Calcium channel blockers are medications that prevent calcium from entering cells of the heart and blood vessel walls, leading to decreased heart rate and dilation of blood vessels, which lowers blood pressure.

Front

Why should patients avoid grapefruit juice while taking calcium channel blockers?

Back

Grapefruit juice can increase the levels of calcium channel blockers in the blood, potentially leading to toxicity.

Front

What is the primary action of angiotensin II blockers?

Back

Angiotensin II blockers, also known as ARBs (Angiotensin Receptor Blockers), block the action of angiotensin II, a hormone that causes blood vessels to constrict, thereby lowering blood pressure.

Front

What is a common side effect of ACE inhibitors?

Back

A common side effect of ACE inhibitors is hyperkalaemia, which is an elevated level of potassium in the blood.

Front

What should a nurse do if a patient on antihypertensives reports dizziness upon standing?

Front

What are the potential consequences of abruptly stopping antihypertensive medication?

Back

Abruptly stopping antihypertensive medication can lead to rebound hypertension, which is a sudden increase in blood pressure.

Front

What is the role of lifestyle changes in managing hypertension?
