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 lowing responses should the nurse make?

"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."

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

Answer and Explanation

The Correct Answer is A

A. "Nitroglycerin dilates cardiac blood vessels to deliver more oxygen to the heart." Nitroglycerin works by dilating the coronary arteries, increasing blood flow and oxygen delivery to the heart muscle, thereby reducing angina.

B. "Nitroglycerin relieves nausea and prevents vomiting, which could lead to aspiration." Nitroglycerin does not have an antiemetic function or impact nausea and vomiting.

C. "Nitroglycerin acts as a bronchodilator to open small airways and decrease shortness of breath." Nitroglycerin is not a bronchodilator. It does not act on the airways but instead works on blood vessels.

D. "Nitroglycerin decreases chest pain by dissolving blood clots that are occluding the arteries." Nitroglycerin does not dissolve blood clots. Thrombolytic agents are used for clot dissolution, not nitroglycerin.

Correct Answer is D

Explanation

A. Nitroglycerin: Nitroglycerin is used to relieve chest pain by dilating coronary arteries and increasing blood flow. However, in the immediate setting of a suspected MI, oxygen is prioritized to ensure adequate oxygenation.

B. Aspirin: Aspirin is essential in the early treatment of MI to prevent further clot formation by inhibiting platelet aggregation, but oxygen would still come first if the client’s oxygenation is compromised.

C. Morphine: Morphine is used for pain relief and to reduce anxiety and oxygen demand on the heart. However, it is administered after ensuring oxygen supply.

D. Oxygen: Oxygen should be administered first in a suspected myocardial infarction to ensure the heart and tissues receive adequate oxygen, especially if the patient is hypoxic.

A. Eggs B. Milk C. Beans D. Liver

Correct Answer is C

Explanation

A. Eggs: Eggs, particularly the yolks, are high in cholesterol and should be limited in a low-cholesterol diet.

B. Milk: Full-fat milk is high in saturated fat and cholesterol. If the client consumes milk, it should be low-fat or non-fat varieties.

C. Beans: Beans are high in fiber and low in fat and cholesterol. They are an excellent choice for a low-cholesterol diet.

D. Liver: Liver is high in cholesterol and should be avoided by clients following a low-cholesterol diet.
