Which sign indicates fever and chills in a patient with a kidney stone suggesting infection?

Fever and chills reflect a systemic infection. In a patient with a kidney stone, this combination is especially serious because an obstructed urinary tract can harbor infection that may spread to the blood, leading to conditions like pyelonephritis or urosepsis. The presence of fever and rigors signals the body's immune response to infection and typically requires urgent assessment and treatment. Hyperglycemia is high blood sugar and isn’t a direct sign of infection in this setting. Polyuria means excessive urination and can occur for various reasons, not specifically infection. Bradycardia, a slow heart rate, is not a typical sign of infection; infections usually cause tachycardia due to systemic inflammatory response.
