Which of the following assessments could indicate a urinary tract infection?

A strong ammonia-like smell in urine can indeed be an indicator of a urinary tract infection (UTI). This distinct odor is often due to the presence of bacteria in the urine, which can produce ammonia as they metabolize. In the context of a UTI, the involvement of bacteria alters the typical composition and characteristics of urine, leading to this noticeable change in smell.

In contrast, clear urine generally indicates a normal state of hydration and does not suggest an infection. A fruity odor in urine can be associated with conditions such as diabetes or ketone body presence, rather than a UTI. Low specific gravity usually suggests dilute urine, which could result from hydration or other conditions, but does not directly indicate an infection as it lacks the specific changes associated with UTIs. Thus, while several factors can influence urine characteristics, the strong ammonia-like odor is specifically aligned with the presence of a urinary tract infection.
