What position is used to open the airway in an unconscious patient?
a. Neck extension
b. Neck flexion
c. Recovery position
d. Sniff position
ANS: D
With loss of consciousness, the head flexes forward, which can partially or completely obstruct the upper airway (Figure 9-41, A). Extension of the head and lower jaw into the "sniff" position alleviates this obstruction (Figure 9-41, C). Extension of the head moves the tongue away from the rear of the pharynx. This technique is used to maintain the airway in unconscious patients and facilitates placement of artificial airways.
