Answer 1

If you are unable to make a required decompression stop while diving, you should breathe pure oxygen, monitor for signs of decompression sickness, and avoid diving or flying for at least 24 hours.

Step-by-step explanation:

If you are unable to make a required decompression stop while diving, it is important to take certain steps to avoid decompression sickness (DCS). The correct course of action is to do all of the above:

1. Breathe pure oxygen for at least 30 minutes. This helps to flush out any dissolved gases in the blood and reduces the risk of DCS.
2. Monitor for signs and symptoms of decompression sickness for the next 24 hours. This includes symptoms such as joint pain, rashes, numbness, or difficulty in breathing.
3. Do not dive or fly for at least 24 hours. This allows the body time to recover and reduces the risk of exacerbating the condition.
