A nurse is caring for a client who is newly-admitted and has angina. The client asks the nurse, "Why am I taking nitroglycerin?" Which of the following responses should the nurse make?

"Nitroglycerin decreases chest pain by dissolving blood clots that are occluding the arteries."

"Nitroglycerin dilates cardiac blood vessels to deliver more oxygen to the heart"

"Nitroglycerin relieves nausea and prevents vomiting, which could lead to aspiration."

"Nitroglycerin acts as a bronchodilator to open small airways and decrease shortness of breath."

Answer and Explanation

The Correct Answer is B

A. Nitroglycerin does not dissolve blood clots; it works by dilating blood vessels to increase blood flow.

B. Nitroglycerin dilates the coronary arteries, increasing oxygen delivery to the heart muscle and relieving angina, which is caused by reduced blood flow to the heart.

C. Nitroglycerin is not used to relieve nausea or prevent vomiting; it is used primarily to manage chest pain.

D. Nitroglycerin is not a bronchodilator; it does not affect the airways directly but rather improves blood flow to the heart.
