下列哪一位病人應優先安排至單人病房，以防止感染傳播？
Which of the following clients should be prioritized for a private room to prevent transmission of infection?
- AClient with a history of chronic cholecystitis有慢性膽囊炎病史的病人
- BClient with a localized fungal infection of the skin患有局部皮膚黴菌感染的病人
- CClient with a confirmed diagnosis of hepatitis A確診為A型肝炎的病人
- DClient with a draining wound with MRSA✓ 正解患有MRSA（耐甲氧西林金黃色葡萄球菌）且傷口有引流的病人
此題核心在於「傳染途徑的防護（Transmission-based Precautions）」。MRSA（耐甲氧西林金黃色葡萄球菌）主要透過接觸傳播，當傷口有引流液時，環境污染風險極高，必須執行接觸隔離（Contact Precautions），單人病房能有效阻隔交叉感染。臨床思路應優先考量病原體在環境中的存活能力與傳播風險。
A client with a draining wound infected with MRSA requires a private room to implement contact precautions and prevent the spread of this multidrug-resistant organism through environmental contamination. Unlike non-infectious conditions or those with lower transmission risks, active drainage significantly increases the potential for cross-infection in shared spaces.
美國醫院對於 MRSA 的篩檢與隔離（Isolation）規範極為嚴格，通常會針對 MRSA 陽性病人進行主動篩檢（Active Surveillance），且一旦確診，單人房或同病原體安置（Cohorting）是強制性政策。
