A 64 year old woman is brought to the ER in a confused state. She is found to have a temperature of 39.5 degrees C and pronounced nuchal rigidity. A lumbar puncture, with the patient in lateral decubitus position, reveals an opening pressure of 270 mm H2O. Four tubes of CSF, each containing 3 ml of liquid are collected. CSF findings include: Tube #1: WBCs = 300 (mostly PMNs), RBCs = 2800, protein = 180 mg/dl, glucose = 10 mg/dl. Tube #4: WBCs = 320 (mostly PMNS), RBCs = 700, protein = 176 mg/dl, glucose = 10 mg/dl. These findings are consistent with:

a normal lumbar puncture and viral meningitis

a traumatic lumbar puncture and viral meningitis

a normal lumbar puncture and bacterial meningitis

a traumatic lumbar puncture and bacterial meningitis
