一位病患出現糖尿病酮酸中毒(DKA),預期會出現何種實驗室檢測結果?
A client presents with diabetic ketoacidosis (DKA). Which laboratory finding is expected?
- APaCO2 50 mmHgPaCO2 50 mmHg
- BSerum bicarbonate 28 mEq/L血清碳酸氫鹽 28 mEq/L
- CSerum pH 7.25✓ 正解血清 pH 7.25
- DBlood glucose 150 mg/dL血糖 150 mg/dL
— Explanation · 中文詳解 —
DKA 典型的血液檢查結果為代謝性酸中毒,pH 值小於 7.35。碳酸氫根濃度通常會低於 15 mEq/L,而非 28(正常為 22-26)。血糖通常遠高於 250 mg/dL。PaCO2 呈現代償性降低以緩解酸中毒,而非上升。pH 7.25 符合代謝性酸中毒特徵。
Diabetic ketoacidosis (DKA) is characterized by metabolic acidosis, resulting in a serum pH below 7.35, such as 7.25. This condition typically presents with significantly elevated blood glucose (>250 mg/dL), decreased serum bicarbonate (<15 mEq/L), and compensatory low PaCO2 due to hyperventilation.
✦ 台美臨床差異
無差異,DKA 之實驗室診斷標準在全球護理教育中一致。
