(B) Meperidine
(C) Midazolam
(D) Morphine
(E) Sufentanil

Which of the following findings necessitates the preoperative insertion of a ventricular pacemaker in a 48-year-old man scheduled to undergo cholecystectomy?

(A) Atrial flutter with 3:1 atrioventricular block
(B) Bifascicular (right bundle branch block and left anterior hemiblock) block
(C) Left bundle branch block with first-degree atrioventricular block

ADVANCED Cardiac

Which of the following is the most important factor affecting the incidence of postoperative pulmonary complications?

(A) Age of the patient
(B) Anesthetic technique
(C) Duration of surgery
(D) Obesity
(E) Site of the operation

An 80-kg, 70-year-old woman is scheduled for a mastectomy. She has a history of congestive heart failure treated with digoxin 0.25 mg daily. Preoperative examination shows a sinus rhythm at 80 bpm and blood pressure of 110/70 mmHg. Laboratory studies show a serum potassium concentration of 4.2 mEq/L and a serum digoxin concentration of 1.5 mcg/ml. Five minutes after induction of general anesthesia, ventricular bigeminy is noted; blood pressure is 85/65 mmHg, SpO2 is 97%, and PetCO2, is 20 mmHg. Which of the following is the most appropriate management?

(A) Administration of calcium chloride
(B) Administration of ephedrine
(C) Administration of lidocaine
(D) Administration of potassium chloride
(E) Decrease in ventilation

ADVANCED General

Compared with the adult airway, the airway of an infant is characterized by

(A) greater narrowing at the cricoid ring
(B) a less rigid epiglottis
(C) a more caudad laryngeal opening
(D) a relatively smaller tongue
(E) relatively larger tonsils

ADVANCED Pediatric

During frontal craniotomy for removal of an astrocytoma, the surgeon notes that the brain is "tight." The patient is receiving nitrous oxide 50% in oxygen, isoflurane 0.5%, fentanyl, and pancuronium. Heart rate is 92 bpm, blood pressure is 110/60 mmHg, end-tidal carbon dioxide tension is 31 mmHg, and oxygen saturation is 98%. The most appropriate initial treatment is to

(A) administer a beta-adrenergic blocker
(B) administer thiopental
(C) decrease isoflurane concentration
(D) decrease mean arterial pressure to 60 mmHg
(E) increase alveolar ventilation

Each of the following statements concerning the activated clotting time (ACT) is true EXCEPT:

(A) The ACT is more sensitive than the activated partial thromboplastin time (APTT) to blood heparin concentration
(B) The ACT is prolonged if the specimen is not warmed during the assay
(C) The ACT should be greater than 300 sec before initiating cardiopulmonary bypass
(D) Hypofibrinogenemia may prolong the ACT after cardiopulmonary bypass
(E) Whole blood is used for measurement of the ACT

ADVANCED General Cardiac

Increasing preload, systemic vascular resistance and heart rate will best maintain hemodynamic stability in patients with

(A) aortic stenosis
(B) asymmetric septal hypertrophy (IHSS)
(C) cardiac tamponade
(D) mitral regurgitation
(E) mitral stenosis

BASIC Cardiac

After removing the electrocautery pad from the thigh, a burn is noted at that site. Which of the following most likely contributed to this injury?

(A) A line-isolation monitor fault
(B) Current leak from the EKG module
(C) Defective grounding of the electrocautery unit
(D) Dried gel on the electrocautery pad
(E) Excessive current setting for cutting mode

BASIC Equipment & Physics

A patient is anesthetized using an inhaled anesthetic with a blood/gas partition coefficient of 13.0. Recovery time depends primarily on

(A) oil/gas solubility of the drug
(B) cardiac output
(C) tidal volume
(D) duration of administration
(E) MAC of the drug
