What are potential risks to a fetus resulting from PIH?

The potential risks to a fetus resulting from pregnancy-induced hypertension (PIH) include inadequate placental perfusion. PIH can lead to conditions such as preeclampsia, which often results in reduced blood flow to the placenta. This inadequacy in perfusion can compromise the delivery of essential nutrients and oxygen to the fetus, potentially leading to growth restrictions, low birth weight, and other serious complications.

The other options, while they may have varying associations with pregnancy or health, do not directly relate to the primary complications posed by PIH. Increased heart rate can occur in various contexts and isn't specific to effects resulting from PIH. Excessive weight gain may occur during pregnancy but does not directly relate to the risks posed to the fetus specifically due to PIH. Lastly, a higher likelihood of mutation is not a recognized consequence of PIH; mutation risks are generally more linked to genetic factors and environmental exposures, rather than the blood pressure condition defined by PIH. Hence, inadequate placental perfusion is a direct consequence of PIH that can significantly impact fetal health.
