一位感控護理師正在教導新進的無照護佐 (UAP) 關於正確的隔離預防措施。護理師提出了一個涉及感染活動性、散播型帶狀皰疹 (Herpes Zoster / Shingles) 病患的情境。UAP 的哪一句話精確地表明了對所需預防措施的正確理解?
An infection control nurse is teaching a new class of unlicensed assistive personnel (UAP) about proper isolation precautions. The nurse presents a scenario involving a client actively infected with disseminated Herpes Zoster (Shingles). Which statement by a UAP precisely indicates a correct understanding of the required precautions?
- A“I will only need a standard surgical mask and gloves, because shingles primarily spreads through large respiratory droplets.”我只需要標準外科口罩和手套,因為帶狀皰疹主要透過大型飛沫傳播。
- B“Because I had adult chickenpox recently, I am immune and completely exempt from wearing any personal protective equipment in that room.”因為我最近剛得過成人水痘,我有免疫力,完全不需要在該房間穿戴任何個人防護裝備。
- C“I only need contact precautions with hand washing unless the client is aggressively coughing, which requires airborne protocols.”除非病人劇烈咳嗽需要空氣隔離措施,否則我只需要接觸隔離和洗手。
- D“I must wear an N95 respirator, gloves, and a sterile gown, and the room must maintain negative air pressure filtration.”✓ 正解我必須佩戴 N95 呼吸器、手套和無菌長袍,且房間必須維持負壓空氣過濾。
本題測驗醫院管理中的感染控制防護層級 (Safety and Infection Control / Isolation Precautions)。帶狀皰疹 (Shingles) 是由水痘-帶狀皰疹病毒 (VZV) 重新活化所引起。一般侷限在單側皮節的帶狀皰疹,只需標準防護與接觸隔離 (Contact Precautions) 加上用敷料覆蓋即可。但是!題目中明確標註這是『散播型帶狀皰疹 (Disseminated Herpes Zoster)』。散播型的定義是其皮疹跨越了多個皮節。一旦變成散播型,病毒就具備了極高危險性的『空氣傳染 (Airborne Transmission)』能力,就如同水痘一樣!因此,法定要求必須立刻啟動最高等級防護:負壓隔離病房 (Negative pressure room)、必須戴 N95 呼吸器 (N95 respirator)、手套與隔離衣(選 D 正確)。選項 A 錯誤,飛沫傳染 (Droplet) 是不夠的。選項 B 錯誤,即使具備免疫力,依據法規無論你是誰進入 Airborne 接觸環境,都必須穿戴全套防禦裝備以防止病毒沾附衣服傳染給醫院其他免疫低下者。選項 C 錯誤,散播型的帶狀皰疹不限於咳嗽,只要皮疹中的空飄微粒被吸入就會感染。
Localized shingles requires only Standard + Contact precautions with lesions covered. However, disseminated herpes zoster (crossing multiple dermatomes) behaves like varicella with airborne transmissibility. Maximum precautions are required: negative-pressure room, N95 respirator, gown, and gloves (B correct). A is wrong — droplet precautions are insufficient. B is wrong — even immune workers must wear full PPE to prevent fomite transmission to other vulnerable patients. C is wrong — airborne shedding does not require coughing; viral particles disperse from skin lesions into ambient air.
感染控制的經典陷阱:局部 (Localized) 的帶狀皰疹只要 Contact precaution (接觸傳染)。但加上 Disseminated (散播型) 這個字,馬上無條件升級為 Airborne (空氣傳染)+負壓病房。這在台灣感控也是絕對考題。
