Exam 1: Perioperative nursing and IV therapy/venipuncture Flashcards
Nursing role for IV therapy
Venipuncture/insertion
Setting up equipment
Calculating infusion rate
Setting up pumps
Frequent observations
Determining site
Determining gauge
Determining when to remove IV and change sites if complications occur (phlebitis, infiltration, infection)
Patient education
Discontinuing
What should be assessed before IV therapy?
Medical dx
Has the patient had IVs before?
Hx of vasovagal reaction during previous venipuncture or seeing blood?
Activity level
Is the patient on anticoagulants?
Labs (Platelets, PT, INR)
Hx of fainting
Mastectomy
When should the RN ask the HCP for CVC or PICC?
Veins are poor or non-existent
Therapy is longer than 1-2 weeks
Therapy is irritant, vesicant, or hypertonic
Pt is going home on IVs for more than 1-2 weeks
How should the RN choose size of the IV device?
Expected duration of therapy
type of therapy
conditions of the patient’s veins
patient preference
RN/physician preference
Why would the RN choose a larger gauge (smaller number)?
If the solution is viscous
For rapid infusions during hemorrhage or shock
Why would the RN choose a smaller gauge (bigger number)?
Better blood flow around the catheter
Less discomfort
lower risk of phlebitis/thrombosis
How to choose the IV site
non-dominant extremity
round, stable, bouncy, straight vein
begin distal and work up
Veins to avoid
sclerosed or thrombosed veins (hard)
edema, inflammation, bruising
veins distal to previous IV infiltration, phlebitis, or scar
arm vein located on the same side as a mastectomy, CVA, or renal fistula
sites that interfere with surgery
joints and areas of flexion
impaired circulation
How to promote vein distention
tourniquet
BP cuff at 30 mm/Hg for fragile veins
warm moist compress for 10 minutes
gravity - hang arm below heart level
tap vein with fingers - do not slap
hydrated pt
multiple tourniquets
massage arm from proximal to distal end
What sites should the RN avoid sticking?
superficial antebrachial (near wrist) - sensitive and difficult to move around with
metacarpal veins (on hand) - last resort for elderly because their skin is fragile and it can result in bleeding and hematomas
feet - never use for diabetics and must have an order to use this site, can cause complications
digital veins - fragile veins, only can be used for isotonic solutions
how often should the RN rotate IV sites?
every 72h and prn
what gauge IV catheters are usually used for surgeries?
16-18 gauge
What size gauge is most commonly used?
20 gauge, 1-1.5 in
How should the IV site be prepared?
clip hair if needed, do NOT shave
chlorhexidine or alcohol and betadine scrubbed for 30 seconds (if allergic to both use alcohol x4 and keep skin wet for 1 minute)
What should the RN include on the IV site label?
date, time, initials, and gauge
What should the RN do if they are unable to access the vein or the vein blows?
release tourniquet
place gauze over the site and remove catheter
hold pressure for 1-3 min
assess the angiocatheter to ensure it is intact
tape gauze with pressure
try another site, if unable to do it again, have another RN do it
if starting in the same arm keep the other IV in place until the new one is started
How should the RN assess the IV?
check for pain, tenderness, redness, swelling, leaking
dressing is intact
tubing is taped securely
pt condition and response to therapy
IV is infusing properly
IV rate every time the RN enters the room
do not touch the bag while checking the volume of the bag
check F&E
what to do if a hematoma forms
release tourniquet immediately and remove the needle, apply firm pressure
What is phlebitis and what are the signs and symptoms?
vein inflammation
most common problem
causes: mechanical, chemical, bacterial, or post-infusion
s/sx: streak formation, palpable venous cord, vein may be thrombosed, IV flow may stop, might have purulent drainage
How can phlebitis be prevented?
rotating the IV site every 72-96 hours or at the first sign of phlebitis or infiltration
What should the RN do if they suspect phlebitis?
discontinue the IV
elevate the extremity and apply warm moist compress
notify physician
What is infiltration?
dislodgment of the cannula from the vein causes infusion into the subcutaneous tissue
signs and symptoms of infiltration
blanching
swelling
pallor
pain
during aspiration, blood may return with partial infiltrate or no blood may return
infiltration treatment
discontinue IV
elevate
apply warm moist compress or cold depending on what was infiltrated
extravasations
infiltration of a medication that may cause tissue injury or necrosis
what might cause extravasations?
chemotherapy
phenergan
dilantin
total parenteral nutrition
what should the RN do if they suspect an extravasation?
notify physician
IV infection s/sx and actions the RN should take
redness, warmth, tenderness, purulent drainage
replace IV, notify MD, culture drainage or catheter
venous spasm and actions the RN should take
pain along the vein track, can be caused by cold or irritating solution
assess for phlebitis, infiltration
apply warm moist compress to vein
slow the infusion prn
What should the RN do if a catheter embolism is suspected?
do not reinsert the needle
do not apply pressure
apply tourniquet above the site and send the pt to radiology with MD order
air embolism and s/sx
air gets into the venous system (50 ml over 3 sec) blocking pulmonary circulation
s/sx: chest pain, anxiousness, wheezing, tachypnea, hypotension
causes of air embolisms
loose connections - end open to air
air in IV line - did not prime tubing, glass bottle, vented tubing, dry plastic bag gravity infusion
air embolism treatment
call for help
clamp catheter
place on left side in trendelenburg
administer O2
aspirate air prn
general guidelines to prevent complications
hand washing and aseptic technique
prep skin well
rotate site q 72-96 h or at 1st sign of phlebitis or infiltrate
hang hydration bag for no longer than 24 h and change when some fluid is left to avoid running dry
secure catheter to prevent movement and contamination
assess site and pt q4h for adults and q2h for children and each time you enter the room
educate pt on s/sx of complications and when to call the nurse
what is the vein of choice for venipuncture?
median cubital vein
-it is more stationary than others, less painful to puncture, closer to the surface of the skin, and is not nestled among nerves and arteries
order of draw for blood cultures
red or tiger top
blue top
green top
lavender top
gray top
how much blood is collected from each site for a blood culture?
10-15 ml in a 20ml syringe
for anaerobic and aerobic cultures which should be inoculated first?
anaerobic bottle first
how should the blood culture be labeled?
at the bedside
pt name, date, time, and RN initials
send to the lab within 30 minutes
pt education after venipuncture
-do not bend arm - can cause bleeding in AC area compromising vessels and nerves
-keep arm straight and elevated while applying pressure
-keep dressing in place for a few hours
assessments and documentation after venipuncture
assess for bleeding or bruising
record:
-method used to obtain specimen, date and time collected, type of test, lab receiving specimen
-site after collection
-pt tolerance to procedure
