1) If an object is neutrally buoyant (does not sink or float) in fresh water, the

same object placed into salt water would

A sink.

B either sink or float.

C do nothing.

D float. ------CORRECT ANSWER---------------D float.

Salt water is heavier than fresh water because it has dissolved

minerals in it. This means it causes more upward force (buoyancy) on

an object. An object that is neutrally buoyant in fresh water would

float in salt water because there is greater upward force.

See Being a Diver I - Buoyancy and Controlling Buoyancy.

2) 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?

A The balloon will get bigger and the air inside the balloon will be less

dense (molecules move further apart).

B The balloon will get smaller and the air inside the balloon will be more

dense (molecules move closer together).

C The balloon will get bigger and the air inside the balloon will be more

dense.

D The balloon will get smaller and the air inside the balloon will be less

dense. ------CORRECT ANSWER---------------B The balloon will get smaller

If an object is neutrally buoyant (does not sink or float) in fresh water, the same object placed into salt water would A sink. B either sink or float. C do nothing. D float. ------CORRECT ANSWER---------------D float. Salt water is heavier than fresh water because it has dissolved minerals in it. This means it causes more upward force (buoyancy) on an object. An object that is neutrally buoyant in fresh water would float in salt water because there is greater upward force. See Being a Diver I - Buoyancy and Controlling Buoyancy.
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? A The balloon will get bigger and the air inside the balloon will be less dense (molecules move further apart). B The balloon will get smaller and the air inside the balloon will be more dense (molecules move closer together). C The balloon will get bigger and the air inside the balloon will be more dense. D The balloon will get smaller and the air inside the balloon will be less dense. ------CORRECT ANSWER---------------B The balloon will get smaller

and the air inside the balloon will be more dense (molecules move closer together). As water pressure increases, the volume of an air space will decrease. This causes the density of the air inside to increase and air molecules are pushed closer together. The balloon would get smaller and the air density inside would be greater. See Being a Diver I - Water Pressure and Air Volume Effects.

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 meters. The air space would A become half the size it was at the surface. B not change in size. C become 1/3 the size it was at the surface. D become 2/3 the size it was at the surface. ------CORRECT ANSWER------ ---------A become half the size it was at the surface. At 10 meters, the pressure is 2 bar. An air volume taken to this depth from the surface would decrease and become half the size. See Being a Diver I - Water Pressure and Air Volume Effects.
If I am not able to equalize (clear) my body air spaces, it may be because I have A seasickness. B heart disease and high blood pressure. C a cold, allergy or another medical problem. D anxiety. ------CORRECT ANSWER---------------C A cold, allergy or another medical problem. A cold, or any congestion, can block air passages in your ears and sinuses, making equalization difficult or impossible.

Lung overexpansion injuries can be caused by A scuba diving without a buddy. B continuing a dive when not properly weighted. C not drinking enough water before scuba diving. D holding my breath while scuba diving. ------CORRECT ANSWER----------- ----D Holding my breath while scuba diving. Blocking off your lungs by holding your breath and ascending could cause them to overexpand and rupture, which is a serious injury that could result in paralysis and death. Breathing continuously while scuba diving keeps air passages open allowing expanding air to escape. See Being a Diver I - The Effects of Decreasing Pressure on Body Air Spaces.
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 meters breathing normally? A 60 minutes B 20 minutes C 15 minutes D 12 minutes ------CORRECT ANSWER---------------B 20 minutes 60/3= For each 10 meters we go down, we have one more atmosphere of pressure. Also, remember to add in the 1 atmosphere of pressure at the surface. So, going down to 20 meters, we will have 2 atm + 1 atm = 3 atm of pressure.

How often should I take my scuba cylinder to be visually inspected by my dive center? A Once a year. B Once every two years. C Every six months. D Every five years. ------CORRECT ANSWER---------------A Once a year. Have your cylinder visually inspected annually for internal corrosion or other contamination/damage. See Equipment I - Cylinders.
The difference between DIN valves and yoke valves is that DIN valves A are made from durable plastic. B contain a spring-operated shutoff valve that is held open by cylinder pressure. C have an o-ring in them. D have threaded openings to screw the regulator into. ------CORRECT ANSWER---------------D Have threaded openings to screw the regulator into. With the DIN system, the regulator screws into the valve. The yoke system holds the regulator first stage to the cylinder with a clamp system. See Equipment I - Cylinders.
Which of the following is part of proper care for my scuba cylinder? A Sand and repaint it every year. B Dry it in the sun. C Keep some air in it. D Have it pressure tested every month. ------CORRECT ANSWER------------ ---C Keep some air in it.

As light travels through water and into your mask, it bends, or refracts. This makes objects appear larger and closer than they really are. See Being a Diver II - Seeing and Hearing as a Diver.

