PADI Emergency Procedures & Rescue Techniques 5

Question 1

What is the maximum recommended depth at which in-water rescue breathing is practical?

Accepted Answer

At the surface only

Answer

In-water rescue breathing is performed only at the surface because effective mask-to-mouth ventilation is not practical underwater.

Question 2

A diver is displaying signs of nitrogen narcosis at 30 meters. What is the correct first response?

Accepted Answer

Ascend the diver to a shallower depth where symptoms resolve

Answer

Nitrogen narcosis resolves rapidly when the diver ascends to shallower water, making controlled ascent the immediate treatment.

Question 3

Which factor MOST increases the risk of a diver requiring rescue during a dive?

Accepted Answer

Diving beyond their training and experience level

Answer

Exceeding one's training and experience level is the leading human factor in dive accidents requiring rescue interventions.

Question 4

When should a rescuer stop performing in-water rescue breathing and transition to full CPR?

Accepted Answer

Once the victim is removed from the water and placed on a firm surface

Answer

Effective chest compressions require a firm, stable surface, so CPR begins only after the victim is removed from the water.

Question 5

A diver surfaces complaining of severe fatigue, skin rashes, and joint pain 12 hours after a repetitive dive day. What is the most likely diagnosis?

Accepted Answer

Decompression sickness (DCS)

Answer

Delayed onset of fatigue, skin rashes (cutis marmorata), and joint pain hours after diving are classic presentations of decompression sickness.
