      Liquid that has a tendency to change to a vapor at standard temperature and pressure

    Correct Answer
    D. Liquid that has a tendency to change to a vapor at standard temperature and pressure
    Explanation
    A volatile anesthetic agent refers to a liquid substance that has a tendency to change into a vapor form at standard temperature and pressure. This means that the molecules of the liquid have a high vapor pressure, causing them to easily evaporate and form a gas. This property is crucial in anesthesia as it allows the agent to be easily inhaled and distributed throughout the body, inducing and maintaining a state of unconsciousness during medical procedures.

    • C.

      Passing gas over the liquid

    • D.

      All of the above

    Correct Answer
    B. Heating
    Explanation
    Heating increases the SVP (Saturation Vapor Pressure). When a substance is heated, its molecules gain energy and move faster, causing an increase in the rate of evaporation. This leads to an increase in the number of molecules in the gas phase, resulting in a higher vapor pressure. Therefore, heating can increase the SVP of a substance.

    What decreases SVP choose all that apply?

    • A.

      Cooling

    • B.

      Heating

    • C.

      Passing gas over the liquid

    • D.

      All of the above

    Correct Answer(s)
    A. Cooling
    C. Passing gas over the liquid
    Explanation
    Cooling decreases the saturation vapor pressure (SVP) because it lowers the temperature, reducing the energy of the water molecules and decreasing their ability to escape into the gas phase. Passing gas over the liquid also decreases SVP as it increases the concentration of gas molecules above the liquid, reducing the chances of water molecules escaping into the gas phase. However, heating increases the SVP as it raises the temperature, increasing the energy of the water molecules and promoting their transition into the gas phase. Therefore, heating does not decrease SVP.

    Why does heat need to be supplied to the liquid anesthetic? choose all that apply

    • A.

      To maintain a constant temperature

    • B.

      To decrease SVP

    • C.

      To keep a constant SVP

    • D.

      To operate the bellows

    Correct Answer(s)
    A. To maintain a constant temperature
    C. To keep a constant SVP
    Explanation
    Heat needs to be supplied to the liquid anesthetic to maintain a constant temperature because anesthetic agents are volatile and can evaporate easily. By supplying heat, the temperature of the liquid anesthetic can be controlled, ensuring that it remains at the desired level for administration. Additionally, heat is required to keep a constant saturated vapor pressure (SVP) of the anesthetic. This is important because the SVP determines the concentration of the anesthetic vapor in the gas mixture delivered to the patient. By maintaining a constant SVP, the anesthetic concentration can be accurately controlled.

    • D.

      All of the above

    Correct Answer(s)
    A. The use of a valve to change flow based on temperature
    C. Temp compensating bypass
    Explanation
    Thermocompensation is regulated through the use of a valve to change flow based on temperature and a temp compensating bypass. By using a valve, the flow of a substance can be adjusted based on the temperature, ensuring that the system remains regulated. Additionally, a temp compensating bypass can be used to maintain a consistent temperature by diverting excess heat or cold away from the system. Therefore, both options mentioned in the answer are correct methods of regulating thermocompensation.
