Final answer:
The nurse would suspect Kawasaki disease upon observing dry, fissured lips and a strawberry tongue in a child, as these are indicative symptoms alongside high fever and limb swelling.
Step-by-step explanation:
After completing the physical examination on a child, the nurse suspects Kawasaki disease based on evidence of dry, fissured lips and strawberry tongue. Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a childhood illness that causes blood vessels to become inflamed (vasculitis). Besides dry, fissured lips and strawberry tongue, other main symptoms include high fever lasting at least five days, rash, and swelling of the hands and feet, among others. These clinical findings are distinctive when compared to other childhood exanthems or rash illnesses such as roseola, measles, or fifth disease.
