Inpatient Obstetric Nurse Practice Exam 2025 – Complete Prep Guide

Question: 1 / 400

What defines a postterm infant?

Born after 38 weeks gestation

Born after 40 weeks gestation

Born after 42 weeks gestation

A postterm infant is defined as one who is born after 42 weeks of gestation. This classification is critical for healthcare providers to understand because postterm infants may face increased risks for complications such as macrosomia, meconium aspiration, and stillbirth. The timing of delivery is essential in managing both maternal and fetal health, especially when gestation extends beyond the typical duration.

In contrast, being born after 38 weeks or 40 weeks leads to the classifications of late preterm and postmature, respectively, but does not fit the criteria for a postterm designation. Likewise, a birth before 37 weeks marks a preterm infant, which is not relevant in defining postterm status. Recognizing the specific timing associated with postterm births is important in obstetric care to ensure the appropriate monitoring and intervention strategies are in place.
