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:

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: This is not a correct answer. A decrease in urination is not a common side effect of amlodipine. Amlodipine is a calcium channel blocker that lowers the blood pressure and relaxes the blood vessels. Amlodipine does not affect the kidney function or the urine output, unless there is an underlying renal problem or a drug interaction. The client should monitor their urination, but not expect a decrease.

Choice B reason: This is the correct answer. An increase in lower extremity edema is a common side effect of amlodipine. Amlodipine can cause fluid retention and swelling in the legs, ankles, or feet. This is due to the dilation of the blood vessels and the leakage of fluid into the tissues. The client should monitor their weight and the size of their lower extremities, and report any significant changes to their health care provider. The client may also elevate their legs, wear compression stockings, or take diuretics to reduce the edema.

Choice C reason: This is not a correct answer. Tachycardia during exercise is not a common side effect of amlodipine. Amlodipine can lower the heart rate and the cardiac output, which can reduce the oxygen demand of the heart. Amlodipine does not cause an increase in the heart rate, unless there is an underlying cardiac problem or a drug interaction. The client should monitor their pulse and blood pressure, but not expect tachycardia.

Choice D reason: This is not a correct answer. An increase in bowel motility is not a common side effect of amlodipine. Amlodipine does not affect the gastrointestinal system or the digestion, unless there is an allergic reaction or a drug interaction. Amlodipine can cause some gastrointestinal side effects, such as nausea, abdominal pain, or constipation, but not an increase in bowel motility. The client should monitor their bowel movements, but not expect an increase.
