1Which towing technique allows a rescuer to cover a short distance most quickly while both divers remain in full scuba equipment?
Why: Because it keeps both arms free to swim, the tank-valve grip is the speediest way to close a short gap while gear is still on.
2What combination best describes being prepared with equipment for a rescue?
Why: True equipment readiness combines having appropriate gear, knowing how to operate it, and being able to improvise — no single element is sufficient on its own.
3Carlos pulls an unconscious diver from the water. Because the diver cannot verbally agree to treatment, Carlos relies on the assumption that she would want oxygen. What is this assumption called?
Why: Implied consent lets a rescuer treat someone who cannot communicate, based on the reasonable assumption that the person would agree to care such as oxygen if they were able to respond.
4Regarding the placement and appearance of an alternate air source, general diving consensus holds that it should
Why: The general consensus is that the alternate air source should be clearly identifiable, not concealed, relocated, or blended in with other gear.
5Which of these is NOT identified as a cause of shock arising from a diving incident?
Why: Decompression illness, marine-life injuries, and near drowning are all cited as causes of shock, while boat-deck sunburn is not among them.
6When an unresponsive, non-breathing diver is only a short swim (about three minutes or less) from the boat, what should the rescuer do?
Why: A short swim to the boat means rescue breaths should not be sacrificed for speed; both can be done together.
7A diver juggling too many jobs at once during a dive — checking gauges, navigating, and monitoring a buddy — is likely suffering from
Why: Having to perform several duties simultaneously is called task loading, and it is one of the recognized sources of psychological stress for divers.
8When a rescuer must tow a tired diver only a short distance while staying face to face and offering reassurance, the recommended technique is called the ____.
Why: The modified tired swimmer’s carry is the technique built for short tows with ongoing eye contact and reassurance.
9Which statement correctly identifies a benefit of an AED?
Why: This describes the AED's actual benefit: attempting to restore a normal heart rhythm before EMS arrives.
10Which treatment is NOT appropriate for a puncture wound from a venomous marine spine?
Why: A cold pack is the inappropriate option here, since these wounds are treated with warmth rather than cold.
11A power inflator that keeps adding air even after the diver releases the button is chiefly dangerous because it may cause
Why: Unstoppable inflation builds excess buoyancy over time, and the recognized primary hazard is losing control of ascent speed, not gas depletion or bladder damage.
12Rescuer Ana is about 10 minutes from the boat with an unresponsive, nonbreathing diver. After Ana's first rescue breaths, the diver's arms twitch. What is Ana's best course of action?
Why: The best course combines both required actions at once: continuing rescue breaths while towing the victim to the boat.
13What should a rescuer do with an unresponsive diver's regulator, found still in place, while ascending from underwater?
Why: The regulator should be held in place in the victim's mouth throughout the ascent if it is already there.
14Marco is writing a safety newsletter about scuba incidents. He wants to open with the single biggest driver of dive emergencies. Based on accident research, he should write that most incidents trace back to:
Why: The diver’s own poor judgment is identified as the most common cause of dive emergencies, ahead of gear failure, weather, or sudden illness.
15A weight belt and a pair of gloves are the items a rescuer will almost always need before swimming to help a responsive diver in trouble on the surface.
Why: Weights and gloves are not the essential gear; mask, fins, and snorkel are what a rescuer almost always wants for this kind of surface swim.
