YOUR GRADES.
1. Hypokalemia cells are considered - correct answer -
hyperpolarized
2. Hyperkalemia cells are considered - correct answer -hyper
polarized
3. Hypercalcemia _________ cell perm. To ________ - correct
answer -decreases; sodium
4. Hypocalcemia ________ cell perm. To ___________ - correct
answer -increases;sodium
5. Intracellular space contains the ___________ portion of total
body water at _________ - correct answer -largest; 40%
, Page | 2
6. Why do infants have increased TBW - correct answer -they
have less adipose tissue
7. Why are infants vulnerable to changes in TBW - correct answer
-higher metabolic rate, and potential for fluid loss through their
skin due to their greater body surface
8. Measure of solute concentration in a solution - correct answer -
osmolality
9. Normal plasma osmolality - correct answer -280-295
10. Amount of pressure or force that is exerted by solute
molecules of a given compartment - correct answer -osmotic
pressure
11. The _________ the osmolality the ________ the osmotic
pressure - correct answer -higher;higher
, Page | 3
12. Force within a fluid compartment - correct answer -
hydrostatic pressure
13. Force which helps to keep water/fluid within a compartment -
correct answer -oncotic pressure
14. 3% saline - correct answer -hypertonic solution
15. What happens with 3% saline - correct answer -water moves
from within the cell to extracellular space causing swollen cells
to shrink
16. .45% - correct answer -hypotonic solution
17. What does .45% do - correct answer -cause intravascular
space to become more dilute. Water will move extracellular
space to intracellular space causing cells to swell
18. Fluids for hypernatremia - correct answer -d5 water
, Page | 4
19. .45% saline is used for - correct answer -hypertonic
extracellular swelling- cells are shriveled
20. Arterial blood volume - correct answer -amount of blood
within the arterial space which perfuses organs
21. Secreted by pituitary gland in response to water deficit,
sodium excess, or low BP - correct answer -antidiuretic
hormone
22. Where does ADH work - correct answer -kidneys reabsorb
water thus increasing plasma volume
23. Hormone secreted from the adrenal cortex and is
responsible for increased renal sodium reabsorption and
potassium excretion - correct answer -aldosterone
