A nurse is preparing to administer 0.9% sodium chloride 200 mL IV to infuse over 24 hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (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 ["13"]
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 ["3.3"]
Explanation
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 ["4"]
Explanation
Desired dose = 40 mg
Available concentration = 10 mg/mL
To calculate the volume to administer:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume = 40 mg / 10 mg/mL = 4 mL
