Question 19 of 20 The nurse has the following IV fluid replacement order: 1. \( 500 \mathrm{~mL} 0.9 \% \mathrm{NaCl} \) at \( 60 \mathrm{~mL} / \mathrm{hr} \). 2. NG tube to low continuous suction. 3. Replace NG drainage mL for mL every 4 hr with replacement IV of \( 500 \mathrm{~mL} \mathrm{D}_{5} / 0.45 \% \mathrm{NaCl} \). 4. Maximum IV rate is \( 100 \mathrm{~mL} / \mathrm{hr} \). In the handoff report, the nurse learns that the patient's drainage for the last 4 hours was 120 mL . The nurse begins the replacement IV fluid at 1600 . Calculate the completion time of the replacement fluid. Enter the completion time using military time.

To calculate the completion time of the replacement IV fluid, we first need to identify how much fluid is to be replaced. Since the patient had an NG drainage of 120 mL over the last 4 hours, we'll use this figure to determine the volume of the replacement IV fluid. The order states to replace the NG drainage mL for mL with a replacement IV of \( 500 \mathrm{~mL} \mathrm{D}_{5} / 0.45 \% \mathrm{NaCl} \). Therefore, the nurse will be administering an additional \( 120 \mathrm{~mL} \) of the replacement fluid. Next, the nurse is administering IV fluid at a maximum rate of \( 100 \mathrm{~mL/hr} \). 1. Determine the total volume to be administered: - This includes the initial \( 500 \mathrm{~mL} \) plus the replaced \( 120 \mathrm{~mL} \), which totals \( 620 \mathrm{~mL} \). 2. Calculate the time required to administer the replacement fluid: - Since the nurse is starting at \( 1600 \) when the IV fluid starts, we can split the calculations. - For the first \( 500 \mathrm{~mL} \): - Time = Volume ÷ Rate = \( 500 \mathrm{~mL} ÷ 100 \mathrm{~mL/hr} = 5 \mathrm{~hours} \). - After 5 hours (at \( 2100 \)), the nurse will then administer the remaining \( 120 \mathrm{~mL} \): - Time for \( 120 \mathrm{~mL} = 120 \mathrm{~mL} ÷ 100 \mathrm{~mL/hr} = 1.2 \mathrm{~hours} \) (or 1 hour and 12 minutes). Adding this to the starting time: - \( 2100 \) + \( 1 \mathrm{~hour} \) = \( 2200 \) - And then adding the remaining \( 12 \mathrm{~minutes} \) gives us \( 2212 \). Therefore, the completion time of the replacement IV fluid is **2212**.
