A client is diagnosed with anorexia nervosa and is significantly underweight. Which of the following findings would be the highest priority for the nurse to report to the provider?
- ABradycardia with a heart rate of 52 bpm心搏過緩，心率為每分鐘 52 次
- BPotassium level of 2.8 mEq/L✓ 正解鉀離子濃度為 2.8 mEq/L
- CLanugo growth on the face and arms臉部和手臂長出細軟毛
- DAmenorrhea lasting for six months持續六個月的閉經

厭食症病人常有嚴重的電解質失衡，尤其是低血鉀（Hypokalemia）。低血鉀（鉀離子 < 3.5 mEq/L）會顯著影響心肌電生理，導致致命性心律不整（如心室顫動），這是厭食症病人死亡的主要原因之一。在所有臨床表現中，電解質異常的立即性威脅最高，因此必須優先報告給醫師，以進行緊急補鉀與監測。其他症狀如心搏過緩、毳毛生長、閉經，雖需處理，但緊急程度低於心律不整威脅。
Hypokalemia (potassium < 3.5 mEq/L) is a critical, life-threatening complication in anorexia nervosa that can precipitate fatal cardiac dysrhythmias. While bradycardia, lanugo, and amenorrhea are common findings, the electrolyte imbalance presents the most immediate threat to survival and requires urgent medical intervention.
