NAUI NITROX DIVER FINAL EXAM
QUESTIONS AND ANSWERS
3.9 ata -Answer-What is the partial pressure of nitrogen in air at 40 msw (130 fsw)?
False -Answer-True or False. Narcosis is reduced significantly when diving with
enriched air nitrox.
Anesthesia -Answer-The mechanisms of nitrogen narcosis are thought to be similar
to:
Metabolism -Answer-Oxygen is used by the body in:
Hypoxia -Answer-The term used for low oxygen in the body is:
Convulsions -Answer-Breathing high partial pressures of oxygen can cause:
1.4 ata -Answer-The accepted oxygen partial pressure exposure limit for recreational
nitrox diving is:
Terminate the dive. -Answer-At the first signs or symptoms of oxygen toxicity, a diver
should:
32% oxygen and 36% oxygen -Answer-Historically, what are the two standard nitrox
mixes?
EAN38 -Answer-What is the "best mix" to use for an oxygen partial pressure limit of
1.4 ata on a dive to 27 msw (90 fsw)?
300 meters (1000 feet) -Answer-Standard NAUI Dive Tables can be used for
altitudes up to about:
610 meters (2000 feet) -Answer-NAUI RGBM sea level Dive Tables can be used for
altitudes up to:
+/- 1% -Answer-The NAUI EAN32 and EAN36 Dive Tables have a tolerance of
_____ of the tables' value.
36 minutes -Answer-Using the NAUI EAN32 Dive Tables, a diver makes a dive to 33
msw (110 fsw) for 20 minutes. After a surface interval of 2 hours, the diver makes a
second dive, also on EAN32 to a depth of 20 msw (65 fsw). What is the diver's
maximum dive time for the second dive?
60 minutes -Answer-If the same diver in question 30 were using NAUI RGBM EAN32
Dive Tables, what would be his maximum dive time for the second dive?
EAN32 and EAN36 -Answer-NAUI Nitrox Dive Tables and NAUI RGBM Nitrox Dive
Tables are available for:
