A nurse in an urgent care clinic is collecting data from a preschooler who reports painful urination.Which of the following findings should the nurse identify as a possible manifestation of a urinary tract infection?

Choice A rationaleMoist mucus membranes are usually a sign of adequate hydration and normal physiology. They do not indicate the presence of a urinary tract infection (UTI), which typically affects the urinary system rather than the mucus membranes. UTIs are often associated with symptoms such as painful urination, increased frequency, or fever, but not changes in mucus membrane moisture. Therefore, this finding is not a manifestation of a UTI.Choice B rationaleFacial edema is often linked to conditions involving fluid retention, such as kidney or heart dysfunction, but it is not commonly associated with urinary tract infections. UTIs primarily affect the lower or upper urinary tract, causing localized symptoms like dysuria or pyuria, rather than systemic swelling like facial edema. Therefore, facial edema is not a typical indication of a UTI.Choice C rationaleAn increased temperature or fever is a common systemic response to infection, including urinary tract infections. Fever results from the immune system activating mechanisms to fight bacterial invasion, such as Escherichia coli, a frequent causative agent of UTIs. Pyrexia occurs as cytokines signal the hypothalamus to raise the body temperature in response to infection, making this a significant finding for UTIs.Choice D rationaleMuscle twitching is usually associated with electrolyte imbalances, neurological disorders, or specific drug reactions rather than urinary tract infections. UTIs manifest symptoms more localized to the urinary tract, such as dysuria or hematuria. Muscle twitching is unrelated to the pathophysiology of a UTI and thus would not be considered a likely finding for this condition.
