A nurse is assessing a preterm newborn who is at 32 weeks of gestation. Which of the following finding should the nurse expect?

Correct Answer: B

Rationale: A preterm newborn at 32 weeks of gestation is usually characterized by hip flexion posturing and a popliteal angle of less than 90 degrees. The popliteal angle is the angle at the back of the knee joint when the leg is flexed, and a value of less than 90 degrees is commonly seen in preterm newborns due to their muscle tone immaturity. This finding is consistent with the developmental stage of a preterm infant at 32 weeks gestation.

Correct Answer: C

Rationale: The foramen ovale is a normal fetal structure that allows blood to bypass the lungs by shunting blood from the right atrium to the left atrium. This is essential during fetal development since the lungs are not functioning until birth. After birth, when the baby takes its first breaths and the lungs start working, the pressure in the left atrium increases due to the increased blood flow from the pulmonary circulation. This increased pressure in the left atrium causes the foramen ovale to close, preventing blood from flowing from the right atrium to the left atrium. Therefore, the closure of the foramen ovale is a result of the increased pressure in the left atrium rather than any other cardiovascular changes.

Correct Answer: C

Rationale: Balanced meals and regular blood sugar monitoring are essential for managing gestational diabetes.

Correct Answer: B

Rationale: Polyhydramnios increases the risk of preterm labor due to uterine overdistension, requiring close monitoring.

Correct Answer: B

Rationale: Lamaze emphasizes comfort and partner support, aligning with creating a calm environment for labor.
