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?

Choice A reason: Increasing calcium in the diet is not the most important instruction for a client with hypertension. Calcium is a mineral that helps maintain bone health and muscle contraction, but it does not have a significant effect on blood pressure. The nurse should advise the client to limit sodium, fat, and alcohol intake, and to eat more fruits, vegetables, and whole grains.

Choice B reason: Obtaining blood pressure checks twice a year is not the most important instruction for a client with hypertension. This frequency is too low for a client who has a chronic condition that requires close monitoring and treatment. The nurse should advise the client to check their blood pressure regularly, preferably at home, and to report any abnormal readings to their health care provider.

Choice C reason: Monitoring weight on a weekly basis is not the most important instruction for a client with hypertension. Weight is a factor that can influence blood pressure, but it is not the only one. The nurse should advise the client to maintain a healthy weight and to lose weight if they are overweight or obese, but not to focus on the scale alone.

Choice D reason: Getting regular physical activity is the most important instruction for a client with hypertension. Physical activity can lower blood pressure by strengthening the heart, improving blood circulation, reducing stress, and preventing or managing other risk factors, such as obesity, diabetes, and high cholesterol. The nurse should advise the client to engage in moderate aerobic exercise for at least 30 minutes a day, five days a week, and to consult their health care provider before starting any new exercise program.

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.
