5. A patient has several seemingly unrelated abnormalities involving joints, kidneys, skin, and blood counts. Which diagnostic strategy is most appropriate?

   • A. Reassess the complete symptom timeline and associated findings
   • B. Ignore the laboratory abnormalities
   • C. Search for a unifying systemic disorder
