A nurse is collecting data from a hospital patient who has been admitted with pyelonephritis. He is acutely ill with a high fever, chills, nausea, and vomiting. He also has severe pain in the flank area. What is the primary goal of treatment.

Choice A rationale Providing adequate nutrition and maintaining a stable body weight is a supportive goal in the management of any acute illness. During pyelonephritis, the patient may suffer from nausea and vomiting, making oral intake difficult. However, nutritional status is a secondary concern compared to the immediate threat of systemic infection and organ damage. While important for long-term recovery, it does not represent the primary clinical objective when dealing with an acute kidney infection. Choice B rationale Pain relief is a high priority for patient comfort, as pyelonephritis causes significant distress due to inflammation of the renal pelvis. Analgesics and antispasmodics are used to manage flank pain and bladder spasms. However, treating the symptoms alone does not address the underlying pathology. Symptom management is a component of care but is subordinate to the goal of preserving the functional integrity of the renal system and preventing permanent damage. Choice C rationale The primary goal of treating pyelonephritis is to prevent permanent renal scarring and the progression to chronic kidney disease or acute renal failure. Pyelonephritis is an upper urinary tract infection that involves the kidney parenchyma. Recurrent or severe infection can lead to the destruction of nephrons. Rapid administration of antibiotics and monitoring of renal function (BUN and creatinine) are essential to ensure the kidneys remain functional and to prevent life-threatening sepsis. Choice D rationale Adequate hydration and maintaining stable vital signs are essential interventions, especially if the patient is losing fluids through vomiting or fever. Intravenous fluids help maintain renal perfusion and flush the urinary tract. While cardiovascular stability is a prerequisite for recovery, the specific focus in pyelonephritis treatment is the protection of the kidneys from the inflammatory process. Hydration supports this goal but is not the ultimate clinical end point of the therapy.
