A nurse discovers that a client has been administered a higher dose of oxybutynin than the prescription indicates. The nurse should assess the client for which of the following adverse effects?
Correct answer
D
Rationale
Rationale for Correct Answer (D - Bradycardia): Excess oxybutynin can lead to anticholinergic effects, including decreased heart rate (bradycardia). This is due to the drug's action on muscarinic receptors in the heart. Assessing for bradycardia is crucial as it can indicate toxicity.
Summary of Incorrect Choices:
A: Increased salivation - Oxybutynin is an anticholinergic drug that typically causes dry mouth, not increased salivation.
B: Hyperthermia - Oxybutynin toxicity does not commonly lead to hyperthermia.
C: Urinary incontinence - Oxybutynin is used to treat urinary incontinence, so excess dose would not cause this adverse effect.
E, F, G: No further choices provided.
