1

reasons for IV therapy

-maintain daily fluid/electrolyte balance
-replace build.electrolyte losses
-correct fluid/electrolyte imbalance
-provide access to venous system for med administration

2

Iv solution that is used to maintain normal blood plasma

-dextrose(sugar) or saline (salt) diluted in water for injection (solvent)

3

osmolarity

-concentration of solution expressed as total number of solute particles per liter

4

how is blood concentration describes

-millOsmols per Liter

5

how are IV solutions classified

-isotonic: same osmolarity as blood
-hypotonic: lower osmolarity than blood
-hypertonic: higher osmolarity than blood

6

what is normal blood osmolarity

280-320 mOsm/L

7

reasons why medication are given through IV therapy

-absorption into blood stream is immediate
-

8

peripheral IV: facts

-most common type of IV
-short term therapy
-goes into superficial views of the hand and forearm
-Iv fluid, medication, blood products instilled

9

pump infusion

given with control using automated pump that can calculate the amount of time and rate you would like to administer medication

10

gravity infusion

usually given over longer period of time
-less exact than automate pump
relied on nurse to make sure its set properly

11

what to do why IV order

-check most recent/current order
-renewed every 24hrs at minimum

12

parts of a correct IV order

-written by legally authorized HCP
-date and time order was written
-signature of authorized HCP
-type of solution and/or additive
-amount of solution to be given (volume)
-over what time or rate of continuous infusion

13

parts of solution bag

-port: tubing insertion and additives

14

parts of tubing

-spike
-drip chamber
-backflow check valve
-port
-clamps: roller regulate flow and slide stop flow
-luer lock
-end interred into IVAD/catheter hub

15

types of peripheral IV catheter needles

-over the needle catheters
-winged catheter (butterfly)
-OSHA mandated safety needles

16

winged catheter

-reduced risk of contamination
-improves stability
-excellent with difficult views

17

OSHA mandated safety needles

-active: user activated
-passive: automatic retraction

18

universal color codes gauges

- magma(14): trauma
-gray (16) major surgery, volume volume infusions, unstable patients
-greem(18): love volume infusions, multiple/rapid transfusions
-pink (20): medications, hydration, transfusion
-blue (22): small view, common for short term access, and usually can't administer blood
-yellow (24): fragile small veins, pedi population, last resort for adults

19

primary lines

-continous primary infusion
-bolus of fluid
-may have intermittent secondary infusions
-pump or gravity infusion
additives are run slowly

20

how is potassium delivered

-dangerous to run quickly
-runs slow

21

intermittent Venous Access devices (saline locks)

- for intermittent infusion
-extension of tubing
-flushing
-usually used of IV antibiotics and noncontiguous meds

22

why do IVAD have extension tubing

-infection control

23

flushing guidelines

-2-3mL saline q 12hrs with use
-pulsatile method
-positive pressure method

24

what is the positive pressure method?

-hold fluid pressure on the IV and doesn't allow for back flow of blood or fluids

25

peripheral site selection considerations

-choose smallest gauge: view must support gauge
-PIV not for: total parenteral nutrition (TPN), pH less than 5 or greater than 9 and osmolarity greater than 6000 mOsm/L
-upper vs lower extremities
-duration of therapy
-limb
-start as distal as possible
areas to avoid
-contraindications
-no used for routine blood draws
-site selection in children

26

when to use upper vs lower extremities for PIV?

adults: upper extremities not lower
-pediatics: can do scalp and lower extremeties

27

contraindications for peripheral site selection

-mastectomy
-arm with lymph node dissection
-arm wi artery venous fistula

28

why do distal in periperhal site selection

if vein blows, you have sites further up

29

what are areas to avoid in peripheral site selection

-ventral surface and lateral surface of wrist for 4-5 inches: nerve damage
-burns, infections in extremity
-AV fistula/ catheters for dialysis

30

why not use legs in as peripheral access in adults

-stagnation of circulation causes risk of thromboembolism
