Which class of medications should not be used for BP control in a sexually active teenager taking birth control?

The correct answer, ACE inhibitors, should not be used for blood pressure control in a sexually active teenager taking birth control due to the potential risk of teratogenic effects on a developing fetus should pregnancy occur. ACE inhibitors are known to be harmful during pregnancy, particularly in the second and third trimesters, as they can affect fetal development, leading to issues such as renal impairment, oligohydramnios, and other serious complications.

While other classes of antihypertensive medications can generally be used safely in sexually active individuals, ACE inhibitors' specific contraindication stems from their ability to cause significant harm to a fetus. Therefore, in managing blood pressure in this demographic, it is critical to consider the potential for unintended pregnancy and the implications of any prescribed medication.

In contrast, beta blockers, calcium channel blockers, and diuretics do not carry the same level of risk for teratogenicity and can be used for blood pressure management in sexually active teenagers who are on birth control. Each of those classes operates through different mechanisms and does not have the same adverse effects when it comes to fetal development, which makes them more suitable alternatives in this context.
