A physician prescribes clindamycin 10 mg/kg/day IV in two divided doses for respiratory tract infection. The medication is supplied 150 mg/mL. The patient weighs 88 lbs. How much will the nurse administer per dose? (round to the nearest tenth)
The Correct Answer is ["1.3"]
To calculate the dosage of clindamycin, first convert the patient's weight from pounds to kilograms, knowing that 1 kg equals 2.2 lbs. The patient weighs 88 lbs, which is equivalent to 40 kg (88 lbs / 2.2 lbs per kg). The prescribed dose is 10 mg/kg/day, so the patient requires 400 mg/day (10 mg/kg * 40 kg). Since the medication is to be administered in two divided doses, each dose will be half of the daily requirement, resulting in 200 mg per dose. The medication is supplied at a concentration of 150 mg/mL, so to find out how many milliliters per dose, divide the dose in milligrams by the concentration: 200 mg / 150 mg/mL, which equals 1.33 mL. Rounded to the nearest tenth, the nurse will administer 1.3 mL per dose.
