What is the initial management for hypercalcemia?

• A. Immediate dialysis
• B. Hydration with IV fluids
• C. Administer calcium gluconate
• D. Diuretic therapy after hydration

Answer: (B)

The first move in hypercalcemia is to restore intravascular volume with isotonic IV fluids. Rehydration improves kidney perfusion and raises the glomerular filtration rate, which promotes calcium loss in the urine (calciuresis) and lowers the serum calcium level. This step addresses a common problem in hypercalcemia—volume depletion from polyuria and poor intake—and provides a safe, rapid way to begin lowering calcium. Giving calcium would worsen the problem, so that option is not appropriate as initial therapy. Immediate dialysis is reserved for life-threatening hypercalcemia or when kidney failure prevents effective medical management, not as the first step. Diuretic therapy to boost calcium excretion is typically considered after hydration and only if volume status permits; loop diuretics can help with calcium excretion, but they’re not the initial intervention. After fluids, other treatments like calcitonin for rapid short-term reduction and bisphosphonates for longer-term control are used based on severity and the underlying cause.
