What physical exam finding is characteristic of urinary tract infections (UTIs)?

Suprapubic tenderness is a characteristic physical exam finding associated with urinary tract infections (UTIs) because it directly relates to the irritation and inflammation occurring in the bladder or urinary tract. When an infection is present, the bladder can become inflamed, leading to discomfort or pain localized in the suprapubic area, which is situated in the lower abdomen just above the pubic bone. This symptom is often elicited during a physical examination when pressure is applied to the area, indicating the presence of a urinary tract issue.

In the context of the other possible answers, hepatomegaly pertains to liver enlargement, which is not relevant to UTI pathology. Joint swelling could indicate various musculoskeletal conditions or inflammatory processes, but does not specifically relate to urinary tract infections. Lymphadenopathy refers to swollen lymph nodes, which might occur in various infections or systemic diseases but is not a direct finding associated with UTIs. Suprapubic tenderness stands out as the most relevant and specific indicator for this condition.
