Final answer:
When a patient has MRSA, regular hand washing with soap and water is not enough. Instead, a stronger disinfectant like chlorhexidine or intranasal mupirocin should be used.
Step-by-step explanation:
If a patient has MRSA, regular hand washing with soap and water is no longer adequate. Instead, a stronger and more specific disinfectant such as chlorhexidine or intranasal mupirocin should be used. MRSA is a dangerous strain of Staphylococcus aureus that is resistant to many commonly used antibiotics, so it requires a different approach to prevent its transmission.
