護理師照護一位感染困難梭狀芽孢桿菌的病人，應執行哪種防護措施？

核心概念：困難梭狀芽孢桿菌（Clostridioides difficile, C. diff）感染的隔離措施。 為何正確答案對： B. C. diff 是一種透過接觸傳播（Contact Transmission）的感染。其產生的孢子（Spores）對酒精消毒具有抗性，因此標準預防措施（Standard Precautions）不足以完全防護。必須採取接觸隔離（Contact Precautions），這包括進入病室時穿戴隔離衣和手套，離開病室後徹底洗手（使用肥皂和流水，而非僅酒精乾洗手），並對共用設備進行嚴格消毒。台灣的醫療機構多採此標準。

Core concept: isolation measures for Clostridioides difficile (C. diff) infection. Why the correct answer is correct: B. C. diff is transmitted via contact transmission. The spores it produces are resistant to alcohol-based disinfectants, so standard precautions alone are insufficient. Contact precautions are required, including donning gown and gloves when entering the room, performing thorough hand hygiene with soap and running water (not alcohol-based hand rub alone) after leaving the room, and rigorously disinfecting any shared equipment. This is the standard practiced in healthcare facilities in Taiwan.
