At 0800 a nurse assists with initiating a 1,000 mL IV infusion for a client, which is running at 125 mL/hr. How much fluid is left in the IV bag at 1300? (Round the ANSWER to the nearest whole number. Use a leading zero if it applies' Do not use a trailing zero.) - ANSWER 375 Step 1: What is the unit of measurement the nurse should calculate? mL Step 2: What is the total volume to be infused? Total volume = 1,000 mL Step 3: What is the rate of infusion? Rate = 125 mL/hr Step 4: What is the total infusion time so far? Time = 5 hr Step 5: Should the nurse convert the units of measurement? No Step 6: Set up an equation and solve for X. Rate (mL/hr) x Time (hr) = Volume infused (X mL) 125 mL/hr x 5 hr = X mL Volume infused = 625 mL Total volume (mL) - Volume infused (mL) = Volume remaining (mL) 1,000 mL - 625 mL = 375 mL Volume remaining = 375 mL
