PADI Dive Skills 5

Question 1

A diver is towing an unconscious diver at the surface. Which position is safest for the unconscious diver?

Accepted Answer

Face-up with the airway clear of the water

Answer

An unconscious diver must be kept face-up with the airway above the waterline to maintain an open airway and allow rescue breathing if needed.

Question 2

What is the correct response when a diver's BCD inflator hose becomes stuck in the inflate position and the BCD is over-inflating?

Accepted Answer

Disconnect the low-pressure inflator hose and vent the BCD orally or via the dump valves

Answer

Disconnecting the low-pressure inflator hose stops the source of inflation, and the diver can then vent excess air through dump valves or the oral inflator.

Question 3

Which condition most increases the risk of nitrogen narcosis affecting diver judgment?

Accepted Answer

Cold water, anxiety, or rapid descent to depth

Answer

Cold water, anxiety, fatigue, and rapid descent to depth all increase susceptibility to nitrogen narcosis and its effects on judgment.

Question 4

During a boat dive, a diver surfaces 100 meters from the vessel in choppy conditions. What is the recommended first action?

Accepted Answer

Inflate the BCD, establish positive buoyancy, and signal the boat using a surface marker or whistle

Answer

Establishing positive buoyancy by inflating the BCD is the priority, followed by signaling the boat using an SMB, whistle, or mirror.

Question 5

When practicing buoyant ascent skills, which action correctly describes the 'LPI hose up' technique during ascent?

Accepted Answer

Raising the LPI hose overhead and pressing the deflate button to vent expanding air

Answer

Holding the LPI hose overhead positions the BCD's highest point at the valve, allowing expanding air to vent efficiently during ascent.
