NUR 347 Quiz 21. Intracellular (ICF)
Answer
About 70% of body water
2. Extracellular (ECF)
Answer
- 30% of body water
- Includes intravascular (plasma) & interstitial (third space)
3. Fluid balance =
Answer
Shifting
- Shifting preformed by body organs and body systems
4. Four processes for shifting of body fluids
Answer
1. Osmosis
2. Diffusion
3. Active Transport
4. Capillary filtration
,5. Osmosis
Answer
passage of solvent through a SEMIPERMEABLE membrane from an area of LOWER
concentration to an area of HIGHER concentration
6. Diffusion
Answer
tendency of solute to move freely throughout a solvent from an area of HIGHER concentration
to an area of LOWER concentration
7. Active transport
Answer
- Process that requires energy for the movement of substances through a cell membrane, against
the concentration gradient, from an area of LESSER solute concentration to an area of
HIGHER solute concentration
- Adenosine triphosphate (ATP), which is stored in all cells, supplies energy for solute movement
in and out of the cell.
8. Capillary Filtration
Answer
-Filtration is the passage of fluid through a PERMEABLE membrane
-Fluids move from an area of high pressure to one of lower pressure.
- Capillary filtration results from the force of blood "pushing" against the walls of the
capillaries.
-At the arterial end of the capillaries, filtration is dependent primarily on arterial blood pressure
- At the venular side of the capillaries, filtration is dependent on venous blood pressure
- The "pushing" force is referred to as hydrostatic pressure
, 9. Semi-permeable
Answer
allows fluids and some particles to pass (s=s)
10. Permeable
Answer
allows fluids and all particles to pass (p=p)
11. Hypovolemia
Answer
- Fluid volume deficit (FVD) is caused by a loss of both water and solutes in the same proportion
from the ECF space
- Dec. ECF, Dec. circulating blood volume
12. Cause of Hypovolemia
Answer
-Dec. intake (oral trauma, NPO, impaired thirst)
- Inc. output (v/d, kidney disease, gastric suction)
-Interstitial space/third spacing
13. Hypervolemia
Answer
- Fluid volume excess
