The doctor order antibiotic G 5 mg/kg/day in three divided doses. The medication is supplied 100 mg/mL. The patient weighs 120kg. What volume will the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero If it applies. Do not use a trailing zero.)
The Correct Answer is ["2.0"]
To calculate the medication dosage, we'll follow these steps:
Determine the total daily dosage:
5 mg/kg/day × 120 kg = 600 mg/day
Calculate the dosage per dose:
600 mg/day ÷ 3 doses = 200 mg/dose
Determine the volume to be administered:
200 mg ÷ 100 mg/mL = 2.0 mL

Correct Answer is ["7"]
Explanation
To calculate the infusion rate, we'll follow these steps:
Determine the concentration of insulin in the infusion:
100 units ÷ 100 mL = 1 unit/mL
Calculate the infusion rate in mL/hr:
7 units/hr ÷ 1 unit/mL = 7 mL/hr
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
