True or False: A diver bolts for the surface. Assisting the diver requires you to stop the person's ascent.

False

True or False: While diving on a wreck, your buddy gets some monofilament fishing line wrapped around the cylinder valve and can't get to it. Your first step would be to have your buddy turn to see if that releases it.

False

You and your buddy have surfaced after a long dive in cool water. You wore a dry suit, but your buddy was in a thin wet suit. The air temperature is brisk, and your buddy was standing around in the wet suit rather than changing into warm dry clothes. Your buddy is now shivering uncontrollably, and complains of numb fingertips and no grip strength. Your buddy's lips, fingers and toes appear bluish. You should begin first aid for

Hypothermia

Timely BLS is important because it attempts to keep the brain supplied with oxygen. After ____________ minutes without oxygen brain damage is likely, and after ____________ minutes it is almost certain.

6; 10.

An emergency action plan is

The information you would need to manage an accident at a particular site.

True or False: A diver has had an accident in a cool climate. You and your buddies have gotten the diver ashore and are providing BLS and emergency oxygen. EMS is on the way. The diver is lying down, responsive and breathing, but in pain. You've gotten the wet suit off and put a blanket over the patient to help maintain body temperature. By enacting these steps, you've followed the procedures for treating shock in a diving emergency.

True

True or False: After too long in the hot sun wearing a dry suit, a diver is feeling very poorly. Once out of the suit, the diver isn't sweating and feels hot to the touch. You should call EMS and get the patient into cool water or apply cool wet towels.

True

True or False: When implementing a search for a missing diver, permit searches only by buddy teams within safe gas supply, no stop time and exposure limits. Have a way to recall searchers.
