Answer 4

Desflurane

Question 5

Inhaled anesthetics are myocardial depressants

Answer 5

Enflurane and halothane

Question 6

Answer 6

Fentanyl

Question 7

Benzodiazepine receptor antagonist, it accelerates recovery from benzodiazepine overdose

Answer 7

Flumazenil

Question 8

Inhaled anesthetic that may sensitize the myocardium to arrhythmogenic effects of catecholamines and has produced hepatitis

Answer 8

Halothane

Question 9

Answer 9

Halothane and methoxyflurane

Question 10

Inhaled anesthetic causes peripheral vasodilation

Answer 10

Isoflurane

Answer 17

Nitrous oxide

Question 18

Prolonged exposure to this inhaled anesthetic may lead to megaloblastic anemia

Answer 18

Nitrous oxide

Question 19
