A nurse is teaching a client with hypertension about antihypertensive drugs. Which of the following statements by the client indicates an understanding of the teaching?

Antihypertensive drugs can lower blood pressure by affecting different parts of the cardiovascular system.This is a general statement that covers the various mechanisms of action of different classes of antihypertensive drugs, such as beta blockers, diuretics, ACE inhibitors, ARBs, calcium channel blockers, alpha blockers, and renin inhibitors.Each class of drugs has a different way of influencing the heart rate, blood vessel tone, blood volume, or hormonal activity that regulate blood pressure.

Choice A is wrong because antihypertensive drugs do not work by increasing the blood flow to the heart and kidneys.In fact, some antihypertensive drugs may decrease the blood flow to these organs as a side effect.

Choice C is wrong because antihypertensive drugs are not safe to use with any other medications or supplements.There are many potential drug interactions that can affect the efficacy or safety of antihypertensive drugs.For example, NSAIDs can reduce the blood pressure lowering effect of some antihypertensive drugs and increase the risk of kidney damage. Therefore, patients should always consult their doctor or pharmacist before taking any other medications or supplements with antihypertensive drugs.

Choice D is wrong because antihypertensive drugs will not cure hypertension if taken as prescribed.Hypertension is a chronic condition that requires lifelong management and lifestyle changes.Antihypertensive drugs can only control the blood pressure and prevent complications, but they do not address the underlying causes of hypertension.If patients stop taking their antihypertensive drugs, their blood pressure will likely rise again and increase the risk of heart attack, stroke, and kidney failure.

Hydrochlorothiazide is a thiazide diuretic that lowers blood pressure by increasing urine output. However, it also causes potassium loss, which can lead to muscle weakness and fatigue.Therefore, the client should consume foods that are rich in potassium, such as bananas, oranges, potatoes, and spinach.

Choice A is wrong because drinking more fluids can increase blood volume and blood pressure, which is not desirable for a client who has hypertension.Dehydration is not a common side effect of hydrochlorothiazide.

Choice C is wrong because hydrochlorothiazide does not affect blood sugar levels directly. However, it can interact with some antidiabetic medications and increase the risk of hypoglycemia.Therefore, the client should monitor blood sugar levels regularly if taking both medications.

Choice D is wrong because hydrochlorothiazide does not increase sensitivity to sunlight. However, it can cause photosensitivity reactions in some clients, such as rash, itching, or redness of the skin. Therefore, the client should use sunscreen and wear protective clothing when exposed to sunlight.
