Obtain a CBC for evaluation of neutropenia and other blood cell derangements. Assess electrolyte levels for signs of dehydration. The chest radiograph may show only subtle infiltrate. If diarrhea is present, perform urinalysis with a culture, blood cultures with samples from peripheral sites, cultures with samples from any indwelling catheters, and stool cultures for Clostridium difficile.

Administer broad-spectrum empiric antibiotics (eg, piperacillin, gentamicin, second- or third-generation cephalosporin) and an aminoglycoside. If the patient has a penicillin allergy, replace penicillin with carbapenem (if mild penicillin allergy) or aztreonam.

Treatment with granulocyte colony-stimulating factor (G-CSF) may be appropriate for raising neutrophil levels. Consultation with an oncologist is indicated to begin G-CSF therapy.
