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.Maintaining a saline lock is important for potential intravenous access, but it is not the most urgent priority compared to actions that directly monitor the child's condition and help manage the disease. B. 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. C. A no-salt-added diet is important to help manage fluid retention and hypertension, which are common in acute glomerulonephritis. However, while important, it does not take immediate priority over assessing the child's fluid status. D. 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.
