NAUI Underwater Skills & Safety Procedures 5

Question 1

During a drift dive, divers should maintain contact with the group primarily by:

Accepted Answer

Staying within visual range and matching depth

Answer

In drift dives, all divers drift at the same speed with the current, so maintaining visual contact and consistent depth keeps the group together.

Question 2

What does the acronym 'STOP' stand for in the context of a diving emergency?

Accepted Answer

Stabilize, Think, Observe, Proceed

Answer

STOP (Stabilize, Think, Observe, Proceed) is a decision framework used to prevent panic and ensure rational action during diving emergencies.

Question 3

When a diver enters the water using a giant stride entry from a boat, what should they do immediately after surfacing?

Accepted Answer

Signal OK to the boat and clear the entry area

Answer

Signaling OK and clearing the entry area allows the next diver to enter safely without collision risk.

Question 4

A diver notices kelp wrapped around their leg during a dive. The safest response is to:

Accepted Answer

Stop movement, slowly and calmly untangle by hand

Answer

Calm, deliberate manual untangling prevents entanglement from worsening and conserves air, unlike kicking which can tighten the kelp.

Question 5

Which sign indicates a diver may be experiencing an arterial gas embolism (AGE) upon surfacing?

Accepted Answer

Immediate loss of consciousness or neurological symptoms at or shortly after surfacing

Answer

AGE occurs when air bubbles enter the bloodstream, typically causing immediate and severe neurological symptoms at or just after surfacing.
