病人表現為糖尿病酮酸中毒(DKA)。護理師預期會看到何種檢驗結果?

A client presents with diabetic ketoacidosis (DKA). Which laboratory finding should the nurse expect?

  • ASerum potassium 5.5 mEq/L
    血清鉀 5.5 mEq/L
  • BSerum bicarbonate 12 mEq/L✓ 正解
    血清碳酸氫鹽 12 mEq/L
  • CArterial pH 7.50
    動脈血 pH 7.50
  • DBlood glucose 80 mg/dL
    血糖 80 mg/dL
Explanation · 中文詳解

糖尿病酮酸中毒(DKA)是因胰島素嚴重缺乏,身體被迫燃燒脂肪產生酮體,導致代謝性酸中毒。實驗室指標包括 pH 值下降(酸中毒)、碳酸氫根(Bicarbonate)消耗以緩衝酸性,數值下降;血糖顯著升高(通常 > 250 mg/dL)。鉀離子在初期因酸中毒會從細胞內移出至細胞外,呈現假性高血鉀,但體內實際總鉀量是不足的。

In diabetic ketoacidosis, metabolic acidosis occurs as the body consumes bicarbonate to buffer excess ketones, resulting in low serum bicarbonate levels. This is accompanied by decreased arterial pH and significantly elevated blood glucose.
