A nurse is caring for a client who has a new diagnosis of urolithiasis. Which of the following should the nurse identify as an associated risk factor

A. Diuretic use: Some diuretics, particularly thiazides, are actually prescribed to prevent calcium stone formation by reducing urinary calcium excretion. Diuretic use is not considered a primary risk factor for urolithiasis. B. BMI less than 25: A lower BMI is not linked with kidney stone formation. In fact, higher BMI and obesity are more commonly associated with an increased risk due to metabolic changes that affect urine composition. C. Family history: A positive family history significantly increases the risk of developing urolithiasis. Genetic predisposition and shared environmental factors contribute to stone formation, making this a strong and well-established risk factor. D. Hypocalcemia: Urolithiasis is often associated with hypercalcemia or hypercalciuria, which increase the concentration of calcium in urine and promote stone development. Hypocalcemia does not contribute to stone formation and is not a risk factor.
