A nurse is caring for an infant who weighs 12 lb and is prescribed cefuroxime sodium 15mg/kg PO every 12 hr. Available is cefuroxime sodium oral solution 125mg/5mL. How many mL should 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 ["3.3"]
Step 1: Convert pounds to kilograms
1 lb is approximately 0.453592 kg
So, 12 lb is 12 X 0.453592 kg = 5.443104 kg
Step 2: Calculate the total dose of cefuroxime
The prescribed dose is 15 mg/kg
The infant weighs 5.443104 kg
So, the total dose is 15 mg/kg X 5.443104 kg = 81.64656 mg
Step 3: Determine the volume of oral solution needed
The oral solution contains 125 mg/5 mL
We need to administer 81.64656 mg
To find the volume, we can set up a proportion:
125 mg / 5 mL = 81.64656 mg / x mL
Cross-multiply: 125x = 81.64656X 5
125x = 408.2328
x = 408.2328 / 125
x ≈ 3.27 mL
Therefore, the nurse should administer approximately 3.3 mL per dose.

Correct Answer is ["13"]
Explanation
Calculations
Calculate the total minutes:
24 hours = 24 X 60 minutes = 1440 minutes
Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Total volume (mL) / Total time (min)
Infusion rate = 1200 mL / 1440 min = 0.8333 mL/min
Calculate the drip rate:
Drip rate (gtt/min) = Infusion rate (mL/min) X Drop factor (gtt/mL)
Drip rate = 0.8333 mL/min X 15 gtt/mL = 12.5 gtt/min
The nurse should set the manual IV infusion to deliver 13 gtt/min.
Correct Answer is ["28"]
Explanation
Calculate the total infusion time in minutes:
6 hours X 60 minutes/hour = 360 minutes
Calculate the total number of drops:
1000 mL X 10 gtt/mL = 10,000 gtt
Calculate the drip rate:
Drip rate (gtt/min) = Total drops / Total infusion time (minutes)
Drip rate = 10,000 gtt / 360 minutes = 27.78 gtt/min
Rounded to the nearest whole number, the drip rate is 28 gtt/min.
