A 2-year-old presents with a history of limping, fever, and refusal to bear weight on an extremity. Which initial management step is most appropriate?

• A. Referral to ED
• B. Thorough physical examination
• C. Referral to orthopedics
• D. CBC with differential and ESR

Answer: (B)

The most important thing to do first is a thorough physical examination. In a toddler with fever, limp, and the unwillingness to bear weight, the exam is how you distinguish between serious joint or bone infection and more benign causes. A careful assessment should determine which joints are affected, the range of motion, presence of swelling or warmth, focal tenderness, and the child’s overall appearance and activity. This information helps you gauge the level of urgency—for example, a child who is febrile with focal joint findings and inability to bear weight raises strong concern for septic arthritis or osteomyelitis and requires urgent evaluation, while a more benign exam may lead to outpatient testing instead. Laboratory tests or specialist referrals are important downstream steps, but they depend on what you find during the physical examination. A CBC with differential and ESR can support the suspected diagnosis, and referrals to ED or orthopedics may be needed based on exam findings, but the exam is the foundation that guides those next actions.
