The nurse is explaining how to a client how fluid and electrolytes get from one body compartment to another. Characteristics of transport mechanisms include:
1. Osmosis is the passage of water from an area of higher concentration to an area of lower concentration
2. Diffusion occurs when molecules move across a semipermeable membrane from an area of higher solute concentration to an area of lower solute concentration
3. Filtration is the process by which water and solutes move across capillary membranes pushed by osmotic pressure
4. ATP enables the movement of magnesium and potassium ions across cell membranes
2
Rationale: Osmosis is the passage of water from an area of higher solute concentration and out of an area of lower solute concentration
