A client with a history of angina reports the onset of chest pain. The nurse determines that the heart rate is 104 beats/minute and the blood pressure is 138/86 mm Hg. A transdermal nitroglycerin patch was applied 30 minutes ago to the right upper chest. Which action should the nurse take?

Leave the patch in place and administer a PRN dose of sublingual nitroglycerin.

Reassure the client that the patch will begin to take effect within a few minutes.

Withhold further doses of nitroglycerin until contacting the healthcare provider.

Obtain another transdermal patch and position it on the patient's left upper chest.
