A woman with higher-order multiples is at risk for all, except which condition?

The risk factors for complications during pregnancy can vary based on the number of fetuses a woman is carrying. Higher-order multiples, which refer to pregnancies involving three or more fetuses, are associated with several potential health issues for both the mother and the babies.

In this context, the likelihood of developing gestational hypertension, preterm labor, and placenta previa is significantly elevated in women carrying higher-order multiples. Gestational hypertension occurs due to increased placental mass and heightened demand on the mother's cardiovascular system. Preterm labor is also common, as the uterus is stretched and stimulated by multiple fetuses, leading to contractions and the potential for premature delivery. Placenta previa, where the placenta covers the cervix, happens with increased frequency in multiple pregnancies due to abnormal placentation.

On the other hand, while pyelonephritis, a severe kidney infection, can occur during pregnancy, it is not specifically exacerbated or made more likely by higher-order multiples compared to singleton pregnancies. Instead, it can occur due to urinary tract infections, which may arise during pregnancy regardless of the number of fetuses. Thus, in the context of the given question, if a woman with higher-order multiples is at risk for all but one condition, it would be pyelone
