2. The patient could be developing sepsis.
3. The patient is healing.
4. The patient has lymphoma in addition to a leg wound.

Rationale 1: If the wound were caused by a parasite, the eosinophils would be elevated.

Rationale 3: Elevated bands do not indicate that the patient is healing.
Rationale 4: Lymphocytes are elevated in a patient diagnosed with lymphoma in addition to an infection.
