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.)

Answer and Explanation

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.
