A nurse started a continuous IV infusion of 1 L of normal saline (NS) at 06:57, and the infusion is completed at 15:45. What is the flow rate of infusion in this situation?
114 mL/hr
124 mL/hr
125 mL/hr
130 mL/hr
The Correct Answer is A
The infusion was started at 06:57 and completed at 15:45, which is a total time of: 15 hours and 45 minutes - 6 hours and 57 minutes = 8 hours and 48 minutes
To calculate the flow rate, we need to know the total amount of fluid infused and divide it by the total time of infusion:
1 L = 1000 mL
Total time of infusion = 8 hours and 48 minutes = 528 minutes Flow rate = Total amount of fluid infused / Total time of infusion Flow rate = 1000 mL / 528 minutes
Flow rate = 1.89394 mL/min
To convert mL/min to mL/hr, we multiply by 60:
Flow rate = 1.89394 mL/min x 60 min/hr Flow rate = 113.6364 mL/hr
Therefore, the flow rate of infusion in this situation is approximately 114 mL/hr, which corresponds to option A.

Correct Answer is C
Explanation
To dilute the enteral feeding formula to half strength, we need to add an equal volume of water to the formula. Therefore, we need to add 250 mL of water to the 250 mL of full strength formula to make a total volume of 500 mL at half strength..
So the nurse should add 250 mL of water to the formula to dilute it to half strength.
Correct Answer is B
Explanation
The correct answer is choice B. 31. To find the number of bottles required, use the formula: (dose x frequency x duration) / (bottle size x bottle concentration). In this case, (4 mg/kg x 43 kg x 3 times/day x 6 days) / (100 mg/bottle) = 30.96 bottles. Round up to the nearest whole number to get 31 bottles.
