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.

So, the correct answer is A, after analysing all choices.
