Medical Pharmacology: General Anesthesia Practice Questions

Properties of inhalational anesthetics:
1. More soluble in blood leads to more rapid induction.
2. Anesthetic tension in the blood rises more rapidly for highly soluble drugs.
3. Brain concentration of nitrous oxide rises rapidly.
4. Rate of pulmonary blood flow significantly affects time to anesthetic equilibrium.
Accepted measure of anesthetic potency.
1. lipid solubility
2. speed of induction.
3. presence of a "second gas effect"
4. minimum alveolar concentration (MAC value)
Unpredictable hepatitis occurrence has been one factor that reduce the use of this inhalational anesthetic:
1. isoflurane
2. enflurane
3. halothane
4. desflurane
Very brief anesthetic effects of this barbiturate is explained by "rapid redistribution":
1. nitrous oxide
2. halothane
3. thiopental
4. fentanyl
Neurolept analgesia:
1. propofol
2. droperidol + fentanyl citrate
3. ketamine
4. enflurane + hydoxyzine
