Question 1 of 5
A nurse is preparing to administer 0.45% sodium chloride (NaCl) 2000 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.)
Correct Answer: 250
Rationale:
To calculate the mL/hr rate, first determine the total volume to be infused over 8 hrs, which is 2000 mL. Divide 2000 mL by 8 hrs to get 250 mL/hr. This is the correct answer because it ensures the correct administration rate for the prescribed solution concentration. Other choices are incorrect because they do not accurately calculate the infusion rate based on the volume and time specified.
