While working your shift in a small community ED, you overhear that EMS is on their way to you with a five-year-old child in respiratory distress after eating a peanut butter sandwich. Anticipating the patient to be in anaphylactic shock, you and the senior resident begin planning the course of action. The resident asks, “how much do you think a five-year-old weighs?” While you begin fumbling for your Broselow tape, a nurse seated near you confidently responds, “That’s easy, just count your fingers! One, three, five. Ten, fifteen, twenty! The child weighs approximately twenty kilograms!”.
