Free PADI Dive Skills Questions and Answers

Question 1

With the exception of: A diver hurt by underwater life may exhibit the following symptoms and indicators:

Accepted Answer

Nail beds and cherry red lips

Answer

Symptoms like localized pain, swelling, or even severe systemic reactions are common when a diver is injured by marine life. However, 'nail beds and cherry red lips' are not typical indicators of such injuries. Cherry red lips are more commonly associated with carbon monoxide poisoning, which is unrelated to marine life encounters, making it the exception.

Question 2

If you see a diver acting foolishly while on a deep dive, the best course of action to help them is to:

Accepted Answer

Bring him up to a lower level.

Answer

A diver acting foolishly on a deep dive is likely experiencing nitrogen narcosis, often called 'rapture of the deep,' caused by the increased partial pressure of nitrogen at depth. The most effective and immediate treatment is to ascend to a shallower depth. This reduces the nitrogen partial pressure, alleviating the narcotic effects and allowing the diver to regain clear thinking.

Question 3

The main ocean currents move clockwise in the ______________ hemisphere and counterclockwise in the _____________ hemisphere.

Accepted Answer

Northern and Southern

Answer

The Coriolis effect, caused by the Earth's rotation, deflects moving objects like ocean currents. In the Northern Hemisphere, this deflection is to the right, causing major ocean currents to circulate in a clockwise direction. Conversely, in the Southern Hemisphere, the deflection is to the left, leading to a counterclockwise circulation pattern.

Question 4

Ocean currents are mostly caused by two key environmental factors:

Accepted Answer

The wind and rotation of Earth

Answer

The primary forces driving major ocean currents are wind and the Earth's rotation. Wind transfers energy to the ocean surface, initiating current movement, while the Coriolis effect (due to Earth's rotation) deflects these currents, creating large-scale circulation patterns known as gyres. Other factors like temperature and salinity also play roles, but wind and rotation are the dominant drivers.

Question 5

In an area with a flat, sandy bottom and often poor visibility, you misplaced a dive knife. What is the best search pattern to use in order to locate this object?

Accepted Answer

use a line to expand a circle

Answer

For searching a small, lost object in poor visibility on a flat, sandy bottom, an expanding circular search pattern is highly effective. The diver secures a line to a central point and then swims in progressively wider circles. This systematic method ensures thorough coverage of the area, minimizing the chance of missing the object in challenging conditions.
