Answer to Question 1

B
National guidelines for the management of stroke are based on the results of the National Institute of Neurologic Disorders and Stroke rtPA Stroke Study. This study demonstrated that administration of recombinant tissue plasminogen activator within 3 hours of onset of the stroke was an effective and safe therapy for ischemic stroke. This time frame has now been expanded from 3 to 4.5 hours.

Control of eye movements occurs with interaction of three cranial nerves: oculomotor (III), trochlear (IV), and abducens (VI).
