Sample Questions

Question 1
Which gas law best describes why an undrained pneumothorax is an absolute contraindication to hyperbaric oxygen therapy?
Boyle's law — gas volume is inversely proportional to pressure, so trapped gas expands during decompression
Dalton's law — the total pressure of a gas mixture equals the sum of partial pressures
Henry's law — gas dissolves in liquids in proportion to partial pressure
Charles's law — gas volume is directly proportional to absolute temperature
Question 2
A diver descends to 33 feet of seawater (fsw). What is the approximate absolute ambient pressure?
2 atmospheres absolute (ATA)
1 ATA
3 ATA
0.5 ATA
Question 3
According to Dalton's law, what is the partial pressure of oxygen (PO2) when breathing 100% oxygen at 2.4 ATA?
2.4 ATA (1,824 mmHg)
0.21 ATA
1.0 ATA (760 mmHg)
2.0 ATA
Question 4
Which gas law explains the uptake of nitrogen into tissues during a dive (nitrogen saturation) and its subsequent release leading to decompression sickness?
Henry's law — the amount of gas dissolved in a liquid is proportional to its partial pressure above the liquid
Boyle's law — volume and pressure are inversely related
Graham's law — rate of diffusion is inversely proportional to the square root of molecular weight
Charles's law — volume and temperature are directly related at constant pressure
Question 5
Which of the following is NOT currently among the 14 UHMS-approved indications for hyperbaric oxygen therapy?
