In drowning with cardiac arrest, which action is emphasized?

• A. Ventilations
• B. Defibrillation first
• C. Suctioning only
• D. Remove wet clothing

Answer: (A)

The key idea is that drowning causes a problem with oxygen delivery, so restoring ventilation is the priority. In drowning-related cardiac arrest, the body’s first failing factor is hypoxia, not a primary electrical issue of the heart. Providing rescue breaths and supporting ventilation helps oxygen reach the lungs and circulate to the brain and heart, making high-quality ventilations the most important action. Defibrillation would only be the focus if a shockable rhythm is present, but the typical drowning arrest is driven by lack of oxygen, so ventilation takes precedence. Suctioning alone or removing wet clothing don’t address the core issue of oxygen deprivation, though they can be supportive; the main lifesaving emphasis is on delivering effective ventilations as part of CPR.
