Final answer:
To convert 2 liters to cups, divide 2 liters by the cup equivalent of 0.24 liters. The patient can drink about 8.33 cups a day within the 2-liter fluid restriction.
Step-by-step explanation:
The student is asking how many cups of fluid they can drink daily if they need to restrict their intake to 2 liters every 24 hours, and they have only household measuring cups. Considering that 1 cup is approximately equal to 0.24 liters, to find out how many cups are in 2 liters, we would divide 2 liters by 0.24 liters per cup.
2 liters / 0.24 liters/cup = 8.33 cups (rounded to two decimal places)
So, the patient can drink about 8.33 cups of fluid daily without exceeding the 2-liter restriction. It is, however, important to remember that cups can come in slightly varying sizes and the conversion is based on a standard U.S. cup measurement.
