Which data indicates to the nurse that the client's current dose of simvastatin has been effective?
Total cholesterol 198 mg/dL
Blood pressure 132/80
Serum triglycerides 172 mg/dL
Low density lipoprotein (LDL) 90 mg/dL
The Correct Answer is D
Choice A reason: Total cholesterol is not the best indicator of the effectiveness of simvastatin, a drug that lowers cholesterol levels and reduces the risk of cardiovascular disease. ¹ Total cholesterol includes both LDL and HDL (high density lipoprotein), which have opposite effects on the heart and blood vessels. ² The normal range of total cholesterol for adults is less than 200 mg/dL, but this does not reflect the balance between LDL and HDL.
Choice B reason: Blood pressure is not directly related to the effectiveness of simvastatin, although high blood pressure and high cholesterol are both risk factors for cardiovascular disease. ³ Simvastatin does not lower blood pressure, but it may prevent or slow down the development of atherosclerosis, which is the narrowing and hardening of the arteries due to plaque buildup. ¹ The normal range of blood pressure for adults is less than 120/80 mmHg.
Choice C reason: Serum triglycerides are another type of fat in the blood that can contribute to cardiovascular disease. ² Simvastatin can lower triglyceride levels, but this is not its main effect. ¹ The normal range of serum triglycerides for adults is less than 150 mg/dL.
Choice D reason: LDL is the main target of simvastatin therapy, as it is the "bad" cholesterol that can cause plaque buildup and damage the arteries. ¹ Simvastatin works by inhibiting an enzyme that produces LDL in the liver. The optimal level of LDL for adults is less than 100 mg/dL, and even lower for those with high risk of cardiovascular disease. ² A LDL level of 90 mg/dL indicates that the client's current dose of simvastatin has been effective.

Correct Answer is C
Explanation
Choice A reason: You feel good because your medication is working properly is not the most appropriate statement by the nurse. This statement may imply that the client does not need to worry about their blood pressure or follow up with their doctor. The nurse should educate the client about the importance of regular monitoring and adherence to the prescribed treatment.
Choice B reason: Your blood pressure reflects how strong your heart muscle contracts is not the most appropriate statement by the nurse. This statement may confuse the client or give them a false sense of security. The nurse should explain that blood pressure is determined by the force and amount of blood pumped by the heart and the resistance of the blood vessels. The nurse should also inform the client about the normal and abnormal ranges of blood pressure and the risk factors for hypertension.
Choice C reason: Even if you are feeling good, damage can occur to your heart and kidneys is the most appropriate statement by the nurse. This statement conveys the seriousness of hypertension and its potential complications. The nurse should educate the client about the effects of high blood pressure on the vital organs and the need for preventive measures and lifestyle modifications.
Choice D reason: Have you told your doctor that you are feeling good is not the most appropriate statement by the nurse. This statement may suggest that the nurse is not interested in the client's condition or does not have the knowledge or authority to address their concerns. The nurse should communicate effectively with the client and the health care team and provide appropriate guidance and support.
Correct Answer is D
Explanation
Choice A reason: This is incorrect. Traveling to cities where the oxygen level is lower, such as high-altitude areas, can trigger a sickle cell crisis by reducing the amount of oxygen in the blood. People with sickle cell anemia should avoid such places or take precautions such as using supplemental oxygen¹².
Choice B reason: This is incorrect. Strenuous exercise does not prevent sickle cell crisis, but rather can cause it by increasing the body's oxygen demand and dehydration. People with sickle cell anemia should avoid overexertion and rest frequently during physical activity¹³.
Choice C reason: This is incorrect. Flying on commercial airlines is not prohibited for people with sickle cell anemia, as long as they stay hydrated and avoid alcohol and caffeine. However, some people may need to use supplemental oxygen during flights, especially if they have a history of acute chest syndrome or pulmonary hypertension¹⁴.
Choice D reason: This is correct. Drinking plenty of fluids when outside in hot weather is important for people with sickle cell anemia, as dehydration can cause the red blood cells to sickle and block blood vessels. Staying hydrated can help prevent or reduce the severity of sickle cell crises¹⁵.
