Answer to Question 1

D
All of the listed conditions, and others, increase the risk of the neonate developing RDS.

Answer to Question 2

B
As a consequence of alveolar hypoxia, the neonate can develop pulmonary vasoconstriction and transient pulmonary hypertension. This will lead to a right-to-left shunt as blood flows through the foramen ovale and ductus arteriosus. This results in a partial return to fetal circulation. There is no change in systemic blood flow and flow to the gut.
