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. Recurrent UTIs are a major risk factor for developing pyelonephritis, as untreated or repeated lower UTIs can ascend to the kidneys. B. Chronic ibuprofen use may lead to analgesic nephropathy, but it is not directly linked to pyelonephritis. C. High calcium intake may contribute to kidney stones but is not a primary cause of pyelonephritis. D. Genetic diseases are more associated with hereditary kidney disorders (e.g., polycystic kidney disease), not typically pyelonephritis.
