Who you are: You are FY2 in the medicine department.

Who the patient is: A 60-year-old man presented with cough. He had a CXR and was diagnosed with pneumonia 4 weeks ago. Based on his CXR, he was discharged on antibiotics. On looking at his X-ray, we found that he was treated based on another patient's x-ray. Your consultant thinks that the patient was given antibiotics unnecessarily for 4 weeks. Today, he is coming for a follow up.

What you should do: Talk to the patient, explain the medical error and discuss the management with him.
