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
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.

Correct Answer is B
Explanation
A. Performing movements until the patient reports pain is inappropriate in passive range of motion, as the goal is to maintain joint function without causing discomfort.
B. Moving each joint to the point of resistance helps to maintain flexibility and prevent stiffness without causing harm, making this the appropriate technique.
C. Repeating movements five times by the patient is not applicable for passive range of motion, which is performed by the nurse on a patient who cannot do it themselves.
D. While smooth movements are essential, they should not be done quickly; the focus should be on the patient's comfort and safety, avoiding rapid or jerky motions.
