You have just started working in an Urgent Care Clinic as a nurse. Mom brings in her 3 year old little boy, Brandon. Mom states that Brandon has been having fever up to 104F and he isn't eating or drinking anything because he feels very sick to his stomach, not to mention crabby! He's also been pulling a lot at his right ear and sounds congested. At the last well visit with the Pediatrician (about 2 weeks ago), Mom states that Brandon weighed 32 pounds. On exam today, his weight is 12.5 kg. Additionally his eyes are darkened and sunken, his mouth is dry with some white crusting around the lips. His temperature is 39C, other vitals signs are normal. Though he looks ill he appears to be medically stable. The doctor rushes in, quickly exams Brandon, diagnoses him with otitis media and then barks off orders to you that you then need to convey accurately to Mom. The orders include: push fluids, ibuprofen 10mg/kg every 6 hours if temp > 38C, and begin taking a 10-day course of…
