Head case
This part of the brain is responsible for higher cognitive function, voluntary motor function and expressive language.
What is the function of the frontal lobe of the brain?
The supraorbital technique and the nail bed technique.
What are methods for eliciting a painful response?
The involuntary, rhythmic movement of the eyes.
What is nystagmus?
Decreased pulse, decreased or irregular respirations, and increased BP.
What is Cushing reflex?
Pre-death breathing pattern characterized by gradual increases and decreases in respirations with periods of apnea.
What are Cheyne-stokes respirations?
This part of the brain is responsible for processing and perceiving visual information.
What is the function of the occipital lobe?
The finding of unequal pupils.
What is anisocoria?
When a patient is asked to hold both arms extended in front of them, with eyes closed, and one arm drifts downward and turns toward the body (pronates).
What is a positive pronator drift?
Hyperventilation and subsequent decreased CO2 causes this problem.
What is cerebral vasoconstriction?
3 to 4.5 hours from the onset of symptom onset.
What is the time to administer fibrinolytics in ischemic stroke?
The part of the brain responsible for gross and fine motor and coordination.
What is the cerebellum?
Abnormal flexion; a patient flexes their arms and curls them inward towards the chest while pointing their toes.
What is decorticate posturing?
Shaking that occurs when a patient is asked to reach and grab something.
What is an intention tremor?
Hypoventilation and subsequent high CO2 causes this problem.
What is vasodilation?
Respiratory pattern associated with brain stem injury that is characterized by irregular respirations with period of apnea.
What are biot/ataxic respirations?
Nerves that do not cross mid-line and therefore produce symptoms on the same side of the body as the stroke or injury in the brain.
What are the cranial nerves?
Abnormal extension; a patient points their toes while extending arms and pronating the palms.
What is decerebrate posturing?
A sensation of numbness and tingling.
What is paresthesia?
Increased ICP causing intracranial contents to be displaced within the cranial vault or through the foramen magnum causing eventual loss of autonomic functions.
What is herniation?
A patient with suspected meningitis involuntarily flexes her knees when her head is flexed toward her chest.
What is a positive Brudzinski sign?
This part of the brain filters unnecessary information before it reaches the cerebral cortex and is composed of the thalamus and hypothalamus.
What is the diencephalon?
A protective reflex that closes the eyes, pulls the head posteriorly, and constricts the pupils.
What is the corneal reflex?
A rigid, contracted body posture; arms, legs, neck, and back contract so tightly that the body part shakes.
What is tonic activity?
ETCO2 goal for patients suffering ICP with signs of brain stem herniation.
What is ETCO2 of 30-35 mm Hg
The correct position for patients with increased ICP.
What is having the head elevated at 30 degrees?
