Flashcards in Fluid-Electrolyte Balance Deck (9):
1

What are three causes of a fluid-electrolyte imbalance?

Dehydration, edema, and third spacing

2

What happens during dehydration?

There is a decrease in interstitial and intravascular fluids, volume deficit

3

What are causes of dehydration?

Inadequate intake, loss of fluid to a third space, increased skin, renal or GI loss

4

Describe edema

Fluid build-up in interstitial spaces from movement of fluid out of intravascular spaces

5

When can edema be life threatening?

When it occurs in the lungs or the brain

6

What are causes of edema?

Increased capillary hydrostatic pressure (push pressure), decreased osmotic pressure (pull pressure), increased capillary permeability, or lymph flow obstruction

7

Describe third spacing

Fluid accumulation in any space other than interstitial, intercellular or intravascular spaces

8

What is the pathway fluid follows as it flows from blood vessel to the cell?

BV to interstitial to intracellular

9

What is fluid?

Water and electrolytes
