Calculate the total intravenous fluids infused in 24 hrs for a 147.4-lb client with a 31.5% TBSA burn and receiving insulin 5 units/hr. The concentration of insulin is 100 units in 100 mL normal saline.
8750mL
8000mL
8562mL
8502 mL
The Correct Answer is C
To calculate the total intravenous fluids infused in 24 hours for a burn client, use the Parkland formula.
- Calculate Fluid Resuscitation Volume (Parkland Formula)
Convert client's weight from pounds (lb) to kilograms (kg).
Client weight = 147.4 lb / 2.2 lb/kg
= 67 kg.
- Calculate the total fluid volume needed for the first 24 hours using the Parkland formula.
Parkland Formula = 4 mL × client weight (kg) × % TBSA burned
Total fluid volume (24 hrs) = 4 mL × 67 kg × 31.5%
= 8442 mL.
- Calculate Insulin Infusion Volume in 24 hours
Concentration of the insulin solution = 100 units / 100 mL
= 1 unit/mL.
- Calculate the volume of insulin solution infused per hour.
Infusion rate = 5 units/hr
Volume infused per hour (mL/hr) = Desired units/hr / Concentration (units/mL)
= 5 units/hr / 1 unit/mL
= 5 mL/hr.
- Calculate the total volume of insulin solution infused in 24 hours.
Total insulin volume (24 hrs) = Volume infused per hour (mL/hr) × 24 hours
= 5 mL/hr × 24 hours
= 120 mL.
- Calculate Total Intravenous Fluids Infused in 24 hours
Total IV fluids = Total fluid resuscitation volume + Total insulin volume
= 8442 mL + 120 mL Total IV fluids
= 8562 mL.

Correct Answer is ["125"]
Explanation
Total volume to be infused = 250 mL.
Infusion time = 2 hr.
- Calculate the infusion rate in milliliters per hour (mL/hr).
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
= 250 mL / 2 hr
= 125 mL/hr.
Correct Answer is ["31.5"]
Explanation
- Calculation of the TBSA according to the rule of 9s:
Anterior Trunk: 18%
Right Arm: 9% (full arm on both posterior and anterior aspects)
Left Arm: 4.5% (only one half, from the elbow to the fingers in both anterior and posterior sides).
Then TBSA = 18 + 9 + 4.5
= 31.5%.
