During a skin assessment, the nurse notes a 1.5 cm irregularly shaped dark lesion with uneven borders and color variation. What should be the nurse's priority action?

Rationale: A. Reporting the finding to the provider for further evaluation is correct. The lesion’s characteristics—irregular shape, uneven borders, color variation, and size over 1 cm—are warning signs for malignant melanoma or other skin cancers. Prompt evaluation by a healthcare provider is necessary for early diagnosis and treatment, which can significantly improve outcomes. B. Documenting the lesion as an expected finding is incorrect because these features are abnormal and potentially serious, not typical skin variations. Treating it as expected could delay critical care. C. Instructing the client to apply moisturizing lotion is incorrect because moisturizers do not address abnormal pigmented lesions. This action does not prevent progression or provide diagnostic clarity. D. Reassessing the lesion during the next routine assessment is incorrect because delaying evaluation could allow a malignant lesion to grow or metastasize. Immediate reporting is the priority to ensure timely medical assessment.
