Problem: The nurse is performing diabetic education with an older adult client and notes a 1-cm (0.4 inches) black raised lesion with a crusty appearance on the client's cheek. The client says it has been present for several months, has gotten larger, and never fully heals but is not painful. Which response is the nurse's priority? Ask what remedies the client has used on the lesion such as over-the-counter topical antibiotics or steroids. Ask the client about recent exposure to allergens or irritants that may have contributed to the lesion forming. Teach the client how to clean the lesion due to the increased risk for infection in clients with diabetes. Recommend the client speak to a health care provider about getting a biopsy of the lesion as soon as possible.
