A child is being treated for dehydration with intravenous fluids. The child currently weighs 13 kg and is estimated to have lost 7% of his normal body weight. The nurse is double-checking the IV rate the healthcare provider prescribed

Question

The formula the healthcare provider used was for maintenance fluids: 1000 mL for 10 kg of body weight plus 50 mL for every kilogram over 10 for 24 hours. Replacement fluid is the percentage of lost body weight × 10 per kg of body weight. According to the calculation for maintenance plus replacement fluid, which hourly IV rate will the nurse implement for 24 hours? 1. 88 mL/hr
2. 86 mL/hr
3. 81 mL/hr
4. 83 mL/hr

Explanation:
1. Maintenance need for 13 kg is 1000 + (50 [×] 3), or 1150 mL/24 hours. Add to this the replacement fluid loss = 7 (% of total body weight lost) × 10 = 70 mL/kg/24 hours (70 × 13 = 910). 1,150 + 910 = 2060 for 24 hours. 2060/24 = 86 mL per hour.
2. Maintenance need for 13 kg is 1000 + (50 [×] 3), or 1150 mL/24 hours. Add to this the replacement fluid loss = 7 (% of total body weight lost) × 10 = 70 mL/kg/24 hours (70 × 13 = 910). 1150 + 910 = 2060 for 24 hours. 2060/24 = 86 mL per hour.
3. Maintenance need for 13 kg is 1000 + (50 [×] 3), or 1150 mL/24 hours. Add to this the replacement fluid loss = 7 (% of total body weight lost) × 10 = 70 mL/kg/24 hours (70 × 13 = 910). 1150 + 910 = 2060 for 24 hours. 2060/24 = 86 mL per hour.
4. Maintenance need for 13 kg is 1000 + (50 [×] 3), or 1150 mL/24 hours. Add to this the replacement fluid loss = 7 (% of total body weight lost) × 10 = 70 mL/kg/24 hours (70 × 13 = 910). 1150 + 910 = 2060 for 24 hours. 2060/24 = 86 mL per hour.
