A nurse is reinforcing teaching with a client who has chronic stable angina and a new prescription for sublingual nitroglycerin. Which of the following instructions should the nurse include in the teaching?
"Take the medication with a sip of water."
"Take up to four tablets in 15 minutes."
"Chew each tablet completely before swallowing.
"Take one tablet before a strenuous activity."
The Correct Answer is D
A. Nitroglycerin is meant to be absorbed under the tongue, and water is not necessary.
B. The client should take up to three doses 5 minutes apart and seek emergency medical attention if pain persists. The maximum number of tablets that should be taken in 15 minutes is 3 and not 4 since this could cause severe hypotension and headache.
C. Nitroglycerin tablets are meant to be dissolved under the tongue, not chewed or swallowed.
D. Sublingual nitroglycerin is used to prevent angina attacks by dilating the coronary arteries and increasing blood flow to the heart. The client should take one tablet for 5 to 10 minutes before engaging in an activity that might trigger angina, such as exercise, stress, or cold exposure.
