NSE 221 WEEK 2 WITH COMPLETE SOLUTIONS 100% VERIFIED!!
PIV dressing changes - ANSWER - occlusive
- transparent to allow for inspection of IV site
- label with date, time, initials
Central venous access devices - ANSWER catheters placed in large blood vessels of
people who require frequent or special access to the vascular system
Indications for use CVADs - ANSWER Cancer, infection, pain, drugs that increase risk
for phlebitis, nutritional replacement, blood samples/transfusions, renal failure, shock,
burns, hemodynamic monitoring, heart failure, autoimmune disorders
Why are CVADs used? - ANSWER Long term administration of medications or solutions
that are irritating to the veins, the presence of poor peripheral veins, th ended for good
access to administer large volumes of fluid and the need for reliable measurement of
fluids
Advantages of CVADs - ANSWER Reduce the need more multiple veinpunctures,
decreased risk of extravasation injury, immediate access to the central venous system
Disadvantages of CVADs - ANSWER increased risk of systemic infection and the
invasiveness of the procedure
Centrally inserted catheter - ANSWER Tip rests in the distal end of the superior vena
cava near its junction at the right atrium, the other end exists through a separate
incision on the chest or abdominal wall
Nontunnelled catheters - ANSWER Usually placed in the subclavian or internal jugular
vein and rarely in the femoral vein and best for pts with short term needs in acute
settings
, Tunnelled catheters (Hickman) - ANSWER Surgically placed through subcutaneous
tissue and synthetic cuff provides stability and decreases infection risk - used for long
term needs
peripherally inserted central catheter (PICC) - ANSWER Inserted into a vein in the arm
(basilic) just above the antecubital fossa and end with the tip distal one third of the
superior vena cava and for pts who need vascular access 1 week to 6 months
Advantages of PICC over CVC - ANSWER lower infection rate, fewer insertion-related
complications, decreased cost, and ability to insert at the bedside or in an outpatient
area
Complications of PICC - ANSWER phlebitis, catheter occlusion which occurs within
7-10 days after insertion
Implanted ports - ANSWER CVC connected to a single or double implanted
subcutaneous injection port and drug is administered through the skin into the port -
huber needle to access
Advantages of ports - ANSWER Good for long term therapy and it is hidden for
cosmetic advantages
Complications of CVADs - ANSWER 1. Catheter occlusion
2. Embolism
3. Catheter related infection
4. Pneumothorax
5. Catheter migration
Clinical manifestation of catheter occlusion - ANSWER Sluggish infusion or aspiration,
inability to aspirate or infuse
