Correct Answer: D

Rationale: The correct nursing instruction is D: Take 1 tablet of nitroglycerin and call 911 or go to the emergency department if chest pain is not relieved in 5 minutes, and repeat medication for a total of 3 tablets at 5-minute intervals. This instruction is correct because nitroglycerin is a fast-acting medication that helps to dilate blood vessels, improving blood flow to the heart and reducing chest pain. In cases of angina or myocardial infarction, it is crucial to seek emergency care if the pain is not relieved after taking the medication. The 5-minute intervals for repeating the medication are appropriate to manage the chest pain effectively.


Choice A is incorrect because swallowing nitroglycerin tablets will not provide immediate relief as sublingual administration is needed.
Choice B is incorrect as transdermal patches are not used for acute chest pain relief.
Choice C is incorrect as placing 3 tablets under the tongue is excessive and may lead to adverse effects.
