ADVANCED Pediatric Cardiac

Which of the following statements concerning successful blockade of the femoral nerve is true?

(A) It requires that a paresthesia be elicited prior to injection
(B) It provides motor blockade below the knee

Desflurane is delivered using a vaporizer that contains internal heaters because

(A) heat decreases the drug's viscosity
(B) heat reduces thermal loss in the patient

BASIC Pharmacology & Pharmacokinetics

Trimethaphan causes each of the following EXCEPT

(A) cerebral vasodilation
(B) urinary retention
(C) pupillary cycloplegia
(D) histamine release
(E) potentiation of succinylcholine block

BASIC Pharmacology & Pharmacokinetics

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

BASIC General

Which of the following decreases the risk for burns during electrocauterization?

(D) Isolation of the current output of the electrosurgical unit
(E) Placement of the return electrode at a distance from the surgical site

BASIC Equipment & Physics

A patient who is scheduled for a parathyroidectomy for a parathyroid adenoma has a preoperative serum calcium concentration of 13.5 mg/dl. The ECG shows no acute changes. The most appropriate preoperative management is administration of

(C) intravenous saline solution
(D) mannitol
(E) potassium phosphate
