6. When will you start antihypertensive treatment in a patient with a stroke due to bleeding into the brain?
Options are:

D. When the BP is more than 160mm Hg systolic

7. Thrombolytic therapy with Alteplase (recombinant tissue type plasminogen activator) is recommended for ischemic strokes within 4.5 hours of onset. In which of the following situations will you prefer NOT to use rtPA? More than one answer is acceptable.

Options are: A. On the first day. B. On the fifth day. C. On the fourteenth day.

9. When patients who are on warfarin develop a cerebral hemorrhage, we give them Vitamin K and fresh frozen plasma to reduce the volume of bleeding. What can we give to reduce the volume of bleeding in patients with cerebral hemorrhage who are not on warfarin?
Options are:
A. Activated Factor VII
B. Activated Factor VIII
C. Activated Factor X
