A nurse is caring for a patient who has a suspected myocardial infarction. Which of the following should the nurse administer first?

Nitroglycerin

Aspirin

Morphine

Oxygen

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is A

Explanation

A. Obtain a pair of slipper socks for the client. This is an appropriate action. Slipper socks can provide warmth and help improve circulation, promoting comfort.

B. Increase the client's oral fluid intake. While hydration is important for overall health, it will not directly address the cold feet caused by poor circulation in this scenario.

C. Place a moist heating pad under the client's feet. Heating pads, especially moist ones, can increase the risk of burns and should be avoided in clients with vascular occlusions, as they may have decreased sensation.

D. Rub the client's feet briskly for several minutes. Rubbing the feet briskly could cause skin breakdown and injury due to fragile skin and impaired circulation.

A. "Nitroglycerin dilates cardiac blood vessels to deliver more oxygen to the heart." B. "Nitroglycerin relieves nausea and prevents vomiting, which could lead to aspiration." C. "Nitroglycerin acts as a bronchodilator to open small airways and decrease shortness of breath." D. "Nitroglycerin decreases chest pain by dissolving blood clots that are occluding the arteries."

Correct Answer is A

Explanation

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.
