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
