    Calculation

    A nurse is calculating the client's net fluid balance at the end of the 8 hour shift. The nurse notes the following: client voided 400 mL at 1100 and 350 mL at 1430. The closed chest drainage system was previously marked at 155 mL and is now at 175 mL. The NG tube has 575 mL in the drainage container and 25 mL was emptied out of the Jackson-Pratt drainage tube. The patient is receiving 1/2 NS at 100 mL/hr. How many mL would the nurse record as the client's net fluid balance for this shift? Round to the nearest whole number. Record numeric answers only. Enter a + prior to the value if the value is positive, Enter a - prior to the answer if the value is negative.

    mL

    Explanation & Rationale

    Calculation: Calculate total fluid intake IV fluids: 100 mL/hr × 8 hr = 800 mL Calculate total fluid output Urine output: 400 + 350 = 750 mL Chest drainage: 175 − 155 = 20 mL NG tube drainage: 575 mL Jackson-Pratt drainage: 25 mL Total output = 750 + 20 + 575 + 25 = 1,370 mL Calculate net fluid balance Net balance = Intake − Output Net balance = 800 − 1,370 = −570 mL
