Order: Cefdinir 7mg / k * g po q 12 h for otitis media Available : 125mg / 5 * mL Child's weight: 60 lbs How many milliliters will you administer per day ? Show all work

1 answer

To calculate how many milliliters of Cefdinir will be administered per day, we need to convert the weight of the child from pounds to kilograms.

1 lb = 0.453592 kg
60 lbs = 60 * 0.453592 kg
60 lbs = 27.216 kg

Now we can calculate the total daily dose of Cefdinir:

Cefdinir dose per day = Cefdinir dose per kilogram * weight in kilograms
Cefdinir dose per day = 7 mg/kg * 27.216 kg
Cefdinir dose per day = 190.512 mg

Since the available concentration is 125mg/5mL, we can now calculate the volume required:

Number of milliliters per day = Cefdinir dose per day / concentration
Number of milliliters per day = 190.512 mg / 125mg/5mL

To divide by a fraction, we multiply by its reciprocal:

Number of milliliters per day = 190.512 mg * 5mL / 125mg
Number of milliliters per day = 7.62 mL

So, you will administer approximately 7.62 milliliters of Cefdinir per day.
