Final answer:
The daily maintenance fluid requirement for a 5 kg infant is 500 mL per day, following the standard formula of 100 mL/kg for the first 10 kg of body weight.
Step-by-step explanation:
Daily Maintenance Fluid Requirement for a 5 kg Infant
The daily maintenance fluid requirement for a 5 kg infant is based on a widely accepted pediatric formula: 100 mL/kg for the first 10 kg of body weight. Therefore, for a 5 kg infant, the fluid requirement would be calculated as follows:
- 5 kg × 100 mL/kg = 500 mL per day
This is the amount of fluid needed to maintain normal hydration in a typically healthy infant without additional fluid losses. It is important to note that in clinical practice, individual patient needs may vary due to factors such as fever, vomiting, diarrhea, or underlying medical conditions, and assessments should be made by healthcare professionals.
