A nurse is preparing to administer 5% dextrose in 0.45% sodium chloride 1,000 mL IV to infuse over 12 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 ["83"]
To calculate the infusion rate, you would divide the total volume of IV fluid (1,000 mL) by the number of hours over which the infusion is to be delivered (12 hours). This results in an infusion rate of 83.33 mL/hr. When rounding to the nearest whole number, the nurse should set the IV pump to deliver 83 mL/hr.
