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?

Interrupted electrical activity to areas of the heart

Lack of sufficient oxygen to the myocardium

Increased cardiac workload

Lack of nutrients into the heart

Answer and Explanation

The Correct Answer is B

Choice A reason: Interrupted electrical activity to areas of the heartWhen it comes to the pain associated with coronary artery disease (CAD), interrupted electrical activity is not the primary cause. While abnormal electrical activity can lead to arrhythmias, it is not the primary source of pain in CAD. The pain in CAD is primarily related to inadequate blood flow and oxygen supply to the heart muscle.

Choice B reason: Lack of sufficient oxygen to the myocardiumThis is the correct answer. Coronary artery disease results in the narrowing or blockage of coronary arteries, which supply oxygen-rich blood to the heart muscle. When these arteries become narrowed due to plaque buildup (atherosclerosis), the heart muscle does not receive enough oxygen. This insufficient oxygen supply leads to chest pain (angina) and discomfort.

Choice C reason: Increased cardiac workloadWhile increased cardiac workload can contribute to heart-related symptoms, it is not the primary cause of pain in coronary artery disease. Increased workload may occur during physical exertion or stress, but the underlying issue in CAD is the reduced blood flow due to narrowed or blocked arteries.

Choice D reason: Lack of nutrients into the heartWhile nutrients are essential for overall heart health, the primary concern in coronary artery disease is the lack of oxygen supply. The pain associated with CAD is primarily related to inadequate oxygen delivery to the heart muscle, not specifically a lack of nutrients.

Correct Answer is D

Explanation

Choice A reason: Grief after a major loss can indeed mimic the symptoms of depression, but it is not considered clinical depression unless the symptoms persist and meet specific criteria.

Choice B reason: Depression is common after a myocardial infarction (MI) due to the emotional and physical stress of the event and recovery process.

Choice C reason: Children and adolescents can and do suffer from depression, and it is important for it to be recognized and treated appropriately.

Choice D reason: Depression is more common in women than in men, which makes the statement incorrect.

A. “It is done to increase blood flow to the myocardium.” B. “It will decrease blood flow to the coronary arteries.” C. “It cures coronary artery disease.” D. “It prevents spasms of the coronary arteries.”

Correct Answer is A

Explanation

Choice A Reason:Coronary artery bypass graft surgery (CABG) is not primarily performed to increase blood flow to the myocardium. Instead, it aims to restore blood flow to areas of the heart affected by blockages.

Choice B Reason:CABG does not intentionally decrease blood flow to the coronary arteries. On the contrary, it creates a new pathway to bypass blocked or partially blocked coronary arteries, improving blood flow to the heart muscle.

Choice C Reason:The primary purpose of CABG is to treat coronary artery disease by restoring blood flow to areas of the heart that aren't receiving enough blood. It involves using healthy blood vessels (usually from the chest or leg) to create a detour around blockages. By doing so, CABG improves heart function and reduces symptoms related to ischemia.

Choice D Reason:While CABG can indirectly prevent spasms of the coronary arteries by improving blood flow, it is not its primary purpose.
