Q

Starting an IV Site

A
  • Start distally

Q

Why do you want to start an IV distally and work your way up?

A

You can move up if vein does not work

- If you start higher, you can’t go down down due to leaky veins

Q

Normal Saline Lock

A
  • Is out connection/ access; how we can administer drugs
  • Need to clean saline lock with alcohol swap for 15 seconds before administrating anything
  • Need to flush the saline lock with saline every 24 hours or before giving medications
  • Should feel no resistance
  • Patient should feel no pain and no swelling

Q

Why do you flush saline within the saline lock every 24 hours?

A
  • Too make sure that the IV is still in the vein
  • ## Too ensure there are no kinks

Q

Documenting your IV Start

A
  • The size of needle gauge you used
  • Location
  • Patient tolerance
  • How you secured it
  • How many attempts it took if first time was unsuccessful
  • What you administered and the amount
  • Component is CVS

Q

Extracellular Fluid

A

Fluid outside of cells
- Counts for 32% of fluid

a. Intravascular fluid: Fluid in the blood vessels (8%)
b. Interstitial fluid: Fluid between the blood vessels (24%)

17
Q

Transcellular Fluid

A

Aqueous humor, CSF, and CVS

- Counts for 1% of fluid

18
Q

Cellular Plasma Membranes: Barrier

A

Conditions inside are different than outside

19
Q

Cellular Plasma Membranes: Permeability

A

Cells are selectively permeable Selective

20
Q

Cellular Plasma Membranes: Selective Permeable

A

Permits free passage of some material and restricts others

21
Q

Cellular Plasma Membranes: Passive Process

A

No energy expenditure by cell

22
Q

Cellular Plasma Membranes: Active Process

A

Energy expenditure by the cell

23
Q

Osmolality

A

Total solute concentration in an aqueous solution

- The concentration of molecules/ ions in a liquid solution inside the body

24
Q

Tonicity

A

Cells affected by the osmolality of fluid around them

25
What are the three types of tonicity?
1. Isotonic solution 2. Hypertonic solution 3. Hypotonic solution
26
Isotonic Solution
Two solutions having the same osmotic pressure across a semipermeable membrane. This state allows for the free movement of water across the membrane without changing the concentration of solutes on either side - Cell stays the same
27
Hypotonic Solution
The concentration of solutes is greater inside the cell than outside of it - The cell will expand
28
Hypertonic Solution
The concentration of solutes is greater outside the cell than inside it. Fluid will leave the cell and go into interstitial space - The Cell will shrink
29
What will happen to the cells if the solution is isotonic?
The cell will stay the same size
30
What will happen to the cells if the solution is hypotonic
The cell will expand/ swell
31
What will happen to the cells if the solution is hypertonic?
The cell will shrink
32
Fluid IV and Electrolyte Replacement: Isotonic
- 0.9 NS - D5W - LR
33
Fluid IV and Electrolyte Replacement: Hypertonic
- D5NS | - D5 1/2 NS
34
Fluid IV and Electrolyte Replacement: Hypotonic
- 0.45% NS
35
How do you know if you inserted the needle catheter in a vein?
Will have flash back | - Blood will fill up
