Answer to Question 1

ANS: C
The brain receives approximately 20 of the cardiac output.

Answer to Question 2

ANS: C
In evaluating the oculomotor nerve, the pupils are examined for size, shape, and equality; pupil-lary reflex tested with a pen light (pupils should constrict when illuminated); and ability to follow moving objects. The olfactory nerve is assessed using smells. The vagus nerve is assessed using the ophthalmoscope. The trigeminal nerve is assessed with a safety pin and hot and cold objects for sensations of pain, touch, and temperature.
