Answer to Question 1

ANS: B
Instead of titrating levels of CPAP, the flow rate is incrementally adjusted; however, the amount of positive pressure that the high-flow nasal cannula potentially produces cannot be measured and inadvertent high levels may occur, particularly if the nasal cannula fits snugly in the nares.

Answer to Question 2

ANS: B
With large infants and children, pressures in the 80 to 100 mm Hg range are generally safe and effective.
