Final answer:
The classic findings on a complete blood count (CBC) for a patient with eczema herpeticum include an elevated white blood cell count, specifically the neutrophil count, and a high eosinophil count. Abnormalities in liver function tests may also be observed if the infection has spread to the liver.
Step-by-step explanation:
Eczema herpeticum is a serious complication of eczema that can be life-threatening. It occurs when eczema is infected with the herpes simplex virus (HSV). In this case, for a patient with eczema herpeticum, a classic of the complete blood count (CBC) may show an elevated white blood cell count, specifically the neutrophil count, which is indicative of an infection. The CBC may also show a high eosinophil count, which is commonly seen in patients with eczema. Additionally, the patient's liver function tests may show abnormalities if the infection has spread to the liver.
