A nurse is preparing to administer lactated Ringer's 1,500 mL IV to infuse over 8 hr to a pregnant client who has gastroenteritis. 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.)

Given: Total volume: 1500 mL Time: 8 hours Steps to solve: Determine the flow rate: Set up a proportion to solve for the unknown flow rate (X): 1500 mL/8 hr = X mL/1 hr Cross-multiplying gives us: 1500 mL x 1 hr = 8 hr x X mL Simplifying: 1500 = 8X Solving for X: X = 1500 / 8 = 187.5 mL/hr Round to the nearest whole number: 188 mL/hr.
