NAUI Instructional Techniques & Rescue Protocols 2 — Questions and Answers
Question 1: When a panicked diver on the surface refuses to let go of you and pulls you underwater, what is the FIRST action you should take?
- Submerge to escape their grip (Correct answer)
- Signal for help and attempt to calm them verbally
- Inflate your BCD to stay on the surface
- Immediately tow them to shore
Correct answer: Submerge to escape their grip
Submerging removes the panicked diver's ability to use you as a float and breaks their grip, allowing you to surface behind them in control.
Question 2: In NAUI's instructional framework, which learning domain covers the development of physical diving skills like mask clearing?
- Cognitive domain
- Affective domain
- Psychomotor domain (Correct answer)
- Behavioral domain
Correct answer: Psychomotor domain
The psychomotor domain encompasses the development and refinement of physical and motor skills through practice.
Question 3: A student diver is found unresponsive on the bottom at 20 feet. After ascent and removal from the water, there is no pulse. What is the correct sequence?
- Begin rescue breaths, then call EMS
- Call EMS and begin CPR immediately (Correct answer)
- Check for breathing for 2 minutes before acting
- Administer oxygen before calling EMS
Correct answer: Call EMS and begin CPR immediately
For an unresponsive, pulseless victim, calling EMS and starting CPR immediately maximizes the chance of survival.
Question 4: What is the recommended student-to-instructor ratio for open water scuba training dives according to NAUI standards?
- 4:1
- 6:1
- 8:1 (Correct answer)
- 10:1
Correct answer: 8:1
NAUI standards specify a maximum ratio of 8 students per instructor during open water training dives.
Question 5: During a rescue scenario, you notice a diver floating face-down but is still breathing. What is this condition called and what is your priority?
- Secondary drowning; monitor and transport
- Near-drowning; flip face-up and support airway (Correct answer)
- Shallow water blackout; submerge to check responsiveness
- Decompression sickness; keep horizontal
Correct answer: Near-drowning; flip face-up and support airway
A face-down breathing diver is considered near-drowning; immediately turning them face-up and maintaining a clear airway is the priority.
Question 6: Which teaching method involves an instructor demonstrating a skill underwater while students watch before attempting it themselves?
- Guided discovery
- Lecture-demonstration (Correct answer)
- Role-playing
- Simulation
Correct answer: Lecture-demonstration
The lecture-demonstration method pairs verbal instruction with a physical demonstration before student practice.
Question 7: A diver surfaces with a bloody froth at the mouth, confusion, and difficulty breathing after a rapid ascent. Which condition should the rescuer suspect?
- Nitrogen narcosis
- Arterial gas embolism (Correct answer)
- Oxygen toxicity
- Carbon dioxide toxicity
Correct answer: Arterial gas embolism
Bloody froth, neurological symptoms, and respiratory distress following rapid ascent are classic signs of arterial gas embolism (AGE).
