A school-aged child with acute glomerulonephritis (AGN) has a blood-pressure 136/90 mm Hg, oliguria, and periorbital edema. Which intervention is the nurse's priority?

A. Encourage oral fluids to maintain hydration: Increasing fluid intake is not appropriate in AGN with oliguria and edema. Extra fluids can worsen hypertension and fluid overload, increasing the risk of pulmonary edema. B. Elevate the head of the bed to ease breathing due to pulmonary edema: The child’s hypertension, edema, and oliguria suggest fluid overload, which can lead to pulmonary congestion. Elevating the head of the bed improves lung expansion and oxygenation. C. Restrict sodium intake as ordered: Sodium restriction is important for managing hypertension and edema in AGN. However, it is a long-term intervention and not the first priority when the child is at risk for acute respiratory distress. D. Monitor daily weight at the same time each day to assess for fluid retention: Daily weights are essential for monitoring fluid status. However, this is a routine measure and not the priority in the acute setting where breathing difficulty must be addressed first.
