Question

A nurse is preparing to administer a liter of normal saline to be infused from 0700-1900. The drop factor is 20 gtts/mL. The client went for a procedure and was * disconnected from IV from 1345-1615. The client came back at 1615 and was restarted on IV fluids. How will the nurse set the IV pump rate if the fluids needs to be completed at 19007 (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

Q.1- A nurse is preparing to administer a litter of normal salaine to be infused from 07.00 to19.00.The drop factor is 20 gtts/ ml.The client went to a procedure and was disconnected from iv from 13.45-16.15. The client came back at 16.15 and was restarted to iv fluids so how will the nurse set the IV pump rate if the fluids needs to be completed at 19.00 ?

Ans- Here,plan for one liter of normal salaine to be infused from morning 7 am to evening 7 pm in drop factor 20gtts/ml.  

Rate is=Diseired volume× drop factor / time in minute

So here Diseired volume is 1litter=1000ml

Drop factor is=20 gtts/ml

Time is 12 hour=12×60= 720 min

Rate is = 1000×20/720

=27.77 drops /min

=28 drops /min approximately

If 27.77 drops /min infusion is going on then it will complete till 7pm,But infusion is going on till 3.45 pm due to procedure.

So in 27.77 drops/min is continue till 7am to 3.45pm

That is 8 hour 45min=8×60+45=525 min

So here volume to be infused is

Volume =rate ×time/ drop factor

=27.77×525 min/20

=728.96ml

=729 ml aprroxmately

729 ml fluid already transfused till 3.45 pm

Then stop fluid till 4.15pm

So it's 30 min.

Then again fluid continue till 7pm

This time is 4.15pm to 7pm= 2 hour 45 min

= 165 min

Rest of fluid volume is =1000-729

=271ml

Drop factor is =20 gtts/min

So rate is =Diseired volume× drop factor/time in min

=271×20/165

=32.84 drops/min

=33 drops / min aproxmately

So the IV pump rate is 33 drops/ min if the fluid is to completed on 07pm..
