An infant needs 10 mg/kg of an antibiotic. The infant weighs 11 lbs. The antibiotic is available as a 100 mg/10 mL suspension. What is the weight of the infant in kilograms (kg)? How much antibiotic in milligrams (mg) is needed by the infant? How many milliliters (mL) of suspension is needed to be administered to the infant per dose?
Use Factor Method in solving the problems:
Step 1. Using the following equation, determine the factor that defines the multiple or the decimal fraction of the amount of formula to be prepared:
Quantity of formula desired/Quantity of formula given = Factor
A factor greater than 1 represents the multiple of the formula, and a factor less than 1 indicates the fraction of the formula to be prepared.
Step 2. Multiply the quantity of each ingredient in the formula by the factor to determine the amount of each ingredient required in the reduced or enlarged formula.
