The nurse is caring for a client infected with methicillin-resistant Staphylococcus aureus (MRSA). What’s the major infection control measure to reduce MRSA and other nosocomial pathogens in a health care setting（）
A. Using antibacterial soap when bathing clients with MRSA.
B. Conducting culture surveys periodically.
C. Ensuring that personnel wash their hands before and after contact with every client.
D. Using specific housekeeping practices for environmental cleaning.
参考答案：C
解析：
Hand washing is the major infection control measure to reduce the risk of transmission of MRSA and other nosocomial pathogens. No convincing evidence exists to support that bathing clients with antibacterial soap is effective. Culture surveys can help establish the true prevalence of MRSA in a facility but is used only to help implement where and when infection-control measures need to be implemented. Because contaminated environmental surfaces aren’t an important reservoir for MRSA, specific housekeeping practices aren’t warranted.
