E. Using a circulating warm-water mattress
2. When considering premedication with midazolam in the pediatric patient, all of

intravenous (IV), and rectal routes.
C. As age decreases, required midazolam dose in mg/kg for effective anxiolysis
increases.

The following vignette applies to questions 8, 9, and 10.
A 2-year-old, 12.5-kg girl with history of a ventriculoperitoneal shunt that was
placed in infancy for congenital aqueductal stenosis presents to your OR for
emergent shunt revision in the setting of lethargy, vomiting, and irritability. Her
parents tell you she “ate some crackers” 2 hours ago. The patient is otherwise
healthy with no known drug allergies.

B. Miller 1 blade, size 4.0 cuffed endotracheal tube
C. Miller 1 blade, size 4.5 cuffed endotracheal tube
D. Wis-Hipple 1.5 blade, size 4.0 cuffed endotracheal tube
E. Wis-Hipple 1.5 blade, size 5.0 uncuffed endotracheal tube

infusion at 0.5 μg/kg/h
B. Propofol and fentanyl total IV anesthesia
C. Sevoflurane at 1.0 MAC, oxygen, and air
D. Isoflurane at 1.0 MAC, oxygen, and air
