A patient has recently started ferrous sulfate 500 mg by mouth two times per day for anemia. Which of the following data would indicate to the nurse that the therapy is successful?
International normalized ratio 1.3 seconds
Hemoglobin 14 g/dL
Serum iron 150 mcg/dL
Platelet count 250,000/mm3
The Correct Answer is B
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.

Correct Answer is D
Explanation
Choice A reason: Furosemide 40 mg PO daily is not the medication that the nurse should administer for chest pain. Furosemide is a diuretic that reduces fluid volume and lowers blood pressure, but it does not relieve anginal pain.
Choice B reason: Diltiazem 30 mg PO daily is not the medication that the nurse should administer for chest pain. Diltiazem is a calcium channel blocker that relaxes the blood vessels and lowers blood pressure, but it does not act quickly enough to relieve acute anginal pain.
Choice C reason: Metoprolol 25 mg PO bid is not the medication that the nurse should administer for chest pain. Metoprolol is a beta blocker that slows down the heart rate and lowers blood pressure, but it does not act quickly enough to relieve acute anginal pain.
Choice D reason: Nitroglycerin 0.4 mg SL PRN is the medication that the nurse should administer for chest pain. Nitroglycerin is a nitrate that dilates the coronary arteries and increases blood flow to the heart, thus relieving anginal pain. It is given sublingually (under the tongue) as needed for chest pain.
Correct Answer is C
Explanation
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.
