Final Exam| Questions and Answers|
Graded A
Stimulation assessment should be made on patients monitored in the ICU Daily
What is the primary goal of conducting stimulation assessments for patients in the ICU?
To monitor brain function and identify abnormal neurological responses.
How frequently should stimulation assessments be performed on ICU patients?
Daily, to track changes in neurological status and response to treatment.
Where is the central sulcus located in relation to the primary motor cortex?
Between the precentral gyrus (motor cortex) and the postcentral gyrus (sensory cortex).
How does temporal lobectomy in the dominant hemisphere impact language functions?
It may impair speech and language comprehension due to the involvement of the language-
dominant side of the brain.
What EEG findings would most likely be seen in a 58-year-old survivor of cardiopulmonary
resuscitation (CPR)?
Diffuse slow wave activity, reflecting hypoxic brain injury and post-resuscitation changes.
1
,What is the purpose of using bilateral mesial temporal depth electrodes in epilepsy monitoring?
To localize the seizure focus, particularly in the hippocampus, and determine the side of
seizure origin.
Why are bilateral mesial temporal electrodes preferred for patients with epilepsy?
They provide more accurate localization of seizure foci, which is critical for surgical
planning.
What is the primary function least likely affected by a temporal lobectomy in the dominant
hemisphere?
Supplementary motor deficits, as this region primarily affects motor coordination.
What should be done if patient information needs to be released without written consent?
It should be reviewed by legal or ethical committees to determine if it is permissible under
exceptions such as emergencies or legal requirements.
How can EEG help in monitoring the recovery of a patient after cardiac arrest?
EEG can assess the depth of coma and predict long-term neurological outcomes by
identifying brain activity patterns.
What does the ACNS recommend for low-frequency and high-frequency filter settings in EEG?
Low-frequency filter (LFF) at 0.5 Hz and high-frequency filter (HFF) at 70 Hz for optimal
signal clarity.
2
, Why are filter settings important in EEG monitoring?
To reduce artifact interference and ensure accurate recording of brain activity.
What role does the central sulcus play in motor and sensory functions?
It separates the areas responsible for voluntary motor control and sensory processing.
Under what circumstances can patient information be legally released to a third party?
Only with written consent from the patient, ensuring confidentiality is maintained according
to privacy laws.
What is the primary goal of temporal lobectomy in the dominant hemisphere?
To remove epileptic foci while minimizing functional impairments, especially in memory
and speech areas.
What is the significance of lateralizing the seizure focus in patients undergoing epilepsy surgery?
It helps guide the surgical approach and improve outcomes by targeting the correct brain
region.
What impact does bilateral mesial temporal depth electrodes have on seizure localization?
They provide precise localization for the determination of the side of the brain responsible
for the seizures.
