Which of the following complications is more likely to occur during cannulation of the left internal jugular vein than during cannulation of the right internal jugular vein?
An obese, 35-year-old man had an episode of coughing followed by vomiting during induction of anesthesia for arthroscopy of the left knee. Intense wheezing developed bilaterally over five minutes. PaO2 is 60 mmHg, PaCO2 is 42 mmHg, and pH is 7.35. Optimal management following intubation of the trachea includes
(A) mechanical ventilation with positive end-expiratory pressure (PEEP), cancellation of surgery, and transfer to the intensive care unit
(B) saline lavage and continuation of surgery using halothane anesthesia
(C) cancellation of surgery and administration of corticosteroids and antibiotics
(D) thorough suctioning and proceeding with halothane anesthesia
(E) cancellation of surgery, vigorous mechanical ventilation, thorough suctioning, and administration of aminophylline
Which of the following is the most likely cause of postural headache following spinal anesthesia?

(B) administration of a beta-adrenergic blocker
(C) administration of lidocaine

During total cardiopulmonary bypass, metabolic acidosis and decreasing mixed venous oxygen saturation are noted. The most likely cause is
A woman is undergoing a repeat cesarean delivery at term following a normal pregnancy. Anesthesia consists of thiopental 250 mg, succinylcholine infusion (180 mg in 20 minutes), nitrous oxide and oxygen (7:3 L/min) until delivery. Twenty minutes after the incision a floppy newborn with a 1-minute Apgar score of 5 is delivered. The most likely explanation for the infant's condition is
