1. AGE.
- Type I DCS.
- Type II DCS.
- subcutaneous emphysema. - ✔ ✔ 2. Type I DCS.

- entering the arterial bloodstream.
- collapsing a lung.
- accumulating in the center of the chest.
- accumulating under the skin at the base of the neck. - ✔ ✔ 1.

As a divemaster, your role is generally to provide __________ planning that other divers use to plan their individual buddy team dives within.
- complete
- broad
- detailed - ✔ ✔ 2. broad
You provide broad planning for the group because you know the dive site and local environment. By supplying guidelines, you allow divers to plan their individual dives.

At the surface at sea level, the absolute pressure is
- 0 bar/ata
- 1 bar/ata
- 2 bar/ata - ✔ ✔ 2. 1 bar/ata

Ambient pressure means "surrounding pressure" and at sea level you are at 1 bar/ata.
Before a dive along a wall that drops into extremely deep water, you notice a diver seems preoccupied and withdrawn. You talk to the diver and learn the person doesn't feel adequately skilled with buoyancy control and fears descending out of control. What could you do to help the diver with this predive stress?
- Review buoyancy control and guide the diver to a part of the site that is away from deep water.
- Have the diver reduce the amount of weight worn for this dive.
- Advise the diver not to make the dive. - ✔ ✔ Stress is relieved by either removing the stressor or changing the diver's perception of the stressor so it's no longer threatening.
Being knowledgeable about the biological and physical properties of the underwater world is important because it helps you with dive planning.

Currents that affect divers are commonly caused by (choose all that apply)
- the Earth's rotation.
- waves.
- wind.

Divemaster Dawn is escorting several PADI Advanced Open Water Diver course students on the Fish Identification Adventure Dive. PADI Standards allow adult students to dive as deep as 30 metres/100 feet on this dive, but there is a thermocline and reduced visibility at 12 metres/40 feet. Of the following choices, which is likely Dawn's best decision under these circumstances?
- Allow the divers to go as deep as standards allow.
- Cancel the dive entirely.
- Limit the dive to 12 metres/40 feet and shallower. - ✔ ✔ 3. Limit the dive to 12 metres/40 feet and shallower.
Your judgment is required to determine how to apply PADI Standards to each situation. Environmental conditions may lead you to decide to lower ratios, use a shallower depth, cancel or abort the dive, or tighten control in order to reduce risk.
Diving in an environmentally responsible manner is important so you role-model this behavior. It's also important because
