Correct answer: E — Collect blood cultures, obtain MRI and begin empiric antibiotics

Explanation lettering: D = shown as A · E = shown as D · A = shown as E

A is correct. Early acute osteomyelitis can have normal radiographs; cultures, MRI or other timely imaging, specialist input and prompt empiric therapy are required. B relies on an insensitive early test. C suppresses immunity before infection is excluded. D confuses bone and joint pathways. E waits for late complicated disease and a poor specimen.
