Hey guys-
I've been doing some old ITE qns off the ABA site and got stumped on some questions. If someone can help explain a few of these, that would be awesome.
1. An enflurane vaporizer is filled with halothane and the vaporizer dial is set at 1%. Which of the following will occur?
a. less than 1% halothane will be delivered
b. more than 1% halothane will be delivered
c. thymol preparation will prevent vaporization
d. The vaporizer bypass will not open
e. The vaporizer will be damaged
2. Two opened oxygen cylinders, one full and one empty, are attached to the anesthesia machine. The check valve to the empty cylinder fails. This is expected to result in:
a. activation of the fail-safe device
b. cessation of oxygen flow to the anesthesia circuit
c. filling of the empty cylinder with a mixture of all gases supplied to the anesthesia machine
d. increase in the temperature of the empty cylinder
e. interruption of gas delivery from the central oxygen supply
3. Which of the following is the most important function of temperature compensation in anesthestic vaporizers?
a. compensation for changes in the specific heat of the anesthestic during vaporization
b. delivery of diluent gas at a constant temperature regardless of flow rate
c. increase of bypass flow when the vaporizer is cooled by high fresh gas flow
d. maintenance of constant anesthestic vapor output over a range of vaporizer temperatures
e. maintenance of constant vapor concentrations at low flow rates
