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 ["115"]
Explanation
To determine the IV pump rate, let’s follow these steps:
Reconstitute the medication:
The concentration after reconstitution is 1 Gm/10 mL.
Since 1 Gm = 1000 mg, the concentration is 100 mg/mL.
Calculate the volume needed for the required dose:
The patient needs 1500 mg.
Using the concentration, calculate the volume: 1500/100= 15 mL
Further dilute the medication:
Add the 15 mL of reconstituted medication to 100 mL of normal saline solution (NSS).
Total volume to be infused = 15 mL + 100 mL = 115 mL.
Set the IV pump rate:
The medication is to be infused over one hour.
Therefore, the IV pump rate is: 115/1= 115 mL/ hr
Correct Answer is ["2.8"]
Explanation
To calculate the medication dosage, we'll follow these steps:
Convert patient weight to kilograms:
154 lbs ÷ 2.2046 lbs/kg = 69.84 kg
Determine the total medication dose:
40 units/kg × 69.84 kg = 2793.6 units
Calculate the volume to be administered:
2793.6 units ÷ 25000 units/250 mL = 2.8 mL
