Answer 1

fewer adverse effects

Question 2

anesthetic effect of inhalants are (more/less) easily controlled

Answer 2

more easily controlled

Question 3

4 factors affecting the uptake of inhalant anesthetics into the blood stream

Answer 3

• anesthetic concentration of inhaled gas
• degree of alveolar ventilation
• cardiac output
• abnormal alveoli

Question 4

a higher heart rate = (faster/slower) absorption of drugs

Answer 4

slower absorption

Question 5

anesthetics mix into the blood and must achieve a threshold concentration before being delivered to the:

Answer 5

CNS

Question 6

blood is a gas solubility _____

Answer 6

coefficient

Question 7

anesthetic drug blood solubilities from most soluble to least soluble: (5)

Answer 7

1. methoxyflurane
2. halothane
3. isoflurane
4. sevoflurane
5. nitrous oxide

Question 8

what does it mean when a drug is more soluble?

Answer 8

more drug is needed to saturate the blood; more drug is needed when going into the bloodstream to saturate the blood to make it to the CNS

Question 9

what does it mean when a drug is not as soluble?

Answer 9

it doesn’t take a lot of the drug to make it to the CNS
