Coma

Question 1

Stupor

Answer 1

-sleep-like state from which pt can be aroused only by vigorous stimuli

Question 2

Coma

Answer 2

-sleep-like state where pt is unresponsive to external stimuli, and there are no sleep/wake cycles

Question 3

Decorticate Posturing

Answer 3

• flexion
• upper extremity flexion with lower extremity extension
• suggests lesion at hemispheres

Question 4

Decerebrate Posturing

Answer 4

• extension
• upper extremity extension with lower extremity extension
• suggests lesion at brainstem
• worse prognosis than with decorticate posturing

Question 5

Vegetative State

Answer 5

• where sleep/wake cycles re-establish but there is no sign of cognitive function
• thalamus damage

Question 6

Brain Death Criterion

Answer 6

• unresponsiveness
• cerebrally modulated motor responses are absent during application of painful stimuli
• brainstem reflexes are absent
• core body temp of 32.2 C of higher
• toxicology tests find no explanation
• adequate BP and pulse
• no voluntary movements

Question 7

Minimally Conscious State

Answer 7

• eyes open spontaneously
• sleep/wake cycles resume
• there are reproducible, though inconsistent, behavioral displays of perception, communication, or purposeful motor activity

Question 8

Hypoxic Ischemia Coma

Answer 8

• due to lack of blood supply or oxygen to the brain

- outcome is often worse than from trauma
