Correct Answer: A

Rationale: Monitoring the temperature of a child with minimal change nephrotic syndrome is crucial for detecting early signs of infection, a common complication in this condition. In nephrotic syndrome, the child's immune system is compromised, making them more susceptible to infections. Monitoring for fever or any changes in temperature can help healthcare providers intervene promptly to prevent further complications. Hypertension (choice B) is not typically associated with minimal change nephrotic syndrome. Encephalopathy (choice C) refers to brain dysfunction and is not a common complication of nephrotic syndrome. Edema (choice D) is a primary manifestation of nephrotic syndrome but is not typically monitored through temperature assessment.

Correct Answer: A

Rationale: Monitoring the temperature of a child with minimal change nephrotic syndrome is crucial to detect early signs of infection. Infection is a common complication in nephrotic syndrome, and fever can be an early indicator. Hypertension (choice B) is not typically associated with nephrotic syndrome. Encephalopathy (choice C) is a neurological complication and would present with altered mental status rather than a change in temperature. Edema (choice D) is a common symptom of nephrotic syndrome but is not typically monitored through temperature assessment.

Correct Answer: D

Rationale: A common clinical manifestation of bacterial meningitis is a positive Kernig sign, which indicates meningeal irritation. Kernig sign is elicited when the leg is bent at the hip and knee at 90-degree angles, and pain and resistance are felt with extension at the knee due to inflamed meninges. Options A, B, and C are not typically associated with bacterial meningitis. A rash is more commonly seen in viral illnesses, photophobia can be present but is not specific to bacterial meningitis, and jaundice is not a typical clinical manifestation of this condition.

Correct Answer: D

Rationale: The classification system of congenital heart defects into acyanotic or cyanotic defects is problematic because children with acyanotic heart defects may develop cyanosis, complicating the differentiation. Cyanosis can occur in some acyanotic defects due to various reasons such as right-to-left shunting or decreased pulmonary blood flow, making the classification based solely on cyanosis misleading. Choice A is incorrect because while the classification may involve hemodynamics, the main issue lies in the potential for acyanotic defects to develop cyanosis. Choice B is incorrect as the ease of identifying children with cyanotic defects does not address the main problem with the classification system. Choice C is also incorrect as the presence of cyanosis is not the only factor determining the classification's validity.

Correct Answer: B

Rationale: After a cardiac catheterization, the priority nursing care for a 3-year-old child is monitoring the site for bleeding. This is essential to promptly identify and address any signs of bleeding or hematoma formation, which are potential complications of the procedure. Encouraging early ambulation may be beneficial post-procedure but ensuring site integrity takes precedence. Restricting fluids until blood pressure stabilization is not a standard post-catheterization practice, as adequate hydration is crucial for recovery. Comparing the blood pressure of both lower extremities is not a priority immediate nursing action after a cardiac catheterization in a pediatric patient.
