A client is prescribed 1 g potassium phosphate IV to be infused continuously over 10 hr. Available is 1 g potassium phosphate in 250 mL dextrose 5% water (DSW). The nurse should set the IV pump to run at how many mL/hr?
The Correct Answer is ["25"]
To calculate the infusion rate for the IV pump, you would use the formula: (Total Volume in mL / Time in hours = mL/hr). For the client prescribed 1 g of potassium phosphate to be infused over 10 hours, with the available solution being 1 g in 250 mL of D5W, the calculation would be 250 mL / 10 hr = 25 mL/hr.

Explanation
To calculate the flow rate for an IV infusion, you can use the formula: (Volume in mL x Drip factor) / Time in minutes. In this case, the nurse has 500 mL of Ringer's lactate to infuse over 3 hours. First, convert the hours into minutes: 3 hours x 60 minutes/hour = 180 minutes. Next, multiply the volume by the drip factor: 500 mL x 20 gtt/mL = 10,000 gtt. Finally, divide by the total time in minutes: 10,000 gtt / 180 minutes = approximately 55.56 gtt/min. Therefore, the nurse should set the manual IV infusion to deliver around 56 gtt/min.
Correct Answer is ["25"]
Explanation
Total Penicillin dose: 3 gm (as given in the order)
Available volume: The pharmacy provides 150 mL of NS with the Penicillin already diluted.
Infusion time: 1 hour.
Rate (mL/min) = Total volume (mL) / Total time (minutes)
1 hour = 60 minutes
Rate (mL/min) = 150 mL / 60 minutes = 2.5 mL/min
Drop factor: The drip factor is 10 gtt/mL, meaning 10 drops deliver 1 mL of solution. Rate (gtt/min): To find the rate in gtt/min, multiply the rate (mL/min) by the drip factor (gtt/mL).
Rate (gtt/min) = Rate (mL/min) x Drip factor (gtt/mL)
Rate (gtt/min) = 2.5 mL/min x 10 gtt/mL = 25 gtt/min
