Explanation
A. Increased ICP would be a concern when the MAP falls below 70 mm Hg because reduced blood pressure can lead to inadequate cerebral blood flow and worsen ICP.
B. Decreased cerebral blood flow (CBF) is also a concern with low MAP, but the priority is maintaining MAP at a sufficient level to ensure adequate perfusion.
C. Increased CPP is unlikely with a low MAP, as CPP is a product of MAP and ICP.
D. Normal ICP would be a good outcome; however, with a low MAP, the nurse should be concerned about insufficient cerebral perfusion and the risk of increased ICP.
