What is the primary result of anemia?
Depressed hematopoietic system.
Presence of abnormal hemoglobin.
Decreased oxygen-carrying capacity of blood.
Increased blood viscosity.
The Correct Answer is C
The correct answer is choice C. Decreased oxygen-carrying capacity of blood.
Choice A rationale:
Anemia does not primarily result in a depressed hematopoietic system. In fact, anemia often occurs due to various factors that affect red blood cell production or lifespan. The hematopoietic system can be overactive in response to anemia, attempting to compensate for the reduced oxygen-carrying capacity of the blood.
Choice B rationale:
While some anemias may involve the presence of abnormal hemoglobin (e.g., sickle cell anemia), this is not the primary result of anemia. The primary consequence of anemia is a decreased ability of the blood to carry oxygen to the body's tissues.
Choice C rationale:
The correct choice. Anemia leads to a decreased oxygen-carrying capacity of the blood. Hemoglobin, the protein in red blood cells responsible for carrying oxygen, is reduced in quantity or function in various types of anemia. This results in inadequate oxygen delivery to tissues, potentially causing symptoms such as fatigue, weakness, pallor, and shortness of breath.
Choice D rationale:
Increased blood viscosity is not a primary result of anemia. Anemia tends to reduce blood viscosity because there are fewer red blood cells and less hemoglobin present, which makes the blood more fluid and less viscous. Increased blood viscosity is more commonly associated with conditions like polycythemia, where there is an excess of red blood cells.

Correct Answer is C
Explanation
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.
Correct Answer is C
Explanation
The correct answer is choice C: Administering penicillin.
Choice A rationale:
Imposing strict bed rest for 4 to 6 weeks. This choice is not the most appropriate therapeutic management for rheumatic fever. While rest is important during the acute phase, strict bed rest for 4 to 6 weeks is excessive and could lead to physical deconditioning and psychological distress for the child.
Choice B rationale:
Administering corticosteroids if chorea develops. This choice is relevant to the management of rheumatic fever but is not the primary treatment. Chorea is a movement disorder that can occur as a complication of rheumatic fever. Corticosteroids may be used to manage chorea symptoms, but they are not the mainstay of treatment for rheumatic fever itself.
Choice C rationale:
Administering penicillin. This is the correct choice. Penicillin is the mainstay of treatment for rheumatic fever. It helps eradicate the group A streptococcal infection that triggers the inflammatory response leading to rheumatic fever. Penicillin is essential to prevent further complications such as rheumatic heart disease.
Choice D rationale:
Avoiding salicylates (aspirin). This choice is also relevant to the management of rheumatic fever. Salicylates, including aspirin, are used to relieve symptoms and reduce inflammation. However, in children with acute rheumatic fever, salicylates are contraindicated due to the risk of developing Reye's syndrome, a serious condition that affects the brain and liver.
