PADI OPEN WATER BEING A DIVER 1
CERTIFICATION ASSESSMENT 2026 VERIFIED
ANSWERS GRADED A+
◉ Why does a congestion from a cold or allergy temporarily keep me
from diving?
Answer: Congestion might block normal air flow, making
equalization difficult or impossible
◉ Why should I never dive with earplugs?
Answer: They create air spaces that you can't equalize
◉ What other body air spaces are affected by increasing pressure?
How do I equalize them?
Answer: In filled teeth - go to a dentist
In a dry suit - learn from an instructor
Lungs - breathe normally and continuously
◉ What is the most important rule in scuba diving?
Answer: Breathe continuously and never hold your breath
,◉ What can happen if I don't follow the most important rule in
scuba diving?
Answer: Your lungs will over expand and rupture
◉ What is a "reverse block"?
Answer: When expanding air becomes trapped in your body air
spaces as you ascend
◉ What should I do if I feel discomfort in my ears, sinuses, stomach,
intestines, or teeth while ascending?
Answer: Stop your ascent and descend a meter/few feet to reduce
discomfort and give trapped air time to work its way out
◉ How does depth affect how long my air supply lasts?
Answer: The deeper you are, the more dense air you breathe, and
the faster you use the air in your cylinder. Compared to the surface,
air supply lasts 1/#ata as long along with other factors
◉ What's the most efficient way to breathe dense air underwater?
Answer: Take slow, deep breaths
◉ How do I breathe to reduce anxiety when under stress?
Answer: Do NOT breathe faster - keep breathing slowly
, ◉ What are my 4 breathing rules as a scuba diver?
Answer: 1. Breathe continuously and never hold your breath
2. Breathe slowly and deeply
3. Don't allow yourself to get winded or out of breath
4. If faced with a problem, stop, and reduce anxiety by breathing
slowly and deeply
◉ What is buoyancy?
Answer: An upward force acting on an object in the water, canceling
the pull of gravity
◉ What causes buoyancy?
Answer: The upwards force is caused by the water displaced by the
object, and is equal to the weight of displaced water
◉ positive buoyancy
Answer: The object weighs less than the water it displaces, so it
floats
◉ neutral buoyancy
Answer: The object weighs the same as the water it displaces,
neither sinking nor floating
