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. Identify when the client first noticed the lesion: Determining the onset of the lesion helps establish a timeline for progression, which is essential in evaluating whether the lesion may be benign or malignant. Early recognition and assessment of changes in the lesion's appearance are crucial. B. Instructing the client on the use of daily sunscreen products: While sun protection is important in preventing future lesions and reducing skin cancer risk, education is not the immediate priority when initially assessing a new lesion. Evaluation and data collection come first to guide appropriate next steps. C. Photograph the lesion for the client's medical record: Photographing the lesion can aid in monitoring changes over time, but this should follow after the nurse gathers relevant subjective data such as onset, symptoms, and recent changes in the lesion. It is a helpful documentation step but not the initial priority. D. Document the client's history of skin allergies: A history of skin allergies may be helpful, especially if the lesion might be a result of contact dermatitis or other allergic reactions. However, this information is less urgent than determining when the lesion first appeared and how it has progressed.
