What action is essential for a nurse caring for a child with acute glomerulonephritis?

Monitoring daily weight is essential for a nurse caring for a child with acute glomerulonephritis because weight changes can provide critical information about the child's fluid status and kidney function. Acute glomerulonephritis can lead to fluid retention due to impaired renal function, resulting in edema and potential hypertension. By tracking the child's weight daily, the nurse can quickly identify any significant fluid retention or loss, which is vital for managing the child's condition and determining the effectiveness of treatment.

Weight monitoring is a straightforward and sensitive method to assess changes in fluid balance, and it allows for timely interventions if the child begins to gain weight rapidly, signaling worsening fluid retention. Moreover, consistent tracking aids the healthcare team in making informed decisions regarding diuretics or adjustments in fluid intake.

Other actions, such as checking blood glucose or assessing for signs of dehydration, may not be as directly relevant to managing the complications associated with acute glomerulonephritis. High sodium intake, on the other hand, is contraindicated as it may exacerbate fluid retention and increase blood pressure, complicating the child's condition. Thus, daily weight monitoring stands out as the most appropriate nursing action in this case.
