A client at risk for increased intracranial pressure (ICP) is likely to experience involuntary compensatory mechanisms. The nurse recognizes that these alterations may include: Select all that apply
1. Increased absorption of cerebral spinal fluid (CSF).
2. Decreased production of cerebral spinal fluid (CSF).
3. Decreased metabolic energy needs.
4. Vasodilation of the cerebral vessels.
5. Vasoconstriction of cardiac vessels.
1. Increased absorption of cerebral spinal fluid (CSF).
2. Decreased production of cerebral spinal fluid (CSF).
3. Decreased metabolic energy needs.
Rationale: Increased absorption of cerebral spinal fluid (CSF). In order 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. Decreased production of cerebral spinal fluid (CSF). In order 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. Decreased metabolic energy needs. A decrease in metabolic energy needs is likely. Vasodilation of the cerebral vessels. Vasoconstriction of the cerebral blood vessels will result as space becomes compressed. Vasoconstriction of cardiac vessels. Vasoconstriction of cardiac vessels is not a normal compensatory mechanism seen for ICP.
