Answer to Question 1

D
An unruptured aneurysm may be problematic because it places pressure on the surrounding tissues. The aneurysm becomes clinically significant when the vessel wall becomes so thin that it ruptures, sending arterial blood at a high pressure into the subarachnoid space.

Answer to Question 2

B
To assess the oculocephalic reflex, the nurse holds the patient's eyelids open and briskly turns the head to one side while observing the eye movements and then briskly turns the head to the other side and observes. If the eyes deviate to the opposite direction in which the head is turned, doll's eyes are present, and the oculocephalic reflex arc is intact. If the oculocephalic reflex arc is not intact, the reflex is absent.
