A female patient with diabetes mellitus presents to the clinic with a fever of 101.0 F (38.3 C), chills, vomiting, and left flank pain. Which order should the nurse anticipate to best assess and manage this patient's condition?

Choice A rationale Fever, chills, and flank pain in a diabetic patient strongly suggest pyelonephritis, a serious upper urinary tract infection. Urinalysis and culture are essential to identify the causative organism and its sensitivity. A CBC helps assess the systemic inflammatory response, where a normal white blood cell count is 5,000 to 10,000 cells/mcL. A CT scan helps visualize renal abscesses or obstructions. Diabetes increases the risk of complicated infections, necessitating this thorough diagnostic approach. Choice B rationale Administering antiemetics treats the symptom of vomiting but does nothing to address the underlying infectious process. Delaying diagnostic testing in a diabetic patient with signs of systemic infection like a fever of 101.0 F is dangerous, as they are at higher risk for urosepsis. Prompt diagnosis is required to initiate targeted therapy. Managing symptoms is part of care, but it should never supersede the diagnostic workup required to identify a potentially life-threatening renal infection. Choice C rationale Empirical antibiotics are often started, but doing so without obtaining a urine culture first is poor practice. Once antibiotics are in the system, it becomes difficult to accurately identify the bacteria. For a patient with diabetes and signs of pyelonephritis, knowing the specific pathogen is vital because they often harbor resistant organisms. Relying solely on clinical symptoms without laboratory confirmation can lead to ineffective treatment and progression of renal damage or systemic sepsis. Choice D rationale An ultrasound of the lower abdomen alone is insufficient for a patient presenting with flank pain and systemic symptoms. Flank pain indicates an issue with the kidneys, which are in the upper urinary tract, rather than just the bladder. While ultrasound is a safe imaging modality, it should not be prioritized over essential laboratory tests like urinalysis and blood work. Furthermore, focusing only on the bladder ignores the primary site of the suspected infection.
