PADI Emergency & Rescue Procedures 3

Question 1

Which symptom is MOST associated with arterial gas embolism (AGE) in a diver?

Accepted Answer

Sudden loss of consciousness or neurological symptoms at or near the surface

Answer

AGE typically presents with sudden, severe neurological symptoms such as unconsciousness or stroke-like signs occurring at or immediately after surfacing.

Question 2

What is the recommended position for transporting a diver suspected of decompression illness (DCI)?

Accepted Answer

Lying flat (supine) and kept still

Answer

Injured divers with DCI should be kept lying flat to avoid bubble migration and kept still to minimize exertion.

Question 3

Why is 100% oxygen administered to a suspected decompression illness victim?

Accepted Answer

It reduces nitrogen bubble size by increasing the diffusion gradient

Answer

Breathing 100% oxygen creates a large gradient that accelerates the off-gassing of nitrogen, helping to shrink bubbles causing DCI.

Question 4

During a rescue, you notice a diver floating face-down and unresponsive. After rolling them face-up, what is your FIRST assessment?

Accepted Answer

Check for breathing

Answer

After rolling the diver face-up and opening the airway, immediately check for breathing as the first assessment step.

Question 5

What does the acronym STOP represent in diver stress management?

Accepted Answer

Stop, Think, Orient, Plan

Answer

STOP (Stop, Think, Orient, Plan) is a cognitive tool divers use to interrupt panic and make rational decisions underwater.
