An client who weighs 160 pounds receives a prescription for gentamicin 5 mg/kg/day intravenously in divided doses every 8 hours. How many mg should the nurse administer with each dose?
(Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["121"]
To calculate the dosage of gentamicin for a client who weighs 160 pounds, first convert the weight to kilograms, knowing that 1 kilogram equals 2.2 pounds. The client's weight in kilograms is approximately 72.73 kg (160 ÷ 2.2).
The prescription is for 5 mg/kg/day, so the total daily dosage is 363.65 mg (72.73 kg × 5 mg). Since the medication is to be divided into doses every 8 hours, divide the total daily dosage by 3, because there are three 8-hour intervals in 24 hours.
Therefore, each dose should be approximately 121.22 mg. 121 mg rounded off to the nearest whole number.
