I’m tackling a medical exam question about a 10-year-old boy with polyuria, polydipsia, and lab results indicating hypernatremia. The likely diagnosis should be considered among the options. 

Diabetes insipidus matches the symptoms, featuring dilute urine and elevated serum osmolality. Renal tubular acidosis would typically show low bicarbonate; it's normal here. Bartter's syndrome usually includes hypokalemia, which isn't present. Recurrent UTIs could cause polyuria, but that doesn't explain the labs. So, I think the best choice is A: Diabetes insipidus.
