GUARANTEED PASS
1. A gain of more water than salt is called:
*gain water: dilutional hyponatremia
2. A loss of more salt than water is called:
*lose salt: depletional hyponatremia
3. Aldosterone increases or decreases potassium excretion in
urine?: Increases
4. I have low ionized calcium levels after a massive or fast blood
transfusion or FFP because of:: citrate (preservative in blood
products) *citrate renders calcium inactive
5. PTH increases plasma calcium, therefore, pt's with
hypoparathyroidism from sx or trauma will have:: low levels of
calcium

NSG
6. With low levels of extracellular Ca, voltage gated Na channels
are less stable. Making them more likely to open up allowing
them to depolarize more easily. This makes neurons more::
excitable!
*which means tetany occurs
7. PTH increases plasma calcium, therefore, pt's with
hyperparathyroidism will have:: higher levels of calcium
8. The decreased neuromuscular excitability in hypercalcemia is
caused by:: elevation of threshold potential of excitable cells.
9. Chronic alcoholism is a major risk factor for which electrolyte
imbalance?-
: Hypomagnesemia
10. Acetylcholine causes muscles to:: contract.
11. Mg in extracellular fluid usually depresses release of
acetylcholine. Therefore if too few Mg ions are present,
muscles will:: contract
*this is due to neuromuscular excitability

12. Too much Mg, causes acetylcholine to rarely be released
causing muscular:: depression
13. Phosphate is an important component of ATP. Since ATP is a
major source of energy, if we have low phosphate we are more
likely to be:: weak 24. Pt's with hyperphosphatemia and kidney
dx are likely to have to
______________ salts in soft tissues of the body. Leading to
aching, stiffness in joints, itching, and conjunctivitis.: phosphate
25. What electrolytes are in the ECF and ICF?: ECF = K+ and
Mg ICF = Na+, Cl, Bicarb
26. What are the components of blood?: RBCs (carry O2)
platelets (clotting)
leukocytes (WBCs) (infection)
