IDC-Guide Quiz Answers

Answers

Quiz 1:

1. Decompression Sickness: The primary cause is the formation of gas bubbles in the body due to a rapid decrease in pressure, typically caused by ascending too quickly.
2. Rescue Techniques: The first step is to establish buoyancy to prevent both the rescuer and the victim from sinking.
3. Physics of Diving: Increasing depth causes a loss of color, starting with red, then orange, and so on through the spectrum.
4. Dive Planning: They are used to track nitrogen absorption and release in a diver’s body, helping to manage the risk of decompression sickness.
5. Scuba Equipment: Inflation/deflation mechanism for buoyancy control and overpressure relief valves for safety.
6. Environment and Ecosystem: Coral reefs provide habitat for a large variety of marine life and help in protecting coastlines from erosion.
7. Dive Skills: The diver without air signals for help, shares the buddy’s alternate air source, and both divers maintain close contact and ascend slowly while breathing alternately.
8. Teaching Methods: The PADI system includes knowledge development, confined water training, and open water training with a focus on performance-based learning.
9. Dive Safety: Ear barotrauma is the most common injury, preventable by equalizing ear pressure frequently during descent.
10. Navigation Skills: Using a compass for straight-line navigation and natural navigation, which involves using underwater landmarks and topography.
