Swallow and wiggle the jaw from side to side c. Block my nose and blow forcefully for an extended period - Block my nose and attempt to blow gently through it During a descent, I try to equalize but discover I'm having trouble doing so. Which of the following is correct - Stop my descent, signal my buddy, ascend slightly, and try again. I should equalize ______ and _____. - Early and often I should not dive with a cold, nor use medications to dive with a cold a. True b. False - True The most important rule in scuba diving is - a. Breathe continuously and never hold my breath Failure to follow the MOST important rule in scuba diving can cause serious lung over expansion injuries, which in turn can cause paralysis and death True or false? - True If I feel discomfort in a body air space while ascending, the correct action is to: a. Continue my ascent while blowing against blocked nostrils b. Stop, descend slightly and give trapped air time to work its way out. c. Descend at least 10metres/33feet, then resume my ascent - B My buddy and I are planning a dive to 18 meters/ 60 feet. We would expect our air supply to last A- longer than B- shorter than C- the same as - B During a dive, I swim hard to keep up with the fish that interests me, but shortly I begin to feel like I can't get enough air. The correct action would be to: a. Signal my buddy and head up to the surface b. Use the regulator purge button to boost air flow c. Stop all activity and rest to restore proper deep, slow breathing - C An object that is neutrally buoyant I'm fresh water will_________in salt water - Float The three overall benefits of the buddy system are practicality, safety, and fun a. True b. False - True (if you said false ur either stupid or anti social) The primary considerations when choosing any piece of scuba gear are - Suitability, fit, and comfort I'm planning to dive the following week and am checking my gear, I put my kit together and notice that my regulator seems to breathe harder than I remember. The appropriate action to take would be to - Have it inspected and serviced as needed by a professional before using it. There is No way to use a DIN regulator on a yoke cylinder valve. True or false? - False It is important to master buoyancy control because it allows me to control whether I descend float or am neutrally buoyant, I adjust my buoyancy frequently while diving True or false? - True I take a colorful fish identification slate with me while diving. Looking at the slate underwater at 12metres/40feet, I would expect the slate to look a. smaller/farther away b. more colorful c. less colorful d. larger/closer - D and c While underwater, I want to more efficiently by a. moving as quickly as possible b. being streamlined c. having just a little more weight than I actually need d. swimming slowly and steadily e. maintaining proper trim - B, D, and E During a dive, I can't stop shivering. The proper response would be to a. exit the water immediately, dry off, and seek warmth b. exit the water as planned, but wear more exposure protection next time c. exit the water when convenient, and swim rapidly to warm up - A During a dive, my buddy and I have to swim hard because of an unexpected current. If I were to begin to feel fatigued, have labored breathing, experience a feeling of suffocation or air starvation, and perhaps feel like I may panic, I should a. signal "up" and head to the surface b. switch to an alternate air source c. stop all activity, signal my buddy and rest - c. stop all activity, signal my buddy and rest When planning our dive, my two buddies and I agreed that the general procedure for buddy separation would be adequate. If during the dive I find I am with one buddy but can't see the other, what do I do? - Stay with the remaining buddy and search for no more than a minute, then reunite on the surface. The buddy system is who's responsibility? - MY responsibility My buddy and I are planning a shore dive, we're descending onto a very gradual slope that begins at 5 meter/15 feet, so our descent and ascent will be gradual part of swimming out and back under water. We have similar cylinders filled to 200 bar/3000 psi, we plan 50 bar/500 psi reserve 20 bar/300 psi reserve To turn the dive when we've used one third of the air available to use on the dive. This means we should head back when either of our SPGs read - 157 bar/2270 psi My fin strap comes loose (later I discover that I didn't buckle it properly) while swimming at the surface in choppy waves. Which of the following habits would help me as I handle this problem? a. Having my mask on and a mouthpiece in my mouth. b. Having enough air in my BCD for adequate buoyancy c. Staying close to and signaling my buddy - a. Having my mask on and a mouthpiece in my mouth. b. Having enough air in my BCD for adequate buoyancy c. Staying close to and signaling my buddy I'm about to begin a descend with my buddy, which of the following steps should I take before actually beginning my descent? - Orient myself to something at the surface, check that my computer is active, and confirm that my buddy is ready My buddies and I are wearing wet suits for exposure protection. As I descend, my buoyancy will __________, so I should ___________ to control my buoyancy. a. remain constant, do nothing b. increase, release air infrequently from my BCD in large amounts c. increase, release air frequently from my BCD in small amounts d. decrease, add air infrequently to my BCD in large amounts e. decrease, add air frequently to my BCD in small amounts - e. decrease, add air frequently to my BCD in small amounts I should never descend or ascend without a reference that I can follow or make contact with. a. True b. False - False As a prudent, conservative diver, the following are normal parts of my ascents: a. ascending at 18 m/60 ft per minute (or slower if specified by my computer) b. inflating my BCD to begin my ascent c. stopping for 3 minutes at approximately 5 m/15 ft d. adjusting my buoyancy in small amounts frequently - a. ascending at 18 m/60 ft per minute (or slower if specified by my computer) c. stopping for 3 minutes at approximately 5 m/15 ft d. adjusting my buoyancy in small amounts frequently While boat diving, my buddy and I finish our safety stop and ascend to the surface. When I reach the surface, I should a. Switch to my snorkel, inflate my BCD and signal "okay" to the dive master b. Signal "okay" to the dive master, switch to my snorkel and inflate my BCD c. Inflate my BCD, switch to my snorkel and signal "okay" to the divemaster - c. Inflate my BCD, switch to my snorkel and signal "okay" to the divemaster Match the letter with the characteristics of the exposure suit type ___wet suit ___dry suit ___skin suit A- insulation provided by a layer of air and undergarment B- proper fit is important to keep water trapped against your body C- little or no insulation - B- wet suit A- dry suit C- skin suit Which of the following can be a problem before the dive when diving on a warm day in a wet suit or dry suit? - Overheating If I have only one cutting tool, the recommendation is that I wear it where ___________ hand can reach it a. my right b. my left c. my dominant d. either - d. either One way to avoid disorientation while descending and ascending is to - Follow a reference My buddy and I are diving from a boat and there's a mild current, in most circumstances, we would__________________for the first part of the dive. - Swim into the current My buddy and I get disoriented while boat diving There is a mild current, and we surface away from the boat. We should ____________. If unable to reach the boat or too tired we should ____________. a. swim into the current to get ahead of the boat, redescend and return to the bottom b. swim across the current to reach the trail line, become buoyant and signal the boat to pick us up c. signal that we are okay, swim for shore d. swim with the current until rested, swim to the bottom and swim into the current - b. swim across the current to reach the trail line, become buoyant and signal the boat to pick us up My buddy and I remain neutrally buoyant and stay above the bottom enough to avoid contact. We do this because bottom contact a. may injure or kill fragile aquatic life b. tends to disturb the bottom and reduce the visibility c. increase the risk of accidental cuts, scrapes, or stings - All of the above When assessing conditions, if there is anything that causes me significant anxiety and concern, if I can't address it, I should not dive. Ultimately, I am responsible for my own safety, so I can make the decision to dive True or false? - True (if you thought false, you probably don't have a soul.) When planning to dive in an environment that is new to me, it is recommended that I get a local orientation from an experienced diver or professional who knows the procedures, hazards, points of interest and other factors unique to the environment. True or false - True
