A nurse is collecting data from a client who reports finding a new skin lesion. Which of the following actions is the nurse's priority?

A. While documenting a history of skin allergies is important for overall skin assessment, it is not the priority in evaluating a new lesion. Allergies are less immediately relevant to identifying potentially serious skin changes. B. Photographing the lesion is useful for monitoring changes over time but is secondary to obtaining critical history information about the lesion’s onset and progression. C. Identifying when the client first noticed the lesion is the priority because it provides essential information about the lesion’s duration, growth rate, and potential malignancy risk. Rapidly changing or new lesions may indicate serious conditions, such as melanoma, which require urgent evaluation. Timely assessment guides appropriate diagnostic actions and interventions. D. Instructing the client on sunscreen use is an important preventive measure, but it is not immediately relevant to assessing a newly identified lesion. The priority is to evaluate the lesion itself before discussing prevention.
