1
Q

Increased pressure on the oculi motor nerve decreases parasympathetic stimulation. Sympathetic stimulation will predominate. Pupils will look like?

A

Dilated

2
Q

Bilateral Pupil dilation is an early or late sign of increases ICP?

A

Late

3
Q

Reflex, motor, and vision changes are contralateral, or ipsilateral, to the side of the injury?

A

Contralateral

4
Q

Eyes deviate Toward, or away from the side of the injury?

A

Toward

5
Q

What is the one neurological problem that causes pupil dilation BEFORE sustained change in level of consciousness?

A

Uncal herniation

6
Q

Protein is increased or decreased in the CSF of bacterial meningitis?

A

Increased

7
Q

What are the 2 major complications of subarachnoid hemorrhage?

A

Rebleed

Vasospasm

8
Q

What is the treatment for vasospasm ?

A

Aggressive fluid administration

9
Q

Seizures are an early or late sign of brain tumors?

A

Early

10
Q

What is always the 1st sign of a neuro Problem?

A

Change in level of consciousness

11
Q

Which is detected first?

Pronator drift? Or strength changes?

A

Pronator drift

12
Q

Vital sign changes are an Early, or Late sign of neurological injury?

A

Late (indicates that the brain stem is involved. )

13
Q

Uncal herniation occurs when…

A

The temporal lobe is displaced against the brainstem and 3rd cranial nerve (oculomotor).

14
Q

What is the most common cause of uncal herniation?

A

Epidural hematoma in the temporal area

15
Q

Central herniation is caused by….

A

Swelling on both sides, downward displacement of both hemispheres.

16
Q

Cerebral edema secondary to encephalopathy or stroke can cause….

A

Central herniation

17
Q

What should always be ruled out before treating an acute ischemic stroke?

A

Hypoglycemia (May mimic stroke symptoms)

18
Q

Patient has stroked and the BP is 219/119. Should you give antihypertensive??

A

No,do not treat unless SBP > 220 or DBP > 120. Suddenly decrease in BP will decrease perfusion to an area of the brain that has already lost perfusion, and may increase size of the ischemic area.

19
Q

Patient is here for MI but suddenly strokes. Should you give tpa?

A

No (MI in the past three months is contraindication for tpa.)

20
Q

Pt has stroke symptoms, CT of the head is negative

Should you give tpa?

A

Yes (CT head is an inclusion criteria for tpa administration)

21
Q

What is the goal BP for the first 24h after tpa administration?

A

SBP < 180

DBP < 105
