SCRN EXAM 2025 (ALL 224 QUESTIONS WITH VERIFIED ANSWERS)
1. cerebral cortex: gray matter on the outermost section of the cerebrum and cerebellum
composed of neuronal cell bodies
2. Four lobes of the cerebral cortex and cerebrum: Frontal Parietal
Temporal Occipital
3. Oxygen supplemental need: > 93%
4. BP goal post tPA: <180/105
5. Vast majority of fatal hemorrhages occur within: the first 12 hours
6. hyperthermia management: strict < 38.0 or 100.4 tylenol for fevers
neurogenic fevers with an early increase in temperature
7. after 24 hours: can restart antihypertensives
8. blood pressure goals if they did not receive tPA: systolic < 220 diastolic < 120
** do not want to bring BP down fast d/t risk for hypotension
9. Co2 is a potent vasodilator: leads to an increase in ICP more blood volume to brain
mild hyperventilation for low CO2 leads to lower ICP and vasoconstriction Hypocarbia in extreme can lower
cerebral blood flow by too much
10. door to physician: < 10 min

13. Door to interpretation: < 45 min
14. door to tPA: < 60 min
15. BP if they did not receive TPA: 220/120
16. Acute care management: continue to monitor neurological status begin early mobilization of patient
close observation during transition sitting to standing
17. intracranial hemorrhage: hypertensive bleed venous thrombosis
trauma
18. subarachnoid hemorrhage: trauma aneurysmal
non-aneurysmal venous thrombosis
19. ischemic stroke: large vessel occlusions (LVO) usually from embolic sources
ICA MCA ACA PCA PICA AICA
Basilar
20. Small vessel occlusions: generally from atherosclerosis
21. vessels that feed cerebrum: MCA PCA
ACA
22. vessels that feeds the cerebellum: AICA PICA
SCA
23. vessels that feed the brainstem: basilar pontine
24. stroke mimics: seizures metabolic syndromes complex migraines

degenerative neurologic conditions CNS tumors
drug toxicity CNS abscess Bell's palsy
25. Neuroplasticity: the ability within the brain to constantly change both the struc- ture and function of
many cells in response to experience or trauma
adaptive or maladaptive rehab is key
26. SAH bp goal: < 140
27. ICH blood pressure goal: < 160
28. frontal lobe: motor, behavioral expression, motor and sensory maps
29. Parietal lobe: sensation, optic radiations carrying sensory input from the eyes, language centers
(typically left side of the brain) --> broca's and wernicke's
30. dysarthria: slurred speech reflecting poor motor control of the muscles associ- ated with speech and
language
31. occipital lobe: vision and interpretation of visual sensory signals
32. temporal lobe: coding visual memory and processing auditory and visual sen- sory input and
language comprehension
33. basal ganglia: coordinating center for several nerve tracts including coordinat- ing muscle movement
34. globus pallidus: component of the basal ganglia instrumental in control of voluntary muscle
movement
35. limbic system: group of nuclear and critical structures that encode memory and regulate autonomic
nervous system and endocrine function in response to emotional situations
