護理師正在為病人進行靜脈輸注氯化鉀（KCl）。為預防併發症，護理師應評估下列哪些項目？（選所有適合的）
A nurse is caring for a client who is receiving intravenous potassium chloride. Which of the following findings should the nurse assess for to prevent complications? (Select all that apply.)
- AAdequacy of urine output✓ 正解尿量的充足程度。
- BIV site for phlebitis or infiltration✓ 正解靜脈注射部位是否有靜脈炎或滲漏。
- CSerum potassium levels✓ 正解血清鉀離子濃度。
- DCardiac rhythm✓ 正解心律。
- EPeripheral capillary refill time周邊毛細血管回填時間。
氯化鉀具有高度刺激性且過量會致死，必須嚴格監測。尿量不足會導致鉀離子滯留造成高血鉀；輸注部位若滲漏會造成組織壞死；監測血鉀確保在治療範圍；心律監測則是因為鉀離子異常會引發致命性心律不整。微血管回填時間與此處置無直接關聯。
Potassium chloride is highly irritating and can be fatal in overdose, so it must be strictly monitored. Inadequate urine output causes potassium retention and hyperkalemia; extravasation at the infusion site causes tissue necrosis; monitoring serum potassium ensures it stays within the therapeutic range; cardiac monitoring is required because potassium abnormalities can trigger lethal dysrhythmias. Capillary refill time is not directly related to this intervention.
美國多數機構規定高濃度 KCl 須經中央靜脈投予；台灣常由週邊靜脈給予但需加強稀釋。
