A nurse is caring for a client who has a new prescription for a nitroglycerin transdermal patch. Which of the following actions should the nurse take?

A. Take the patch off prior to bathing the client: It is unnecessary to remove the patch before bathing. The patch is waterproof and designed to stay on during such activities. B. Monitor for hypertension after application of the patch: Hypotension, not hypertension, is a potential side effect of nitroglycerin due to vasodilation. Monitoring for hypotension is essential. C. Rotate the application sites of the patch: Rotating application sites prevents skin irritation and ensures proper absorption of the medication. D. Remove the patch every 24 hr: Nitroglycerin patches are typically removed for 10-12 hours each day to prevent tolerance but not necessarily at 24-hour intervals.
