Answer: D · ReSoMal 5 ml/kg every 30 minutes for 2 hours
Children with SAM are rehydrated orally or by NG tube, slowly, with ReSoMal: 5 ml/kg every 30 minutes for 2 hours, then 5-10 ml/kg/hour for up to 10 hours, watching for overload. Signs of dehydration are hard to judge in SAM, and their weak hearts tolerate fast fluids poorly. IV fluids are kept for shock.
- A: Standard ORS has too much sodium and too little potassium for SAM.
- B: Rapid IV fluids can cause heart failure in SAM and are only for shock.
- C: Plain water does not replace electrolytes.
Remember this
Dehydration in SAM without shock: oral ReSoMal 5 ml/kg every 30 minutes for 2 hours, then 5-10 ml/kg/hour.
