What is the characteristic of dishonest behavior in children ages 8 to 10 years?

The correct answer is choice C. Therapeutic management includes administration of gamma globulin and aspirin.

Choice A rationale:

The child's fever in Kawasaki disease is not usually responsive to antibiotics within 48 hours. Kawasaki disease is an inflammatory condition of blood vessels, and it doesn't typically respond to antibiotics. The fever associated with Kawasaki disease often persists even with appropriate treatment, and the management focuses on reducing inflammation and preventing complications.

Choice B rationale:

Aspirin is not contraindicated in Kawasaki disease. In fact, aspirin is a key component of the therapeutic management of Kawasaki disease. It is used to reduce inflammation and prevent the development of coronary artery aneurysms, a severe complication of the disease. However, the dosing of aspirin in Kawasaki disease is different from its use for pain relief, and it should be administered under medical supervision.

Choice C rationale:

Therapeutic management of Kawasaki disease does include administration of gamma globulin and aspirin. Gamma globulin is given to reduce the risk of coronary artery involvement and aneurysm formation. Aspirin, at a specific dose regimen, is used to decrease inflammation and platelet aggregation, thus preventing clot formation in the coronary arteries.

Choice D rationale:

The principal area of involvement in Kawasaki disease is not the joints. Kawasaki disease primarily affects the blood vessels, particularly the coronary arteries. The inflammation of these arteries can lead to the development of coronary artery aneurysms, which is a critical concern in Kawasaki disease. Joint involvement is not a prominent feature of this condition.

The correct answer is choice B. Cardiac valve damage.

Choice A rationale:

Pulmonary hypertension is not a common complication of rheumatic fever. Rheumatic fever primarily affects the heart, joints, skin, and brain, and pulmonary hypertension is not a typical manifestation of this condition.

Choice B rationale:

Cardiac valve damage is a common and serious complication of rheumatic fever. Rheumatic fever is caused by an autoimmune reaction to untreated streptococcal infections, particularly Streptococcus pyogenes. The immune response targets not only the streptococcal bacteria but also the body's own tissues, especially heart valves. This can lead to inflammation of the heart valves, a condition known as rheumatic heart disease. Over time, repeated bouts of rheumatic fever can result in significant damage to the heart valves, leading to valve insufficiency or stenosis. This can ultimately cause heart failure and other cardiovascular complications.

Choice C rationale:

Seizures are not a common complication of rheumatic fever. Rheumatic fever primarily affects the heart and other body systems, but it does not typically lead to seizures.

Choice D rationale:

Cardiac arrhythmias are possible complications of rheumatic fever, but they are not as common or significant as cardiac valve damage. The inflammation and scarring caused by rheumatic fever can disrupt the electrical pathways of the heart, potentially leading to arrhythmias. However, the more prevalent and severe consequence of rheumatic fever is the damage to the heart valves.
