Question 1

Stroke like symptoms & seizure suggest:

Answer 1

Question 2

Normal CPP minimum to perfuse brain? What % CO goes to brain?

Answer 2

Question 3

Basilar skull fracture: facial symptoms & cranial nerve involvement

Answer 3

Facial palsy, nystagmus, facial numbness

Cranial nerves: V, VI, VII

Question 4

When calculating the CPP, you don’t know the ICP… What should you use?

Answer 4

Upper range of ICP normal, 0-15

Electrical Alterans

Answer 7

• caused by pericardiac tamponade of effusion
• due to fluids in sac
• alteration of QRS amplitude, or axis between beats, possible wandering baseline.
