Answer to Question 1

ANS: D
The early signs of a pneumothorax in an infant on mechanical ventilations include the abrupt onset of duskiness or cyanosis. Tachypnea is the presenting sign. Usually the heart rate is decreased. The heart sounds usually become muffled, diminished, or shifted. The pulse pressure decreases in pneumothorax.

Answer to Question 2

ANS: D
NO is used for infants with conditions such as meconium aspiration syndrome, pneumonia, sepsis, and congenital diaphragmatic hernia. Most infants with these disorders do have mature lungs. NO is not oxygen. Inhaled NO is beneficial for infants with meconium aspiration syndrome, but it does not work by removing debris. Inhaled NO is a significant treatment for infants with persistent pulmonary hypertension, pulmonary vasoconstriction, and subsequent acidosis and severe hypoxia. When inhaled into the lungs, it causes smooth muscle relaxation and reduction of pulmonary vasoconstriction and subsequent pulmonary hypertension.
