A) inversely proportional to volume B) nearly proportional to its absolute temperature C) inversely proportional to the absolute mass D) the sum of the partial pressures exerted by the individual gasses in the mixture - ANSWER Answer D) 9) The largest percentage of the dry atmospheric composition is A)oxygen B)carbon dioxide C)nitrogen D)hydrogen - ANSWER Answer C) 10) Boyle's law - ANSWER Volume of a gas is inversely proportional to it's temperature remaining constant. 11) Charles Law - ANSWER Volume of gas is proportional to it's absolute temperature. If temperature affects volume. Or C for cold 12) Universal Gas Law - ANSWER Combination of Charles and Boyle's gas laws. Explains relationship between volume, pressure and temperature. 13) Dalton's Law - ANSWER The total pressure of a gaseous mixture is equal to the sum of the partial pressures in the liquid. Or "T" for total pressure Barometric pressure + gas partial pressure 14) Name four types of hypoxia - ANSWER Hypoxic hypoxia Hypemic hypoxia Stagnant hypoxia Histotoxic hypoxia 15) Hypoxic hypoxia is - ANSWER inadequate gas exchange at the alveolar capillary membrane 16) Stagnant hypoxia - ANSWER circulatory insufficiency reduces oxygen delivery to tissues 17) Histotoxic Hypoxia - ANSWER When tissues are unable to utilize oxygen delivered to them. Think ETOH, narcotics, etc. 18) Eye trauma reduce altitude to? - ANSWER 1000 ft 19) Altitude Epiglottis - ANSWER 3000 20) Altitude CNS - ANSWER 2000 21) Altitude CVS - ANSWER 2000 22) Altitude respiratory - ANSWER 2000 23) COPD and GI system altitude - ANSWER 24) Altitude in Reproductive, MSI, Skin - ANSWER 4000 25) Dalton's law applies to mainly: A) pressure B) volume C) temperature D) mass - ANSWER A) pressure 26) Dalton's law states "the total pressure of a mixture of gases equal..." A) inverse proportional to volume B) nearly proportional to its absolute temperature C) inversely proportional to the absolute mass D) the sum of the partial pressures exerted by the individual gases in the mixture - ANSWER D 27) The largest percentage of the dry atmospheric composition is: A) oxygen B) carbon dioxide C) nitrogen D) hydrogen - ANSWER C) nitrogen 28) To calculate the partial pressure of a gas rate at a certain altitude, the following points must be known: A) barometric pressure and temperature B) barometric pressure and rate of ascent C) temperature and gas concentration D) gas concentration and barometric pressure - ANSWER D) gas concentration and barometric pressure 29) According to Dalton's law, hypoxia results at high altitudes because: A) decreased temperature make oxygen less available B) as barometric pressure decreases, oxygen concentration decreases. C) while oxygen concentration remains unchanged, decreased partial pressure makes is less available. D) barometric pressure increases therefore oxygen is also at a higher pressure. - ANSWER C) while oxygen concentration remains unchanged, decreased partial pressure makes is less available. 30) The time of useful consciousness (TUC) is (shorter/longer) at higher altitudes. - ANSWER Shorter 31) The average time of useful consciousness for depressurization at 25,000ft is: A) 30-60 seconds B) 90 seconds C) 3-5 minutes D) 30 minutes - ANSWER C) 3-5 minutes 32) Which of the following factors contribute to hypoxia in the air medical crew: eating gas forming food length of time at altitude general health status/level of fitness noise intensity 100 db A) 1,2,3 B) 2,3 C) 2,4 D) all of the above - ANSWER D 33) Which of the following is true of Boyle's law? A) the reduction of temperature will cause reduction in pressure. B) there is a reduction in volume when pressure falls C) gas evolves from solution, resulting in hypoxia D) gas volume increases as pressure decreases - ANSWER D) gas volume increases as pressure decreases 34) By 18,000 ft ASL, what volume would you expect a 10ml cuff on an ETT tube to expand to? - ANSWER 20 ml 35) Henry's law: True/ False Temperature and pressure are related inversely. - ANSWER False 36) Henry's law: True/ False Gas remains in solution relative to the pressure of gas around the solution. - ANSWER True 37) Henry's law: True/ False Decompression sickness can be explained by the principles of Henry's law. - ANSWER True
