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)
Correct answer
1.3 mL
Rationale
To calculate the dosage of clindamycin, first convert the patient's weight from pounds to kilograms (88 lbs / 2.2 = 40 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 administered in two divided doses, each dose is 200 mg. The medication is supplied at 150 mg/mL, so 200 mg / 150 mg/mL = 1.33 mL, rounded to 1.3 mL per dose.
