What signs should the nurse expect when a pneumothorax occurs in an infant on mechanical ventilation?
 
  a. Tachycardia
  b. Clear, distinct heart tones
  c. Widened pulse pressure
  d. Abrupt duskiness or cyanosis

Question 2

A preterm infant with respiratory distress syndrome is receiving inhaled nitric oxide (NO). What is the reason for administering the inhaled nitric oxide?
 
  a. To mature the lungs
  b. To deliver a level of oxygen that is safe
  c. To increase the removal of pulmonary debris such as meconium
  d. To reduce pulmonary vasoconstriction and pulmonary hypertension

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.
