Which client statement is evidence of the etiology of major depressive disorder from a genetic perspective?

A. Skin breakdown: This is a medical problem or symptom, but it is not a structured nursing diagnosis.

B. Elevated blood pressure: This is a clinical finding rather than a nursing diagnosis.

C. Anxiety: While anxiety is a medical condition, a complete nursing diagnosis should describe the specific effects on the patient, such as "Anxiety related to hospitalization as evidenced by restlessness and increased heart rate."

D. Ineffective breathing pattern: This is a standardized nursing diagnosis as defined by NANDA (North American Nursing Diagnosis Association). It refers to altered respiratory function that nurses can assess and manage.

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.
