b. Heliox therapy d. Aerosol therapy
ANS: C
Hyperbaric oxygen therapy exposes patients to a pressure greater than atmospheric pressure while they breathe 100% oxygen either continuously or intermittently. The effects on lung volume can be explained by Boyle's law, which states that if the temperature of a gas remains constant, the volume of a gas is inversely related to its pressure. That is, as the pressure exerted on the contain-er increase, the gas volume decreases. Thus when a person is exposed to elevated pressures, the gas volume contained in any body cavity tends to be compressed.

Your patient is a 44-year-old female who is alert and in mild distress. She states that she had an acute onset of sharp, right lower quadrant abdominal pain last evening while having intercourse and that the pain has not subsided. She states the pain radiates to her lower back and rates it as a 5 on a scale of 1–10. Physical examination reveals tenderness with palpation to the lower right
abdominal quadrant, and her skin is warm and dry. HR = 100, RR = 12, BP = 116/78. Her last menstrual period was three weeks ago, she had a tubal ligation ten years ago and she states she has several small fibroid tumors. Which of the following is the most likely diagnosis for this patient? A) Ectopic pregnancy B) Pelvic inflammatory disease C) Mittelschmerz D) Ruptured ovarian cyst
