| Question | Answer |
| When the oxygen tank is half full, the tank pressure gauge will read approximately: | 1100 psi |
| the pressure gauge of a nitrous oxide tank will read _____ psi when the tank is full: | 760 |
| When the nitrous oxide tank is half full, the pressure gauge will read _____ psi. | 760 |
| Nitrous oxide is present in the tank as a ______. | Liquid and a gas. |
| The amount of oxygen an animal is receiving is indicated by the: | Flowmeter |
| Flowmeters that have a ball for reading the gauge should be read from the _____ of the ball. | Middle |
| The most common recommended ratio for nitrous oxide and oxygen flow rates is: | 33% oxygen and 67% nitrous oxide |
| The minimum size for the reservoir bag can be calculated as________. | 60ml/kg |
| The flutter valves on an anesthetic machine help ______. | Control the direction of movement of gases. |
| The pop-off valve is part of the anesthetic machine and helps: | Prevent excess gas pressure from building up within the breathing circuit. |
| In small animal anesthesia, when the pressure manometer reading exceeds _____ cm of water pressure, it indicates there is a buildup of pressure within the circuit that could be dangerous. | 15 |
| Rebreathing systems are best reserved for animals over 7kg. True or False? | True! |
| Rebreathing is determined primarily by the: | Fresh gas flow. |
| Nonrebreathing systems should have maintenance flow rates that are: | Very high (130 ml/kg/min) |
| The negative pressure relief valve is particularly useful when: | There is a failure of oxygen flow through the system. |
| The tidal volume of an animal is considered to be ________ ml/kg of body weight. | 10-15 |
| A reservoir bag that is not moving may indicate: | The endotracheal tube is not in the trachea; The animal has a decreased tidal volume; There is a leak around the endotracheal tube. |
| The anesthetist will know when the granules in the carbon dioxide absorber have been depleted because the: | Granules will be brittle; Granules may change color; Granules may be hard. |
| An increase in the depth of anesthesia can be achieved quickly by: | Having high oxygen flow rates; Having high vaporizer settings; Bagging the animal with the precision vaporizer at a higher setting. |
| The concentration of anesthetic delivered from a nonprecision vaporizer may depend on the: | Temperature of the liquid anesthetic; Flow of the carrier gas through the vaporizer; Back pressure; Type of anesthetic in the vaporizer. |
| The advantage of a nonprecision vaporizer include: | It is economical to buy; It is easy to clean and service. |
| Low flow anesthesia means: | Using flows that only meet the metabolic requirements of the animal on oxygen. |
| The disadvantages of low flow anesthesia include: | It may allow carbon dioxide to accumulate in the circuit; It is difficult to use with nitrous oxide. |
| Using special techniques, nonprecision vaporizers can be used for: | Low flow anesthesia; Delivery of isoflurane. |
| Waste anesthetic gases are a potential hazard to personnel, but problems that arise are really only of a short term nature. True or False? | False! |
| Long-term toxicity of inhalation anesthetics is thought to be caused by the release of toxic metabolites during the breakdown of these drugs. True or False? | True! |
| The anesthetic thought to be the least toxic to hospital personnel is: | Isoflurane |
| In the US, the NIOSH recommends that the levels of waste anesthetic gases for anesthetics such as isoflurane, halothane or methoxyflurane should not exceed _______ ppm. | 2 |
| The odor of halothane may be detected by a person when the levels reach a minimum of ______ ppm. | 33 |
| Rooms in which animals are recovering from anesthesia may be highly contaminated with waste gas. True or False? | True! |
| It is recommended that for a passive scavenger system, the hose be no longer than _____ feet if it discharges into the room ventilation exhaust. | 10 |
| How often should a test for low pressure leaks be conducted? | Each time the machine is used. |
| The safest way to transport a high pressure tank such as an oxygen tank, is by: | A handcart |
| Rooms in which waste anesthetic gases are at risk of being released should have a minimum of _____ air changes per hour. | 15 |
| Long term hazards that may occur from exposure to high levels of anesthetic waste gases include: | Reproductive disorders; Liver damage; Kidney damage and Nervous system dysfunction. |
| A technician may reduce the amount of waste gases by: | Using a cuffed endotracheal tube; Ensuring the anesthetic machine has been tested for leaks; Using an induction technique other than mask or chamber. |
| To conduct a low pressure test on an anesthetic machine (circle system), you must: | Close the pop-off valve and occlude the end of the circuit; Compress the reservoir bag; Pressurize the circuit with a volume of gas. |
