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?

Answer and Explanation

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.

Correct Answer is ["83"]

Explanation

To calculate the rate for an infusion pump, you would divide the total volume of fluid to be infused by the number of hours over which the infusion is to run. In this case, you have 1 liter (1,000 milliliters) of Normal Saline (NS) to be infused over 12 hours. Therefore, the rate would be 1,000 milliliters divided by 12 hours, which equals approximately 83.33 milliliters per hour. So, you would set the infusion pump to deliver at a rate of 83 milliliters per hour to ensure the 1L of NS is infused over the prescribed 12-hour period.

Correct Answer is ["0.17"]

Explanation

To calculate the infusion pump rate for Pitocin, you need to determine the concentration of Pitocin in the IV bag and then set the pump to deliver the desired dose rate. The pharmacy has added 15 units of Pitocin to a 500 mL bag. To start at 5 milliunits/min, you first convert the units of Pitocin to milliunits (15 units = 15,000 milliunits). Then, divide the total milliunits in the bag by the volume of the bag to find the concentration per mL (15,000 milliunits / 500 mL = 30 milliunits/mL). Now, to find the rate at which the pump should be set to deliver 5 milliunits/min, divide the desired dose rate by the concentration (5 milliunits/min / 30 milliunits/mL = 0.1667 mL/min). Therefore, the infusion pump should be set to approximately 0.17 mL/min.
