Correct Answer is A

Explanation

Choice A rationale: Nitroglycerin tablets are typically taken sublingually (under the tongue) at the onset of chest pain. If the pain is not relieved, a second tablet may be taken 5 minutes after the first. If the pain continues for another 5 minutes, a third tablet may be used123.

Choice B rationale: Nitroglycerin tablets are not typically taken with water. They are designed to dissolve under the tongue for quick absorption into the bloodstream1.

Choice C rationale: Nitroglycerin is not typically taken after each meal and at bedtime. It is used as needed to relieve chest pain1.

Choice D rationale: While nitroglycerin can be taken every 5 minutes up to three times during an acute angina attack, it is not typically recommended to take one tablet every 10 minutes1.
