A nurse is teaching a client with angina pectoris about starting therapy with nitroglycerin tablets. The nurse should include which of the following instructions regarding how to take the medication?

Take one tablet sublingually every 5 minutes x3 to relieve chest pain.

Take this medication with 8 ounces of water.

Take this medication after each meal and at bedtime.

Take one tablet every 10 minutes x3 during an acute attack.

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is B

Explanation

Choice A rationale: Epinephrine is a potent vasoconstrictor and is typically used in emergency situations such as cardiac arrest. It is not the first-line treatment for symptomatic bradycardia1.

Choice B rationale: Atropine is the first-line medication for the treatment of bradycardia. It increases the heart rate by blocking the effects of the vagus nerve on the heart1.

Choice C rationale: Adenosine is primarily used to treat supraventricular tachycardia, not bradycardia1.

Choice D rationale: Verapamil is a calcium channel blocker used to treat high blood pressure, angina, and certain heart rhythm disorders, not typically used for bradycardia1.

A. "Heparin does not dissolve clots. It stops new clots from forming" B. "Heparin will begin dissolving clots over the next 24 hours C. "A pharmacist would be a better fit to answer that question. D. "It usually takes heparin at least 3 to 4 days to reach a therapeutic blood level."

Correct Answer is A

Explanation

Choice A rationale: Heparin is an anticoagulant that prevents new clots from forming but does not dissolve existing clots23.

Choice B rationale: Heparin does not directly dissolve clots23.

Choice C rationale: While a pharmacist can provide medication information, it is incorrect to say they would be a better fit to answer this question as nurses are trained in medication education23.

Choice D rationale: While it’s true that it takes time for heparin to reach a therapeutic blood level, this statement could be misleading because heparin does not dissolve clots23.

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