Answer to Question 1

B
Hypotension, the most common complication in barbiturate therapy, results from peripheral vasodilation and can be compounded in an already dehydrated patient who has received large doses of an osmotic diuretic in an attempt to control intracranial pressure. Myocardial depression results from cardiac muscle suppression and can be avoided by frequent monitoring of fluid status, cardiac output, and serum drug levels.

Answer to Question 2

D
Central cord syndrome is associated with cervical hyperextension/flexion injury and hematoma formation in the center of the cervical cord. This injury produces a motor and sensory deficit more pronounced in the upper extremities than in the lower extremities.
