Albumin level greater than 4 can cause which condition?

• A. Hyperkalemia
• B. Metabolic acidosis
• C. Third spacing
• D. Dehydration

Answer: (C)

Fluid distribution between the intravascular space and the interstitial (third) space is governed mainly by plasma oncotic pressure, largely created by albumin. When albumin levels are high, oncotic pressure in the blood is elevated, which tends to pull and retain more fluid inside the vessels rather than letting it leak into the interstitial space. Third spacing—the accumulation of fluid in nonfunctional interstitial spaces—typically occurs when plasma oncotic pressure falls (due to low albumin) or when capillary permeability increases. So higher-than-normal albumin would generally resist third spacing rather than cause it. The other options aren’t direct effects of albumin level: potassium balance (hyperkalemia) is not set by albumin concentration; metabolic acidosis is a bicarbonate/acid-base issue rather than a direct consequence of albumin level; dehydration relates to overall body water and intake/status rather than being caused by high albumin. In clinical practice, third spacing is more commonly tied to hypoalbuminemia or increased capillary leak, not to elevated albumin.
