What laboratory tests are important in the context of antihypertensives to monitor systemic effects of the drugs?

Serum sodium and potassium levels, CBC, and renal function studies
Blood glucose levels exclusively
Only lipid profiles
Genetic markers for drug responsiveness

The correct answer is: Serum sodium and potassium levels, CBC, and renal function studies

Laboratory tests are important in monitoring the systemic effects of antihypertensives because these drugs can have significant impacts on various systems in the body. Option A, which includes tests for serum sodium and potassium levels, CBC, and renal function studies, is the correct choice as these tests can help detect potential drug toxicities and complications. Blood glucose levels, as mentioned in option B, may also be monitored as some antihypertensives can affect insulin sensitivity. Option C, which mentions only lipid profiles, is incorrect as this test is not commonly used to monitor antihypertensive therapy. Option D, which suggests using genetic markers, is also incorrect as there is currently no strong evidence supporting the use of genetic testing in managing antihypertensive drugs.
