A client is receiving IV dextrose 5% in water (D5W) at 125 mL/hour and a secondary infusion of pantoprazole 40 mg IV daily. The pharmacy provides a 110 mL premixed solution of pantoprazole to be infused over 15 minutes. The nurse should program the secondary infusion to deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["440"]
The pharmacy provides a 110 mL premixed solution of pantoprazole to be infused over 15 minutes.
First, let’s find out how many mL should be delivered per minute.
We divide the total volume by the total time in minutes:
Rate in mL/min = 110 mL /15 min ≈ 7.33 mL/min
We need to convert this to mL/hr since we want the rate in mL/hr.
There are 60 minutes in an hour, so:
Rate in mL/hr = 7.33 mL/min×60 = 440 mL/hr
So, the nurse should program the secondary infusion to deliver 440 mL/hr.

Correct Answer is ["1.5"]
Explanation
First, we need to convert the prescribed dose from mg to mcg because the available medication is labeled in mcg.
1 mg is equal to 1,000 mcg. So, 0.075 mg is equal to 75 mcg.
Given:
The prescription is for 75 mcg of levothyroxine.
The available medication is 50 mcg/tablet.
We can set up the proportion as follows:
75mcg/ xtablet = 50mcg/1tablet
Solving for x gives us the number of tablets that the nurse should administer.
Cross-multiplying and solving for x:
X = 75mcg×1tablet/50mcg
After performing the calculation, we find that x equals 1.5 tablets.
So, the nurse should administer 1.5 tablets of the medication. This is rounded to the nearest tenth as per the instructions.
Correct Answer is ["42"]
Explanation
Here's how to calculate the infusion rate (gtt/min) for the nurse to regulate:
1. Volume of azithromycin solution:
Volume = 500 mL (given)
2. Infusion duration:
Duration = 2 hours (given)
3. IV administration set gtt/mL:
Rate (gtt/mL) = 10 gtt/mL (given)
4. We need to find the rate (gtt/min) at which the solution should infuse to deliver the total volume (500 mL) over the specified duration (2 hours).
Steps:
a. Convert infusion duration from hours to minutes:
Duration (minutes) = Duration (hours) x Minutes per hour
Duration (minutes) = 2 hours * 60 minutes/hour
Duration (minutes) = 120 minutes
b. Calculate the total number of drops to be infused:
Total drops = Volume (mL) x Rate (gtt/mL)
Total drops = 500 mL * 10 gtt/mL
Total drops = 5,000 drops
c. Calculate the infusion rate (gtt/min):
Infusion rate (gtt/min) = Total drops / Duration (minutes)
Infusion rate (gtt/min) = 5,000 drops / 120 minutes
Infusion rate (gtt/min) = 41.67 gtt/min (round to nearest whole number as requested)
Therefore, the nurse should regulate the infusion at approximately 42 gtt/min.
