The nurse caring for a newborn on a ventilator for respiratory distress syndrome (RDS) informs the parents that the newborn is improving. Which of the following supports the nurse's assessment?
 
  1. Increased PCO2
  2. Increased urination
  3. Decreased urine output
  4. Increased pulmonary vascular resistance

Explanation:
1. Increased PCO2 results from alveolar hypoventilation.
2. In babies with respiratory distress syndrome (RDS) who are on ventilators, increased urination may be an early clue that the baby's condition is improving. As fluid moves out of the lungs into the bloodstream, alveoli open, and kidney perfusion increases; this results in increased voiding.
3. As fluid moves out of the lungs and into the bloodstream, alveoli open, and kidney perfusion increases, thereby increasing urine output.
4. Pulmonary vascular resistance increases with hypoxia.
