A client asks the nurse to look at a mole located on the back. The client tells the nurse that the mole has changed from brown to black and enlarged in size. Which is the priority nursing action?

A. Offer to teach a family member how to monitor the skin around the mole. While monitoring for further changes is important, it does not address the immediate concern. A changing mole, especially one that darkens and enlarges, may indicate melanoma and requires prompt medical evaluation. B. Encourage the client to keep checking the mole with a magnifying mirror. Self-monitoring is useful for skin health, but in this case, a suspicious mole should be assessed by a healthcare provider rather than relying on personal observation. C. Advise the client to see his healthcare provider for immediate evaluation. A mole that changes in color and size is a warning sign of possible melanoma. Early detection and biopsy are crucial for diagnosing and treating skin cancer, making this the priority action. D. Ask the client if he often spends time outside in the sun without a shirt. Sun exposure is a risk factor for skin cancer, but identifying past exposure does not address the immediate need for professional evaluation of the suspicious mole.
