A client diagnosed with depression is receiving imipramine 200 mg at bedtime. Which assessment finding should prompt the nurse to consider potentially hazardous side effects of this drug?

Choice A reason: Nasal congestion may occur but is not considered a serious or hazardous side effect of imipramine. It does not typically require urgent intervention. Choice B reason: Urinary retention is a potentially dangerous anticholinergic side effect of tricyclic antidepressants like imipramine. It can lead to bladder distension, infection, or renal complications and requires prompt evaluation. Choice C reason: Dry mouth is a common and expected anticholinergic side effect. While uncomfortable, it is not typically hazardous unless it leads to complications like dental decay or oral infections. Choice D reason: Diarrhea is not a typical side effect of imipramine. In fact, constipation is more common due to its anticholinergic properties.
