PADI OPEN WATER DRIVER FINAL EXAM 2024 NEWEST 2 VERSIONS (VERSION A AND B) COMPLETE 250 QUESTIONS WITH DETAILED VERIFIED ANSWERS/ALREAD Y GRADED A+ VERSION A 1) The best place for me to position an alternate air source is A loose by my side so I can find it fast. B in the triangle area formed by my chin and the lower corners of my rib cage. C to the base of my cylinder. D to the back of my BCD between my sho ulder blades and waist. - ....ANSWER...B In the triangle area formed by my chin and the lower corners of my rib cage. RATIONALE: Your alternate air source attaches with a quick release in the triangle area formed by your chin and the lower corners of your rib cage. Avoid letting your alternate air source dangle unsecured from your kit. See Equipment I - Regulators. 2) Lung overexpansion injuries can be caused by A scuba diving without a buddy. B continuing a dive when not properly weighted. C not drin king enough water before scuba diving. D holding my breath while scuba diving . - ....ANSWER...D Holding my breath while scuba diving. RATIONALE: 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. 3) If my cyli nder 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 - ....ANSWER...B 20 minutes 60/3=20 RATI ONALE: 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. 4) How often should I take m y 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. - ....ANSWER...A Once a year. RATIONALE: Have your cylinder visually inspected annually for internal corrosion or other contamination/damage. See Equipment I - Cylinders. 5) 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. - ....ANSWER...D float. RATIONALE: 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 up ward force. See Being a Diver I - Buoyancy and Controlling Buoyancy.
