Which of the following describes turbid urine?

Turbid urine is characterized by its cloudiness or opacity, which means that it has suspended particles, cells, or other substances that prevent light from passing through. When describing turbid urine, stating that "print cannot be seen through it" accurately captures this observation, as the cloudiness obstructs visibility.

In contrast, completely clear urine (as described in the first choice) would indicate the absence of such particles, while being reactive to light (mentioned in the third option) is not a standard descriptor of urine characteristics. Furthermore, the assertion that turbid urine indicates normal hydration is misleading, as turbidity is often associated with various conditions, including infections, crystal formation, or the presence of substances such as protein or blood. Thus, the best description of turbid urine is that print cannot be seen through it, aligning with its diagnostic significance in AUBF measures.
