WEEK 5 : Mixture questions ( textbook & slides) Flashcards
Define the terms :
Solute
Solvent
Filtration
Hydrostatic Pressure
Diffusion
particles dissolved in the solvent of body fluids ( e.g salt or sugar)
the water portion of the body fluids ( water, fluids, etc)
is the movement of fluid through a cell or blood vessel membrane because of hydrostatic pressure
is the pressure exerted by water molecule against the surfaces
movement of particles ( solute) across a permeable membrane from an area of higher particle concentration to an area of lower particle concentration
True or false. Changes in either the amount of water or the amount of electrolytes in various of body fluids compartments can reduce the function of all cells, tissues, and organs
true
The interstitial and ICD volumes would drink, and the plasma volume would expand.
hypertonic
the interstitial and ICF fluid volumes would expand, and the plasma volume would shrink.
hypotonic
what acts together at the capillary membrane to maintain both ECF and ICF volumes within their normal range?
osmosis and filtration
What responses does the nurse expect as a result of infusing 500 mL liters of a 3% saline intravenous solution into a client over a 1-hour time period?
A. Plasma volume osmolarity increases; blood pressure increases
B. Plasma volume osmolarity decreases; blood pressure increases
C. Plasma volume osmolarity increases; blood pressure decreases
D. Plasma volume osmolarity decreases; blood pressure decreases
A
3% saline is = hypertonic therefore the osmolality increases ( concetration) and the blood pressure increases with that
true or false. Body fluids are constantly filtered and replaces as fluid balance is maintained through intake and output
true
Fluid intake is regulated through _____
What is the most important and the most sensitive water loss route because it is regulated and adjustable?
thirst drive
kidney
Secreted by the adrenal cortex whenever sodium levels in the ECF are low
aldosterone
what is aldosterone?
secreted by the adrenal cortex whenever sodium levels in the ECF are low
True or false. Aldosterone action increases blood osmolarity and blood volume in which promotes kidney potassium excretion.
true
this responds to changes in blood osmolarity, retains just water, indirectly regulates electrolyte retention or excretion
ADH
Fill in the blanks :
When there are low plasma sodium levels in the blood, a hormone called ____ acts on the kidney nephrons, making them more ____ to water. This allows more water to be _____ by the kidney tubules and returned to the _____, which makes the blood more diluted and decreases it osmolarity.
ADH, permeable, reabsorbed, blood.
what is nautretic peptides
the heart produces hormones, in response to increased blood volume and pressure. Inhibit the reabsorption of sodium in the kidneys and increase urine output.
Fluid Shift:
How is hydrostatic
pressure ?
it is created by the heart, this is a water pressure by the wall extend from our heart pushing in into the membrane of our walls, more water the higher the hydropressure is going to be
