Which of the following is an appropriate treatment for vitamin D-resistant rickets?
    • Increased dietary calcium intake
    • Familial hypophosphatemic rickets (vitamin D-resistant rickets) results from the inability of the renal tubes to resorb phosphates. The calcium level is normal, and an increased dietary intake of calcium is not the appropriate treatment
    • Calcitriol
    • Familial hypophosphatemic rickets (vitamin D-resistant rickets) results from the inability of the renal tubes to resorb phosphates. The standard treatment is calcitriol
    • High-dose vitamin D supplement
    • In vitamin D-resistant rickets, the vitamin D level is normal. In vitamin D-deficient rickets, there is a low vitamin D level that is treated with high-dose vitamin D supplementation
    • Recombinant human parathyroid hormone
    • In vitamin D-resistant rickets, the parathyroid hormone levels are normal. Recombinant human parathyroid hormone is used to treat recalcitrant hypocalcemia in patients with hypothyroidism
