Q

This injectable anesthetic agent can be used for sedation, induction and maintenance of anesthesia. It is NOT a DEA controlled substance and does NOT offer analgesia. It is a potent respiratory depressant and rapid injection or high doses can result in life threatening apnea

Q

Propofol enters the brain quickly because

A

the brain is part of the vessel-rich group of tissues.

propofol is lipid soluble and its entry into the brain is enhanced by the high lipid content of the brain.

17
Q

What is the term for a breathing pattern in which there is a pause for several seconds at the end of the inspiratory phase, followed by a short, quick expiratory phase

A

apneustic respiration

18
Q

The lowest tissue for redistribution/lowest blood flow is

A

fat

19
Q

This has the most commonly used inhalant agent in North America

A

isoflurane

20
Q

Has the highest percentage of metabolism by the liver

A

sevoflurane

21
Q

Highest MAC

A

nitrous oxide

22
Q

Can react with exhausted carbon dioxide absorber granules and has the greatest tendency to produce carbon monoxide

A

desflurane

23
Q

Has a usual maintenance vaporizer setting between 1.5% and 2.5%

A

isoflurane

24
Q

Has the lowest percentage of metabolism by the liver

A

nitrous oxide

25
Q

This agent has the highest vaporizer setting and requires an electronic heated vaporizer

A

desflurane

26
Q

This halogenated organic compound is best suited to be used for mask or chamber anesthesia induction

A

sevoflurane

27
Q

The modern halogenated inhalation agents have a high vapor pressure. This means

A

they commonly are administered through a precision vaporizer.

if their delivery is not controlled, they could reach a delivery percentage of greater than
30% which could prove fatal to patients.

they easily evaporate from a liquid to a gas

28
Q

The ability of an inhalation agent to pass through the alveoli of the lung to the blood
stream is related to the…

A

concentration gradient of the agent in the alveoli

lipid solubility of the agent

29
Q

The lower the partition coefficient is for an anesthetic means that the agent is better at dissolving in alveolar gas. Therefore, those agents that have lower partition coefficients…

A

have a faster induction to maintenance anesthesia and a faster recovery

30
Q

An inhalation anesthetic agent with a higher MAC value will have

A

a higher precision vaporizer setting for induction and maintenance
