C. Exit the water when convenient, and swim rapidly to warm up. - ✔✔A. Exit the water
immediately, dry off, and seek warmth.
✔✔During a dive, my buddy and I have to swim hard because of an unexpected current.
If I were to begin to feel fatigued, have labored breathing, experience a feeling of
suffocation or air starvation, and perhaps feel like I may panic, I should:
A. Signal "up" and head to the surface.

buddy separation would be adequate. If during the dive I find I am with one buddy but
can't see the other, which of following applies?
A. This is buddy separation. Stay with the remaining buddy and search for no more than
a minute, then reunite on the surface.
B. This is buddy separation. Stay with the remaining buddy, return to where the missing
buddy was last seen, and wait.
C. This is buddy separation. The remaining buddy and I should split up and look for the
missing buddy.
D. This is not buddy separation for the remaining buddy and me. Stay with the

✔✔My buddy and I are planning a shore dive. We're descending onto a very gradual
slope that begins at 5 metres/15 feet, so our descent and ascent will be a gradual part
of swimming out and back underwater. We have similar cylinders filled to 200 bar/3000
psi. We plan:
- 50 bar/500 psi reserve
- 20 bar/300 psi for our safety trip
- To turn the dive when we've used one-third of the air available to use on the dive.
This means we should head back when either of our SPGs read:
A. 70 bar/800 psi.
B. 145 bar/1900 psi.
C. 157 bar/2270 psi.
D. 170 bar/2500 psi. - ✔✔C. 157 bar/2270 psi.
✔✔My fin strap comes loose (later I discover that I didn't buckle it properly) while
swimming at the surface in choppy waves. Which of the following habits would help me
as I handle this problem?
, A. Having my mask on and a mouthpiece in my mouth.
B. Having enough air in my BCD for adequate buoyancy.
C. Staying close to and signaling my buddy. - ✔✔A. Having my mask on and a
mouthpiece in my mouth.
and
B. Having enough air in my BCD for adequate buoyancy.
and
C. Staying close to and signaling my buddy.
✔✔I'm about the begin descent with my buddy. Which of the following steps should I
take before actually beginning my decent?
A. Equalize my ears.
B. Orient myself to something at the surface.
C. Check that my computer is active.
D. Confirm that my buddy is ready.
E. Add air to my BCD. - ✔✔B. Orient myself to something at the surface.
and
C. Check that my computer is active.
and
D. Confirm that my buddy is ready.
✔✔My buddies and I are wearing wet suits for exposure protection. As I descend, my
buoyancy will __________, so I should ___________ to control my buoyancy.
A. Remain constant, Do nothing.
B. Increase, Release air infrequently from my BCD in large amounts.
C. Increase, Release air frequently from my BCD in small amounts.
D. Decrease, Add air infrequently to my BCD in large amounts.
E. Decrease, Add air frequently to my BCD in small amounts. - ✔✔E. Decrease, Add air
frequently to my BCD in small amounts.
✔✔True or False: I should never descend or ascend without a reference that I can
follow or make contact with. - ✔✔True.
✔✔As a prudent, conservative diver, the following are normal parts of my ascents:
A. Ascending at 18 metres/60 feet per minute (or slower if specified by my computer).
B. Inflating my BCD to begin my ascent.
C. Stopping for 3 minutes at approximately 5 metres/15 feet.
D. Adjusting my buoyancy in small amounts frequently. - ✔✔A. Ascending at 18
metres/60 feet per minute (or slower if specified by my computer).
