39

What is considered a "stupor"?

patient aroused with painful stimuli ; minimal awareness of self and environment

40

a patient that opens eyes and looks at you, but responds slowly and is somewhat confused; alertness and interest are decreased -- is considered to be what?

obtunded - aroused with gental shaking

41

how are motor and sensory tested for the trigeminal nerve?

motor is teeth clenching; sensory is done with sharp and dull alternating over branches of the nerve

42

Which nerves are tested when testing pupil is direct and consensual response to light

CN III, IV, VI (oculomotor, trochlear, facial)

43

Which nerve is tested by the Weber and Rene tests?

vestibulocochlear n.

44

how is muscle strength graded?

Graded on a scale from 0 to 5 0 = no muscular contraction 3 = active movement against gravity 5 = active movement against resistance (normal)
