Changes in sodium, water, and protein can lead to which issues?

• A. Edema
• B. Dehydration
• C. Edema and fluid deficit problems
• D. Increased protein synthesis

Answer: (C)

Fluid balance hinges on how sodium, water, and protein shape where fluid sits in the body and how concentrated it is. Sodium sets extracellular fluid volume, with water following to maintain osmolality. Proteins in the blood, especially albumin, generate oncotic pressure that helps hold fluid inside the vessels. When these relationships are disrupted, fluid can shift into the interstitial spaces, causing edema, or be lost from the circulation altogether, leading to dehydration and reduced circulating volume. Because changes in these three factors can produce either fluid buildup in tissues or fluid deficit in the bloodstream (or both in different compartments), the situation is best described as edema and fluid deficit problems.
