Free PADI Open Water Diver Questions and Answers

Question 1

I can utilize my backup computer to finish the dive if my primary computer malfunctions. If I don't have a backup on, I ought to:

Accepted Answer

Ascend (go upward), halt for safety, and stop the dive.

Answer

If a primary dive computer malfunctions and no backup is available, the safest and most responsible action is to immediately end the dive. This involves making a controlled ascent, including a safety stop, to minimize the risk of decompression sickness. Continuing the dive without essential depth and time information is extremely dangerous, and relying on another diver's computer is not a safe personal solution.

Question 2

Unless specifically stated otherwise by law, I should remain within ___________ of my dive flag.

Accepted Answer

fifteen meters

Answer

Dive flags are vital safety markers that alert surface vessels to the presence of divers underwater. Staying within fifteen meters (50 feet) of the dive flag ensures divers remain within the protected zone it designates. This regulation is crucial for preventing collisions and enhancing diver safety by clearly indicating their location to boats.

Question 3

Decompression sickness (DCS) is more likely to strike me if I:

Accepted Answer

dive when you're dehydrated, sick, cold, or hurt.

Answer

Certain physiological conditions significantly increase a diver's susceptibility to decompression sickness (DCS). Diving while dehydrated, sick, cold, or injured can impair the body's ability to efficiently off-gas nitrogen, making DCS more likely. Maintaining good health and hydration is crucial for minimizing dive risks.

Question 4

Two dives are planned by a group of advanced open water divers. The first dive lasts 20 minutes on a reef in a depth of 22 meters. After that, the group spends an hour on the surface. The second dive is scheduled to take place on a wreck in 18 meters of water, with a 30-minute bottom duration. After the second dive, what pressure group will finish first?

Accepted Answer

R

Answer

To determine the final pressure group, one must apply the PADI Recreational Dive Planner (RDP) or equivalent dive computer logic. After the first dive (22m for 20min) and a 60-minute surface interval, residual nitrogen is calculated. For the second dive (18m for 30min), this residual nitrogen is added to the actual bottom time. Following these calculations according to dive planning rules results in Pressure Group R.

Question 5

I begin my dive feeling a slight stream. How should this dive start for me?

Accepted Answer

Jump into or against the current.

Answer

When entering the water with a slight current, it is generally recommended to jump into or against the current. This allows divers to descend quickly and get below the main force of the current, where it is often weaker and easier to manage. Entering with the current could cause divers to be swept away from their intended descent point or boat.
