肝臟切片（Liver Biopsy）屬於侵入性檢查，肝臟是合成多種凝血因子（如纖維蛋白原、凝血酶原）的關鍵器官。若病人存在凝血功能異常，術後極易發生無法控制的出血。護理師在術前必須確認凝血酶原時間（Prothrombin time, PT）與國際標準比值（INR）在安全範圍內，以確保檢查過程的安全性。
The liver synthesizes essential clotting factors, making prothrombin time (PT) a critical pre-procedure assessment for a liver biopsy. Checking PT ensures the client has adequate coagulation status to minimize the risk of uncontrollable bleeding during and after the invasive procedure.
