A client with glomerulonephritis is prescribed strict bedrest. Which explanation best supports this prescription?

• A. Prevents injury
• B. Promotes rest
• C. Promotes diuresis
• D. Stimulates RBC production

Answer: (C)

In glomerulonephritis, the aim is to reduce the kidneys’ workload and give inflamed glomeruli a chance to heal. Strict bedrest helps by limiting physical stress and stabilizing blood pressure and kidney perfusion. With less stress on the kidneys, inflammation subsides and renal function begins to recover, which is often seen as an increase in urine output. That rise in urine production—diuresis—signals that the kidneys are clearing excess fluid and moving toward recovery.

So, the best explanation is that bedrest supports the healing process in the kidneys, and as this healing occurs, diuresis can occur as the body eliminates accumulated fluid. Rest reduces exertion-related stress on the kidneys, making it easier for diuresis to occur, whereas other options aren’t the primary mechanism at play here.
