Basic Life Support (BLS) Practice Exam

Which of the following best describes the actions to take when initial attempts to clear a choking infant's airway fail?

1. Switch to back blows only

2. Continue with a combination of rescue efforts

3. Move to mouth-to-mouth resuscitation

4. Call for additional help immediately

The correct answer is: Continue with a combination of rescue efforts

In situations where initial attempts to clear a choking infant's airway are unsuccessful, continuing with a combination of rescue efforts is essential. The recommended approach is to alternate between back blows and chest thrusts until the obstruction is relieved or the infant becomes unresponsive. This method allows for the application of different physical maneuvers that can more effectively dislodge the object blocking the airway. Utilizing both techniques—back blows to create pressure and chest thrusts to provide deeper force—optimizes the chance of successful airway clearance and is supported by guidelines set by organizations like the American Heart Association. This multifaceted approach is crucial because choking can progress rapidly, and maintaining a clear airway is vital for the infant’s survival. In contrast, solely relying on back blows or moving directly to mouth-to-mouth resuscitation would not address the immediate need to clear the object blocking the airway. Furthermore, calling for additional help is important in a critical situation, but it should not replace ongoing rescue efforts, as seconds can make a significant difference in a choking scenario.
