The client with coronary artery disease asks the nurse, "Why do I get this chest pain?" Which would be the most appropriate response?

Choice A reason: Furosemide 40 mg PO daily is not the medication that the nurse should administer for chest pain. Furosemide is a diuretic that reduces fluid volume and lowers blood pressure, but it does not relieve anginal pain.

Choice B reason: Diltiazem 30 mg PO daily is not the medication that the nurse should administer for chest pain. Diltiazem is a calcium channel blocker that relaxes the blood vessels and lowers blood pressure, but it does not act quickly enough to relieve acute anginal pain.

Choice C reason: Metoprolol 25 mg PO bid is not the medication that the nurse should administer for chest pain. Metoprolol is a beta blocker that slows down the heart rate and lowers blood pressure, but it does not act quickly enough to relieve acute anginal pain.

Choice D reason: Nitroglycerin 0.4 mg SL PRN is the medication that the nurse should administer for chest pain. Nitroglycerin is a nitrate that dilates the coronary arteries and increases blood flow to the heart, thus relieving anginal pain. It is given sublingually (under the tongue) as needed for chest pain.

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.
