1. **State the problem:** We need to find the total fluid intake of a patient in milliliters (mL) over 24 hours given different volumes in ounces, pints, and liters. 2. **Recall unit conversions:** - 1 ounce (oz) = 29.5735 mL - 1 pint = 473.176 mL - 1 liter = 1000 mL 3. **Calculate each intake in mL:** - Hot tea: 1.5 cups × 12 oz/cup = 18 oz $$18 \times 29.5735 = 532.323 \text{ mL}$$ - Sports drink: 2 pints $$2 \times 473.176 = 946.352 \text{ mL}$$ - Soda: 1 liter $$1 \times 1000 = 1000 \text{ mL}$$ 4. **Add all intakes:** $$532.323 + 946.352 + 1000 = 2478.675 \text{ mL}$$ 5. **Compare with options:** The closest option is 2,420 mL. **Final answer:** b. 2,420 milliliters
