Going to altitude after diving may be a problem because
a) lower pressure can increase DCS risk
b) higher pressure can increase DCS risk
c) lower pressure can increase oxygen problems
d) higher pressure can increase oxygen problems - CORRECT ANSWER -a) lower
pressure can increase DCS risk
The difference between flying after diving and altitude diving is that when flying
after diving, I go to altitude after a dive, and in altitude diving, I begin and end
with a dive at altitude.
TRUE or FALSE? - CORRECT ANSWER -True
My buddy and I have made two no stop dives a day for the last two days. Based on
current recommendations, we should wait at least _____ after our last dive before
flying.
A) 6 hours
B) 12 hours
C) 18 hours
D) 24 hours - CORRECT ANSWER -C) 18 hours
Cold and/or strenuous dives may be a problem with respect to DCS risk because
, A) I may end the dives with more dissolved nitrogen than calculated by dive
computer or tables
B) It is easier to ascend too fast when I make a cold/strenuous dive
C) Cool water can shut down my computer - CORRECT ANSWER -A) I may end the
dives with more dissolved nitrogen than calculated by dive computer or tables
If I'm cold or exert myself strenuously during a dive, I should
A) not make the safety stop
B) be even more conservative - CORRECT ANSWER -B) be even more conservative
Using the RDP Table or eRDPML, I should calculate a cold or strenuous dive as
A) 4 meters/10 feet shallower than the actual depth
B) 4 meters/10 feet deeper than the actual depth
C) having no surface interval
D) requiring emergency decompression - CORRECT ANSWER -B) 4 meters/10 feet
deeper than the actual depth
I would find a minimum surface interval when, after a dive, I want to know how
long the _____ would be.
A) no stop time and depth for the next dive
B) time at the surface - CORRECT ANSWER -B) time at the surface
One way to find a minimum surface interval with a computer is to periodically
check the no stop times for the depth you want, between dives.
TRUE or FALSE? - CORRECT ANSWER -TRUE
