Seth Jacobs is a 16-month-old boy who is brought to his pediatrician by his distraught mother on a Monday morning in early March. Mom describes a 2-day history of tugging at his right ear and crying, and a 2-day history of decreased appetite, decreased playfulness, and difficulty sleeping. Mom states that his temperature last night was elevated by electronic axial thermometer (39.5°C), so she gave him 5 mL of ibuprofen every 12 hours × 2 doses. When Seth is asked if anything hurts, he does not respond. Mom requests all recommendations be written as prescriptions (even ibuprofen) for day care administration. She also notes that it is tax season and she needs Seth to be able to return to day care immediately so she can return to work as an accountant.
