While the nurse is explaining the functioning of the urinary system, the client asks the nurse, How much urine has to be in the bladder before I feel the urge to urinate? The nurse's most accurate response is:

1. At least 500 mL.
2. Around 1 liter.
3. 250-450 mL.
4. About 750 mL.

Question 2

The nurse is explaining 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.
