The nurse has provided discharge teaching to a client prescribed Nitroglycerin SL. Which statement, made by the client. indicates that the teaching has been effective? "I will:

A. "I will remove the tablets from the bottle and keep in a plastic bag in my handbag." This statement is incorrect because nitroglycerin tablets should be kept in their original amber bottle to protect them from light and moisture. Storing them in a plastic bag can compromise their effectiveness. B. "I will obtain a new prescription every two months so it doesn't expire." While it is important to replace expired medication, nitroglycerin tablets typically have a shelf life of 6 months to 1 year, depending on the formulation. The client should be educated on checking expiration dates rather than just obtaining a new prescription regularly. C. "I will call 911 if I get chest pain that doesn't go away after taking one tablet." This statement indicates understanding of the importance of seeking emergency help if chest pain persists after taking nitroglycerin, as it may signify a more serious condition requiring immediate medical attention. D. "I will leave my bottle of nitroglycerin at home in the medicine cabinet." This is inappropriate because nitroglycerin should be easily accessible, ideally kept with the client at all times, especially when they might experience chest pain.
