Burns — Wallace Rule of Nines + Parkland Formula

A 3-year-old child presents to the emergency department with a 20% TBSA scald burn involving the head, neck, and upper trunk. The structure marked **A** in the Wallace Rule of Nines diagram accounts for a significantly larger proportion of body surface area in children compared to adults. Using the Parkland Formula, what is the total volume of lactated Ringer's solution required for the first 24 hours of resuscitation in this 15 kg child? (Assume the burn occurred 1 hour ago and only partial-thickness burns are included in the calculation.)
