A nurse is caring for a client who has deep-vein thrombosis and is receiving IV fluid that contains 10,000 units of heparin in 500 mL infusing at 1000 units/hr. When calculating the client's intake and output, how much should the nurse document as intake from this infusion in an 8-hr shift? (Round the answer to the nearest whole number. Use leading zero if it applies. Do not use a trailing zero.)
