الإجابة: C. IV fluids
Severe hypercalcaemia (Ca >14) in a dehydrated patient is treated first with IV normal saline to restore volume and promote calcium excretion; bisphosphonates and calcitonin are added after. Fluids are the cornerstone of acute management. Bisphosphonates act over days and need caution with reduced creatinine clearance, so they are not the first step here.

A
ليش غلط
Calcitonin is a medication step listed after IV fluids in the acute hypercalcemia plan; she is dehydrated, so volume repletion comes first.

B
ليش غلط
Bisphosphonates reduce bone resorption to prevent further hypercalcemia; they do not correct her dehydration, which IV fluids address first.

C
ليش صح
Severe hypercalcemia with dehydration is treated first with IV fluids (normal saline), which restore intravascular volume lost through polyuria.

ليش غلط
Denosumab is presented as an osteoporosis drug (high fracture risk, CKD patients intolerant of bisphosphonates), not as the first step for dehydrated hypercalcemia.
