A nurse is caring for a client who has diabetic ketoacidosis. During the shift, the client received 0.45% sodium chloride IV at 500 mL/hr for 3 hr, then at 200 mL/hr for 3 hr, and then dextrose 5% in water at 75 mL/hr for 2 hr. What is the total volume the nurse should document for the client's IV fluid intake?

The correct answer is D: 2250 mL. To calculate the total volume of IV fluid intake, you need to add up the volume of each type of fluid administered over the specified durations. First, calculate the volume of 0.45% sodium chloride given at 500 mL/hr for 3 hours, which is (500 mL/hr × 3 hr) = 1500 mL. Then, calculate the volume of the same fluid given at 200 mL/hr for 3 hours, which is (200 mL/hr × 3 hr) = 600 mL. Finally, calculate the volume of dextrose 5% in water given at 75 mL/hr for 2 hours, which is (75 mL/hr × 2 hr) = 150 mL. Adding these together: 1500 mL + 600 mL + 150 mL = 2250 mL. Therefore, the nurse should document a total volume of 2250 mL for the client's IV fluid intake
