A 16-year-old patient with acute glomerulonephritis complains of boredom with bed rest and asks when he can become more active. He asks, "What has to happen for me to get off of bed rest?" What is the most accurate statement by the nurse?

Choice D rationale In acute glomerulonephritis, bed rest is primarily indicated during the acute phase when hypertension and gross hematuria are present. High blood pressure is a common and serious complication due to fluid retention and renin-angiotensin system activation. A decrease in blood pressure toward normal levels indicates that the inflammatory process is subsiding and the kidneys are better managing fluid balance. Once blood pressure and urinary output stabilize, the patient can gradually increase their activity levels. Choice A rationale Acute glomerulonephritis is often a post-infectious immune response, commonly following a streptococcal infection. While antibiotics may be given to ensure the original bacteria are eradicated, the glomerular damage itself is an inflammatory, non-infectious process. Therefore, completing an antibiotic protocol is not the primary physiological indicator used to determine when a patient is stable enough to resume physical activity. The focus remains on resolving the secondary effects like hypertension and edema. Choice B rationale While monitoring electrolytes is important in any renal condition, potassium levels are not the standard benchmark for ending bed rest in glomerulonephritis. Normal potassium levels are 3.5 to 5.0 mEq/L. While hyperkalemia can occur if renal function is severely impaired, the clinical decision to allow activity is more closely tied to the resolution of gross hematuria and the stabilization of blood pressure, which reflect the recovery of the glomerular filtration barrier. Choice C rationale Dialysis is only required in severe cases of acute renal failure where the kidneys cannot maintain homeostasis despite medical management. Most cases of acute glomerulonephritis, especially in adolescents, resolve with supportive care and do not require dialysis. Telling a patient that bed rest ends when dialysis starts is inaccurate and potentially frightening, as dialysis is a treatment for failure rather than a milestone for increasing activity in a recovering patient.
