IV Therapies and Central Lines Flashcards
What are the purposes of establishing an IV?
- Helps maintain or restore the fluid volume and electrolyte balance of the body.
- Provide a way to nourish and feed a patient calories.
- A way to give needed medication (both routine and emergent) – such as pain meds
- To transfuse blood products.
- To provide avenue for diagnostic lab testing.
Do RNs need orders for IVs? What other instances would RNs need orders?
Yes, also for saline lock, blood draws, and IV removal; check orders prior do doing any action mentioned.
What are some occupational risks related to IV therapy?
- Needlesticks
- Chemical exposure
- Latex allergy
- Biological hazards
How might you prevent occupational hazards?
- Facility practice policies
- Personal protective equipment
- Vaccinations
- Training
- Hand washing
- Safer equipment
What are some things that might cause someone allergies?
Drugs, iodine, tape/adhesive, and latex (i.e., tourniquets, bp cuffs, vials, gloves, injection caps, tubing)
What is a 14G catheter used for and what color is it?
Orange and massive traumas.
What is a 16G catheter used for and what color is it?
Gray; trauma, surgery, multiple larger volume transfusions
What is an 18G catheter used for? What color?
Green; blood transfusions and large fluid volume of fluids
What is a 20G catheter used for? What color?
Pink; multi-purpose, medication, hydration, routine therapy.
What is a 22G catheter used for? What color?
Blue; chemotherapy infusions, patients with small veins, elderly, peds
What is a 24G catheter used for? What color?
Yellow; very fragile veins and elderly patients.
How do you find the vein before starting a peripheral IV?
(First step) Go by “feel” and not by site, lay arm hang downward, avid areas of joint flexion, start distally and work upward.
Would you start an IV in extremities with same side mastectomy?
No because this can cause lymphedema and high risk infections.
True or false: it is safe to start an IV in any extremity that has dialysis shunts or AV fistulas.
False
True or false: I would not start an IV where there are present signs and symptoms of infection
True
True or false: I would not start an IV in areas with extensive scarring, burns, or surgeries.
True
True or false: I would start an IV on CVA paralysis side
False
True or false: I would not start an IV in extremities that have previous recent infiltration, extravasation, phlebitis.
True
True or false: I would not start an IV in a site distal to previous puncture
True
What are some procedural technical pointers for starting an IV?
(Second step); prepare equipment, tourniquet 6-8 inches above intended site, pull skin taunt, bevel up, 10-30 degree angle, insertion toward the heart, and one smooth movement.
How would you never tie a tourniquet?
In a knot
What are some alternatives to dilate the vein?
If vein is not adequately dilated, massage vein prn, clench fist prn, and use heat prn.
What is extension tubing used for?
Connects to the patients IV catheter to make a saline lock (with a cap on the end)
What are some things to document after inserting an IV?
Record the date and time of insertion, gauge, type of catheter, number of attempts, location of insertion site; if saline lock or if IVF infusion; patient tolerance.
How often should the peripheral IV (PIV) be changed?
No more frequently than 96 hours, but at least every 7 days. Consult hospital policy.
How would you maintain the peripheral IV catheter patency?
Intermittent flushing; common practice if Saline flush q 8 hours or q 4 hours.
How often would you assess the IV?
every 8 hours and prn for any abnormalities or complaints.
When would you discontinue an IV?
Upon provider order or discharge OR if complications occur (then it is restarted in another area).
What would you document for PIV discontinuation?
Catheter and fluids were discontinued, appearance of site and dressing applied, whether or not the cannula was intact, condition of patient.
What is the most common cause of infiltration?
Damage to the wall during insertion or angle of placement.
When does infiltration occur?
When fluid or medications leak into the surrounding tissue - caused by improper placement of the catheter.
What are the signs and symptoms of infiltration?
Swelling, discomfort, burning and/or tightness; cool skin and blanching; decreased or stopped IV flow rate.
