Answer to Question 1

ANS: A
Carbon dioxide rebreathing can occur if the oxygen flow to a simple or nonrebreathing mask is not sufficient to wash out the patient's exhaled gases. The flow of oxygen to a reservoir mask determines the FIO2, as do the patient's breathing pattern and the presence or absence of a reser-voir bag. Those masks with a reservoir bag will have a higher FIO2 than those without a reservoir bag.

Answer to Question 2

ANS: B
A typical partial rebreathing mask has a reservoir bag with a volume capacity of 300 to 500 mL.
