  • ATachycardia✓ 正解
    心搏過速
  • BBounding pulse
    脈搏強而有力
  • CDecreased skin turgor✓ 正解
    皮膚彈性減退
  • DOliguria✓ 正解
    少尿
  • EWeight gain
    體重增加
Explanation · 中文詳解

體液容積不足時,身體為了維持心輸出量會代償性增加心跳(Tachycardia);組織脫水導致皮膚彈性變差(Decreased turgor);腎臟為了保留水分會減少尿量(Oliguria)。Bounding pulse 與體重增加均為體液容積過多(Fluid Volume Excess)的特徵。

In fluid volume deficit, the body compensates to maintain cardiac output by increasing heart rate (tachycardia); tissue dehydration produces decreased skin turgor; and the kidneys conserve water, resulting in oliguria. A bounding pulse and weight gain are characteristic of fluid volume excess.

✦ 台美臨床差異

臨床上,台美對於評估脫水皆重視皮膚彈性與黏膜濕度,但在評估輕微脫水時,美國護理師更常使用毛細血管回充時間(Capillary refill)作為輔助。