___________ travels faster in water than it does in air. This is why you cannot easily tell where it comes from. A Light B Current C Aquatic life D Sound ------CORRECT ANSWER---------------D Sound Sound travels about four times faster in water than in air. This makes it difficult to determine where the sound is coming from because it seems to come from all around or directly overhead. See Being a Diver II - Hearing Underwater.
Unless there are laws that say differently, I should stay within ___________ of my dive flag. A 60 meters B 30 meters C 15 meters D 5 meters ------CORRECT ANSWER---------------C 15 meters If there are no specific local laws regarding dive flags, stay within 15 meters of the flag. Boats should stay 30 to 60 meters away. See Equipment III - Dive Flags.

If I work too hard and find it difficult to breathe underwater, I should A inflate my BCD. B stop all activity and rest, holding onto something for support if possible. C swim immediately to my buddy and signal for help. D do a controlled emergency swimming ascent (CESA - swimming up to the surface saying the ah-h-h-h sound). ------CORRECT ANSWER------------ ---B Stop all activity and rest, holding onto something for support if possible. If you find it difficult to breathe you're overexerted. Immediately stop and rest while holding onto something for support to restore normal breathing. Continue only after you've regained a normal, slow breathing rate. See Being a Diver II - Overexertion.
As I descend (go down), my wet suit will A compress (feel thinner) from water pressure, and I will lose buoyancy and warmth. B expand (feel thicker) from water pressure, and I will gain buoyancy and warmth. C remain the same thickness from the water pressure, and there will be no change in warmth. D expand (feel thicker) from water pressure, and I will lose buoyancy and warmth. ------CORRECT ANSWER---------------A Compress (feel thinner) from water pressure, and I will lose buoyancy and warmth. The small bubbles in your wet suit compress as you get deeper. This causes your buoyancy to decrease and makes the wet suit thinner, which affects warmth. To control your buoyancy, add small amounts of air to your BCD frequently during descent. See Being a Diver II - Descents in Open Water.
I know I am properly weighted for diving if I

This is the hand signal for something is wrong. See Your Skills as a Diver I - Hand Signals.

Choose the best answer for the signal shown from the choices provided. A My finger is cold. B Go around the rock. C Okay? Okay. D Stay together. ------CORRECT ANSWER---------------C Okay? Okay. This is the hand signal for Okay. See Your Skills as a Diver I - Hand Signals.
Choose the best answer for the signal shown from the choices provided. A Wave to friends on the beach. B I need more weight. C Distress, help. D I need the boat to pick me up. ------CORRECT ANSWER---------------C Distress, help. This is the hand signal for distress or I need help on the surface. See Your Skills as a Diver I - Hand Signals.
Choose the best answer for the signal shown from the choices provided. A Okay? Okay. (on the surface at a distance)

B I have cramps in my legs. C I would like to snorkel in. D Boat pick up, I have air. ------CORRECT ANSWER---------------A Okay? Okay. (on the surface at a distance) This is the hand signal for Okay on the surface. See Your Skills as a Diver I - Hand Signals.

Choose the best answer for the signal shown from the choices provided. A Which way to the boat? B Stay at this depth. C Go this way. D Out of air. ------CORRECT ANSWER---------------D Out of air. This is the hand signal for out of air. See Your Skills as a Diver I - Hand Signals.
Choose the best answer for the signal shown from the choices provided. A Look at me. B Low on air. C Share air. D Go up. ------CORRECT ANSWER---------------B Low on air. This is the hand signal for low on air. See Your Skills as a Diver I - Hand Signals.

When descending and ascending in reduced visibility, you can feel disoriented, especially in mid-water when you can't see either the bottom or the surface. See Being a Diver III - Visibility.

I feel a mild current at the start of my dive. How should I begin this dive? A Dive with the current. B Dive across the current. C Dive against or into the current. D Dive at an angle to the current. ------CORRECT ANSWER---------------C Dive against or into the current. By swimming into a current for the first part of a dive, you can let it carry you back to where you started during the second part. See Being a Diver III - Water Movement.
What the bottom is made of can cause big changes in A visibility (how far you can see underwater). B temperature (how warm the water is). C current (the movement of water). D buoyancy (whether you sink or float). ------CORRECT ANSWER------------ ---A Visibility (how far you can see underwater). The nature and composition of particles in the water affects visibility. Large, heavy material - like from gravel and rock bottoms - settles out of the water quickly, restoring visibility quickly. Small, light particles - like from mud and clay bottoms - can remain suspended for very long periods. See Being a Diver III - Visibility.

