Reference no: EM133482791

It is early December. Mark, a 7-year-old boy, is in your office this morning with his father after a very restless night; mom is out of town. Dad states that his son was sent home from school 3 days ago after vomiting. Mark awoke the next morning with a fever of 102°F, body aches, a cough, a sore throat, and a runny nose. After 2 days of taking over-the-counter children's cold medicine, he still had a fever. In your office this morning, you note he is febrile, pale, and shaky; his skin is clammy and sweaty. There are no sick contacts in his home. Dad is not sure if the children have received flu vaccinations this season and your EMR has no flu vaccine documentation (but the immunization could have been received elsewhere). List five differential diagnoses that you feel are likely to explain this patient's presentation List your most likely diagnosis first ("working diagnosis"), followed by 4 other reasonable alternatives. Using the grid below each diagnosis, enter the inclusion or exclusion rationale from the history and the physical examination that support each one.
