Which finding is commonly observed due to fluid overload in the oliguric phase?

• A. Edema
• B. Hypernatremia
• C. Hypotension
• D. Weight loss

Answer: (A)

Fluid overload in the oliguric phase happens because the kidneys aren’t producing much urine, so water and sodium aren’t being eliminated. The resulting fluid retention increases the volume in the bloodstream and tissue fluid, leading to edema—the swelling from excess fluid in tissues. Weight gain is a common companion because the body stores the extra fluid. Hyponatremia and hypotension are less typical in this scenario, since the problem is excess fluid rather than fluid loss, and edema best reflects the fluid overload.
