A nurse is preparing to administer 0.45% sodium chloride (NaCl) 1000 mL IV to infuse over 8 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 ["125mL\/hr"]
To calculate the infusion rate, the nurse should divide the total volume of fluid by the total time of infusion. In this case, the nurse should divide 1000 mL by 8 hr, which equals 125 mL/hr. Therefore, the nurse should set the IV pump to deliver 125 mL/hr of 0.45% sodium chloride (NaCl) solution.
