A patient with a head injury has a mean arterial pressure of 70 mm Hg and an intracranial pressure of 20 mm Hg.Which cerebral perfusion pressure would the nurse document for this patient?
A)50 mm Hg
B)90 mm Hg
C)70/40 mm Hg
D)40/70 mm Hg

The cerebral perfusion pressure (CPP) can be calculated by subtracting the intracranial pressure (ICP) from the mean arterial pressure (MAP).

CPP = MAP - ICP

Using the given values: 
CPP = 70 mm Hg - 20 mm Hg = 50 mm Hg

Therefore, the nurse would document a cerebral perfusion pressure of 50 mm Hg for this patient.
