A client has a history of normal pressure hydrocephaly. What physiological function most likely occurs to maintain this client's intracranial pressure within normal limits? Select all that apply
1. Displacing of brain tissue
2. Administer osmotic diuretics
3. Reducing the amount of cerebral oxygen
4. Compressing the cerebral venous system
5. Shunting of cerebrospinal fluid to the lumbar space
1, 4. 5
Rationale 1: The brain can control increased intracranial pressure by displacing brain tissue.
Rationale 2: Administering osmotic diuretics is a pharmacological intervention to control increased intracranial pressure.
Rationale 3: Reducing the amount of cerebral oxygen will harm brain tissue.
Rationale 4: The brain can control increased intracranial pressure by compression of the cerebral venous system to reduce cerebral blood volume.
Rationale 5: The brain can control increased intracranial pressure by shunting CSF from the intracranial to the lumbar space, where CSF reabsorption is increased.
Global Rationale: The brain can control increased intracranial pressure by displacing brain tissue, compressing the cerebral venous system to reduce cerebral blood volume, and shunting CSF from the intracranial to the lumbar space, where CSF reabsorption is increased. Administering osmotic diuretics is a pharmacological intervention to control increased intracranial pressure. Reducing the amount of cerebral oxygen will harm brain tissue.
