The nurse must prepare an oral contrast solution in 850 mL of apple juice. There are 6-ounce containers of apple juice in the pantry. What is the minimum number of containers of juice to make 850 mL? (Round the answer to the nearest whole container)

To prepare 850 mL of apple juice, we convert mL to ounces (1 mL = 0.033814 oz). So, 850 mL = 850 * 0.033814 = 28.78 oz. As each container is 6 oz, we divide 28.78 by 6 to find the minimum number of containers needed, which is approximately 4.8. Since we have to round up to the nearest whole container, we need 5 containers. Therefore, the correct answer is 5.

Choice A: Incorrect, as it does not account for the correct conversion and rounding needed.
Choice B-G: These choices are incorrect as they do not follow the proper conversion and rounding steps, leading to inaccurate results.
