When providing patient education about nitroglycerin to the patient, what would the nurse include in the teaching plan about a nitroglycerin patch?
A) "It only has to be administered once a week."
B) "It is more effective than tablets in treating angina."
C) "It has a longer duration of action."
D) "It is faster acting than the tablets."
C
Feedback:
Transdermal nitroglycerin has a long 24-hour duration of action compared with the sublingual form that lasts 30 to 60 minutes or oral tablets that last 8 to 12 hours. Transdermal patches are neither more nor less effective, but rather it is the speed of onset and duration of action that differ.
