NUR 211 TBI, SCI, and Chronic problems final exam with
correct questions and answers/ NUR 211 TBI, SCI, and Chronic
problems final exam with correct questions and answers
the patient is conscious (awake and aware) but unable to communicate because of severe paralysis -
CORRECT ANSWER-What is a locked-in state?
Positron-emission tomography (PET) and
electroencephalography (EEG) - CORRECT ANSWER-What diagnostic tests are used to support the
diagnosis of PVS?
Glasgow Coma Scale
it measures arousal/eye opening, verbal, and motor responses - CORRECT ANSWER-What is used for a
rapid neurological baseline?
What does it measure?
Best score is 15
Lowest score is 3 (dead person still gets a 3)
< 7 generally indicates a COMA - CORRECT ANSWER-What is the scoring system for GCS?
children, intoxicated patients, and patients with spinal cord injuries - CORRECT ANSWER-GCS is not a
valid measure for what kind of patients?
- nail bed pressure
- trapezius pinch
- sternal rub - CORRECT ANSWER-What are acceptable methods of noxious stimuli?
, - supraorbital pressure
- nipple pinching
- testicle pinching - CORRECT ANSWER-What are unacceptable methods of noxious stimuli?
major brain injury - CORRECT ANSWER-What does decorticate and decerebrate posturing indicate?
acceleration
deceleration
rotational forces - CORRECT ANSWER-What are the 3 types of blunt trauma associated with TBIs?
penetrating and blunt traumas - CORRECT ANSWER-What are the mechanisms of brain injuries?
primary injury (TBI) - CORRECT ANSWER-- initial injury to the brain sustained by impact
- may be mild or severe
EX: contusion, laceration, shearing injuries, and hemorrhage
secondary injury (TBI) - CORRECT ANSWER-- The biochemical and cellular response to the initial
trauma
- Can exacerbate the primary injury and cause loss of brain tissue not originally damaged
ischemia - CORRECT ANSWER-What is the primary culprit in secondary brain injuries?
- hypercapnia which results in cerebral vasodilation and increased cerebral blood volume and ICP
- significant hypotension which causes inadequate perfusion to neural tissue (NOT typical with TBI)
- cerebral edema
- increased ICP with HTN - CORRECT ANSWER-What can occur with a secondary brain injury?
