Final answer:
African Americans are less likely to respond positively to ACE inhibitors and beta-blockers compared to other antihypertensive medications like calcium channel blockers and diuretics.
Step-by-step explanation:
The responses of African Americans to antihypertensive medication therapy can differ from those of other racial groups. Studies have indicated that African Americans may respond differently to certain classes of antihypertensive drugs, such as ACE inhibitors and beta-blockers. They tend to have a better response to calcium channel blockers and diuretics for blood pressure control. Therefore, the correct statement regarding African Americans' responses to antihypertensive medication therapy is that African Americans are less likely to respond positively to ACE inhibitors and beta-blockers. Various factors contribute to these differences, including genetic variations, the prevalence of comorbid conditions such as diabetes, and socioeconomic factors.
