A nurse is admitting a 6-month-old infant who has dehydration. Which of the following amounts of urinary output should indicate to the nurse that the treatment has corrected the fluid imbalance?

Choice A reason: Intravenous immunoglobulin (IVIG) is the main treatment for Kawasaki disease, as it reduces the inflammation of the blood vessels and the risk of coronary artery aneurysms. IVIG is given as a single infusion over 10 to 12 hours, within the first 10 days of the onset of fever.

Choice B reason: Aspirin is also used to treat Kawasaki disease, as it reduces the fever, pain, and inflammation. However, it is not the first-line treatment, and it is given after IVIG to prevent thrombosis and platelet aggregation. Aspirin is given at a high dose during the acute phase, and then at a low dose until the inflammation subsides.

Choice C reason: Penicillin is not indicated for Kawasaki disease, as it is an antibiotic that treats bacterial infections. Kawasaki disease is not caused by bacteria, but by an unknown trigger that activates the immune system and causes systemic vasculitis.

Choice D reason: Acetaminophen is not effective for Kawasaki disease, as it does not reduce the inflammation or the risk of complications. Acetaminophen may be used to treat mild pain or fever, but it is not the main treatment. Moreover, acetaminophen may mask the fever and delay the diagnosis of Kawasaki disease.

Choice A reason: Retinopathy is not a potential issue for a child who has leukemia, as it is a condition that affects the blood vessels of the retina, which can be caused by diabetes, hypertension, or sickle cell disease. Leukemia does not affect the retina, but it can cause blurred vision, eye pain, or headaches due to increased intracranial pressure or cranial nerve involvement.

Choice B reason: Hemorrhage is a potential issue for a child who has leukemia, as it is a condition that causes excessive bleeding, which can be caused by thrombocytopenia, coagulopathy, or bone marrow suppression. Leukemia can cause a low platelet count, which impairs the blood clotting process and increases the risk of bleeding from minor injuries, mucous membranes, or internal organs.

Choice C reason: Neuropathy is a potential issue for a child who has leukemia, as it is a condition that affects the nerves, which can be caused by chemotherapy, radiation, infection, or compression. Leukemia can cause nerve damage, which can result in numbness, tingling, pain, or weakness in the extremities, face, or trunk.

Choice D reason: Rheumatoid arthritis is not a potential issue for a child who has leukemia, as it is a condition that affects the joints, which can be caused by an autoimmune disorder, inflammation, or infection. Leukemia does not affect the joints, but it can cause bone pain, swelling, or fractures due to bone marrow infiltration or osteoporosis.
