Unit IV COPY Flashcards
(90 cards)
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
