A nurse Is preparing to infuse 2000 units/hr of heparin sodium for a client with pulmonary embolism (PO. The amount avaliabie is 25.000 250 ml bag of 0.9 sodium chloride_ How will the nurse set up the flow rate (mithr)? (Round the answer to the nearest whole Itlit.41N. uses loading zero if it applies Do not use a trading zero.)
The Correct Answer is ["20"]
Given:
Total units of heparin: 25,000 units
Total volume: 250 mL
Desired infusion rate: 2000 units/hr
Steps to solve:
Determine the infusion time:
If the nurse is infusing 2000 units/hr and has 25,000 units total, the infusion time will be:
25,000 units / 2000 units/hr = 12.5 hours
Calculate the flow rate in mL/hr:
Total volume of 250 mL needs to be infused over 12.5 hours.
The flow rate is:
250 mL / 12.5 hr = 20 mL/hr

Correct Answer is ["0.8"]
Explanation
Given:
Prescribed dose: 30 mg of enoxaparin
Available concentration: 40 mg/mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
40 mg/mL = 30 mg/X mL
Cross-multiplying gives us:
40 mg x X mL = 30 mg x 1 mL
Simplifying:
40X = 30
Solving for X:
X = 30 / 40 = 0.75 mL
Round off to the nearest tenth:
0.8mL
Correct Answer is ["8"]
Explanation
To calculate the IV flow rate in drops per minute (gtt/min:
Flowrate(gtt/min)= (Totalvolumetobeinfused× Dropfactor)/ Time(minutes)
Given:
Total volume to be infused: 150 mL
Drop factor: 10 gtt/mL
Time: 3 hours = 3 x 60 minutes = 180 minutes
Flowrate(gtt/min):
(150mL×10gtt/mL) /180 minutes
Flowrate(gtt/min):
1500gtt / 180 minutes
Flowrate(gtt/min)
8.33 gtt/min
Rounding to the nearest whole number:
8 gtt/min
