 | . 大三上 (2021/09/30): (A)正確，Vitamin A intoxication之高血鈣為high bone turnover之hypercalcemia，因此PTH level應該較低 (B) 正確，高血鈣最常見的兩個原因為惡性腫瘤及PTH Whenever hypercalcemia is confirmed, a definitive diagnosis must be established. Although HPT, a frequent cause of asymptomatic hypercalcemia, is a chronic disorder in which manifestations, if any, may be expressed only after months or years, hypercalcemia can also be the earliest manifestation of malignancy, the second most common cause of hypercalcemia in the adult. The causes of hypercalcemia are numerous but HPT and cancer account for 90% of all cases. (C)正確，lithium可能造成parathyroid hyperplasia，因此造成高血鈣 (D)錯誤，會降低血中PTH,及Calcium level, 但也會造成adynamic bone disease，無法改善骨密度 | 檢舉 |
