Rationale 1: Colloids are proteins or other large molecules that stay suspended in the blood for long periods because they are too large to easily cross membranes. They draw water molecules from the cells and tissues into the blood vessels through their ability to increase plasma oncotic pressure.
Rationale 2: Normal human serum albumin (Albutein) does not act on the kidneys.
Rationale 3: Normal human serum albumin is not a concentrated saline solution.
Rationale 4: Crystalloids are intravenous (IV) solutions that contain electrolytes, not proteins, in concentrations resembling those of plasma.
Global Rationale: Colloids are proteins or other large molecules that stay suspended in the blood for long periods because they are too large to easily cross membranes. They draw water molecules from the cells and tissues into the blood vessels through their ability to increase plasma oncotic pressure. Crystalloids are intravenous (IV) solutions that contain electrolytes, not proteins, in concentrations resembling those of plasma. They are used to replace lost fluids and promote urine output. Normal human serum albumin (Albutein) does not act on the kidneys. Normal human serum albumin is not a concentrated saline solution.
