Answer to Question 1

ANS: B
The jaw thrust is used mainly by trained clinicians when spinal neck injuries are suspected and is no longer recommended by the American Heart Association for lay rescuers (Figure 37-7).

Answer to Question 2

ANS: B
Exhaled air provides approximately 16 O2, which is sufficient to achieve an arterial O2 tension (PaO2) of between 50 and 60 mm Hg.
