Final answer:
Elevated white blood cell count is an expected finding in osteomyelitis, while a normal C-reactive protein is an unexpected finding that should be reported to the provider.
Step-by-step explanation:
Osteomyelitis is an inflammation of bone tissues most commonly caused by infection. When assessing a client for osteomyelitis, an elevated white blood cell count is an expected finding, as it indicates the presence of infection. Therefore, the unexpected finding for osteomyelitis would be a normal C-reactive protein, as this marker is typically elevated in cases of infection.
