A patient is instructed to drink 1200 mL of water before a procedure. How many ounces is that?

• A. 30 oz
• B. 40 oz
• C. 50 oz
• D. 60 oz

Answer: (B)

Conversion between milliliters and fluid ounces uses the common approximation that 1 ounce is about 30 mL. For 1200 mL, dividing by 30 mL per ounce gives 40 ounces. This aligns with the given answer because this rounding makes the calculation clean and matches the option presented. If you use the exact conversion 1 oz = 29.57 mL, you’d get about 40.6 oz, which is still effectively represented by 40 oz in these answer choices. The other options correspond to different volumes (roughly 900 mL, 1500 mL, and 1800 mL), so they don’t fit the 1200 mL instruction.
