A client is being admitted for hypernatremia. A nurse is preparing to administer 0.45% sodium chloride 500 mL IV to the client over 2 hours. The nurse should set the IV pump to deliver how many mL/hr?
500
200
250
100
The Correct Answer is C
The total volume to be infused is 500 mL. The total time for the infusion is 2 hours.
The formula to calculate the IV pump rate is: Rate (mL/hr) = Total Volume (mL) / Time (hr)
Rate (mL/hr) = 500 mL / 2 hr Rate (mL/hr) = 250 mL/hr
Therefore, the nurse should set the IV pump to deliver 250 mL/hr.
