A client with known coronary artery disease reports intermittent chest pain, usually on exertion. When teaching the client about nitroglycerin administration, which instruction should the nurse provide? “You may take a sublingual nitroglycerin tablet every 30 minutes, if needed. You may take as many as four doses.” “Replace leftover sublingual nitroglycerin tablets every 9 months to make sure your pills are fresh.” “Be sure to take safety precautions because nitroglycerin may cause dizziness when you stand up.” “A burning sensation after administration indicates that the nitroglycerin tablets are potent.”
