Answer to Question 1

ANS: B
A partial rebreathing mask can deliver an FIO2 of 0.40 to 0.60 with oxygen flows of 6 to 8 L/min. The actual percentage of oxygen delivered is also influenced by the patient's ventilatory pattern.

Answer to Question 2

ANS: C
The two types of reservoir nasal cannulas are the mustache and the pendant. The high-flow nasal cannula can provide heated, humidified oxygen at flows varying between 5 and 40 L/min.
