Question

The obstetric nurse is assisting the delivery 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

Surfactant production begins early in gestation, but adequate levels for lung compliance and reduced respiratory distress are typically reached around 32 to 34 weeks of pregnancy.

Step-by-step explanation:

The obstetric nurse preparing for the respiratory needs of a preterm neonate needs to be aware that surfactant production in utero begins early but is not generally adequate for effective lung compliance until about the eighth month of pregnancy, which correlates approximately to 32 to 34 weeks gestation. Sufficient alveolar precursors have matured around week 28, allowing a baby born prematurely at this time to potentially breathe on its own, albeit with potential for respiratory distress. However, full surfactant levels and lung maturity to prevent respiratory distress more reliably are reached later, around 32 to 34 weeks gestation.

Therefore, the answer to the question, "In preparing for the respiratory needs of the neonate, the nurse is aware that surfactant is formed in utero around:" is c) 32 to 34 weeks.
