can someone help with these nusing dosage calculations problems The following orders are for one patient. Follow the directions in each numbered question. D5/RL 3000 mL IV, q24h Penicillin G 2.5 million units IVPB q4h, mixed as 3.2 mL in 100 mL D5W to run over 1 hour. (reconstituted dose is 1,000,000 units/mL) Zithromax 500 mg IV daily for 2 days. The 500 mg vial is mixed with 4.8 mL and added to 250mL of D5W, and administered over 90 minutes. Drop factor for the penicillin is 15. What's the flow rate in gtt/min? How many mL/hour will you set the infusion pump for the Zithromax? What will the flow rate for the maintenance IV of D5/RL be to infuse all of the required fluids within 24 hours?Explanation / Answer
9.)
Total Volume = 3.2 + 100 = 103.2 mL
drop factor = 15 gtts/ml (given)
Time = 1 hour = 60 minutes
Calculation :
flow rate = [total no of milliliters (volume)/ total no of minutes (time) ] x drop factor
= (103.2/60)*15
= 25.8 gtt/min
10.)
Total Volume = 4.8 + 250 = 254.8 mL
Use of an infusion pump (equivalent of drop factor of tubing) = 60 gtts/ml (known)
Time = 90 minutes
Calculation :
flow rate = [total no of milliliters (volume)/ total no of minutes (time) ] x drop factor
= (254.8/90) *60 = 169.86 gtt/min
We know,
1 gtt/min = 3.00 mL/h
So, flow rate = 169.86*3 = 509.58 mL/ hour
11.)
Calculating Flow rate: :
Flow rate : is the number of drops per minute to be infused (gtt/min).
Drop factor = 60 gtt/ mL (Since infuse)
Formula:
flow rate = [total no of milliliters (volume)/ total no of minutes (time) ] x drop factor
Here,
Critical information:
Volume = 3000 ml
Time = 24 hours
Drip factor of tubing = 60 gtt/ml.
Time = 24 (hr) x 60 (minutes) = 1440 minutes
Flow rate = (3000 ml /1440 minutes)X60 gtt/mL
= 125 gtt/ min
