What is the highest priority nursing diagnosis for a client with a history of urinary urgency who is taking oxybutynin (Ditropan)?

A. Risk for impaired urinary elimination: Oxybutynin is used to treat urinary urgency, so it is unlikely to impair urinary elimination and may even improve it. B. Risk for alteration in body image: There is no direct association between oxybutynin use and body image concerns. C. Risk for alteration in bowel elimination: Oxybutynin can cause constipation, but this is not the highest priority compared to dry mouth. D. Risk for altered comfort: dry mouth: Dry mouth is a common and bothersome side effect of oxybutynin, making comfort the highest priority concern.
