1

EMG to the lateral rectus monitors what nerves?

Abducens (6)

2

*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)

3

*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)

4

Calculate CPP:
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

5

SSEP assesses the integrity of what part of the spinal cord?

posterior spinal cord

6

Name structures pierced during lumbar puncture? (short answer)

Skin
subcutaneous tissue
supraspinous ligament
interspinous ligament
ligamentum flavum
epidural space
dura mater
subdural space*
arachnoid mater
subarachnoid space

7

Patient with increased ICP that suddenly rises to 30 mmHg will exhibit? SELECT 3

Irregular respiration
bradycardia
hypertension

8

Which potential is MOST RESISTANT to anesthesia?

BAEP- Auditory

9

* Where is the subarachnoid space on diagram?

look at a diagram for this one until an image is added lol

10

Which nerve can be blocked to decrease pain from tourniquet inflation during IV regional anesthesia?

Intercostalbrachial nerve

11

Aqueduct of sylvius supplies?

third and fourth ventricle

12

*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)

13

*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

14

Which evoked potential is measured during pituitary surgery

Visual evoked potential

15

What part of the brain controls the activity of interneurons in the substantia gelatinosa?

Periventricular and periaqueductal gray matter

16

Gray Ramus contains what kind of fibers?

Postganglionic sympathetic fibers

17

Patient has eyelid drooping, pupil fixed and dilated, not reactive to light. What nerve is damaged?

Oculomotor the third cranial nerve

18

Name a drug combination that decreases cerebral blood flow?

Fentanyl- droperidol

19

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?

25-30

20

Which bone supports the pituitary gland

Sphenoid bone

21

Ketamine, tell me if it has any change on CMR, CBF, CSF production, CSF re-absorption, CBV, or ICP?

Ketamine:

has little or no change to CMR or CSF production.

Increases CBF, CBV, ICP.

Decreases only CSF re-absorption.

22

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

23

Masseter muscle and temporalis muscle responses are monitored using which nerve?

Trigeminal CN V

24

In the case of venous air embolism, aspiration with a single-orificed catheter is done by placing the tip ________ the SVC-atrial junction.

3 cm above

25

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

26

If a man is smiling and half of his face only is smiling then what nerve is injured?

Facial VII

27

Pain, afferent nerve fibers, dorsal horn ascend 1-3 seg ____ in before entering synapse dorsal horn?

Track of lissauer

28

Berry aneurysm picture, damage is where?

Anterior communicating artery

29

Picture of drop hand (wrist drop) what nerve is damaged?

radial nerve damage

30

Describe a baby with Erb-Duchenne palsy?

Excessive stretch of neck during delivery, damage to superior trunk of C5, C6. Can occur in falls, traumas. Pronated forearm, arm turned medially
