A nurse is reinforcing teaching to a group of parents about potential causes of autism spectrum disorder (ASD). Which of the following statements should the nurse reinforce?

A. Recommending early intervention services for developmental support within the first month after birth. Early intervention is critical for children with Down syndrome to support cognitive, motor, and social development. Services such as physical therapy, speech therapy, and occupational therapy should begin as soon as possible to maximize the child's developmental potential.

B. Suggesting the parents consider genetic testing to guide future reproductive decisions. While genetic counseling can be beneficial for family planning, this is not the immediate priority for parents who are just beginning to care for their newborn with Down syndrome. The focus should be on supporting the child's development and parental education.

C. Encouraging the parents to research advancements in treatments for Down syndrome independently. While learning about Down syndrome is important, parents should receive guidance from healthcare professionals and support organizations rather than being left to navigate information on their own. Providing credible resources is more appropriate.

D. Providing the parents with a list of local pediatricians for well-child check-ups and vaccinations. While pediatric follow-ups are necessary, Down syndrome care goes beyond standard well-child visits. A more comprehensive approach includes early intervention services, specialty care (e.g., cardiology, ENT), and developmental support.

A. "Kawasaki disease is an abnormal immune response that only affects the liver." This is incorrect. Kawasaki disease primarily affects the blood vessels, especially the coronary arteries, not just the liver. While liver inflammation can occur, it is not the main concern.

B. "Kawasaki disease is an abnormal immune response that causes injury to the body's muscles." This is incorrect. Kawasaki disease is a vasculitis (inflammation of blood vessels), not a muscle disorder. It mainly affects the heart and blood vessels, potentially leading to aneurysms and long-term cardiac complications.

C. "Kawasaki disease is an abnormal immune response in which the body attacks the skin only." This is incorrect. While skin changes (such as a rash, peeling skin, and red palms/soles) are common symptoms, the primary concern is inflammation of the coronary arteries, which can lead to serious heart complications.

D. "Kawasaki disease is an abnormal immune system response that can weaken the coronary arteries." This is correct. Kawasaki disease triggers inflammation in medium-sized arteries, particularly the coronary arteries, which supply blood to the heart. If untreated, this can lead to coronary artery aneurysms, myocardial infarction, or long-term heart disease.
