Urinary Tract Infections · NCLEX Exam

A patient with a known lower UTI begins to experience persistent high fever and flank pain despite antibiotic therapy. The nurse should suspect:

  1. Complete resolution of the original lower urinary infection
  2. Progression to an upper UTI (pyelonephritis)
  3. Onset of an uncomplicated viral cystitis instead
  4. Transient bladder irritation from the antibiotic course
Show answer and explanation

Correct answer: Progression to an upper UTI (pyelonephritis)

Persistence or worsening of symptoms such as fever and flank pain indicate possible spread of the infection to the upper urinary tract (pyelonephritis).
