Final answer:
The assessment finding that requires nursing intervention is the expansion and change in shape of the lesion in the second picture.
Step-by-step explanation:
The assessment finding that requires nursing intervention in the client's case is A. The lesion borders have expanded and are shaped differently in the second picture.
An expanding lesion with irregular borders can be indicative of skin cancer, such as melanoma. Changes in the size, shape, or appearance of a lesion should be evaluated by a healthcare professional, as they may indicate progression or malignancy.
It's important for the nurse to assess the lesion, document the findings, and notify the healthcare provider for further evaluation and management.
