A nurse is to give Fortaz to a child at an amount of 50.0 mg per kilogram of body weight. The child weighs 56.1 pounds. Fortaz is available in an oral suspension labeled 100 mg/mL. How many mL would the nurse give ? (1 kg = 2.2 pounds)
Ans:
Given:
Ordered recommended dose=50 mg /kg
Dose on hand=100 mg/ml
Weight of child=56.1 pounds
Solution:
Convert pounds to kg
Divide pounds by 2.2
56.1÷2.2 = 25.5 kg
Therefore weight of child = 25.5 kg
Dose of child = weight × Recommended dose
= 25.5 × 50 = 1275 mg
If 1 ML contains 100 mg
Then x ML contains 1275 mg
Cross multiplication;
1 × 1275 = 100 × x
Therefore ;
X= 1275 ÷ 100 = 12.75 ml
Therefore nurse should give 12.75 ml Fortaz to the child.
