1. What are the factors that affect cerebral blood vessel tone? Ex: CO2, temperature,
shivering, what makes it go up vs down?
2. Reticular activating system responsible for wakefulness, ability to focus, fight or flight

3. Know Cushing’s triad, what is it and what are the three components?
4. What is the Monroe-Kellie doctrine?

7. What is the drug therapy for managing increased ICP?
8. Raccoon sign vs Battle’s sign
9. For A-line, know that you have to zero the system and align the transducer at the
phlebostatic axis
10. Know about the stages of shock. Compensatory, progressive, refractory, what will we see
in each?
11. Know how to use the Parkland formula and calculate based on a scenario. Here is a
practice problem:
