Yоu аre аn emergency rооm physiciаn. Marcus, a 7-year-old boy, has just presented in the ER complaining that his chest hurts, his heart feels funny, and his ankles and knees hurt. His mother says that he has had a fever for the past 24 hours. Upon physical examination, you notice that his ankles and knees are red and swollen, and examination with a stethoscope reveals unusual palpitations (his heart is fluttering). You immediately order an EKG to check for signs of a heart-attack, a CBC blood draw to check for signs of infection, a throat culture to check for presence of Streptococcus, an X-ray of his legs to check for bone fractures or lesions, and a urine sample to check for bacterial contamination.You decide to go ahead and treat him with a broad-scale antibiotic, right there in the emergency room to get things started. You decide this prior to getting back any test results. Which hypothesis might you be testing?
