Four main actions you should consider in giving first aid for diving accidents are:

• A. Maintain basic life support, call for help, treat for shock, deliver 100% oxygen
• B. Check air supply, document, notify authorities, survey damage
• C. Monitor vitals, provide water, rest, reassess
• D. Secure equipment, log dive, rinse gear, return to boat

Answer: (A)

In diving emergencies, the priorities are to preserve life, get professional help fast, and start treatment that can reduce the injury’s progression. The four actions shown align with that approach. Maintaining basic life support means securing the airway, ensuring breathing, and supporting circulation—be ready to perform CPR if needed. Calling for help brings in trained responders and ensures rapid transport to appropriate care. Treating for shock helps keep the diver’s blood flow adequate and their body warmed while waiting for advanced treatment. Delivering 100% oxygen as soon as possible is crucial because high-flow oxygen improves tissue oxygenation and helps reduce nitrogen bubbles in decompression illness or gas embolism, which are common diving emergencies. These steps together address the immediate life-saving needs and the specific dive-related pathologies that benefit from rapid high-concentration oxygen. The other options miss the core urgent actions: they include tasks that aren’t immediate life-saving measures in a diving accident or omit essential oxygen therapy and rapid access to professional care.
