2
Q
What is hyponatremia?
A
low Na+ in the blood
3
Q
Name 2 water loving molecules related to fluid and electrolytes
A
- sodium and albumin, aka salt and protein
4
Q
What is hypervolemia?
A
- volume excess
5
Q
What is hypovolemia?
A
volume deficit (in the blood)
6
Q
Where does hyper/hypovolemia first occur and eventually finish? (3)
A
- first in the vessels/blood
- then in the interstitial fluid
- eventually in the cells
7
Q
Which molecules are osmotically active and influence the movement of water between compartments? (3)
A
- Na+, protein, and glucose
- osmotic pressure
8
Q
What does increased fluid volume pressure in one compartment do to another? (2)
A
- it may force fluid into another compartment
- Hydrostatic pressure
9
Q
What is first spacing for fluids?
A
- normal ICF and ECF
10
Q
What is second spacing? (2)
A
- edema in tissue
- too much in IF, may cause too much in ICF
11
Q
What is third spacing? (4)
A
- accumulates in the body spaces
- “potential spaces”
- ascites in abdominal cavity, pleural effusion in pleural space, blisters, etc.
- not able to move it back into the plasma

What is edema?
A
fluid surrounding our tissues
13
