The client is prescribed rosuvastatin 10 mg PO daily. What information will the nurse provide in the teaching about this medication?
Stop the medication if you develop a change in vision.
Monitor body weight weekly.
Report muscle weakness or pain.
Have biannual renal function studies.
The Correct Answer is C
Choice A reason: Stopping the medication if the client develops a change in vision is not the information that the nurse should provide in the teaching about rosuvastatin. Rosuvastatin is a drug that lowers the cholesterol and prevents the complications of cardiovascular disease. It belongs to a class of drugs called statins, which work by inhibiting an enzyme that produces cholesterol in the liver. Change in vision is not a common or serious side effect of rosuvastatin, and it may be caused by other factors, such as eye strain, infection, or disease. The nurse should not advise the client to stop the medication without consulting the healthcare provider, as this may increase the risk of adverse outcomes, such as heart attack or stroke.
Choice B reason: Monitoring body weight weekly is not the information that the nurse should provide in the teaching about rosuvastatin. Rosuvastatin is a drug that lowers the cholesterol and prevents the complications of cardiovascular disease. It belongs to a class of drugs called statins, which work by inhibiting an enzyme that produces cholesterol in the liver. Body weight is not a direct indicator of the effectiveness or safety of rosuvastatin, and it may fluctuate due to various factors, such as diet, exercise, or fluid retention. The nurse should encourage the client to maintain a healthy weight and lifestyle, but not to focus on the weekly changes in body weight.
Choice C reason: Reporting muscle weakness or pain is the information that the nurse should provide in the teaching about rosuvastatin. Rosuvastatin is a drug that lowers the cholesterol and prevents the complications of cardiovascular disease. It belongs to a class of drugs called statins, which work by inhibiting an enzyme that produces cholesterol in the liver. However, statins can also cause muscle damage, which can manifest as weakness, pain, tenderness, or cramps. This can be a sign of a serious condition called rhabdomyolysis, which is the breakdown of muscle tissue that can lead to kidney failure or death. The nurse should instruct the client to report any muscle symptoms to the healthcare provider as soon as possible, and to avoid taking any other drugs or supplements that may interact with rosuvastatin and increase the risk of muscle damage.
Choice D reason: Having biannual renal function studies is not the information that the nurse should provide in the teaching about rosuvastatin. Rosuvastatin is a drug that lowers the cholesterol and prevents the complications of cardiovascular disease. It belongs to a class of drugs called statins, which work by inhibiting an enzyme that produces cholesterol in the liver. Renal function studies are tests that measure the health and function of the kidneys, which are responsible for filtering the blood and removing waste and excess fluid. Rosuvastatin is not known to cause significant kidney damage, and it is excreted mainly by the liver. The nurse should not recommend the client to have biannual renal function studies, as this may be unnecessary and costly. The nurse should advise the client to follow the healthcare provider's orders regarding the frequency and type of laboratory tests that are needed to monitor the effects of rosuvastatin.

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 A
Explanation
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.
