  "overview": [
    "Calcium is tightly regulated between roughly 8.5-10.5 mg/dL because it is essential for nerve conduction, muscle contraction, cardiac electrical stability, and bone structure. Only the ionized (unbound) fraction is physiologically active, which is why albumin levels must be considered when interpreting total serum calcium — a low albumin can make total calcium appear falsely low.",
    "Hypocalcemia produces a state of neuromuscular excitability: tetany, muscle cramps, tingling, and in severe cases laryngospasm or seizures, because low calcium lowers the threshold for nerve depolarization. Hypercalcemia does the opposite, blunting neuromuscular and cardiac excitability, producing lethargy, muscle weakness, constipation, and dangerous dysrhythmias — the classic mnemonic contrast is 'moans, groans, stones, and bones' for hyper- versus tetany and hyperreflexia for hypo-.",
    "Nursing care centers on recognizing the neuromuscular and cardiac signs early, correcting the underlying cause (parathyroid disease, renal failure, malignancy, vitamin D status, or medication effect), and replacing or lowering calcium safely, since both IV calcium and rapid correction of hypercalcemia carry their own risks."
