Which of the following statements concerning polyhydramnios is true ?
**Core Concept**
Polyhydramnios is a condition characterized by an excessive accumulation of amniotic fluid in pregnancy, which can lead to complications such as preterm labor, fetal distress, and maternal discomfort.
**Why the Correct Answer is Right**
Polyhydramnios is often associated with fetal anomalies or maternal diabetes, which can disrupt normal fetal swallowing and urine production. This imbalance leads to an accumulation of amniotic fluid, contributing to polyhydramnios. In cases of maternal diabetes, fetal hyperglycemia can cause polyuria, further exacerbating the condition.
**Why Each Wrong Option is Incorrect**
**Option A:** Polyhydramnios is not typically associated with intrauterine growth restriction (IUGR), as IUGR is more commonly linked to oligohydramnios due to decreased fetal urine production.
**Option B:** While maternal hypertension can have various fetal effects, it is not a primary cause of polyhydramnios. Hypertension may lead to decreased fetal urine production, contributing to oligohydramnios, rather than polyhydramnios.
**Option C:** Polyhydramnios is not directly related to the gestational age of the fetus. While the condition may be more common in term pregnancies, it can occur at any gestational age.
**Clinical Pearl / High-Yield Fact**
It's essential to recognize that polyhydramnios can be a sign of underlying fetal or maternal pathology, making prompt evaluation and management crucial to prevent complications.
**Correct Answer: C. Polyhydramnios can occur at any gestational age.**
