10

If CT is negative and you still believe there is a stroke what is the next best test to order?

Lumbar puncture

11

Migraine

Posterior

23

Under what conditions would aspirin or clopidogrel be used following a TIA as prophylaxis?

These are antiplatelet medications. They would be used unless there is a known cardiac etiology for the embolism. Patients with a cardiac cause should use heparin or coumadin.

24

A patient who is asymptomatic should consider having an endarterectomy at what percent blockage of the carotid artery? How about in a symptomatic patient?

70% in an asymptomatic patient and greater than 60% in a symptomatic patient.

25

A patient presents complaining of the worst headache of his life. What might you expect their blood pressure to be?

Typically this is the description for a subarachnoid hemorrhage. You would expect the blood pressure to be elevated.

26

Name one abortive drug for migraines.

Triptans (sumatriptan, zolmitriptan), Ergotamine

27

An EEG showing focal rhythmic discharges at the onset of the seizure should make you think of what diagnosis?

Simple partial seizure

28

What is the single most important thing to be concerned about with a patient in status epilepticus?

Airway, followed by management of hyperthermia.

29

Describe Brudzinski's sign.

When you lift the patient's head the patient bends his hips.

30

Name three medications used to break a seizure?

Diazepam, lorazepam, phenytoin or fosphenytoin.

31
