Question

The obstetric nurse is assisting the birth of a preterm neonate. In preparing for the respiratory needs of the neonate, the nurse is aware that surfactant is formed in utero around:

a)34 to 36 weeks.
b)36 to 38 weeks.
c)32 to 34 weeks.
d)30 to 32 weeks.

Answer 1

In utero surfactant formation, crucial for a neonate's breathing, typically becomes adequate for effective lung compliance around 32 to 34 weeks of gestation.

Step-by-step explanation:

The formation of surfactant in utero is crucial for the neonate's ability to breathe independently upon birth. Surfactant production begins around week 24 of gestation and increases as the pregnancy progresses. However, levels of surfactant are typically not adequate to ensure effective lung compliance until about the eighth month, which correlates with 32 to 34 weeks of gestation. This information helps us understand that the obstetric nurse should be aware that surfactant is formed in utero around 32 to 34 weeks of gestation (option c), making this a critical time frame for ensuring the respiratory needs of a preterm neonate are met.
