Neuro Flashcards
Hypertension, bradycardia, and respiratory depression are called what? What is this a sign of?
Cushing’s reflex; elevated intracranial pressure
A 23 year old man who comes into the ER after a blunt head trauma in MVA with progressive drowiness, weakness on the right side of body, and a change in BP from 95/80 to 160/90 and change of pulse from 120 to 50 indicates what neurological issue?
Uncal herniation caused by elevated cerebral pressure from epidural hematoma
Ipsilateral hemiparesis, ipsilateral mydriasis, ptosis, contralateral homonymous hemianopsia, and altered LOC are signs of what?
Uncal herniation
When is the Rinne test normal? Abnormal?
air conduction is heard twice as long as bone conduction when vibrating fork goes near external auditory meatus. Abnormal when BC is greater than AC, indicating a conductive hearing loss
This is considered when during the Weber test, the vibration lateralizes to the unaffected ear because the affected ear can’t sense the vibration; and during the Rinne, AC is greater than BC in both ears
sensorineural hearing loss
This is used to treat early Parkinson symptoms in younger patients.
Trihexyphenidyl
A patient with several episodes of vomiting and starts to have blood in the last episode with a NG suction showing bright red blood indicates this.
Mallory-Weiss (rupture of submucosal arteries in the distal esophagus and proximal stomach)
These interventions lower intracranial pressure
head elevation, sedation, IV mannitol (take free water from brain tissue thus osmotic diuresis), hyperventilation, removal of CSF
Pallor, weak pulses, and immediate spontaneous return of neuro function indicates this cause of LOC
syncope
Parkinsonism, autonomic dysfunction, and widespread neuro signs are signs of this.
Multiple System Atrophy (Shy-Drager)
Atrophy of caudate is associated with this.
Huntington’s
Atrophy of lenticular nucleus is associated with this.
Wilson’s
Atrophy of frontal and/or temporal lobes are associated with this.
Pick’s
This disease associated with increased intracranial pressure in an alert patient, no neuro signs except 6th nerve palsy, no intracranial HTN seen in imaging, and only increased CSF opening pressure is managed with this.
vision loss prevention and acetazolaminde (which inhibits choroid plexus carbonic anhydrase leading to decrease CSF production)
This is used to treat a patient who is inpatient and has severely elevated intracranial pressure
Mannitol
