Final answer:
A diagnosis of bacterial meningitis is suggested by the CSF results, which show abnormal levels of polymorphonuclear neutrophils and low glucose. Bacterial meningitis is a serious infection of the meninges.
Step-by-step explanation:
A diagnosis of bacterial meningitis is suggested by the following CSF results: opening pressure of 190 mm Hg, protein level of 110 mg/dL, glucose level of 27 mg/dL, and a leukocyte count of 5,000/mm³. These values indicate abnormal levels of polymorphonuclear neutrophils and low glucose, which are characteristic of bacterial meningitis. Bacterial meningitis is a serious infection of the meninges, the protective membranes covering the brain and spinal cord.
