Answer to Question 1

C
Propofol is an effective short-term anesthetic agent, useful for rapid wake-up of patients for assessment; if continuous infusion is used for many days, emergence from sedation can take hours or days; sedative effect depends on the dose administered, depth of sedation, and length of time sedated.

Answer to Question 2

D
Capillary refill assessment is a maneuver that uses the patient's nail beds to evaluate both arterial circulation to the extremity and overall perfusion. The severity of arterial insufficiency is directly proportional to the amount of time necessary to re-establish flow and color.
