Correct Answer: 1,2,3
Rationale 1: Most illicit drugs cross the placenta and can cause premature birth, low birth weight, birth defects, and withdrawal symptoms.
Rationale 2: Certain drugs can cause constriction of placental blood vessels, resulting in decreased nutrient exchange.
Rationale 3: Most illicit drugs cross the placenta and can cause premature birth, low birth weight, birth defects, and withdrawal symptoms.

Rationale 5: While withdrawal can cause irritability in infants born to drug addicts, the risk for irritability is not the reason for abstaining from drug use during pregnancy.
