The nurse recognizes that the rationale for the medical prescription of aspirin 81 mg PO daily and clopidogrel 75 mg PO daily for the client with coronary artery disease is that these medications:
Have analgesic properties without sedation
Can trigger vasodilation and improve blood flow
Improve contractility and decrease afterload
Inhibit platelet aggregation and clot formation
The Correct Answer is A
Choice A reason: Having analgesic properties without sedation is not the rationale for prescribing aspirin and clopidogrel for coronary artery disease. Aspirin and clopidogrel are antiplatelet drugs that prevent blood clots from forming in the arteries that supply the heart. They do not have significant analgesic or sedative effects.
Choice B reason: Triggering vasodilation and improving blood flow is not the rationale for prescribing aspirin and clopidogrel for coronary artery disease. Aspirin and clopidogrel do not directly cause vasodilation or increase blood flow. They work by reducing the stickiness of platelets and preventing them from clumping together and blocking the arteries.
Choice C reason: Improving contractility and decreasing afterload is not the rationale for prescribing aspirin and clopidogrel for coronary artery disease. Aspirin and clopidogrel do not affect the contractility or the afterload of the heart. They act on the blood vessels and the blood cells, not on the heart muscle. Contractility and afterload are influenced by other drugs such as beta-blockers, calcium channel blockers, and angiotensin-converting enzyme inhibitors.
Choice D reason: This is the correct answer. Inhibiting platelet aggregation and clot formation is the rationale for prescribing aspirin and clopidogrel for coronary artery disease. Aspirin and clopidogrel are antiplatelet drugs that interfere with the function of platelets, which are blood cells that help with clotting. By inhibiting platelet aggregation and clot formation, aspirin and clopidogrel reduce the risk of heart attack and stroke in people with coronary artery disease.

Correct Answer is D
Explanation
Choice A reason: Vitamin B12 does not contribute to the increased production of RBCs after significant blood loss. Vitamin B12 is a type of vitamin that is essential for the normal formation and maturation of red blood cells (RBCs), which carry oxygen throughout the body. ¹ However, vitamin B12 does not increase the production of RBCs in response to blood loss. That is the role of erythropoietin, a hormone that stimulates the bone marrow to produce more RBCs. ²
Choice B reason: Vitamin B12 is not needed to prevent excessive production of red blood cells. Vitamin B12 is needed for the normal production of red blood cells, not for the prevention of overproduction. Excessive production of red blood cells, also known as polycythemia, can cause the blood to become thick and viscous, increasing the risk of clotting and stroke. ³ Polycythemia can be caused by various factors, such as smoking, dehydration, or genetic mutations, but not by a lack of vitamin B12.
Choice C reason: Vitamin B12 is not needed to prevent RBCs from sticking together. Vitamin B12 is needed for the normal formation and maturation of RBCs, not for the prevention of aggregation. RBCs can stick together and form clumps, also known as rouleaux, which can impair blood flow and oxygen delivery. Rouleaux can be caused by various factors, such as inflammation, infection, or cancer, but not by a lack of vitamin B12.
Choice D reason: Vitamin B12 is needed for the normal formation and maturation of RBCs, but it cannot be absorbed by the body without a substance called intrinsic factor. Intrinsic factor is a protein that is produced by the stomach and binds to vitamin B12, allowing it to be absorbed by the small intestine. ¹ Pernicious anemia is a type of anemia that occurs when the stomach does not produce enough intrinsic factor, leading to vitamin B12 deficiency. The only way to treat pernicious anemia is by giving vitamin B12 injections, which bypass the need for intrinsic factor.
Correct Answer is D
Explanation
Choice A reason: This is a high-fat, high-sodium, and high-calorie meal that is not suitable for a client with hypertension. Fried foods, processed meats, and baked beans are sources of saturated fat and sodium that can raise blood pressure and cholesterol levels. Cake is a source of added sugar that can contribute to obesity and diabetes.
Choice B reason: This is a moderate-fat, moderate-sodium, and moderate-calorie meal that is not ideal for a client with hypertension. Fried flounder and tomato soup are sources of fat and sodium that can increase blood pressure. White rice is a refined carbohydrate that can spike blood sugar levels and increase the risk of diabetes.
Choice C reason: This is a high-fat, high-sodium, and high-calorie meal that is not appropriate for a client with hypertension. Barbecue pulled pork sandwich, mashed potatoes, and ice cream are sources of saturated fat and sodium that can elevate blood pressure and cholesterol levels. Fresh green beans are the only healthy component of this meal.
Choice D reason: This is a low-fat, low-sodium, and low-calorie meal that is suitable for a client with hypertension. Baked tuna, fresh broccoli, brown rice, and fresh cantaloupe are sources of lean protein, fiber, complex carbohydrates, vitamins, minerals, and antioxidants that can lower blood pressure and cholesterol levels, prevent obesity and diabetes, and promote cardiovascular health.
