Term
What is IV Therapy?
Definition
Method used to administer fluids elecyrolytes and medications directly into the blood stream.
Term
Why Use the IV Route?
Definition
a. Treat fluid and electrolyte imbalance
b. Administer medications
c. Deliver blood products
d. Dilute Iritating drugs
e. Orders for IV therapy (how are the orders written?)
Term
Advantages of the IV Route
Definition
a. Give medications rapidly
b. Administer fluids rapidly
c. Rapid onset and rapid action
d. Bypasses GI tract and therefore unaffected by GI
e. GREAT for medications which would otherwise irritate GI
f. When client is NPO, can still receive medications and fluids
g. THE GOAL IS TO REACH BALANCE IN THE BODY. The vascular system to be balanced with the extracellular fluid. Hypertonic, hypotonic, isotonic solutions.
Term
Disadvantages of the IV Route
Definition
a. Once administered, there is no getting the medication back.
b. Requires considerable degree of skill to initiate and maintain
c. Iv related complications may occur
i. Phlebitis, sepsis, infection, allergies
d. There is [pain and/or discomfort associated with procedure
Term
What are some incompatibilities of IV Therapy?
Definition
i. Solutions
ii. Drugs
iii. PCA meds
iv. ALLERGIES!!!!!
v. see a list of medications and common fluids used to administer/infuse that location
Term
what are the Types of Primary Solutions?
Definition
a. Isotonic
b. Hypotonic – less sodium than blood and therefore water will cross from solution into blood
c. Hypertonic
Term
What is Isotonic solution?
Definition
having the same concentration of solutes as the blood (esp sodium)
Term
what is the benefits of Isotonic Solutions?
Definition
i. Cells don’t shrink or swell
ii. Maintains balance because the amount of solute v solution ratios are equal. Therefore no fluid moves across membranes or the net change is zero. There is no pull of fluid in or out of the vascular space
iii. Given for bleeding, hypovolumia, etc after surgery
Term
What are the most common types of Isotonic Solutions?
Definition
1. NS – Normal Saline (0.9% NaCl)
2. LR – Lactated Ringer
3. D5W – 5% dextrose in water
Term
What is a hypotonic Solution?
Definition
DRAWS WATER FROM CIRCULATION to CELLS
Term
What are the benefit of Hypotonic solutions?
Definition
i. Cells Grow
ii. Free water moves from circulation (blood and IV) INTO cells to hydrate
iii. Used to treat cellular dhydration
Term
What are the most common types of Hypotonic Solutions
Definition
iv. 0,45% NaCl (1/2 Normal Saline)
v. 0.33% NaCl (1.3 Normal Saline)
vi. 0.225% NaCl (1/4 Normal Saline)
Term
What is an Hypertonic Solution?
Definition
DRAWS WATER FROM CELLS to Circulation (blood+IV)
Term
What are the benfits of Hypertonic Solution?
Definition
i. Cells Shrink
ii. Draws fluid out of the intracellular and interstitial compartments to the vascular compartments
iii. *NOT for clients with kidney or heart disease
iv. *NOT for clients who are dehydrated
Term
What are the most common types of Hypertonic solutions
Definition
v. D5 normal saline
vi. D5 half saline
vii. Colloids
Term
what is colloids?
Definition
1. Plasma expanders – cause cell to expand. Small particles that cross the membrane and swell it in order to allow movement of cell out of
Term
WHat is TPN?
Definition
Total Parental Nutrition

1. Very high osmalarity so must go through a more significant portal of entry.
2. Can be infused indefinitely into centravenous access device: IJ, pic lines, Ports, etc
3. Lots of sugar – glucose
Term
what are Crystalloids?
Definition
i. Water
ii. Electrolytes
iii. Most of the common IV solutions – particles are small enough to cross the semipermeable membrane
iv. Sometimes form crystals in the line. If this happens:
1. Stop IV, remove line, clean line. DO NOT want to infuse this into patient.
Term
what are some plasma expanders?
Definition
1. Albumin
a. Hetastarch (Hespan)
2. Blood or blood products
a. Whole blood
b. Paced RBC
3. Too large to cross the permeate the membrane
Term
what is colloidal solutions?
Definition
i. Plasma expanders
1. Albumin
a. Hetastarch (Hespan)
2. Blood or blood products
a. Whole blood
b. Paced RBC
3. Too large to cross the permeate the membrane
Term
what is the FIRST thing to have before starting an IV?
Definition
Doctors order.
Term
what should the Dr's order include?
Definition
i. Type of solution
ii. Medications / additives (potassium)
iii. Volume to be administered
iv. Time period for infusion or rate
Term
what do we assess client for BEFORE starting IV?
Definition
i. Allergies: latex (gloves, tape etc), medications, cleaning solutions (betadyne (shellfish))
ii. Pertinent Labs (H&H, CBC, etc)
Term
what equipment would you need to start IV?
Definition
i. Gloves, angiocath, needle, alcohol prep, tape, dressing (e.g. tegaderm), gauze, drop set, saline flush, connector tubing, IV catheter, IV fluid, Tower, tourniquet
Term
what do you document?
Definition
site of IV, how pt tolerated
Term
what do we assess the cleint for AS we are starting the IV?
Definition
i. veins for appropriate, size, shape, thickness, etc
ii. look for tattoos, scars, damaged veins, compromise (esp in legs
iii. consider lenths of IV infusion (hours, days etc) and additives of solution when selecting sites
iv. consider occulusions, circulation, location (don’t want it in an often-moved place (like antecubital)
v. do not use arm on side of a mastectomy
vi. adult arm-veins (avoid antecubital if possible (decreases mobility and may need to be used for pic line etc)
vii. children
1. older children, forearm, avoid restricting movement
2. small infants, hand, wrist, forearm, foot, ankle, avoid foot if learning to walk, I possible scalps, etc

• A large air bubble in the arteries to the brain will cause immediate loss of consciousness and often causes convulsions (fits). It may also cause a stroke.
• An air embolism in the coronary arteries (which lead to the heart) will cause a heart attack. A heart attack can also be caused by a large air embolism in the arteries to the brain.
• An embolism in a blood vessel to the lungs (pulmonary embolism) causes chest pain and shortness of breath.
