Final answer:
Pregnant women are advised against taking ACE inhibitors or ARBs due to the risk of serious fetal harm, such as renal failure, limb deformities, and cranial bone abnormalities. They should consult their healthcare provider for safe medication alternatives.
Step-by-step explanation:
The question at hand inquiries whether a pregnant woman can take angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs). These medications are typically prescribed for conditions such as high blood pressure and heart failure. However, they are not advised for pregnant women due to the significant risks they pose to the developing fetus. Research indicates that ACE inhibitors can lead to fetal renal failure and oligohydramnios, conditions which can consequently cause pulmonary hypoplasia and limb contractures in the fetus. Additionally, there is a risk of fetal cranial bone abnormalities. It is important for pregnant women to consult with their healthcare provider before taking any medication, including ACE inhibitors and ARBs, to ensure the safety of their unborn child.
