NAUI SCUBA DIVER ACTUAL
EXAMINATION 2026 QUESTIONS WITH
100% CORRECT ANSWERS GRADED A+
⫸ When buying or renting equipment for diving, the most important
consideration is: Answer: its fit on your body
⫸ ______ is a worldwide network of hyperbaric chambers and diving
physicians. Answer: Divers alert network (DAN)
⫸ If you are diving wearing an exposure suit, you should _____ to
safely control buoyancy as you descend. Answer: add air to your
buoyancy device.
⫸ A depth that is equivalent to one atmosphere in the ocean is
equivalent to _____ in sea water and _____ in fresh water. Answer: 10m
(33ft) ; 10.4m (34ft)
⫸ The minimum surface interval to avoid decompression after a dive to
88ft for 18 minutes, followed by a dive to 78ft for 23 minutes is...
Answer: 4hr and 49minutes
⫸ Diving equipment should be: Answer: rinsed thoroughly, dried and
stored in a cool place.
, ⫸ To relieve a cramp in the calf: Answer: Bend the toe of the fin toward
the knee to stretch the muscle.
⫸ Immediately upon reaching the dive site, you should: Answer:
Observe conditions
⫸ According to the NAUI dive tables, dives to less than 6m (20ft):
Answer: Are considered as 6m (20 foot) dives.
⫸ Which gas law best explains diving medical problems such as ear and
sinus squeeze? Answer: Boyles law
⫸ Explain Boyles Law: Answer: - Suppose we had a balloon measuring
one cubic foot at the surface of the water. This balloon is under 1 ATM
(14.7psi) of pressure.
- If we push the balloon underwater and take it to a depth of 33 feet, it is
now under 2 ATM of pressure (29.4lb) - 1 atm of pressure from the air
plus 1 ATM of pressure from the water.
- Boyle's Law then tells us that since we have twice the absolute
pressure, the volume of the balloon will be decreased to one half.
- It follow then, that taking the balloon to 66 feet, the pressure would
compress the balloon to one third its original size, 99 feet would make it
1/4 etc.
⫸ Which of the following will help prevent seasickness? Answer: Settle
yourself at a midway point of the boat.
