A nurse is caring for a child who has acute glomerulonephritis. Which of the following actions is the nurse's priority?

A. Maintain a saline-lock: While maintaining a saline lock is important for ensuring vascular access in case of emergency, it is not the priority action in caring for a child with acute glomerulonephritis. Monitoring fluid balance and electrolyte levels may be necessary, but the immediate priority is to educate the parents about potential complications. B. Check the child's weight daily: Monitoring daily weight is crucial in acute glomerulonephritis, as it helps assess fluid balance and detect early signs of fluid retention or worsening kidney function, which are key concerns in this condition. This makes it a priority action. C. Place the child on a no-salt-added diet: Dietary modifications, including reducing salt intake, may be recommended for managing acute glomerulonephritis. However, it is not the priority action at this stage. D. Educate the parents about potential complications: Parental education is important for long-term management and understanding of the condition, but it is not the most immediate priority in the acute phase of the illness.
