Prescription: 20 mg of Drug Z per pound of child’s weight a day.

Question

Child’s Weight: 45 Kg



Issue: The parent would prefer to give a liquid medication.



You found a liquid medication that contains 0.3 grams of Drug Z per mL of solution.



Question: How many mL of the liquid medication should the child take to meet the order of the prescription? Round to 3 decimal places.

Answer 1

To calculate how many mL of the liquid medication the child should take, we first need to convert the child's weight from kg to pounds.

1 kg is approximately 2.20462 pounds.

Child's weight in pounds = 45 kg * 2.20462 = 99.20859 pounds

Now, we need to calculate the total mg of Drug Z that the child should take per day.

20 mg of Drug Z per pound * 99.20859 pounds = 1984.1718 mg of Drug Z per day

Next, we need to convert mg to grams:

1984.1718 mg * 0.001 = 1.9841718 grams of Drug Z per day

Finally, we can calculate how many mL of the liquid medication the child should take:

0.3 grams of Drug Z per mL * X mL = 1.9841718 grams

X = 1.9841718 / 0.3
X = 6.613906

The child should take approximately 6.614 mL of the liquid medication per day to meet the prescription order.
