A patient has experienced a myocardial infarction. On which primary blood vessel will the nurse focus care to reduce ischemia?

Superior vena cava

Carotid artery

Pulmonary artery

Coronary artery

Answer and Explanation

The Correct Answer is D

A. The superior vena cava is responsible for returning deoxygenated blood from the upper body to the heart and is not directly involved in myocardial ischemia.
B. The carotid artery supplies blood to the brain and is not the primary focus in the context of myocardial infarction.
C. The pulmonary artery carries deoxygenated blood from the heart to the lungs and is not involved in coronary circulation.
D. The coronary arteries supply blood to the heart muscle itself. Ischemia during a myocardial infarction occurs when these arteries are blocked or narrowed, leading to a lack of blood flow and oxygen to the heart tissue.
