Unit IV COPY Flashcards
Administration of fluids, blood components and/or medication into a vein
Intravenous
Include electrolyte solutions, vitamins, nutrient preparations and commercial blood “fractions” designed to be administered into a vein
Intravenous fluids
Solutions containing protein or starch molecules that remain uniformly distributed in fluid (do not dissolve) fail to form. True solution
Colloid
Non-colloid (salts), electrolyte solution
Crystalloid
The insertion of a needle or catheter into a vein
Vein puncture
Extremities, vs. use of central vein
Peripheral IV therapy
Catheter inserted into a centrally located vein unusually subclavian or jugular
Central venous catheter or central line (CVC)
Entry into the vascular system via the insertion of a catheter into a peripheral vein threaded through to the superior vena cava
Peripherally inserted central catheter (PICC)
Surgically placed under skin and accesses vascular system internally
Implanted ports
catheters, cannulas, or infustion ports usually disned for long term repeated access to the vasculr system
vascular access device (VAD)
by route other than GI into tissue
parenteral
nutrionally adequate hypertonic solution, usually given via CVC
total parental nutrition (TPN)
vesicant solution is administered into surrounding tissue, vesicants are solutions capable of causing tissue injury or destruction if they escape into surrounding tissue
Extravasation
tissue is destroyed
nonvesicant soultion is administered into surrounding tissue
infiltration
tissue is not destroyed
symptoms occur 48 hours or more after the Rx was given
delayed extravasation

what is the main purpose of IV therapy
hydration
who can order an IV
MD, PA, NP
2/3 of body fluids, has the most protein in it, located in the cells, having protein helps keep fluid in cells
intracellular fluids (ICF)
1/3 of bldy fluids, found outside of cell
extracellualr fluids
what are the 4 components of extracellualr fluid
intravascular
interstitial
transcellular
lymph
plasma space that is in the vessels, 2nd highest protein component
intravascular
fluid between cells
interstital
ceribral spinal space, GI tract, plural space are all considered what kind of fluid
transcelluar fluid
tissue fluid, mostly water but also has albumin, salt, ureia, glucose
lymph
movement of water across cell membranes from the less concentrated solution to the more concentrated solution
osmosis
body looses water ad electrolytes from the extracellular fluid
fluid volume deficit
fluid is colleced in certain areas
third space syndrome
fluid loss
hypovolemia
body retains water and sodium equally
fluid volume excess
increase in fluid volume (blood volume)
hypervolemia
intravascular and intersitial (legs & feet)
edema
have decreased protein levels
loose water, have excess sodium, water is drawn into the vascular compartment from the interstitial space
dehydration
too much water, not enough sodium
overhydration
has the same osmotic pressure as the cell, they can incresase extracellular fluid volume
isotonic
