Question

You are caring for a 3 month old infant that weighs 6.3 kg. You have orders to administer a 2 mg/kg dose of furosemide (oral solution) for the child. You have an 8 mg/mL oral solution of pineapple flavored furosemide. STATE THE ANSWER IN SCIENTIFIC NOTATION AND CORRECT NUMBER OF SIGNIFICANT FIGURES

a. How many mL of oral solution should you administer to the infant?

b. The infant may need additional doses of furosemide, but you are not to exceed 6 mg/kg of furosemide per day. What is the maximum total daily dose (in mL) that you should administer to the infant?

Explanation / Answer

1. As we have to give 2 mg/kg body weight and weight is 6.3 kg ,so we have to give a total of 12.6 mg dose.

1 ml of oral solution contains 8 mg of furosemide so we will have to give 12.6mg/8mg/ml ,which comes out to be

1.575 ml of oral solution.

2. If maximum dose is 6 mg/kg then it will be 37.8 mg furosemide per day

So we will have to guve 37.8/8 ml

So it is 4.725 ml of oral soltution.
