How much fluid has been given if the measurement in a liter bag reads 700 ml?

If the measurement in a liter bag reads 700 ml, the amount of fluid given is 700 ml. A liter is equivalent to 1000 milliliters, so when a bag shows 700 ml, it indicates that this volume has been administered.

The other options either incorrectly convert or present the measurement. For instance, 300 ml would imply that only that much fluid remained in the bag, which contradicts the reading of 700 ml. Therefore, the correct interpretation of the fluid quantity administered is directly tied to the reading of 700 ml shown on the bag. Understanding these unit conversions and measurements is crucial in veterinary practice, especially in fluid administration to ensure proper dosing and patient care.
