一位重度糖尿病酮酸中毒（DKA）病患正在接受胰島素治療，哪項實驗室數據需要護理師最優先處理？
A patient with severe diabetic ketoacidosis (DKA) is receiving insulin therapy. Which laboratory value requires the most immediate nurse intervention?
- AGlucose 250 mg/dL血糖 250 mg/dL
- BPotassium 2.8 mEq/L✓ 正解鉀 2.8 mEq/L
- CBicarbonate 15 mEq/L碳酸氫鹽 15 mEq/L
- DpH 7.25pH 7.25
DKA 治療時胰島素會將鉀離子帶入細胞內，導致血鉀下降。低血鉀（<3.5 mEq/L）極易引發致命性心律不整。雖然血糖高、pH 值低及 HCO3- 低是 DKA 的典型表現，但低血鉀會直接威脅生命安全，必須在開始胰島素治療前糾正，否則胰島素會加劇低血鉀。
In a client with diabetic ketoacidosis (DKA) receiving insulin, a potassium level of 2.8 mEq/L requires immediate intervention due to the risk of fatal arrhythmias. Insulin drives potassium into cells, potentially worsening hypokalemia. While glucose, bicarbonate, and pH levels are expected to be abnormal in DKA, severe hypokalemia poses the most immediate life-threatening danger and must be corrected before continuing insulin therapy.
台灣臨床上針對嚴重低血鉀常有嚴格的補鉀流程與濃度限制，美國亦同，但護理師需具備更強的危急預判意識。
