The nurse is reinforcing teaching to the patient about the cause of pain from coronary artery disease. The nurse would evaluate the patient as understanding the education if the patient stated which of the following causes the pain from coronary artery disease?

Lack of sufficient oxygen to the myocardium.

Increased cardiac workload.

Interrupted electrical activity to areas of the heart.

Lack of nutrients to the heart.

Answer and Explanation

The Correct Answer is A

Choice A reason: The myocardium requires a constant supply of oxygen to function properly. Coronary artery disease (CAD) causes a reduction in blood flow due to narrowed or blocked coronary arteries, leading to a lack of oxygen in the heart muscle, which can result in angina or chest pain.

Choice B reason: While increased cardiac workload can exacerbate chest pain, it is not the primary cause of pain in CAD. The pain is primarily due to ischemia, which is the lack of oxygen and nutrients to the heart tissue due to reduced blood flow.

Choice C reason: Interrupted electrical activity can lead to arrhythmias or heart attack, but it is not the direct cause of pain in CAD. The pain is related to ischemia, not electrical disturbances.

Choice D reason: A lack of nutrients, including oxygen, to the heart does contribute to the pain experienced in CAD; however, the primary factor is the insufficient oxygen supply, which is explicitly stated in choice A.
