Question

The physician orders Fortaz 50mg/kg PO TID to a child that weighs 25.5kg. Fortaz is available in an oral suspension labeled 100mg/mL. How many mL would the nurse administer per day?

Answer 1

The nurse should administer a total of 12.75 mL of Fortaz oral suspension per day to the child, with each dose being 4.25 mL.

Step-by-step explanation:

To calculate the amount of Fortaz suspension the nurse should administer per day, you first determine the total daily dosage by multiplying the prescribed dosage by the child's weight:

50 mg/kg × 25.5 kg = 1275 mg/day

This is the total amount of medication the child needs in one day. The physician has prescribed this medication to be taken three times a day (TID), so you'll need to divide the total daily dose by three to get the amount for each dose:

1275 mg/day ÷ 3 doses/day = 425 mg/dose

Next, convert the mg dose to mL using the concentration of the Fortaz suspension, which is 100 mg/mL:

425 mg/dose ÷ 100 mg/mL = 4.25 mL/dose

Finally, to find the total volume administered per day, multiply the volume per dose by the number of doses per day:

4.25 mL/dose × 3 doses/day = 12.75 mL/day

The nurse would administer a total of 12.75 mL of Fortaz per day.
