Final answer:
A nurse would document a rash with erythematous circular raised lesions as urticaria or wheals, often associated with allergic reactions or conditions like ringworm.
Step-by-step explanation:
The nurse would document a rash that has erythematous circular raised lesions as urticaria or wheals. Urticaria, commonly known as hives, is characterized by the sudden appearance of pink or red bumps on the skin, typically as part of an allergic reaction.
As seen in the case of Penny, who experienced an allergic eczema after using a new sunscreen, the skin conditions can be due to inflammation reactions or direct responses to allergens. Another potential condition described by erythematous raised lesions could be ringworm, an infection with a fungus, not an actual worm, which can present with such characteristics, as seen with 7-year-old Sarah. The nurse would consider the patient's symptoms, history, and potential exposure to allergens or infectious agents when documenting the specific type of rash.
