Answer to Question 1

ANS: D
Transtracheal invasive airway insertion is a procedure that involves the surgical placement of a catheter through the airway and does not require extension of the neck. For nasopharyngeal air-way insertion, the head and neck do not need to be adjusted. The jaw thrust or chin lift is used if the neck is not able to be extended because of cervical spine injuries.

Answer to Question 2

ANS: B
The total flow from an air-entrainment mask will increase as the oxygen flow rate is increased. As long as the air:oxygen ratio is not changed, there will be no changes in the delivered FIO2.
