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. - A 4) 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. - C 5) If my ears or sinuses hurt while I am descending (going down), it usually means A my air spaces are equalized. B my mask strap is too tight. C I am feeling a squeeze and need to equalize. D my mask is too small. - C 6) The best place for me to position an alternate air source is A loose by my side so I can find it fast.

See Your Skills as a Diver I - Hand Signals. - 26) Choose the best answer for the signal shown from the choices provided. A Turn the dive. B Share air. C I am thirsty. D I have lost my mouthpiece. B Search for a minute and then go up to reunite with my buddy at the surface. The general procedure for buddy separation is to search for no more than one minute, then surface to reunite. See Being a Diver II - The Buddy System. - 27) If I were separated from my buddy, the general procedure is to A go up immediately, wait a minute and then go back down. B search for a minute and then go up to reunite with my buddy at the surface. C go to the surface immediately and get out of the water. D look for my buddy's bubbles and follow the bubbles to find my buddy. D In midwater 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. - 28) I am most likely to become confused about which way is up or down _____________. A at the surface B near the surface C on the bottom D in midwater 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. - 29) 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. 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. - 30) 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). 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. - 31) Most injuries caused by aquatic animals happen because the animals are A hungry. B curious. C injured. D trying to defend themselves. 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. happened. D to provide oxygen. 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. - 37) 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. 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. - 38) 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. B Dive while tired, cold, sick, thirsty or injured. Secondary factors that can contribute to developing decompression sickness include fatigue, dehydration, cold, poor fitness, high body fat, illness, injuries, age, alcohol consumption before or after a dive, and vigorous exercise before, during or immediately after a dive. See Being a Diver IV - Decompression Sickness. - 39) 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. C do not look after my equipment. D am using a dive computer. C Breathe 100 percent oxygen and contact emergency medical care. For a suspected case of decompression illness, contact emergency medical care, lie down and breathe emergency oxygen. Almost all cases of decompression illness require treatment in a recompression chamber. Don't delay first aid and getting to treatment. See Using Dive Computers and Tables II - First Aid Treatment for Decompression Illness. - 40) If I think I have decompression sickness I should A stop diving until I feel better. B go back in the water. C breathe 100 percent oxygen and contact emergency medical care. D see a doctor when I can. B Reading the manufacturer's instructions. 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. - 41) The first step in using my dive computer is A setting the time and date. B reading the manufacturer's instructions. C calibrating it for enriched air nitrox. D setting it for fresh or salt water. 42) When planning a dive with a computer, I use the "plan" or "no stop scroll" mode to determin e 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. - B 43) 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. - A 44) 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. - B 45) 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. - B 46) If I'm diving in cold water or under strenuous conditions A I should add an extra safety margin and stay well within my computer's limits. B nitrogen absorption will be slower so I can stay longer. C my dive computer will probably not work at all. D I do not need to do anything special. - A 47) 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 A ascend (go up), make a safety stop and end the dive.
