Flashcards in FINAL EXAM MO (Felicia) Deck (229)
EMG to the lateral rectus monitors what nerves?
*On a diagram, what area of the brain would be supplied by the anterior cerebral artery?
outer layer of the brain, Left/Top side. (blue on exam)
(anterior meaning top)
*On a diagram, what area of the brain is supplied by the posterior cerebral artery?
outer lower right side of the brain. (green on exam)
(posterior- lower area)
BP = 100/70
HR = 65
RAP = 10
ICP = 15
CPP = MAP - ICP
MAP is [(diastolic x 2 )plus systolic] / 3.
Thus 80-15 = 65 = CPP
SSEP assesses the integrity of what part of the spinal cord?
posterior spinal cord
Name structures pierced during lumbar puncture? (short answer)
Patient with increased ICP that suddenly rises to 30 mmHg will exhibit? SELECT 3
Which potential is MOST RESISTANT to anesthesia?
* Where is the subarachnoid space on diagram?
look at a diagram for this one until an image is added lol
Which nerve can be blocked to decrease pain from tourniquet inflation during IV regional anesthesia?
Aqueduct of sylvius supplies?
third and fourth ventricle
*Cerebral blood flow and partial pressure graph, know what each line represents.
x = PaCO2 (line that starts low and ends at the top)
y = PaO2 (line that starts high and levels out in the middle)
*Tell me where on the hand (posterior and anterior) which nerves innervate what parts of the hand.
ulnar is pinky and half of ring finger of hand on both sides (blue)
Radial is typically green on diagram and median is yellow lol
Which evoked potential is measured during pituitary surgery
Visual evoked potential
What part of the brain controls the activity of interneurons in the substantia gelatinosa?
Periventricular and periaqueductal gray matter
Gray Ramus contains what kind of fibers?

Oculomotor the third cranial nerve
Name a drug combination that decreases cerebral blood flow?
A 55-year-old is undergoing an intracranial tumor resection under GA. Preoperatively, the patient is alert & oriented and has no focal neurological deficit. Within what range should the PaCO2 be maintained during surgery?
Which bone supports the pituitary gland
Ketamine, tell me if it has any change on CMR, CBF, CSF production, CSF re-absorption, CBV, or ICP?
has little or no change to CMR or CSF production.
Increases CBF, CBV, ICP.
Decreases only CSF re-absorption.
If someone has head trauma and you are choosing an agent to treat them with, what would you want said agent to possess?
be able to decrease CMR, CBF, CBV, ICP
and increased re-absorbtion of CSF
Masseter muscle and temporalis muscle responses are monitored using which nerve?
Trigeminal CN V

3 cm above
In the case of venous air embolism, aspiration with a multi-orificed catheter is done by placing the tip ________ the SVC-atrial junction.
2 cm below
If a man is smiling and half of his face only is smiling then what nerve is injured?
Pain, afferent nerve fibers, dorsal horn ascend 1-3 seg ____ in before entering synapse dorsal horn?
Track of lissauer
