Final answer:
Maternal hypertension is particularly associated with conditions like Intrauterine Growth Restriction (IUGR) and multiple gestations (twins). While Rh sensitization can lead to hemolytic disease of the newborn (HDN), it is not directly linked to maternal hypertension.
Step-by-step explanation:
The conditions associated with maternal hypertension can include a variety of complications, such as diabetes, but specifically related to the question, Intrauterine Growth Restriction (IUGR) and multiple gestations like twins have clear associations. Rh sensitization, which leads to hemolytic disease of the newborn (HDN), is a serious concern in cases where an Rh-negative mother bears an Rh-positive child and develops antibodies that can attack the red blood cells of a subsequent Rh-positive fetus. This condition, however, is not directly associated with maternal hypertension. Similarly, while the risk of having a fetus with trisomies such as trisomy 21 (Down syndrome) increases with maternal age, this condition is also not directly linked to maternal hypertension. Other complications such as fetal anomalies can be a result of various factors, including genetic and environmental influences, and not necessarily maternal hypertension.
