IV Fundamentals Flashcards
What is the main goal of IV therapy? And what is it used for?
Maintain & regain fluid electrolyte balance
And
Medium for delivery of meds
-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?
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.
3% sodium chloride
10% dextrose in water
These examples describes what type of IV solution?
Hypertonic Solution
Osmolarity:
1030 mOsm/L
(500 mOsm/L)
Consists of electrolytes, Na+, Cl-, K+, Ca and lactate.
Lactated Ringer’s
Study Tip: the liver metabolizes lactate to form bicarbonate to help correct acidosis
-can cause cell to rupture, hemolysis
-this is a risk when using this solution
These examples describes what type of IV solution?
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.
-Shortness of breath
-intake greater than output
-Increase Bp, pulse, respiratory rate
-Crackles in lungs on auscultation
-Extremity edema
This assessment shows that your patient has what systemic reaction to IV therapy?
Fluid Overload/Circulatory Overload
dextrose 5% & 0.45% sodium chloride
What is this IV solution called?
D5 ½ NS
0.45% NaCl
D5W IV
These examples describes what type of IV solution?
Hypotonic Solution
Osmolarity;
154 mOsm/L
D5W is Isotonic in the IV bag and Hypotonic in the Bloodstream
-mechanical: excessively large IV catheter
-chemical: infusion of irritating solutions
-bacterial
These can cause what local reaction to IV therapy?
Phlebitis
Study Tip:
Phlebitis is often caused by an traumatic injury to a vein such as too large gauge of needle being used on too small of a blood vessel.
Phlebitis can also result from certain medications (ex. K+) that can irritate the veins.
Vesicant medication leaks outside infiltrated IV
These can cause what local reaction to IV therapy?
Extravasation
How do you calculate drip rates for Manual IV’s?
Volume (mL) x drop factor (gtt/mL) / Time (min) = IV flow rate gtt/min
0.9% sodium chloride
Lactated Ringer’s
These examples describes what type of IV solution?
Isotonic Solution
Osmolarity:
308 mOsm/L
(273 mOsm/L)
What are the four standard drop factors?
- 10 gtt/mL: macrodrop
- 15 gtt/mL: macrodrop
- 20 gtt/mL: macrodrop
- 60 gtt/mL: microdrop
What are 3 common localized reactions to using IV therapy?
Phlebitis (mechanical, chemical, bacterial)
Infiltration
Extravasation
0.45% sodium chloride
What is this IV solution called?
½ normal saline
Varying tissue damage, pallor, swelling, pain
This assessment shows that your patient has what local reaction to IV therapy?
Extravasation
-osmolarity greater than 350 mOsm/L
-if osmolarity is greater than 500, administer through central lines
These examples describes what type of IV solution?
Hypertonic Solution
When administering an intermittent IV Bolus
*IV piggyback is usually dosed at _______ compared to the ______ primary solution.
50-250 mL
500-1000 mL
-IV meds administered too quickly
-Toxic effects related to med being infused
These can cause what systemic reaction to IV therapy?
Speed Shock
Facility policy/can leave in for treatment of meds
Antidote medication
This treatment is used for what local reaction to IV therapy?
Extravasation
Use caution if client is at risk for fluid volume overload.
This example describes what type of IV solution?
Hypertonic Solution
0.9% NaCl
0.9% sodium chloride
Preferred solution when administering blood products to prevent hemolysis of RBC’s
This is what commonly used IV solution?
NS (Normal Saline)
-Lightheadedness
-Chest pain/discomfort, palpitations, rapid pulse
-shock, cardiac arrest
This assessment shows that your patient has what systemic reaction to IV therapy?
Speed Shock
*isotonic in bag
*dextrose metabolizes quickly
-leaves only water (hypotonic)
These examples describes what type of IV solution?
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.
