1. During a static apnea attempt, the primary objective is to:
A. Swim the greatest possible distance underwater
B. Descend to the deepest possible depth
C. Remain motionless while holding the breath for the longest possible
time
D. Perform dynamic finning techniques underwater
Answer: C
Rationale: Static apnea is a breath-hold discipline in which the diver remains
stationary, usually floating face-down in water, while attempting to
maximize breath-hold duration through relaxation and efficient oxygen
conservation.
2. Which gas primarily triggers the urge to breathe during a breath-hold?
A. Oxygen
B. Carbon dioxide
C. Nitrogen
D. Helium
Rationale: Rising carbon dioxide (CO₂) levels stimulate chemoreceptors that
create the urge to breathe. Oxygen levels can become critically low before
the urge becomes overwhelming, making hypoxia particularly dangerous.
, 3. Before beginning a static apnea session, the buddy's primary
responsibility is to:
A. Dive simultaneously with the participant
B. Stay several meters away
C. Continuously monitor the diver throughout the attempt
D. Leave the diver undisturbed until the planned breath-hold ends
Rationale: A trained buddy must maintain uninterrupted observation to
recognize signs of distress, intervene immediately if necessary, and ensure
diver safety throughout the entire breath-hold.
4. Hyperventilation before static apnea is dangerous because it:
A. Increases oxygen storage dramatically
B. Reduces carbon dioxide, delaying the urge to breathe while not
significantly increasing oxygen
C. Increases nitrogen absorption
D. Prevents lung squeeze
Rationale: Hyperventilation lowers CO₂ without substantially increasing
oxygen content, allowing oxygen levels to fall dangerously low before
normal warning signals appear.
5. Which breathing technique is generally recommended immediately
before a static apnea attempt?
A. Rapid deep breathing for one minute
B. Continuous forceful exhalations
C. Calm, controlled diaphragmatic breathing followed by a relaxed
final breath
D. Panting rapidly until lightheaded
Rationale: Controlled relaxation breathing optimizes comfort and reduces
anxiety while avoiding excessive reduction of CO₂ that can increase blackout
risk.
6. During static apnea, the diaphragm contractions experienced later in
the breath-hold are primarily caused by:
, A. Excess oxygen
B. High nitrogen pressure
C. Rising carbon dioxide levels
D. Ear equalization failure
Rationale: Diaphragm contractions are involuntary muscular responses to
increasing CO₂ and indicate progressing respiratory drive rather than
immediate oxygen depletion.
7. A loss of motor control (LMC) during static apnea is characterized by:
A. Complete unconsciousness
B. Ear pain and dizziness
C. Involuntary muscle movements with impaired coordination while
still conscious
D. Chest pain only
Rationale: LMC results from cerebral hypoxia and often presents as shaking,
facial twitching, or inability to perform simple tasks despite maintained
consciousness.
8. If a diver experiences a blackout during static apnea, the buddy should
first:
A. Leave the diver floating until spontaneous recovery
B. Immediately support the airway above water and initiate rescue
procedures
C. Shake the diver violently underwater
D. Continue timing the attempt
Rationale: Immediate airway support, mask removal if applicable,
stimulation, and rescue breathing if required are essential priorities during
blackout management.
9. The recovery breathing protocol after surfacing typically consists of:
A. Rapid hyperventilation
B. Short active inhalations followed by controlled passive exhalations
