Correct Answer is C

Explanation

A. Be monitored for respiratory rate: Important for ongoing assessment but not directly related to the deflation process.
B. Have the cuff pressure checked: Necessary during care but not immediately before deflation.
C. Have the pharynx suctioned: Suctioning clears secretions that could be aspirated when the cuff is deflated.
D. Be administered extra oxygen: Beneficial but not a direct prerequisite for cuff deflation.

A. Assist the guest to the floor and begin mouth-to-mouth resuscitation. B. Slap the guest on the back several times. C. Perform the Heimlich maneuver on the guest. D. Observe the guest before taking further action.

Correct Answer is C

Explanation

A. Assist the guest to the floor and begin mouth-to-mouth resuscitation: The airway is still obstructed, and rescue breathing is not effective until the obstruction is cleared.
B. Slap the guest on the back several times: Back slaps are not recommended for adults with complete airway obstruction as they may worsen the blockage.
C. Perform the Heimlich maneuver on the guest: Grasping the throat and inability to talk indicate a complete airway obstruction, requiring immediate abdominal thrusts (Heimlich maneuver) to clear the airway.
D. Observe the guest before taking further action: Delaying intervention in the presence of complete obstruction can lead to respiratory arrest. Immediate action is required.
