Fluids and Electrolytes Flashcards
1
Q
Fluid volume excess:
A
Hypervolemia
2
Q
What is hypervolemia?
A
Too much fluid in the vascular space
3
Q
What causes hypervolemia?
A
- Heart failure
- kidney failure (kidneys aren’t working)
- alka seltzer, fleet enema, IVF w/NA (all 3 have a lot of sodium)

5
Q
Sodium makes the body do what?
A
retain water
6
Q
Where is aldosterone found??
A
Adrenal glands
7

A
When blood volume gets low (vomiting, blood loss, etc) aldosterone secretion increases retain NA/water, blood volume goes up
8
Q
Disease with too much aldosterone:
retain too much sodium and water= fluid volume excess
A
Cushings and Hyperaldosteronism (Conn’s)
9
Q
Diseases with too little aldosterone:
loss of sodium and water=fluid volume deficit
A
Addison’s disease
