Show Hint
Bolus 30 mL/kg, then 70 mL/kg over 5 hours for a 6 kg infant.
Updated On: Jun 24, 2026
- RL infusion 120 ml in the first hour followed by 360 ml over the next 5 hours
- RL infusion 180 ml in the first hour followed by 420 ml over the next 5 hours
- RL infusion 180 ml in the first hour followed by 480 ml over the next 5 hours
- RL infusion 240 ml in the first hour followed by 360 ml over the next 5 hours
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Treat severe dehydration with rapid IV fluids using weight-based dosing for a 6 kg infant.
Step 2: The resuscitation bolus is 30 mL/kg, so the first-hour volume is \[30 \text{ mL/kg} \times 6 \text{ kg} = 180 \text{ mL}.\]
Step 3: The maintenance-replacement phase for a child under 12 months is 70 mL/kg over 5 hours, giving \[70 \text{ mL/kg} \times 6 \text{ kg} = 420 \text{ mL}.\]
Step 4: Adding these, the regimen is 180 mL in the first hour then 420 mL over the next 5 hours, which singles out the matching option.
\[\boxed{\text{180 ml in the first hour, then 420 ml over 5 hours}}\]
