The nurse knows that which group(s) of antihypertensive drugs are less effective in African-American clients?

• A. Beta blockers and ACE inhibitors
• B. Diuretics
• C. Calcium channel blockers and vasodilators
• D. Alpha blockers

Answer: (A)

When treating hypertension, the most effective drug choices can differ by race due to underlying physiology. Many African-American patients have lower renin activity and more salt sensitivity, leading to volume expansion as a major driver of high blood pressure. Drugs that address volume or resistance directly without relying on reducing renin output tend to work better as first-line therapy in this group.

Beta blockers and ACE inhibitors are less effective when used alone in many African-American clients because their primary actions involve lowering renin-mediated effects (beta blockers reduce renin release, ACE inhibitors block angiotensin II formation). With low renin activity, these mechanisms don’t translate into as large a drop in blood pressure, making them less potent as stand-alone initial therapy. They can still be valuable in combination with other agents or for other health reasons, but as initial monotherapy, diuretics and calcium channel blockers are typically favored for better BP control in this population.
