A client diagnosed with acute pyelonephritis is still experiencing burning with urination after 24 hours of antibiotic therapy. What medication should the nurse anticipate being prescribed next?

When a client with acute pyelonephritis continues to experience burning with urination despite 24 hours of antibiotic therapy, it indicates that while the infection is being treated, there may still be significant irritation of the urinary tract. Phenazopyridine is a urinary analgesic that specifically alleviates burning, urgency, and frequency associated with urinary tract infections. It works by providing a soothing effect on the mucosal lining of the urinary tract, which can significantly improve the patient's comfort while the antibiotics take effect.

In this scenario, it is essential to address the symptomatic relief of urinary discomfort in conjunction with the infection treatment. Continuing with antibiotics alone without managing the painful symptoms might not be optimal for patient care. Therefore, the introduction of phenazopyridine provides a necessary adjunctive therapy.

The other medications mentioned have different primary uses: Amoxicillin and Ciprofloxacin are both antibiotics, which may be beneficial if the current antibiotic is ineffective, but they do not directly relieve pain or discomfort. Furosemide is a diuretic and is used to manage conditions associated with fluid retention; it would not address the symptom of burning with urination. Thus, phenazopyridine is the most appropriate choice for alleviating the burning sensation
