A client who experienced a myocardial infarction is taught about nitroglycerin tablets. Which statement indicates understanding?

The statement indicating understanding of how to use nitroglycerin tablets is the one about taking two tablets 15 minutes apart and contacting a healthcare provider if there is no relief. This approach aligns with established guidelines for the use of nitroglycerin in the event of chest pain due to angina or myocardial infarction.

Nitroglycerin is a vasodilator used to relieve chest pain. The correct protocol is to take one tablet at the onset of chest pain and wait for about five minutes. If the pain persists, it is appropriate to take a second tablet. If after 15 minutes there’s no relief, contacting a healthcare provider is crucial, as it may indicate a more serious cardiac event that requires immediate intervention.

This understanding emphasizes the importance of monitoring symptoms and being proactive about seeking help when necessary. It's critical for patients to know not only how and when to use their medication but also when to seek additional care, as complications can arise quickly in the setting of a myocardial infarction.
