Practice Question
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?
Answer Choices:
Correct Answer:
Lack of sufficient oxygen to the myocardium.
Rationale:
🟨 Coronary artery disease (CAD) occurs when plaque buildup in the coronary arteries reduces blood flow to the myocardium, especially during exertion or stress.
🟨 The myocardial cells require oxygen to function, and when oxygen supply is insufficient (ischemia), the result is angina pectoris, or chest pain.
🟨 This pain is the heart's response to hypoxia, which leads to the accumulation of lactic acid and other metabolites, stimulating nerve endings and producing a squeezing or pressure-like chest discomfort.
🟨 Although increased workload and nutrient demand contribute, the critical issue causing pain is the lack of oxygenated blood reaching cardiac tissue.
🟨 Understanding this helps patients grasp the importance of medications (like nitrates, beta-blockers) and lifestyle changes aimed at improving oxygen delivery and reducing demand.
