Question

Quizplus · Accepted Answer

The diver's symptoms are indicative of nitrogen narcosis, a condition that occurs when divers breathe compressed air at depth, leading to increased nitrogen levels in the blood. This can cause confusion and uncoordination, matching the diver's presentation. His blood sugar level is normal, ruling out hypoglycemia, and his SpO₂ is 98%, indicating he is not hypoxic. There is no specific information suggesting seizure activity.
