Advanced Skills Theory Flashcards
1
Q
Hypertonic solutions
A
higher solute in the solution causes water to leave the cell
2
Q
Isotonic solution
A
equal inside and outside the cell
3
Q
Hypotonic solution
A
lower solute in the solution then the cell - causes water to go into the cell (NS, LR)
4
Q
What does it mean if an IV is “positional”?
A
This means that the IV flows with pressure, but not with gravity. It is against a valve or a similar obstruction.
5
Q
What is the outer layer of veins called?
A
Tunica Adventitia
6
Q
What is the middle layer of veins called?
A
Tunica Media
7
Q
What is the inner layer of veins called?
A
Tunica Intima
8
Q
What does the tunica intima do?
A
- Promotes unidirectional blood flow toward the heart & prevents backward flow.
- Endothelial lining forms the valves.
9
Q
What does the tunica media do?
A
- Less developed
- Location of nerve endings, elastic type tissue
- Weaker muscle coat, can collapse when blood pressure falls
10
Q
What does the tunic adventitia do?
A
- Thinner, less elastic type properties
- Superficial – does not pulsate
11

A
__ mg/1ml
12
Q
Serial Dilution
A
1g/__ ml
