Weight gain/loss: Weight gain is a common side effect of TCAs, though some clients may experience weight loss.

C. Bradycardia: TCAs are more likely to cause tachycardia, arrhythmias, and orthostatic hypotension, not bradycardia.

D. Sexual dysfunction: TCAs can cause sexual dysfunction, including decreased libido, erectile dysfunction, and anorgasmia.
