副甲狀腺素（PTH）的主要功能是調節鈣離子代謝。副甲狀腺機能亢進會導致 PTH 分泌過多，進而促進骨鈣吸收進入血液，造成血鈣過高。因此，監測血鈣濃度以預防高血鈣危象（如心律不整、意識改變）是護理的核心。
The main function of parathyroid hormone (PTH) is to regulate calcium metabolism. Hyperparathyroidism leads to excessive PTH secretion, which promotes calcium absorption from bone into the bloodstream, causing hypercalcemia. Therefore, monitoring serum calcium to prevent a hypercalcemic crisis (such as arrhythmia or altered mental status) is the core nursing concern.
✦ 台美臨床差異
美台臨床對高血鈣的處置原則一致，均強調輸液補充與利尿劑應用，以促進鈣質排出。
