A patient at risk for increased intracranial pressure (ICP) is likely to experience involuntary compensatory mechanisms

The nurse would monitor this patient for signs of which involuntary compensation? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply. 1. Vasoconstriction of cardiac vessels
2. Vasodilation of the cerebral vessels
3. Decreased production of cerebral spinal fluid (CSF)
4. Decreased metabolic energy needs
5. Increased absorption of cerebral spinal fluid (CSF)


3,4,5
Rationale 1: Vasoconstriction of cardiac vessels is not a normal compensatory mechanism for ICP.
Rationale 2: Vasoconstriction of the cerebral blood vessels results as space becomes compressed.
Rationale 3: For the brain to maintain a normal ICP, attempts are made to compensate for changes in any of the three components within the brain. Initial mechanisms for ICP may include changing the volume of CSF by decreasing production.
Rationale 4: Autoregulation can help maintain adequate tissue perfusion by adjusting metabolic needs.
Rationale 5: For the brain to maintain a normal ICP, attempts are made to compensate for changes in any of the three components within the brain. Initial mechanisms for ICP may include changing the volume of CSF by increasing absorption.
