The order from a provider is: Infuse 1L of NS over 12 hours. What will be the rate on the infusion pump?
The Correct Answer is ["83"]
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 ["2525"]
Explanation
To calculate the total intake of the client, the nurse would add up all the fluids administered over the past 9 hours. The lactated Ringer's IV, which was given at a rate of 150 mL/hr for 9 hours, totals 1350 mL. The cefazolin was administered in 100 mL of 0.9% sodium chloride, and since it's an intermittent bolus, we count it once, adding 100 mL. The two units of packed RBCs add up to 525 mL (275 mL + 250 mL). The two IV bolus infusions of 0.9% sodium chloride are 500 mL in total (250 mL each). Lastly, the famotidine was given in 50 mL of 0.9% sodium chloride. Adding all these together, the nurse should record a total intake of 2525 mL for the client over the past 9 hours.
Correct Answer is ["21"]
Explanation
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)
