What is the nurse's priority action for a client undergoing radiation therapy with concerning laboratory results?

• A. Initiate a pain management protocol.
• B. Encourage increased fluid intake.
• C. Initiate reverse isolation precautions.
• D. Schedule a follow-up appointment.

Answer: (C)

In the context of a client undergoing radiation therapy, one of the significant risks is the potential for immunosuppression due to damage to bone marrow, which can result in decreased white blood cell counts. This condition places the patient at an increased risk for infections. In such scenarios, implementing reverse isolation precautions becomes critical. Reverse isolation is a method of protecting a vulnerable patient from exposure to potential pathogens in the environment, which is especially important when laboratory results indicate neutropenia or other signs of diminished immune function.

By prioritizing reverse isolation precautions, the nurse significantly helps in minimizing the risks of infection, which is crucial for the client’s safety and recovery. This action not only helps protect the patient from external infections but also supports their overall health during a period when their immune system may be compromised.

In contrast, while pain management and fluid intake are certainly important aspects of care and may address specific symptoms, they do not directly mitigate the immediate risk of infection that arises from the concerning laboratory results. Scheduling a follow-up appointment is important for ongoing care but does not provide the immediate protective measures that reverse isolation does in response to underlying laboratory findings.
