一位病人因糖尿病酮酸中毒(DKA)入院,護理師預期會觀察到下列何種臨床發現?
A client is admitted with diabetic ketoacidosis (DKA). Which clinical finding should the nurse expect?
- AKussmaul respirations✓ 正解庫斯莫爾呼吸
- BMetabolic alkalosis代謝性鹼中毒
- CBradycardia心搏過緩
- DWeight gain體重增加
— Explanation · 中文詳解 —
DKA 病人因體內產生大量酮體,導致代謝性酸中毒。身體為了代償 pH 值下降,會出現深而快的呼吸(Kussmaul 呼吸)以排除二氧化碳。此外,病人常伴隨脫水、多尿、體重減輕及心搏過速等症狀,非心搏過緩或體重增加。
Diabetic ketoacidosis causes metabolic acidosis due to the accumulation of ketones, prompting the body to compensate with Kussmaul respirations to expel carbon dioxide. This deep, rapid breathing is a classic sign of the respiratory compensation mechanism. Other expected findings include dehydration, tachycardia, and weight loss, whereas bradycardia and weight gain are inconsistent with the pathophysiology of DKA.
