C. BP 200/60, HR 50, RR 8
- The patient has a blood pressure of 130/88 and ICP reading of 12. What is the patient’s cerebral pension pressure, and now do you interpret this as the nurse?
A. 90 mmHg, normal
B. 62 mmHg, abnormal
C. 36 mmHg, abnormal

During the eye assessment of a patient with increased ICP, you need to assess tha oculocephalic reflex. If the patient has brain stem damage what response will you find?

C. The eves will roll back as the head is moved side to side.
D. The eyes will be in a fixed midline position as the head is moved side to side.
D. The eyes will be in a fixed midline position as the head is moved side to side.
positive response occurs when the eyes rotate to the opposite side to the direction of head rotation, thus indicating that the brainstem (CN3,6,8) is intact.
