Answer to Question 1

C
Feedback:
When blood Po2 levels rise to higher than 100 mmHg, the risk of retinopathy of prematurity increases. All preterm infants who receive oxygen must have blood oxygen levels monitored by pulse oximeter, transcutaneous oxygen saturation, or blood gas monitoring so the blood Po2 level can be kept within normal limits. Oxygenation at 40 mmHg or 50 mmHg is not sufficient for the infant. Oxygenation at 180 mmHg is too high and can predispose the infant to develop retinopathy of oxygenation.

Answer to Question 2

B, D, F
Feedback:
Signs and symptoms of withdrawal, or neonatal abstinence syndrome, include: irritability, hypertonicity, excessive and often high-pitched crying, vomiting, diarrhea, feeding disturbances, respiratory distress, disturbed sleeping, excessive sneezing and yawning, nasal stuffiness, diaphoresis, fever, poor sucking, tremors, and seizures.
