To calculate the amount of furosemide that should be added to the fluids, we need to use the following formula:
Dose (mg/hr) = Dose rate (mg/kg/hr) × Weight (kg) × CRI (%)
First, let's calculate the dose rate:
Dose rate = 0.25 mg/kg/hr
Weight = 14 kg
Dose rate = 0.25 mg/kg/hr × 14 kg = 3.5 mg/hr
Next, let's calculate the amount of furosemide needed for the CRI:
CRI (%) = 5%
Amount of furosemide needed = CRI (%) × Fluid rate (ml/hr)
Fluid rate = 5 ml/hr
Amount of furosemide needed = 5% × 5 ml/hr = 0.25 mg/hr
Finally, let's calculate the total amount of furosemide that should be added:
Total amount of furosemide = Dose rate (mg/hr) × Duration (hours) + Amount of furosemide needed
Duration = 8 hours
Total amount of furosemide = 3.5 mg/hr × 8 hours + 0.25 mg/hr = 28 mg + 0.25 mg = 28.25 mg
Therefore, the correct answer is 28 mg.
