A nurse is preparing to administer antibiotics 15 mg/kg/day divided equally every 12 hr. The client weighs 158 lb. How many mg should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["539"]
To calculate the medication dosage, we'll follow these steps:
Convert patient weight to kilograms:
158 lbs ÷ 2.2 lbs/kg = 71.8 kg
Determine the total daily dosage:
15 mg/kg/day × 71.8 kg = 1077 mg/day
Calculate the dosage per dose:
1077 mg/day ÷ 2 doses = 538. 5mg/dose
Round to the nearest whole number: 539 mg

Correct Answer is ["0.4"]
Explanation
To calculate the medication dosage, we'll follow these steps:
Convert the ordered dose to grams:
250 mg ÷ 1000 mg/g = 0.25 g
Determine the required volume:
0.25 g ÷ 6 g/10 mL = 0.42 mL
Round off to the nearest tenth: 0.4 mL
Correct Answer is ["18"]
Explanation
To calculate the infusion rate, we'll follow these steps:
Convert patient weight to kilograms:
220 lbs ÷ 2.2 lbs/kg = 100 kg
Calculate desired heparin dose:
18 units/kg/hr × 100 kg = 1800 units/hr
Determine infusion rate in mL/hr:
(1800 units/hr) / (25000 units/250 mL) = 18 mL/hr
