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

A. Absence of xerostomia: Xerostomia (dry mouth) is a possible side effect of bethanechol but does not indicate the medication’s effectiveness in relieving urinary retention. B. No terminal urinary dribbling: While terminal dribbling can be a symptom of urinary retention, its absence alone is not the most reliable indicator that bethanechol is effectively improving bladder emptying. C. Denies stress incontinence: Stress incontinence is related to increased abdominal pressure and weak pelvic muscles, which is different from urinary retention. Denial of stress incontinence does not confirm the medication’s efficacy. D. Urinary output equals intake: When urinary output matches intake, it indicates effective bladder emptying and resolution of urinary retention. This is the most direct and objective measure that bethanechol is working as intended.
