Option by option

Measure visual acuity does not correspond to the stated orthopedic infection finding.
B. Assess pulmonary function
Assess pulmonary function may apply to a different condition but is not the best response here.
C. Differentiate septic and crystal arthritis (correct)
Correct. Differentiate septic and crystal arthritis directly addresses the essential clue in this sample.
D. Treat all fractures
Treat all fractures is not supported by the clinical description or management aim.
