Basic Life Support (BLS) Practice Exam

When drowning is suspected, what is advised before starting CPR?

1. Start CPR immediately

2. Check for a pulse

3. Deliver 2 initial ventilations

4. Administer oxygen

The correct answer is: Deliver 2 initial ventilations

When drowning is suspected, delivering two initial ventilations before starting CPR is advised because it addresses the primary issue at hand: restoring oxygen to the victim's lungs. In drowning scenarios, the primary concern is often hypoxia, which occurs due to a lack of oxygen and the presence of water in the airway. By providing two initial ventilations, you can help expel any water from the lungs and provide oxygen to the victim, which is crucial in the early stages of resuscitation. This action is prioritized to increase the chances of survival, as the victim may have a limited time before irreversible brain damage occurs due to oxygen deprivation. After these initial ventilations are given, if there is no pulse or signs of circulation, CPR should then be performed with an emphasis on high-quality chest compressions and ventilations following the standard BLS protocol.
