craniotabes
Skull ossification continues through what?
puberty until mid-20s
Pressure of CSF in the subarachnoid space between the skull and the brain
ICP
Complications of increased intracranial pressure?
decreasing cerebral perfusion leads to ischemia and anoxia

Kernig’s or Brudzinski’s Sign
Diagnosis of Meningitis
CSF, Assume positive in infants <2 months old until cultures come back negative
Nursing Inverventions for Meningitis:
Monitor ICP; neuro checks q2; isolate children, hydrate, decrease stimuli, prevent future episodes, comfort care
How to prevent future episodes of Meningitis:
Teach family about complete and early treatment of URI; Hib vaccine in children under 5
