MARS 4740 UGA Scuba Diving Test Spring The first symptom of a sinus squeeze is usually: - ANS - A sharp pain of wedging above the eyes The absolute pressure expressed in terms of atmospheres absolute at 99 feet in salt water is - ANS - 4ATA One atmospheric pressure is defined as: - ANS - All Answers are Correct (1 ata, 34 feet, 33 feet below see level, etc.) Earplugs should: - ANS - Never be worn while diving Body heat is lost_____________ Than in air. - ANS - 25 to 30 times faster The condition in which certain colors are diminished as depth increases is called: - ANS - Absoprtion Absolute pressure is defined as: - ANS - The total pressure exerted on an object The purpose of equalization is to: - ANS - Introduce additional air into body air spaces in response to increasing external pressure Gauge Pressure is defined as: - ANS - absolute pressure minus 1 ata A scuba cylinder must be hydrostatically tested: - ANS - within fixed intervals set by local law The major, and most common, symptom of decompression sickness is: - ANS - Joint Pain The Delivery System components are: - ANS - A regulator, alternate air source, and a high pressure scuba cylinder A high pressure scuba cylinder should be stored: - ANS - lying flat with a minimum of 500 to 750 psi The most efficient breathing pattern for scuba diving is: - ANS - a deep balance exhalation followed by a balanced inhalation without stopping between breaths The three primary features to look for in a quality Exposure System are: - ANS - Thickness, Fit, and Seam Integrity An object immersed in water will be buoyed upward by a force ______ the weight of the water it displaces. - ANS - equal to Which of the following would be inappropriate treatment for a diver exhibiting symptoms of Decompression Sickness? - ANS - Taking the victim back underwater The rate at which the body becomes saturated with nitrogen: - ANS - Will varied based upon depth and blood supply in an area of the body flexible air filled container at 100 feet of sea water has a volume of 10 cu ft would be the volume if it were transported to the surface - ANS - 40 cu ft Overexpansion injuries can be prevented by: - ANS - All answers are correct...Proper system, correct breathing, never hold your breath The only accepted treatment for Arterial Gas Embolism is: - ANS - Stabilize the victim in a medical facility and transport to a decompression chamber for recompression Gas can enter the bloodstream and cause serious damage to the lungs or even death by: - ANS - Holding your breath, ascending too fast, diving with respiratory congestion Decompression sickness occurs when: - ANS - Excess Nitrogen bubbles out of solution into the blood and tissues, a diver stays at a depth too long and surfaces too quickly, the nitrogen tissue tolerance gradient is exceeded The recommended max ascent rate is: - ANS - 30 feet per minute The reciprocal azimuth for an initial azimuth of 60º is: - ANS - 240 degrees A good diving buddy: - ANS - Is familiar with their buddies equipment, makes diving more fun, is able to help in all phases of diving and dive planning Dive computers are essential for planning and executing dives because: - ANS - Monitor ascents and descents, help divers stay within the no-decompression limits, record all pertinent information You should perform a safety stop at 15 feet for 3-5 minutes on every dive - ANS - True Use of the SSI Total DiveLog is important because: - ANS - It keeps an accurate record of your personal information and dives; it contains your medical history and provides important emergency information; it is an important information resource for future dives The most important reason for planning your dives and executing the dive per your plan is to: - ANS - Prevent accidents When entering the water through the surf, dive buddy teams should: - ANS - Maintain physical contact and time entry to coincide with the lull between wave sets Divers should avoid contact with corals because: - ANS - Harmful to diver, damage to coral, damage to equipment When diving in Marine Protected Areas like Marine Parks, divers should: - ANS - Respect and follow the local marine park regulations Coral reefs are formed by: - ANS - Coral animals called polyps, that form skeletal structures If a diver is injured by harmful sea life, it is usually because of: - ANS - Ignorance, negligence &/ aggressive behavior from the diver. (All answers are correct) Divers can help protect the marine environment by: - ANS
