A patient’s cerebrospinal fluid (CSF) is noted to have a protein level of 52 mg/dL and a glucose level of 28 mg/dL (serum glucose level 82 mg/dL). Additionally, there is an abundance (>1,000 cells/mL) of polymorphonucleocytes (PMNs) present but no erythrocytes. How does the nurse interpret these results?

The 68-year-old patient is admitted after 5 days of extremely foul-smelling watery diarrhea with a temperature of 37.9°C, heart rate 118 bpm, and blood pressure 98/52 mmHg. The patient’s recent medical history is significant for being treated 2 weeks ago for a diverticulitis flare-up. Upon assessment, the patient is pale, diaphoretic, and has a tense, distended abdomen that he does not guard with palpation. Lab studies reveal an elevated creatinine (1.9 mg/dL), high white blood cell count (20,000 cells/mL), and normal hemoglobin and hematocrit. The nurse prepares to perform which diagnostic test for this patient?
