WEEK 5 : Mixture questions ( textbook & slides) Flashcards

1
Q

Define the terms :
Solute
Solvent
Filtration
Hydrostatic Pressure
Diffusion

A

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

Q

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

A

3% saline is = hypertonic therefore the osmolality increases ( concetration) and the blood pressure increases with that

Q

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.

A

ADH, permeable, reabsorbed, blood.

Q

what is nautretic peptides

A

the heart produces hormones, in response to increased blood volume and pressure. Inhibit the reabsorption of sodium in the kidneys and increase urine output.

Q

Fluid Shift:
How is hydrostatic
pressure ?

A

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

Q

Fluid shift:

What is oncotic pressure?

A

oncotic is made by the albumin, we have to HAVE proteins in order to have pressure, and come back to us.

Pull that back in and go back to the heart and do the cycle all again.

17
Q

Name the categories of regulation of water balance

A

Hypothalamus Pituitary Gland
GI
Genitourinary
insensible water loss

18
Q

Can potassium be administered via IM or subcutaneous injection?

A

no, severe tissue irritant

19
Q

true or false: potassium movement into the cell is enhanced by insulin

A

true
