Beginners Scuba Diving Final Exam

Refer to the regulator picture on the right. Each regulator part has a number next to it. Choose one correct answer in each corresponding numbered drop-down list

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)
