Answer to Question 1

ANS: B
All newborns have a brief period of asphyxia during which they become hypoxic, leading to lowered pH. Subsequently carbon dioxide levels begin to rise and this stimulates the respiratory center in the brain to initiate respirations.

Answer to Question 2

ANS: C
A fetus has produced sufficient surfactant for independent respiratory function by about gestational weeks 34 to 36. Hence, a baby born at 33 weeks' gestation is at risk for not having enough surfactant. Factors that can lead to increased surfactant production include mothers with White classification D, F, and R diabetes; maternal hypertension; and maternal heroin addiction. Fetal hemolytic disorders and multiple gestation are risk factors for decreased surfactant production. Incorrect dates may be important, but this is not a factor that leads to increased surfactant production.
