quiz Flashcards
2 first steps in spinal cord injury
2 other steps
Immobilization and stabilization of the head (collar)
assessment of airway and breathing
initial tx for injury above T4
intubation
symptoms of spinal shock 2 and the tx
(hypotension, bradycardia)
1st: ), fluid resuscitation with crystalloid fluids and atropine
2nd: vasopressors
what is autonomic dysreflexia
where
symptoms 5
assessment
complication of spinal cord injury
sudden onset of very high blood pressure caused by bladder or bowel distention
usually in t6 or above
headache, flushed face, sweating above the level of injury/cool, clammy skin below, bradycardia
assess for retention of urine (bladder scan and bladder program)
2 complications of spinal cord injury
autonomic dysreflexia , immobility
monroe kellie hypothesis
Intracranial Volume (VIC) = volume of the brain + volume of blood + volume of CSF + volume of the lesion. – if one is off it throws others off
compliance
balancing act of keeping ICP 5-15
CPP formula, what does it determine, normal, what happens when MAP is decreased and ICP is increased
CPP DETERMINES BRAIN O2
MAP-ICP
60-65
decreased perfusion
3 things assessed in GCS- whats normal, mod, severe
eye opening, motor response, verbal response
13-15 = normal/mild injury,
9-12 = moderate injury,
8 or less, severe injury/coma
how to assess ICP 5
GCS
positioning- decorticate, decerebrate
pupillary response
babinski (if toes expand =abnormal)
cranial nerve assessment
pupillary response - dolls eye damage to
CN 2
hearing problems is what CN
CN VIII
tumor of CNVIII
acoustic neuroma
cough, gag reflex tests what CN
CN IX and X
dolls eye abormal finding
eyes dont move
cold caloric test normal finding
eyes go to ear with cold fluid
ABC waves on ICP monitor
A waves: PROBLEM (50-100) – lasts 5-20 minutes with a rapid onset
B waves: 20-50 ICP increase not an emergency – B waves usually before A waves (example is when they get suctioned after they already have high ICP)
C waves: NORMAL up to 20 – no problem
7 nursing responsibilities of ICP monitoring with device
- NEURO CHECKS HOURLY
- Monitor ICP, MAP, and CPP at least hourly.
- Monitor the effects of nursing care (repositioning, suctioning, etc.) on the patient’s ICP.
- Validate accuracy of waveforms and values.
- Maintain strict aseptic technique (infection is the primary complication of ICP monitoring).
- Ensure the dressing site is clean, occlusive, and dry.
- Assess the system for leaks of CSF.(yellow and clear)
gliomas vs mengiomas
Gliomas – malignant
Meningiomas – benign
tumor prognosis depends on
how fast and big tumor grows - even benign tumors can be fatal depending on location and speed bc they increase ICP
risk factors for brain tumors 3
inherited disease
enviornment
radiation
when does cerebral edema occur in brain tumors
1mm tumor size
what are brain tumor symptoms related to
SIZE
focal symptoms of brain tumors 8
ringing in the ears,
hearing problems/loss,
decreased muscle control,
lack of coordination,
decreased sensation,
weakness or paralysis,
difficulty with walking or speech double vision.
main pharm tx of brain tumors
glucocorticoids to decrease tissue swelling
initial tx for meningiomas tumors
surgery
dexamathasone
indication
MOA
nursing resp 3
9 SE
indicated for patients with symptomatic cerebral edema from brain tumors
It produces a reduction of cerebral edema and symptoms within 8-48 hours of first dose and effects can last as long as 72 hours.
monitoring for side effects
adjusting dose to the min needed
taper off
insomnia, visual blurring, tremor, behavioral changes, increased appetite, weight gain, hyperglycemia, hypertension, and muscle weakness in the legs.
most common cause of TBI
blunt trauma with falls most common
when is CT indicated in TBI
for minor injuries (like concussions) they are not evidence-based. They are helpful in more severe injuries, older patients, and those on anticoagulants.
if change in VS where is brain injust
brainstem - medulla
linear skull fracture
nondisplaced fracture as a result of low-impact.
