Holding your breathe while scuba diving...
is extremely dangerous
allows you to stay under water longer
causes you to become less bouyant
is often encouraged by dive masters
The term used for this piece of equipment is
The Second Stage
The Pressure Breather
The Air Source
The Breathing Apparatus
BCD stands for
See the NOAA Diver's Manual or PADI's Open Water Dive Manual if clarification is needed.
bouyancy control device

As you descend, you consume air from your scuba tank
slower
faster
the same
When the hand moves side to side, the following hand signal means...
Out of Air
Watch Me
Come Here
Danger
What percent of oxygen and nitrogen are in a standard scuba tank?
50% oxygen, 49% nitrogen, 1% other
21% oxygen, 78% nitrogen, 1% other
68% oxygen, 31% nitrogen, 1% other
38% oxygen, 61% nitrogen, 1% other
A Thermocline...
Is a gradual change of water temperature
Is an abrupt change of water temperature
Is an underwater drinking device used to help stay hydrated
Is an abrupt change of water pressure
Water absorbs heat faster than air
True
False
One reason Buoyancy control is important is because divers need to control their rate of ascent and decent in the water
True
False
If a diver becomes unresponsive underwater, one should
bring the diver immediately to the surface
remove the diver's tank
supply the diver with an alternative air supply
remove the diver's weights
Nitrogen Narcosis...
is similar to alcohol intoxication
starts to occur at around 33 feet
is caused by a lack of nitrogen in a diver's blood stream
starts to occur after approximately 30 minutes of diving
Underwater pressure doubles every 10 meters while diving
Pressure doubles the first 10 meters, and then doubles again at 30 meters, and so on.
True
False
One reason a depth gauge is important is because...
It's easy to get lost under water
Your depth dictates how long you can stay under water
at night, it is difficult to calculate your depth
It notifies you when you are close to running out of air
SCUBA stands for "self contained underwater breathing apparatus"
True
False
Underwater, items you see will appear
reduced by 22%
reduced by 33%
magnified by 22%
magnified by 33%
Decompression Sickness...
may occur if a diver ascends too quickly from a dive
may occur if a diver does not perform decompression stops on a long dive
may lead to death
all the above
The following hand signal means...
Distress, Help
Out of air
Go that way
Come here
An object is less buoyant in ______ than it is in ______
fresh water, salt water
salt water, fresh water
A squeeze is a ...
pressure imbalance where the outside of an object is greater than the inside of an object
pressure imbalance where the inside of an object is greater than the outside of an object
hand signal often used in diving
form of diving without a tank
Comments
I got 100%!!
good test i got a 96!!!!
Question 18 - The correct answer should be False. The pressure doesn't double every 10m but increase by 1 atm. So the pressure only double on the 1st 10m (1atm at 0m -> 2 atm at 10m).
The above test is about passing the Padi training tests, if you answear differrent to what they have in the manuals and they are exspecting at the time of a test then you fail, regardless of what realitys are or what anyone else has to says on the matter. So anyone reading this discusion, consult your Padi teacher or manual if you are uncertain.
remember, Life is never black and white, unless it's an exam!
The dangers of NOT bringing a diver to the surface would far out weigh actually bringing him there. Normal rec. divers should not be having a problem with O2 tox. because for O2 to become toxic would take depths far below 130 ft., what they should be diving at. Even if using Nitrox, the chances of O2 tox. would be smaller than the other problems the diver is most likely facing. If you for a fact KNOW it is O2 tox., then you should treat it accordingly IF possible. But in most cases getting the diver to the surface is priority number one. And about the comment on not being able to surface yourself safely, well if you're following no dec. diving, then you should ALWAYS be able to ascend to the surface at ANY point in your dive. So this should not be a problem.
I am diver certified and all of the correct answers in this test were accurate if you disagree with something there is an explanation in the PADI Open water diver manual
No. 19 - If a diver is unresponsive it could be due to a number of factors. E.G. O2 Toxicity. Bringing him to the surface would exacerbate the problem. One should give him another source of breathing a weaker mix, stabilise the diver (let any convulsion pass) then take him to the surface.
Please edit that question.
on number 18 you should include the depth in feet as well as meters
I disagree with number 19 - "bring the diver immediately to the surface." Depending on the situation, you may not be able to safely ascend immediately to the surface yourself. I was taught early on that we don't want to create a second victim - your own safety has to come first.
Just food for thought
