A nurse is administering medications to a client who weighs 132 lb. The prescription reads chloramphenicol, 50mg/kg/day in 4 divided doses. Available is chloramphenicol 100 mg/mL. How many mL should the nurse give with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["7.5"]

Convert the client's weight from pounds to kilograms. We can use the formula 1 kg = 2.2 lb. So, 132 lb / 2.2 = 60 kg.

Calculate the total daily dose of chloramphenicol for the client. We can use the formula Dose (mg) = Weight (kg) x Dosage (mg/kg). So, 60 kg x 50 mg/kg = 3000 mg.

Divide the total daily dose by 4 to get the dose for each administration. So, 3000 mg / 4 = 750 mg.

Calculate the volume of chloramphenicol solution needed for each dose. We can use the formula Volume (mL) = Dose (mg) / Concentration (mg/mL). So, 750 mg / 100 mg/mL =

7.5 mL.

Round the answer to the nearest tenth. So, the nurse should give 7.5 mL of chloramphenicol solution with each dose.

Correct Answer is ["500"]

Explanation

To calculate the dose of erythromycin per administration, you can follow these steps:

- Determine the total daily dose: 2 g.

- Divide the total daily dose by the number of equally divided doses per day: 2 g / 4 doses =

0.5 g per dose.

- Convert grams to milligrams: 0.5 g * 1000 mg/g = 500 mg.

So, the nurse should administer 500 mg of erythromycin per dose.
