Q: What is the zinc supplementation dose for children older than 6 months?

For children ≥6 months old, zinc supplementation is 20 mg/day for 10-14 days. For children <6 months, the dose is 10 mg/day for 10-14 days.

Q: Which of the following is NOT listed as a reason why children are at higher risk for dehydration?

Children have IMMATURE renal concentrating ability, which puts them at higher risk for dehydration. The other options are all correctly listed as risk factors.

Q: What is the ORS volume recommendation for Plan B treatment?

Plan B for some dehydration recommends ORS 75 ml/kg over 4 hours, given as small frequent sips or via nasogastric tube if needed.

Dehydration in pediatrics refers to a reduction in total body water with or without electrolyte imbalance, and children are particularly vulnerable due to their higher body water percentage, increased surface area-to-volume ratio, immature renal concentrating ability, and dependence on caregivers for fluid intake. Clinical assessment relies on recognizing progressive signs ranging from thirst and reduced urine output to sunken eyes, poor skin turgor, and in severe cases, altered mental status, weak pulses, and shock. Understanding the WHO classification system of no, some, and severe dehydration is essential for medical students as it directly guides management from oral rehydration therapy at home to intravenous fluid resuscitation, making accurate assessment a critical skill in pediatric emergency care.
