The client with coronary artery disease asks the nurse, "Why do I get this chest pain?" Which would be the most appropriate response?

The pain you have is because your heart valves are damaged.

Your heart muscle is weak and is not pumping forcefully.

The pain is caused by decreased oxygen to the heart muscle.

The layers of your heart are weak and thin.

Answer and Explanation

The Correct Answer is C

Choice A reason: The pain you have is because your heart valves are damaged is not the most appropriate response. This statement may apply to a client with valvular heart disease, but not necessarily to a client with coronary artery disease. The nurse should explain that coronary artery disease is a condition that affects the blood vessels that supply the heart, not the heart valves.

Choice B reason: Your heart muscle is weak and is not pumping forcefully is not the most appropriate response. This statement may apply to a client with heart failure, but not necessarily to a client with coronary artery disease. The nurse should explain that coronary artery disease is a condition that reduces the blood flow to the heart, not the heart's contractility.

Choice C reason: The pain is caused by decreased oxygen to the heart muscle is the most appropriate response. This statement accurately describes the cause of angina, which is the chest pain that occurs when the heart does not receive enough oxygen due to narrowed or blocked coronary arteries. The nurse should also inform the client about the factors that can trigger or relieve angina, such as physical exertion, emotional stress, cold weather, or nitroglycerin.

Choice D reason: The layers of your heart are weak and thin is not the most appropriate response. This statement may apply to a client with cardiomyopathy, but not necessarily to a client with coronary artery disease. The nurse should explain that coronary artery disease is a condition that affects the blood vessels that supply the heart, not the heart's structure.

Correct Answer is B

Explanation

Choice A reason: The international normalized ratio (INR) is a measure of the blood's ability to clot. It is not affected by ferrous sulfate therapy, which is used to treat iron deficiency anemia. The normal range of INR is 0.8 to 1.2 seconds.

Choice B reason: Hemoglobin is the protein in red blood cells that carries oxygen. It is the main indicator of anemia and the response to iron therapy. The normal range of hemoglobin for adults is 12 to 18 g/dL. A hemoglobin level of 14 g/dL suggests that the patient's anemia has improved with ferrous sulfate therapy.

Choice C reason: Serum iron is the amount of iron in the blood. It is not a reliable indicator of anemia or iron therapy, as it can fluctuate with dietary intake, infection, inflammation, and other factors. The normal range of serum iron for adults is 50 to 170 mcg/dL.

Choice D reason: Platelet count is the number of platelets in the blood. Platelets are involved in blood clotting and wound healing. They are not affected by ferrous sulfate therapy, which is used to treat iron deficiency anemia. The normal range of platelet count for adults is 150,000 to 450,000/mm3.

A. Increase the SA to AV node conduction time B. Decrease coronary artery spasm C. Diltiazem causes hyperexcitability in the myocardium D. Increase the heart rate

Correct Answer is B

Explanation

Choice A reason: Increasing the SA to AV node conduction time is not the goal of using diltiazem for variant angina. Diltiazem is a calcium channel blocker that slows down the conduction of electrical impulses in the heart, but this is not the main mechanism of action for relieving variant angina. Variant angina is caused by spasms of the coronary arteries that reduce blood flow to the heart muscle.

Choice B reason: This is the correct answer. Decreasing coronary artery spasm is the goal of using diltiazem for variant angina. Diltiazem relaxes the smooth muscle of the coronary arteries and prevents them from contracting. This improves the blood supply to the heart and reduces the pain and ischemia associated with variant angina.

Choice C reason: Diltiazem does not cause hyperexcitability in the myocardium. This is a false statement. Diltiazem has the opposite effect of reducing the contractility and excitability of the heart muscle. This lowers the oxygen demand of the heart and helps prevent anginal attacks.

Choice D reason: Increasing the heart rate is not the goal of using diltiazem for variant angina. Diltiazem actually decreases the heart rate by blocking the calcium channels in the sinoatrial node and the atrioventricular node. This reduces the workload of the heart and the oxygen consumption. A high heart rate can worsen angina by increasing the oxygen demand of the heart.
