The nurse is examining a female client who states she has no complaints and has not had a physical examination for over 5 years. The nurse palpates enlarged lymph nodes in the axilla. Which finding is most important for the nurse to describe when reporting to the healthcare provider?

A. Information about over-the-counter treatments might be relevant but is less critical than the physical findings. B. Daily caffeine consumption is unlikely to be directly related to the presence of enlarged lymph nodes. C. Having indoor cats might be relevant if there was suspicion of an infection like toxoplasmosis, but this is not the most immediate concern. D. Nontender, firm lymph nodes, especially when persistent and not related to a known infection, can be concerning and may indicate malignancy or other serious conditions. This finding should be promptly reported to the healthcare provider for further investigation.
