A nurse is preparing to administer 12 L lactated Ringer’s IV to infuse over 24 hr. Half of the fluid is to be administered in the first 8 hr. The nurse should set the IV pump to deliver how many mL/hr during the first 8 hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) ________ mL/hr

Step 1 is to convert the total volume from Liters (L) to milliliters (mL) Total mL = 12 × 1,000 12 × 1,000 = 12,000 mL Step 2 is to calculate the volume to be administered in the first 8 hours (half of the total) Volume for first 8 hr = 12,000 ÷ 2 12,000 ÷ 2 = 6,000 mL Step 3 is to calculate the flow rate in mL per hour mL/hr = Volume ÷ Time 6,000 ÷ 8 = 750 Step 4 is to round to the nearest whole number 750 = 750 Answer: 750
