True or False: Symptoms of a POIS typically arise suddenly and can occur minutes after surfacing.

• A. True
• B. False
• C. Only in severe cases
• D. They occur gradually

Answer: (A)

The statement is true because symptoms of Post-Operational Immersion Syndrome (POIS) indeed tend to manifest suddenly and can appear just minutes after a diver surfaces from a dive. This syndrome is typically associated with changes in pressure when resurfacing, which can result in a rapid onset of symptoms. Divers may experience a variety of symptoms, including disorientation, headache, and other neurological effects shortly after exiting the water. The sudden onset is a notable characteristic of POIS, distinguishing it from conditions that exhibit gradual symptom development.
