Question 3

This is the only white liquid that can be given IV

Answer 3

Propofol

Question 4

True or false: Propofol has a rapid onset, long duration of action due to it being low in fat solubility

Answer 4

False; it has a shot duration of action due to it being highly fat soluble

Question 5

True or false: Propofol is rapidly metabolized, rapid recovery, and minimal residual sedative effects even after repeated doses

Answer 5

True
