Correct Answer: C

Rationale: Erythema of the hands and feet is a key diagnostic criterion for Kawasaki disease. This, along with other symptoms like fever and strawberry tongue, helps in making the diagnosis. While desquamation of the palms and soles, cervical lymphadenopathy, and strawberry tongue are associated with Kawasaki disease, the presence of erythema of the hands and feet is particularly significant in diagnosing this condition.

Correct Answer: A

Rationale: In infants, laughing readily and turning from back to side are developmental milestones that indicate effective thyroid therapy and normal development. These actions demonstrate improved muscle tone, coordination, and overall growth, which are key indicators of successful treatment for hypothyroidism in infants. Choices B, C, and D describe behaviors that are not specific indicators of thyroid therapy effectiveness in treating hypothyroidism in infants.

Correct Answer: C

Rationale: In a child with pneumonia who is breathing rapidly, the priority action for the nurse is to start the child on oxygen therapy. This intervention is essential to ensure adequate oxygenation, which is crucial in managing respiratory distress and preventing complications associated with hypoxia. Administering antipyretic medication (Choice A) may help reduce the fever but does not address the immediate need for oxygen therapy. Obtaining a chest X-ray (Choice B) is important for diagnosis but providing oxygen is more urgent. Notifying the healthcare provider (Choice D) can be done after initiating oxygen therapy to update on the patient's condition.

Correct Answer: A

Rationale: Corrected Question: The healthcare provider plans to screen only the highest risk children for scoliosis. Which group of children should the healthcare provider screen first? Girls between ages 10 and 14 are at the highest risk for scoliosis and should be screened first as they have a higher incidence of developing scoliosis during their adolescent growth spurt. Early detection and intervention can help prevent further complications associated with scoliosis. Boys between ages 10 and 14 (choice B) are not at the highest risk compared to girls in the same age group. Boys and girls between 12 and 14 (choice C) are at a lower risk compared to girls between ages 10 and 14. Boys and girls between 8 and 12 (choice D) are at a lower risk group compared to girls between ages 10 and 14.

Correct Answer: A

Rationale: In a child with acute glomerulonephritis, hypertension is the most concerning assessment finding as it can indicate worsening renal function. Hypertension is a common complication of glomerulonephritis and can lead to further kidney damage if not managed promptly. Monitoring and controlling blood pressure is crucial in these cases to prevent complications and preserve renal function. Gross hematuria, proteinuria, and periorbital edema are also common findings in acute glomerulonephritis but hypertension poses a higher risk for renal damage if left uncontrolled.
