1. What is the most important rule in scuba diving?

Never dive alone.

Always perform a predive safety check.

Establish positive buoyancy and relax when at the surface.

Breathe continuously and never hold your breath.

2. During a descent, I begin to feel pressure on my ears. I should

equalize early and often.

go down as quickly as I can.

blow air into my mask through my nose.

always descend head first.

3. Diving when I have a cold or allergies may cause

unconsciousness without warning.

seasickness.

difficulty equalizing.

rapid air use.

4. As I descend, I have trouble equalizing my ears. After signaling my buddy, I should ________________. If that doesn't work, I should abort the dive.

stop and equalize forcefully

stop and equalize for a prolonged period

continue slightly deeper and try again

stop, ascend slightly and try again

5. I need to make myself buoyant on the surface, but my BCD doesn't seem to hold air. The correct response would be to

quickly release my weights.

orally inflate my BCD.

kick harder.

climb onto my buddy.

6. My buddy swims faster than me and I find myself swimming too hard to keep up. I begin breathing hard and feel like I can't get enough air. I should get my buddy's attention, then

ascend to the surface.

stop and rest, holding on to something if possible.

signal my buddy to share air.

press the purge button on my regulator.

7. During a dive, I begin to shiver. At first it comes and goes, but then I begin to shiver uncontrollably. The appropriate action would be to

plan to wear more exposure protection on the next dive.

swim faster or exercise to warm up.

end the dive immediately, dry off and seek warmth.

keep my arms at my sides and hands clasped.

8. My buddy and I are headed to the boat's mooring line, where we plan to ascend, make a safety stop and exit the water. However, before we get there I reach the pressure at which we planned to head up (ascent pressure). Under most circumstances, the correct action would be to

use my reserve to reach the mooring line.

signal my buddy to begin our ascent where we are.

hold my breath or breathe shallow until reaching the line.

share air with my buddy to reach the line.

9. Diving with two buddies, I notice that one isn't in sight. I signal to the other. At that point, the general rule is to

surface together, wait a minute and then go back down together if our buddy doesn't come up.

search together underwater for a minute and reunite on the surface if not found.

split up and search for five minutes.

continue the dive and wait for our buddy to find us.

10. My buddy and I observe a mild current at the dive site. Generally, when we start our dive we should swim

with the current.

is trying to protect itself.

is aggressive.

mistakes a diver for a rival mate.

mistakes a diver for food.

12. Surfacing from a dive, my buddy and I find a moderate current carrying us away from the boat. We miss the trail line. What should we do?

Make ourselves buoyant, signal for help, rest and wait for the boat to pick us up.

Descend and try to swim against the current near the bottom.

Make ourselves buoyant and swim against the current.

Swim back to the boat, against the current, just below the surface.

13. While boat diving, I'm at the surface waiting for my buddy to enter. Unexpectedly, my fin comes off my foot, making it difficult for me to maintain my position. My first response should be to

establish positive buoyancy.

descend to chase it.

take my mask off.

climb the boat ladder.

14. My buddy is within arm's reach and gives me the out-of-air signal. I should

provide my alternate air source, then ascend together in a controlled manner.

signal for my buddy to make a controlled emergency swimming ascent (CESA – swim up to the surface saying the "ahhh" sound).

drop my buddy's weights and ascend together.

watch to see what my buddy does next.

15. The risk of decompression sickness (DCS) is thought to be higher if a diver

dives in poor visibility, strong moving water and rough seas.

is tired, cold, sick, thirsty or overweight.

uses equipment that is not working properly.

uses dive tables instead of a computer.

16. To reduce the risk of decompression sickness, my buddy and I

have our cylinders filled with 100 percent oxygen.

almost (but not quite) hold every other breath.

make a safety stop at 5 metres/15 feet at the end of each dive.

ascend to a shallower depth if feeling intoxicated or confused.

17. I've just invested in a new dive computer. The first thing I should do with it is

set the date and time.

read the manufacturer's instructions.

take it on a test dive.

switch it to fresh or salt water.

18. I am headed out of town on a commercial flight, but I want to make two dives. Based on the current recommendations, what is the minimum time that I should allow after the second dive before getting on the plane?

48 hours

24 hours

18 hours

12 hours

19. My buddy and I are swimming at 18 metres/60 feet. I check my dive computer and discover that it is completely dead, and I'm not using a backup computer. The correct action is to

continue the dive based on my buddy's computer.

ascend immediately, make a safety stop and surface.

hit the computer sharply with my palm.

press the computer's reset button.

20. Just before we're supposed to ascend, my buddy's dive watch falls off. After locating it, we find we've accidentally exceeded our computers' no stop limits. Overstaying our time to look for it was a bad decision, but now we should

surface immediately, breathe oxygen and report our condition to the divemaster.

make a safety stop for three minutes at 5 m/15 ft.

decompress according to the computers' instructions.

make a normal ascent.

21. As Advanced Open Water Divers, my buddy and I are diving at 30 metres/100 feet. I feel a bit "drunk" and have trouble reading my dive computer. It's likely that I'm experiencing

oxygen toxicity.
