A nurse is preparing to administer 000 mL of lactated Ringer's IV over 6 hr. The drop factor of the manual IV tubing is 10 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 ["28"]
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.

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 ["200"]
Explanation
Understanding the Problem
We need to administer 100 mL of solution over 30 minutes.
We need to convert the rate to mL/hour.
Calculations
Convert minutes to hours:
30 minutes = 30/60 hours = 0.5 hours
Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
Infusion rate = 100 mL / 0.5 hr = 200 mL/hr
Answer
The nurse should set the IV pump to deliver 200 mL/hr.
