A nurse is gathering medical history from a client admitted for pyelonephritis. Which of the following should the nurse expect the client to report when asked about their medical history?

A. The client reports that they took a lot of ibuprofen for arthritis for many years.: Chronic ingestion of nonsteroidal anti-inflammatory drugs is primarily associated with analgesic nephropathy or chronic interstitial nephritis rather than acute infection. While ibuprofen affects renal hemodynamics, it does not directly predispose the renal pelvis to bacterial colonization. Pyelonephritis is typically an infectious process rather than a drug-induced inflammatory one. B. The client reports that they had two urinary tract infections (UTI) in the past 10 months.: Acute pyelonephritis most commonly results from an ascending infection where bacteria migrate from the lower urinary tract to the renal parenchyma. A history of recurrent cystitis provides a clear clinical pathway for pathogens like Escherichia coli to colonize the kidneys. Frequent infections suggest a persistent reservoir or anatomical susceptibility to microbial invasion. C. The client states that they consume a high calcium diet and have had high calcium in their blood.: Hypercalcemia and high dietary calcium are risk factors for nephrolithiasis, which involves the formation of calculi within the urinary system. While stones can cause obstruction that leads to infection, they are not a direct finding specific to the inflammatory infectious process of pyelonephritis itself. Pyelonephritis is fundamentally defined by bacterial infection of the kidney. D. The client states that they remember their mother saying their grandma had this same genetic disease.: Pyelonephritis is an acquired infectious condition caused by pathogens and is not inherited through a genetic blueprint. Genetic diseases of the kidney, such as polycystic kidney disease, involve structural mutations rather than acute bacterial inflammation. History of infection in relatives is generally coincidental or related to shared environmental factors rather than heredity.
