Final answer:
The total volume of fluids the patient drank is approximately 1.125 liters. After rounding to the nearest option provided, the closest answer is 1.0 liter (option B).
Step-by-step explanation:
To calculate the metric equivalent in liters of the total amount of fluids a patient drank, which includes 1 cup of coffee, 1/2 cup of juice, and three 8-oz glasses of water, we'll use the conversion that 1 cup is approximately 0.24 liter. However, for ease of calculation, we can round this to 0.25 liters. So, 1 cup of coffee is 0.25 liters, 1/2 cup of juice is 0.25/2=0.125 liters, and three 8-ounce glasses of water (with 8 ounces being equivalent to 1 cup) is 3 * 0.25 liters = 0.75 liters. Adding these together: 0.25 liters + 0.125 liters + 0.75 liters = 1.125 liters, which can be rounded to 1.0 liter (option B) as the closest appropriate answer.
