Answer :
Final answer:
For an unresponsive adult with an airway obstruction, a lay rescuer should not perform CPR, straddle the knees, or blow in the nose. Instead, they should conduct the Heimlich maneuver to attempt to clear the obstruction and call for emergency help if needed.
Explanation:
Care for an Unresponsive Adult with Airway Obstruction
When addressing an unresponsive adult with an airway obstruction, it is critical to act quickly and properly to clear the airway. The appropriate action to take in this scenario is not to perform CPR unless the individual is in cardiac arrest, but rather to focus on relieving the obstruction.
- Do not perform CPR unless there is a separate need for it (e.g., the victim is not breathing).
- A lay rescuer should avoid straddling the victim's knees, as this does not contribute to resolving the airway obstruction.
- Blowing in the nose is ineffective and inappropriate, as it does not aid in dislodging any object in the airway.
If the obstruction is evident, the lay rescuer should attempt the Heimlich maneuver or abdominal thrusts to clear the airway. If unsuccessful, emergency medical services should be contacted immediately.
