Documenting a 24-hour urine collection hinges on defining the collection period and preserving the sample. Recording both the start and end times establishes the exact 24-hour window over which urine is collected, which is essential for accurate measurement of volume and analytes. Without clearly documented end time, the total collection duration is undefined and results can be misleading. Labeling the container guarantees the specimen stays with the correct patient and collection period, preventing mix-ups with other samples. Refrigerating the specimen helps maintain stability and prevents bacterial growth or degradation that could alter analyte concentrations during the collection.

These steps are why the other options don’t fit: only noting the start time doesn’t specify the full 24-hour window; times aren’t optional because the duration defines the collection; and even if the collection occurs within a single day, you still need to record both times to define the exact 24-hour period.
