2.   ?    12 hours
3.   ?    None
4.   ?    16 hours

One symptom of air embolisms is:

The areas commonly affected by barotrauma of descent are:

1.   ?    The eustachian tube and heart
2.   ?    The middle ear and otic canal
3.   ?    The liver and kidneys
4.   ?    The middle ear and brain

A good sign that a wound was caused by sea urchin spines is:

1.   ?    A laceration
2.   ?    A purple stain on or around the wound

DAN is an acronym for:

1.   ?    Diver`s Alert Network
2.   ?    Diver`s Air Network
3.   ?    Destroy And Notate
4.   ?    None of these

The reason nitrogen is such a problem in decompression sickness is:

1.   ?    It is not metabolized in the body
2.   ?    Nitrogen narcosis
3.   ?    It does not dissolve
4.   ?    Methylhemoglobinemia

The rupture of the alveoli and the filling of the extraalveolar spaces with air is:

1.   ?    Positive Pressure Syndrome
2.   ?    POPS
3.   ?    Decompression sickness
4.   ?    Always fatal

The venom contained in stingray barbs is:

1.   ?    Cardiopathetic
2.   ?    Cardiotoxic
3.   ?    Painless
4.   ?    None of these

If the bubbles from air embolism lodge in the brain they can cause:

1.   ?    Ventricular fibrillation
2.   ?     Ischemia and infarction
3.   ?    Subcutaneous emphysema
4.   ?    Decompression sickness

When treating a patient for near drowning, to help drainage, place the patient:

1.   ?    On their side
2.   ?    On their stomach
3.   ?    With legs elevated
4.   ?    Into the water

As a diver descends:

1.   ?    The air within the lungs becomes less dense
2.   ?    The air within the lungs is compressed
3.   ?    The air within the lungs expands
4.   ?    The air within the lungs changes chemical composition

Near-drowning is the survival from being submerged in water for at least:

1.   ?     20 hours
2.   ?    24 times
3.   ?    24 minutes
4.   ?    24 hours

When assessing a hypothermic patient, use the A B C D`s, the D stands for:

1.   ?    Disability
2.   ?    Determination of cause
3.   ?    Degree of hypothermia
4.   ?    Diagnosis

The percent of nitrogen in the air is:

1.   ?    25%
2.   ?    Twice that of oxygen
3.   ?    7%
4.   ?    78%

Warming fluids should be given orally to a hypothermic patient if:

1.   ?    The patient is able to swallow and protect his airway
2.   ?    Only for decompression illness
3.   ?     The core temperature is below 88
4.   ?    None of these

From a prehospital perspective, the treatment for Decompression Illness is:

1.   ?    Lithotripsy
2.   ?    Mainly supportive, evacuate
3.   ?    Barotrauma
4.   ?    MAST trousers

Nematocysts should be rinsed off with:

1.   ?    Alcohol
2.   ?    Gasoline
3.   ?    Sea water
4.   ?    Ice water

If air evacuation is performed for a patient with possible decompression illness, the aircraft should fly lower than:

1.   ?    120 ft
2.   ?    70 ft
3.   ?    1000 ft
4.   ?    500 ft

The pressure on an object in 33 ft of water is:

1.   ?    25 p.s.i.
2.   ?    Less than that at the surface
3.   ?    33 atmospheres
4.   ?    2 atmospheres

Three signs of Decompression Sickness are:

1.   ?    Hallucinations, a migraine-like headache, partial deafness
2.   ?    Severe, deep aching pain in the muscles, joints, and tendons, numbness or weakness, itching
3.   ?    Blotchy rash, paralysis, coughing spasms
4.   ?    Low PCO2, high pulse oximetry reading, gastric distension
