What statement by a client indicates a need for further teaching about nitroglycerin for angina?

The statement about having a prescription plan that allows for bulk purchasing of nitroglycerin indicates a misunderstanding of how this medication should be stored and utilized. Nitroglycerin is a medication that has a limited shelf life and is highly sensitive to environmental factors such as light, heat, and moisture. If a client is purchasing it in bulk, there is a risk that they could end up with expired medication or pills that have been compromised if they are not properly stored.

It's crucial for patients to understand that nitroglycerin should be used as needed for acute angina attacks rather than in large quantities stored for long periods. Each individual dose is intended to be used when symptoms arise, and maintaining a supply that is fresh and within the expiration date is vital to ensure effectiveness.

The other responses, while they demonstrate varying levels of understanding about nitroglycerin, do not indicate a fundamental misunderstanding of its use and storage like the bulk purchasing statement does. Storing the medication properly, planning for emergency care, and ensuring the container is sealed are all appropriate and align with safe medication practices.
