Answer to Question 1

2
Rationale:
1. This nutrient does not decrease the risk of neural tube defects.
2. Folic acid supplementation prior to conception is recommended, since this decreases the risk of neural tube defects.
3. This nutrient does not decrease the risk of neural tube defects.
4. This nutrient does not decrease the risk of neural tube defects.

Answer to Question 2

A
Deficient surfactant levels is the most important factor influencing the survival of a 30-week fetus born prematurely. Although surfactant normally begins to be secreted in the lungs at 28 weeks gestation, it takes at least another 8 weeks for sufficient surfactant to be secreted and distributed throughout the alveoli. Hypothermia frequently is manifested as neonatal respiratory distress. However, this is not the major problem for the 30-week preterm neonate. Pronounced thrombocytopenia and reduced capillary permeability are not appropriate causes for neonatal respiratory distress.
