PADI Emergency Procedures & Rescue Techniques — Questions and Answers

Question 1: What is the first step in assisting a distressed diver?

Panic and shout
Approach calmly and assess (Correct answer)
Ignore and continue dive
Immediately surface alone

Correct answer: Approach calmly and assess

The first and most crucial step in assisting a distressed diver is to remain calm and approach them cautiously. This allows the rescuer to assess the situation without escalating the diver's panic or putting themselves at risk. A calm approach enables a more effective evaluation of the problem and the appropriate response.

Question 2: What is the recommended rescue technique for an unresponsive diver at the surface?

Leave diver and call for help
Controlled tow and emergency response (Correct answer)
Try to swim quickly to shore
Ignore and finish dive

Correct answer: Controlled tow and emergency response

For an unresponsive diver at the surface, the recommended rescue technique involves establishing positive buoyancy for both the diver and rescuer, then performing a controlled tow to a safe location. Simultaneously, the rescuer should initiate an emergency response, which includes calling for help, administering rescue breaths if needed, and preparing for medical assistance. This systematic approach maximizes the chances of a positive outcome.

Question 3: When should emergency oxygen be administered to a diver?

Only in hospital
Signs of decompression sickness or distress (Correct answer)
Never
Only if unconscious

Correct answer: Signs of decompression sickness or distress

Whenever signs of decompression sickness or breathing difficulty appear.

Question 4: What is the role of the emergency action plan in diving?

To confuse divers
Provide emergency procedures (Correct answer)
Avoid emergencies
Schedule dives

Correct answer: Provide emergency procedures

An Emergency Action Plan (EAP) is a pre-established set of procedures designed to guide divers and dive operators in responding to various emergencies. It outlines steps for contacting emergency services, administering first aid, and managing specific incidents like lost divers or dive injuries. Having a clear EAP ensures a swift, organized, and effective response when an emergency occurs.

Question 5: How should a diver signal for help underwater?

Shouting
Tap tank or use signal device (Correct answer)
Swimming away
Ignoring problem

Correct answer: Tap tank or use signal device

Underwater, shouting is ineffective due to water density. Divers signal for help by tapping their tank with a hard object (like a knife or tank banger) to create an audible sound that travels well underwater, or by using visual signal devices like whistles (on the surface) or strobes. These methods effectively alert buddies or dive leaders to a problem, allowing for a timely response.

Question 6: What is the primary goal of rescue breathing?

Start CPR
Provide oxygen until help arrives (Correct answer)
Stop bleeding
Control shock

Correct answer: Provide oxygen until help arrives

The primary goal of rescue breathing, in the context of a diving emergency, is to provide oxygen to a non-breathing diver until professional medical help or advanced life support arrives. While CPR may be necessary if there's no pulse, rescue breathing alone focuses on oxygenation to prevent further brain damage and maintain vital functions. It's a crucial step in the chain of survival.

Question 7: Why is maintaining buoyancy important during a rescue?

To swim faster
Prevent uncontrolled sinking (Correct answer)
Avoid contact
Signal for help

Correct answer: Prevent uncontrolled sinking

Maintaining proper buoyancy is crucial during a rescue scenario to prevent both the rescuer and the distressed diver from sinking uncontrollably. Establishing positive buoyancy allows the rescuer to manage the situation more effectively, keep the diver at the surface, and conserve energy. It ensures control and stability, which are vital for a successful rescue.

Question 8: What is the best practice after surfacing a rescued diver?

Remove equipment quickly
Remove equipment carefully and monitor (Correct answer)
Ignore diver’s condition
Start dive again

Correct answer: Remove equipment carefully and monitor

After surfacing a rescued diver, it is essential to remove their equipment carefully to avoid causing further injury or discomfort, especially if they are injured or unconscious. Simultaneously, the rescuer must continuously monitor the diver's condition, checking for breathing, pulse, and signs of injury or decompression sickness, while awaiting professional medical assistance. This ensures ongoing care and assessment.

Question 9: When should a diver call emergency medical services (EMS)?

After finishing dive
Immediately after serious injury (Correct answer)
Only if unconscious
Never

Correct answer: Immediately after serious injury

Emergency Medical Services (EMS) should be called immediately whenever a diver sustains a serious injury, exhibits signs of decompression sickness, or is unresponsive. Prompt activation of EMS ensures that professional medical personnel are en route to provide advanced care, transport the diver to an appropriate medical facility, and manage potentially life-threatening conditions. Delaying this call can significantly worsen outcomes.
