Myocardial Infarction (MI) and Angina Pectoris ( 41 Questions)

A client with angina pectoris is prescribed sublingual nitroglycerin tablets. What instructions should the nurse provide about taking nitroglycerin?


Correct Answer: A

A) This choice is correct. Sublingual nitroglycerin tablets are designed to be placed under the tongue at the onset of chest pain (angina) for rapid absorption into the bloodstream. The client should not swallow the tablet but rather allow it to dissolve and be absorbed through the mucous membranes under the tongue.

B) This choice is incorrect because sublingual nitroglycerin should not be taken with a glass of water. It is intended for sublingual use and should not be swallowed whole.

C) This choice is incorrect because crushing the nitroglycerin tablet or mixing it with food can alter its effectiveness. Sublingual nitroglycerin is formulated for rapid absorption when placed under the tongue.

D) This choice is incorrect because while keeping the tablets in their original bottle and away from moisture and heat is important for medication storage, it is not directly related to the administration of nitroglycerin. The client should be instructed on proper sublingual administration for immediate chest pain relief.
