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
