Q

-reflect location where embolism lodges
-pain proximal to IV insertion site
-shortness of breath, cyanosis, tachycardia
-other signs of shock
These can cause what systemic reaction to IV therapy?

A

IV Catheter Embolism

Study Tip: causes a clot in the blood vessel which is why tachycardia results to try to mechanically push the clot. Cyanosis occurs due to decreased oxygenation r/t the clot. SOB occurs as well because an embolism is a blood clot that floats freely in the blood stream. The blood clot can travel to the lungs, where they can cause difficultly breathing.

Q

-can cause cell to rupture, hemolysis
-this is a risk when using this solution
These examples describes what type of IV solution?

A

Hypotonic Solution

Study Tip: when you put a hypotonic solution in blood which is isotonic you dilute the blood which leaves the interstitial and cells with a higher concentration of Solutes. This pulls the excess fluid into of the cells causing them to swell and burst or rupture.

Q

*isotonic in bag
*dextrose metabolizes quickly
-leaves only water (hypotonic)
These examples describes what type of IV solution?

A

D5W

Study Tip: The solution is isotonic in the bag because of the dextrose but the sugar (dextrose) metabolizes rapidly in the blood stream which leaves only water (NS) when it gets administered which causes the blood to become hypotonic almost immediately. So D5W is actually HYPOTONIC.

Q

This should be implemented to prevent what systemic reaction to IV therapy?

A

IV Catheter Embolism

55
Q

*0.9% sodium chloride (308 mOsm/L)
*Lactated Ringer’s (273 mOsm/L)
These examples describes what type of IV solution?

A

Isotonic Solution

Study Tip: These are considered isotonic solutions because the osmolality is between 200-350 mOsm/L which is the same as blood.

56
Q

-pulls fluid into vascular space
-use if client is dehydrated
These examples describes what type of IV solution?

A

Hypertonic Solution

Study Tip:
Hypertonic solutions have a high concentration of Solutes so when placed into the blood which is isotonic it increases the concentration of Solutes in the blood stream to be a higher concentration than in the interstitial and cells. This pulls fluid from the interstitial and the cells into the blood vessel or intravascular space. This treats dehydration by increasing blood volume.
