While assessing a client with degenerative joint disease, the nurse observes Heberden's nodes, large prominences on the client's fingers that are reddened. The client reports that the nodes are painful. Which action should the nurse take?

A. Use standard precautions and wear a mask:
The use of standard precautions is appropriate for general care to prevent the transmission of infectious agents. However, specific to MRSA, additional precautions are needed. Wearing a mask is generally not necessary unless the client has respiratory symptoms that warrant respiratory precautions.

B. Institute contact precautions for staff and visitors:
This is a correct intervention. Contact precautions involve using gowns and gloves when providing care to prevent the transmission of MRSA. It is important for both healthcare staff and visitors to adhere to contact precautions to reduce the risk of spreading the infection.

C. Explain the purpose of a low bacteria diet:
The purpose of a low bacteria diet is generally unrelated to the management of MRSA. Low bacteria diets are often recommended for individuals with compromised immune systems to reduce the risk of foodborne infections. However, it may not be directly applicable to MRSA management.

D. Monitor the client's white blood cell count:
Monitoring the white blood cell count is a relevant intervention. An elevated white blood cell count may indicate an ongoing infection or an inflammatory response. Regular monitoring helps assess the client's immune response and the potential severity of the infection.

A. Discuss approaches to chronic pain control with the client:
This is the correct answer. Heberden's nodes are bony enlargements that can occur in osteoarthritis, particularly in the joints of the fingers. These nodes can be associated with pain. Discussing approaches to chronic pain control with the client is an appropriate nursing intervention to address the client's pain and improve quality of life.

B. Review the client's dietary intake of high-protein foods:
Dietary intake of high-protein foods is not directly related to the management of Heberden's nodes in degenerative joint disease. Pain control and joint protection measures are more relevant.

C. Notify the healthcare provider of the finding immediately:
While it's important to communicate significant findings to the healthcare provider, the presence of Heberden's nodes in degenerative joint disease may not require immediate notification unless there are other concerning symptoms or complications.

D. Assess the client's radial pulses and capillary refill time:
Assessing radial pulses and capillary refill time is not directly related to managing Heberden's nodes in degenerative joint disease. These nodes are primarily a result of joint changes in osteoarthritis.