Most injuries caused by aquatic animals happen because the animals are A hungry. B curious. C injured. D trying to defend themselves. ------CORRECT ANSWER---------------D Trying to defend themselves. Nearly all aquatic life injuries result from defensive actions by the animals. You can generally avoid injuries by being aware and respectful of aquatic organisms. See Being a Diver III - Aquatic Life.
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 A giving the okay signal. B performing a predive safety check. C excited about the dive. D showing signs of distress (trouble). ------CORRECT ANSWER--------------- D Divers who are distressed or panicked often have their masks on their foreheads and don't use their breathing equipment. They usually have wide, unseeing eyes, quick and jerky movements, and do not follow instructions. They need immediate help because they may continue to struggle until exhausted. See Being a Diver III - Surface Problem Management - Responsive Diver.
I am close to my buddy and realize I am out of air. The best response is to

A ascend using my buddy's alternate air source / make a controlled emergency swimming ascent B ascend using my buddy's alternate air source / make an buoyant emergency ascent C make a normal ascent / ascend using my buddy's alternate air source D make a controlled emergency swimming ascent / make a normal ascent - -----CORRECT ANSWER---------------A Ascend using my buddy's alternate air source / make a controlled emergency swimming ascent You can make a normal ascent when very low on air, but your cylinder isn't completely empty. When out of air, your best option is usually to make an alternate air source ascent using your buddy's alternate air source. Make a controlled emergency swimming ascent when fairly shallow and the surface is closer than a buddy with an alternate air source. Make a buoyant emergency ascent when your buddy is not near and you're deep enough that you don't think you can make it to the surface by just swimming. See Being a Diver III - Underwater Problem Management.

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 A to check if the diver is breathing. B to keep the diver warm. C to decide what happened. D to provide oxygen. ------CORRECT ANSWER---------------A To check if the diver is breathing. Your priority when assisting someone who is unresponsive is to make sure the diver is breathing. Provide rescue breaths as necessary. Contact emergency medical care. See Being a Diver III - First Responder Care for Diving-Related Emergencies.

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 A decrease the likelihood of gas narcosis. B increase the enjoyment of my dive. C reduce the risk of lung overexpansion injuries. D reduce the risk of breathing contaminated air. ------CORRECT ANSWER- --------------D Reduce the risk of breathing contaminated air. Contaminated air is rare because it's easy to avoid by getting your cylinders filled at reputable scuba air sources - namely, professional dive operations. Dive centers and resorts take care of their fill systems and know the value of regular air testing. See Being a Diver IV - Contaminated Air.
Divers who act foolishly at depth due to gas narcosis may start acting normally again if they A ascend (go up) to a shallower depth. B breathe slowly and deeply. C signal their buddy for help. D dive within no stop limits. ------CORRECT ANSWER---------------A Ascend (go up) to a shallower depth. If you or a buddy experience narcosis, immediately ascend to a shallower depth. Narcosis generally fades quickly when you return to a shallower depth. See Being a Diver V - Gas Narcosis.
I am likely to increase the risk of decompression sickness (DCS) if I A dive in poor visibility, strong moving water, and rough seas. B dive while tired, cold, sick, thirsty or injured.

Before you dive with a computer, you need to read the manufacturer's dive computer manual. It's your responsibility to read and understand the manufacturer's instructions. See Using Dive Computers and Tables I - Planning Dives with Your Computer.

When planning a dive with a computer, I use the "plan" or "no stop scroll" mode to determine A the maximum depth of the previous dive. B the maximum allowable time limits for depths (typically in 3-meter). C whether my computer is compatible with my buddy's computer. D the best settings for my backup computer. ------CORRECT ANSWER----- ----------B The maximum allowable time limits for depths (typically in 3- meter). You plan dives with your dive computer by activating it and scrolling the no stop limits. With most computers, you scroll depths in 3 meter increments, displaying the maximum time allowed at each depth. Agree with your buddy on a maximum depth based on the no stop times displayed. See Using Dive Computers and Tables I - Planning Dives with Your Computer.
When making computer assisted dives A each diver needs a personal computer. B each buddy team needs a computer C up to four divers may share a computer. D all divers may follow the dive guide's computer. ------CORRECT ANSWER---------------A Each diver needs a personal computer. Divers can't share a dive computer. Each diver needs a computer and the buddy team should follow the most conservative computer to turn or end a dive.

See Using Dive Computers and Tables I - Diving with Your Computer.

It's important that I do not turn off a dive computer between dives because A the divemaster may object because I can't recall the dive information for logging. B it would lose memory of the previous dive and not calculate repetitive dives correctly. C it won't come back on, or it may take a long time to power up. D doing so is hard on the batteries and may cause the computer to fail. -----

CORRECT ANSWER---------------B It would lose memory of the previous dive and not calculate repetitive dives correctly. Your dive computer tracks your personal theoretical nitrogen levels continuously during all your dives and surface intervals. For your safety, to keep an accurate account, you must not turn off your computer and need to use the same computer the entire diving day, on all dives. See Using Dive Computers and Tables I - Repetitive Diving.

If I accidentally exceed my computer's no stop limits, I should A make a safety stop for three minutes at 5 meters. B follow the computer's instructions for decompression. C surface immediately, breathe oxygen and report my condition to the divemaster. D make a controlled ascent and refer to the manufacturer's literature for decompression procedures. ------CORRECT ANSWER---------------B Follow the computer's instructions for decompression. If you exceed a no stop limit, you will have to make an emergency decompression stop. You computer will go into decompression mode and guide you by providing the depth of your emergency decompression stop and how long you have to stay there before you can ascend to the surface.
