慢性腎臟病（CKD）病患正在進行血液透析，哪些發現顯示其在過程中面臨併發症風險？（選所有適合的）
A client with chronic kidney disease (CKD) is receiving hemodialysis. Which findings indicate the client is at risk for complications during the procedure? (Select all that apply.)
- ABlood pressure 90/50 mmHg during dialysis✓ 正解透析期間血壓 90/50 mmHg
- BClient complains of muscle cramps✓ 正解病患主訴肌肉痙攣
- CTemperature of 98.6°F (37°C)體溫 98.6°F (37°C)
- DHeart rate of 110 beats per minute✓ 正解心跳每分鐘 110 次
- ESudden headache and nausea✓ 正解突發性頭痛與噁心
血液透析（Hemodialysis）過程中，大量血液體外循環可能引發循環系統與電解質不平衡。低血壓是透析中最常見的併發症，通常與脫水過快有關；心搏過速則是身體代償低血壓的反應；肌肉痙攣則反映了電解質（如鈣、鈉）的快速流失。透析不平衡症候群（Dialysis Disequilibrium Syndrome）則因溶質濃度快速下降導致腦水腫，出現頭痛、噁心等症狀。
During hemodialysis, the extracorporeal circulation of large volumes of blood may cause circulatory and electrolyte imbalances. Hypotension is the most common complication during dialysis and is usually related to rapid fluid removal; tachycardia is the body's compensatory response to hypotension; muscle cramps reflect the rapid loss of electrolytes such as calcium and sodium. Dialysis disequilibrium syndrome results from the rapid drop in solute concentration, leading to cerebral edema and manifesting as headache, nausea, and similar symptoms.
