Final answer:
Contact precautions should be used for a client with MRSA in a wound bed to prevent the spread of this highly contagious and antibiotic-resistant bacterium.
Step-by-step explanation:
The nurse should institute Contact precautions for a client with a wound bed colonized by methicillin-resistant Staphylococcus aureus (MRSA). MRSA is a highly contagious bacterium that is resistant to many antibiotics and can cause serious infections. It can be transmitted through skin-to-skin contact and by coming into contact with contaminated surfaces. In health-care settings, close contact can easily spread MRSA, making Contact precautions essential to prevent transmission to health-care providers and other patients.
