Which instructions should the nurse give parents about caring for a child with acute glomerulonephritis with edema?

Choice A reason: No activity restrictions are inappropriate in acute glomerulonephritis with edema, as exertion may worsen hypertension or renal strain. Gross hematuria indicates active glomerular inflammation, requiring limited activity to reduce cardiovascular stress and promote renal healing, making unrestricted activity an incorrect instruction for managing this condition. Choice B reason: Limiting activity until gross hematuria subsides in acute glomerulonephritis reduces renal and cardiovascular stress, preventing exacerbation of hypertension or hematuria. Rest promotes glomerular healing by minimizing blood pressure spikes. This is the priority instruction, as hematuria signals active disease, requiring cautious management to prevent complications. Choice C reason: A high-potassium diet (e.g., bananas) is contraindicated in acute glomerulonephritis, as impaired renal function may cause hyperkalemia, risking arrhythmias. Low-potassium diets are often recommended. Limiting activity addresses hematuria and hypertension, making high-potassium intake an incorrect and potentially harmful instruction for this condition. Choice D reason: Bedrest for 2 weeks is excessive in acute glomerulonephritis, as most children recover with limited activity until hematuria resolves. Prolonged bedrest risks complications like thrombosis without evidence of benefit. Limiting activity based on hematuria is more targeted, making fixed bedrest an incorrect and overly restrictive instruction.
