A calculation is not the whole fluid plan
A fictional 14 kg child is being assessed after a minor procedure. For an arithmetic exercise only, the supplied maintenance model assigns 100 mL per kilogram for the first 10 kg and 50 mL per kilogram for the next 10 kg over one day. A trainee calculates a volume and writes it as an automatic prescription without reviewing the child. The actual chart has not yet supplied renal function, electrolytes, oral intake, ongoing losses or the physiological response to illness. The supervising clinician asks the trainee to show the calculation separately from selecting an individual fluid composition and rate. The case deliberately supplies a model rather than a universal instruction for every postoperative child.
1. Calculate the model volume.

The first 10 kg contributes 1000 mL and the remaining 4 kg contributes 200 mL, totaling 1200 mL in the supplied daily model.
2. Why is that not a complete prescription?
Read the worked answer
Actual fluid need, composition and rate depend on the clinical assessment, intake, losses, renal and electrolyte findings and ongoing response.
