What should a CNA do if they notice signs of infection in a patient?

When a CNA notices signs of infection in a patient, it is crucial to inform the supervising nurse immediately. This is because timely communication can lead to early intervention, which is vital in managing infections effectively. The supervising nurse has the training and authority to assess the situation further, order any necessary tests, and initiate appropriate treatment protocols. By alerting the supervising nurse, the CNA ensures that the patient receives prompt care, which is critical in preventing the spread of infection and ensuring the patient's health and safety.

Ignoring the signs could lead to a worsening condition, while merely documenting without further action would not provide the necessary care that the patient requires. Additionally, waiting for the patient to mention the symptoms may lead to delays in treatment, which can exacerbate the infection and compromise the patient's health. Thus, reporting the observations to the supervising nurse is the most responsible and effective action a CNA can take in this situation.
