1. regulator first stage, 2. regulator second stage, 3. alternate air source second stage, 4. low pressure inflator hose for the BCD, 5. instrument console/gauges/computer.
Unless there are laws that say differently, I should stay within _______ of my dive flag.
15 meters/ 50 feet
I make two dives in one day and am flying home on a commercial plane. I should wait until my computer says I can fly or ________ hours, whichever is longer.
18
As a new PADI Open Water Diver, the recommended maximum depth is ______________, or the actual depth I reached in training, if shallower. The maximum depth for all recreational scuba divers, even experienced divers, is ______________.
18 metres/60 feet / 40 metres/130 feet
If my cylinder of air lasts 60 minutes while I am at the surface breathing normally, assuming all else is the same, how long will it last at 20 metres/66 feet breathing normally?
20 minutes
If an object is neutrally buoyant (does not sink or float) in fresh water, the same object placed into salt water would
Float
If my ears or sinuses hurt while I am descending (going down), it usually means
I am feeling a squeeze and need to equalize
When diving at an altitude above 300 metres/1000 feet
I need to follow special procedures and may need to set my computer for the altitude.
If I'm diving in cold water or under strenuous conditions
I should add an extra safety margin and stay well within my computer's limits.
Which of the following is part of proper care for my scuba cylinder?
Keep some air in it
How often should I take my scuba cylinder to be visually inspected by my dive center?
Once a year
Choose the best answer for the signal shown from the choices provided. (guy making a "your" sign in sign language but its not sign language)
Stop, hold it, stay there
I blow up a balloon, tie it off, and take it to the bottom of the swimming pool. What will happen to the balloon and the air inside it?
The balloon will get smaller and the air inside the balloon will be more dense (molecules move closer together).
If I am not able to equalize (clear) my body air spaces, it may be because I have
a cold, allergy or another medical problem.
Divers who act foolishly at depth due to gas narcosis may start acting normally again if they
ascend (go up) to a shallower depth.
If my computer fails during a dive, I can use my backup computer to continue the dive. If I'm not wearing a backup, I should
ascend (go up), make a safety stop and end the dive
Although it shouldn't have happened, on a dive I fail to watch my SPG and run out of air. If my buddy is close by, my best option is to _______. Another option is to ________, if I'm in shallow water and the surface is closer than my buddy.
ascend using my buddy's alternate air source / make a controlled emergency swimming ascent
I turn a glass upside down, trap the air in it by putting it in water, and then I take the glass down to 10 metres/33 feet. The air space would
become half the size it was at the surface.
If I think I have decompression sickness I should
breathe 100 percent oxygen and contact emergency medical care.
As I descend (go down), my wet suit will
compress (feel thinner) from water pressure, and I will lose buoyancy and warmth.
Choose the best answer for the signal shown from the choices provided. (waving arms above head above water
distress, help
I feel a mild current at the start of my dive. How should I begin this dive?
dive against or into the current
I am likely to increase the risk of decompression sickness (DCS) if I
dive while tired, cold, sick, thirsty or injured.
When making computer assisted dives
each diver needs a personal computer.
I know I am properly weighted for diving if I
float at eye level while holding a normal breath of air and with an empty BCD.
If I accidentally exceed my computer's no stop limits, I should
follow the computer's instructions for decompression.
The difference between DIN valves and yoke valves is that DIN valves
have threaded openings to screw the regulator into
If my regulator begins to free flow (release air continuously) while underwater, I should
hold the regulator without sealing my mouth around the mouthpiece and "sip" the air I need as I ascend (go up).
Lung overexpansion injuries can be caused by
holding my breath while scuba diving.
I am most likely to become confused about which way is up or down _________.
in midwater
The best place for me to position an alternate air source is
in the triangle area formed by my chin and the lower corners of my rib cage.
It's important that I do not turn off a dive computer between dives because
it would lose memory of the previous dive and not calculate repetitive dives correctly
When I look at things underwater they often seem _________ than they look on the surface.
larger and or nearer
fist to chest?
low on air
Choose the best answer for the signal shown from the choices provided. (guy saying f in sign language but its not sign language)
okay? okay
Choose the best answer for the signal shown from the choices provided. (O with arms above water)
okay? okay (on surface from distance)
bent arm going side to side under water
out of air
breathe 100 percent oxygen and contact emergency medical care.
reading the manufacturers instructions
I should have cylinders filled at a dive center I trust, not use air that tastes or smells bad, nor use air from a compressor designed to fill car tires. This is important to
reduce the risk of breathing contaminated air.
If I were separated from my buddy, the general procedure is to
search for a minute and then go up to reunite with my buddy at the surface
hand to mouth thing
share air
A diver at the surface is moving quickly and jerkily, has the mask off the face, the regulator/snorkel is out of the mouth, and the diver does not respond to directions. The diver is
showing signs of distress (trouble)
Choose the best answer for the signal shown from the choices provided. (guy holding a flat hand and move it side to side)
something is wrong
____________ travels faster in water than it does in air. This is why you cannot easily tell where it comes from.
sound
If I work too hard and find it difficult to breathe underwater, I should
stop all activity and rest, holding onto something for support if possible.
I am close to my buddy and realize I am out of air. The best response is to
switch to my buddy's alternate air source.
When planning a dive with a computer, I use the "plan" or "no stop scroll" mode to determine
the maximum allowable time limits for depths (typically in 3-metre/10-foot increments).
There is an injured diver who is out of the water and is not responding to touch or my voice. The first thing to do would be
to check if the diver is breathing.
Most injuries caused by aquatic animals happen because the animals are
trying to defend myself
What the bottom is made of can cause big changes in
visibility (how far you can see underwater)
