Question: Which statement most accurately reflects the ischemic penumbra (IP)? options: IP is an area of neuronal death that results from a reduction in cerebral blood flow. Autoregulatory mechanisms required to regulate blood pressure and pulse are preserved in the IP. Cerebral blood flow in the IP is at a higher pressure than blood flow to the rest of the brain. IP is a potentially salvageable area with marginal blood flow that surrounds a core of ischemic brain tissue.
