No cellular energy is required to move substances from a high concentration to a low concentration
Passive Transport
Cellular energy is required to move substances from low concentration ot high concentration
Active Transport
The movement of particles in all directions through a solution or gas. Solutes move from area of higher concentration to an area of lower concentration, resulting in an equal distribution of solutes within the two areas
Diffusion
The movement of water from an area of lower concentration to an area of higher concentration
Osmosis
A solution of higher osmotic pressure
Pulls fluid from the cells - cells to vascular
**Hypertonic Solutions - ABOVE 375**
A solution of the same osmotic pressure
Expands the body's fluid volume WITHOUT causing a fluid shift
**Isotonic Solutions - 250-375**
A solution of lower osmotic pressure
Moves into the cell, causing them to enlarge

Major source of sodium
Diet
Sodium levels less than 135 - can occur where there is sodium loss or a water excess. Holds onto water to increase sodium. Likely to have a potassium imbalance as well
HYPOnatremia - decreased BUN , dry mucous membranes, thirsty
Symptoms of hyponatremia
Muscle Weakness

Tremor, seizures, or coma
Treatment of hyponatremia
Dietary replacement, can use enteral route, or parenteral route. Replace sodium and fluid losses as well as correcting other electrolye imbalances
Sodium levels greater than 145 Sodium excess or water loss. Causes fluid to shift from the cells to the interstitial spaces, resulting in cellular dehydration
