A. Is performing a safety stop
B. Starts ascending
C. Is performing a decompression stop
D. Starts descending - ANSWER--B. Starts ascending
On desaturation, the inert gas diffuses from the tissues into the
bloodstream, from the blood into the alveolar air, and then:
A. Back into the blood stream
B. Out of the body with each exhalation
C. Through the lung tissues into the mediastinum
D. Into the sensor of the dive computer - ANSWER--B. Out of the body with
each exhalation
Multi-level dives, in general, are those where:
A. All of the answers are correct
B. Divers spend time at progressively deeper depths during the dive, which
allows extended bottom time
C. Divers spend time at progressively shallower depths during the
dive, which allows extended bottom time
D. Divers spend time at progressively shallower depths during the dive,
which allows less bottom time - ANSWER--C. Divers spend time at
progressively shallower depths during the dive, which allows extended
bottom time

should be

intermediate pressure
D. Reduce high-pressure air coming from the cylinder to an increased
intermediate pressure - ANSWER--C. Reduce high-pressure air coming
from the cylinder to a consistent intermediate pressure

compensators have:
A. A harness
B. An inflator
C. An integrated weight system
D. Pockets - ANSWER--C. An integrated weight system
Once you have determined weight requirements, you must make certain
that it is:
A. Colorful
B. All fixed at one place
C. Heavy
D. Properly distributed - ANSWER--D. Properly distributed
