The nurse is caring for a woman who gave birth to a preterm infant. The nurse is aware that what are possible causes of preterm delivery? (Select all that apply.)
- A. Placenta previa
- B. Gestational diabetes
- C. Pregnancy-induced hypertension
- D. Hyperemesis gravidarum

- A. Check tube placement by injecting air into the stomach.
- B. Weigh the infant before the feeding.
- C. Aspirate stomach contents.
- D. Check serum glucose level.
