Answer to Question 1

ANS: B
For MAC, IV sedatives, such as the benzodiazepines, are administered. Therefore the patient needs IV access. Inhaled, epidural, and topical agents are not included in MAC. An occlusive dressing would be placed over a topical agent such as eutectic mixture of local anesthetics (EMLA) cream.

Answer to Question 2

ANS: D
Hallucinations are an adverse effect associated with the dissociative anesthetics such as ketamine. Therefore the postoperative environment should be kept quiet to decrease the risk of hallucinations. Because ketamine causes profound analgesia lasting into the postoperative period, higher doses of analgesics are not needed. Ketamine causes an increase in heart rate. Benzodiazepine may be used with ketamine to decrease the incidence of hallucinations and nightmares.
