A nurse is preparing to administer lactated Ringer's 500 mL IV to infuse over 4 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["125"]
To calculate the infusion rate for lactated Ringer's solution, the nurse should divide the total volume of fluid by the total time of infusion.
In this case, the nurse should divide 500 mL by 4 hr, which equals 125 mL/hr.
Therefore, the nurse should set the IV pump to deliver 125 mL/hr of lactated Ringer's solution.

Explanation
To calculate the infusion rate for lactated Ringer's solution, the nurse should divide the total volume of fluid by the total time of infusion.
In this case, the nurse should divide 500 mL by 4 hr, which equals 125 mL/hr.
Therefore, the nurse should set the IV pump to deliver 125 mL/hr of lactated Ringer's solution.
Correct Answer is ["38"]
Explanation
To calculate the IV flow rate in gtt/min, the nurse needs to use the following formula: IV flow rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min).
In this case, the volume is 150 mL, the drop factor is 15 gtt/mL, and the time is 60 min.
Plugging these values into the formula, we get: IV flow rate (gtt/min) = 150 x 15 / 60.
Simplifying, we get: IV flow rate (gtt/min) = 37.5.
Therefore, the nurse should set the IV flow rate to deliver 38 gtt/min.
