Answer to Question 1

ANS: C
Neonatal and pediatric patients have smaller lungs, higher airway resistance, lower lung compli-ance, less surface area for gas exchange, and lower cardiovascular reserve than do adults; all of these factors make them more vulnerable to rapid deterioration. Although neonates have high chest wall compliance, this is not the reason for their vulnerability to rapid deterioration. It is the reason for the presence of retractions when the WOB is elevated.

Answer to Question 2

ANS: B
The minimum acceptable pH for a premature or term newborn is 7.25. Values below that level are considered inadequate, especially when the PaCO2 is greater than 50 mm Hg.
