Term 1 of 84
Holding your breath while ascending can lead to:
a rupture of the tiny air sacks in the lungs, known as alveoli.
A lung overpressure (overexpansion) injury.
Arterial gas embolism (AGE).
Headache and nausea.
Pain in the joints.
Tingling, numbness and paralysis.
They are not well suited for colder-water diving, They are not well suited for entries from
rocky shores.
Communicate information that hand signals cannot or
temporarily record dive data for later transfer to a log book.
Term 2 of 84
Among the key points in using your BC to help maintain neutral buoyancy under water:
Depth and time limits.
Planned activity.
Procedure to follow if separated.
To be successful in maintaining neutral buoyancy, you must be: aware of changes in depth;
and, anticipate the need to add or vent air from your BC by keeping a hand on the inflator
-Both divers use their right hands to hold on to the other's forearm or BC shoulder strap.
-Both divers use their left hands to grasp their BC's deflation mechanism to control rate of
ascent.
-Both divers maintain eye contact with one another, but offset themselves slightly so as not
to kick the other's fins.
The decreasing pressure may allow your regulator to function, even if it could not do so at
depth
,Term 3 of 84
The minimum information most dive computers provide you with while in Dive mode include:
Dive site location, weather conditions, equipment checklist.
Total air supply, time spent on the surface, water temperature readings.
Current and maximum dive depth, Actual bottom time, Decompression status (no-deco limit
or required deco).
Dive buddy status, underwater visibility, surface current strength.
Term 4 of 84
Always dive within the limits of your:
Lean Towards Your Right And Dip Your Right Shoulder.
Color, Odor, Taste
Training.
Equipment.
Experience.
Breathe Slowly And Deeply.
Term 5 of 84
What should you and your buddy do if separated during a dive?
Immediately start their prearranged plan for finding each other.
Surface and wait for your buddy to find you.

Continue diving until you see your buddy again.
, Term 6 of 84
Which of the following is among the most effective means of relieving a leg cramp once it has
occurred?
Grasp the fin tip of the affected leg and pull towards you while straightening the leg. This
stretches the calf muscle.
Kick harder with the other leg to relieve the cramp.
Slow down and switch to a different style of kick.
Change your fins to a different style.
Term 7 of 84
To minimize the risk of a lung overpressure injury during an independent emergency ascent:
You must inhale deeply before ascending.
You can breathe normally without concern.
You should hold your breath until you reach the surface.
You must be exhaling continuously any time you cannot inhale.
Term 8 of 84
The most accurate place to conduct a weight check is:
On the surface before entering the water.
While ascending rapidly to the surface.
At the beginning of the dive.
At safety-stop depth, at the end of the dive.
