Water absorbs heat faster than air

True False

BCD stands for

See the NOAA Diver's Manual or PADI's Open Water Dive Manual if clarification is needed. bouyancy control device breathing control device breathing capacity diagram boat compass diving

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

When the hand moves side to side, the following hand signal means...

Out of Air Watch Me Come Here Danger

An object is less buoyant in ______ than it is in ______

fresh water, salt water salt water, fresh water

a

The following hand signal means...

Distress, Help Out of air Go that way Come here

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

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

One reason Buoyancy control is important is because divers need to control their rate of ascent and decent in the water

True False

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

Comments

uhhh...this test suks...not real test... 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
