The term WAG refers to:
waste anesthetic gas.
waste agents and gas.
waste analgesic gas.
waste analgesics and gas.
Which of the following general anesthetics are liquids at room temperature?
Nitrous oxide and isoflurane
Isoflurane and sevoflurane
Sevoflurane and nitrous oxide
Nitrous oxide and desflurane
The term REL refers to:
reactive exposure limit.
relative exposure limit.
recommended exposure limit.
redistributed exposure limit.
In regard to the control of WAGs, a scavenging system:
reduces the escape of waste anesthetic gas by leak testing.
leads to less waste pollution by the control of flow rate carrier gas.
controls the waste gas concentration by anesthetic time.
captures waste anesthetic gases by attaching to a machine and discharging them outside the clinic.
Which of the following scenarios would lead to the highest level of waste gas contamination?
A bottle of isoflurane is dropped and broken while refilling the vaporizer.
A fractious cat is “boxed down” in an induction chamber.
A dog is sedated using an anesthesia mask and isoflurane.
A dog is intubated and the endotracheal tube is not inflated prior to the use of isoflurane.
Which of the following is believed to be the least toxic inhalation agent?
Sevoflurane
Isoflurane
Halothane
Methoxyflurane
Short-term problems related to the inhalation of WAGs include symptoms of fatigue, headache, and irritability, due to:
metabolism of the WAGs by the liver.
metabolism of the WAGs by the kidneys.
effect of anesthetic molecules on the brain neurons.
excretion of the WAGs by the kidneys.
The primary function of a scavenging system is to:
provide a professionally installed ASA regulatory system.
collect waste gas from the machine in order for exact analysis.
deliver halogenated anesthetic agents.
collect waste gas from the machine and conduct it to a disposal point outside the building.
The opening through which WAGs exit the pop-off valve on a rebreathing system is:
the waste gas port.
transfer tubing.
the interface.
the gas evacuation system.
The most appropriate type of anesthetic gas evacuation system for a surgical suite 80 feet away from an outside wall is a(n):
passive scavenging system.
active scavenging system.
high-pressure passive scavenging system.
low-pressure active scavenging system.
An activated charcoal canister is least effective at removing which of the following anesthetics?
Nitrous oxide
72 hr of use or weight gain of 100 g.In order to effectively absorb anesthetic vapors, activated charcoal cartridges should be replaced after:
72 hr of use or weight gain of 100 g.
48 hr of use or weight gain of 50 g.
24 hr of use or weight gain of 100 g.
12 hr of use or weight gain of 50 g.
Low-pressure leak tests should be performed how frequently?
monthly

negative-pressure test and high-pressure test
During the use of nitrous oxide as an anesthetic agent, which type of leak test(s) should be performed?
Low-pressure test
Low-pressure and high-pressure tests

Romifidine
Immobilon
Dexmedetomidine
Detomidine
