Final answer:
Methyldopa (Aldomet) is the preferred medication for managing mild-to-moderate hypertension during pregnancy, not beta blockers or ACE inhibitors, which can have harmful effects on the fetus.
Step-by-step explanation:
The statement that is true about hypertension (HTN) during pregnancy is: Methyldopa (Aldomet) is the drug of first choice for control of mild-to-moderate HTN during pregnancy. Beta blockers can be prescribed in pregnancy, but with caution, and not all are considered safe. ACE inhibitors (angiotensin converting enzyme inhibitors) are contraindicated during pregnancy, especially in the second and third trimesters, due to their risks of causing fetal renal failure, pulmonary hypoplasia, and limb contractures as well as cranial bone abnormalities. It's paramount for hypertension management to be conducted under the guidance of a healthcare provider, and any medication changes should be discussed with a physician who can assess the risks and benefits in the context of pregnancy.
