32. A 10-year-old boy is brought to the physician
because of
weakness and decreased appetite for 3 months. He
weighs 30 kg (66 lb) and is
142 cm (56 in) tall; he has had a 2.3-kg (5-lb) weight
loss since his
last examination 6 months ago. He appears thin. Deep
tendon reflexes
are brisk. Chvostek's sign is positive. His serum
calcium level is 6.5
mg/dL, and serum intact parathyroid hormone level is
190 pg/mL
(N=9–65). In addition to calcium supplementation,
which of the following is
the most appropriate next step in management?

A
) Oral phosphate supplementation

B
) Oral vitamin D supplementation

C
) Intranasal calcitonin therapy

D
) Parenteral bisphosphate therapy

E
) Parenteral parathyroid hormone therapy

I went for Oral Vit D supplements but i aren't sure

Well couple of solutions say it's bisphosphonates but i don't agree . They are DoC for Paget's, this guy certainly has secondary hyperPTH mostly due to Rickets. Thanks!
