Answer to Question 1

C
The third cranial nerve runs parallel to the brain stem. The function of the oculomotor nerve is essential for eye movements. A traumatic brain injury can result in increased intracranial pressure, edema to the brain stem with pressure on cranial nerve III, causing the ominous sign of a unilateral, dilated, and nonreactive pupil.

Answer to Question 2

B
Tetany and muscle weakness, tachypnea, and cardiac arrhythmias are symptomatic of respiratory alkalosis.
