Which assessment finding indicates to the nurse that the prescription bethanechol is effective for a client diagnosed with urinary retention?

A. Absence of xerostomia: Bethanechol, a cholinergic agonist, can stimulate salivary secretions and reduce dry mouth (xerostomia), but its primary therapeutic use in urinary retention focuses on improving bladder emptying rather than treating oral dryness. Thus, this is not the best indicator of its effectiveness for urinary issues. B. Denies stress incontinence: Stress incontinence is unrelated to the mechanism of bethanechol, which promotes bladder contraction to facilitate complete emptying. Denying stress incontinence does not necessarily confirm that urinary retention has been resolved. C. Urinary output equals intake: Bethanechol stimulates the detrusor muscle of the bladder, enhancing its contraction and promoting urination. When urinary output matches intake, it indicates that the bladder is emptying properly, reflecting the medication’s intended therapeutic effect in managing urinary retention. D. No terminal urinary dribbling: Absence of dribbling may suggest better bladder control, but it does not directly confirm the resolution of urinary retention. Complete and regular bladder emptying, indicated by output equaling intake, is a more accurate measure of effective treatment.
