AHA BLS for Healthcare Providers Practice Test

The recommended compression to breath ratio during CPR for infants when only one rescuer is present is 30 compressions to 2 breaths. This approach aligns with the updated guidelines, which emphasize high-quality chest compressions along with effective ventilations for resuscitation. The 30:2 ratio allows for a balance between providing sufficient blood flow through compressions and delivering oxygen via breaths, ultimately improving the chances of survival for the infant.

In contrast, the 15:2 ratio is specifically used when there are two rescuers present, aiming to optimize the efficiency and effectiveness of the CPR process by allowing for a more rapid sequence of ventilations combined with chest compressions. Options that suggest a different ratio for a single rescuer or misidentified rescuer scenarios do not accurately reflect current BLS protocols. Moreover, the 20:2 ratio is not a recognized standard in BLS practices, further further emphasizing the importance of adhering to well-established guidelines for infant CPR.
