(A) amitriptyline
(B) atropine
(C) diphenhydramine
(D) promethazine
(E) ranitidine

A 1100-g, 10-day-old infant is to undergo ligation of a patent ductus arteriosus after unsuccessful medical treatment. Within three minutes of intravenous administration of atropine 20 mcg, fentanyl 20 mcg, and pancuronium 0.1 mg, systemic blood pressure decreases from 80 to 30 mmHg, heart rate from 180 to 140 bpm, and arterial oxygen saturation from 90% to 80%. The most appropriate management is to

(A) increase FiO2
(B) administer additional atropine
(C) infuse crystalloid
(D) infuse prostaglandin E1
(E) administer phenylephrine

ADVANCED Pediatric Cardiac

A patient receiving propranolol and nifedipine is scheduled for elective coronary artery bypass surgery. During induction with fentanyl and oxygen, heart rate decreases from 52 to 36 bpm and blood pressure decreases from 130/85 to 80/50 mmHg. Administration of atropine 2 mg intravenously has no effect. The most appropriate treatment at this time is administration of

(A) epinephrine
(B) pancuronium
(C) naloxone
(D) phenylephrine
(E) calcium chloride

ADVANCED Cardiac

Which of the following is the most likely cause of dyspnea during spinal anesthesia to a T3 sensory level?

(A) Decreased abdominal muscle tone
(B) Decreased afferent input from the thoracic wall
(C) Increased dead space ventilation
(D) Increased intrapulmonary shunting
(E) Partial diaphragmatic paralysis
