The order from a provider is: 1.5 liters of LR to infuse over 18 hours. The drip factor is 15 gtt/mL. How many gtt/min?

Answer and Explanation

The Correct Answer is ["21"]

Total volume to be infused: 1.5 liters (as given in the order)

1 liter = 1000 mL

Total volume (mL) = 1.5 liters x 1000 mL/liter = 1500 mL

Infusion time: The solution needs to be infused over 18 hours.

Total time (minutes) = Total time (hours) x Minutes/hour

Total time (minutes) = 18 hours x 60 minutes/hour = 1080 minutes

Rate (mL/min): Calculate the volume to be infused divided by the total time in minutes. Rate (mL/min) = Total volume (mL) / Total time (minutes)

Rate (mL/min) = 1500 mL / 1080 minutes = 1.39 mL/min (rounded to two decimal places)

Drip factor: The drip factor is 15 gtt/mL, meaning 15 drops deliver 1 mL of solution. Rate (gtt/min) = Rate (mL/min) x Drip factor (gtt/mL)

Rate (gtt/min) = 1.39 mL/min x 15 gtt/mL = 20.85 gtt/min = 21 gtt/min (rounded to the nearest whole number)

Correct Answer is ["25"]

Explanation

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.
