Q

Dacron cuff helps secure and ___ ____

A

prevent infection

25
common sites for tunneled CVAD:
subclavian vein, IJ (internal jugular vein), can also be placed in a femoral vein
26
tunneled CVAD can have ____
multiple ports
27
nurses cannot do what with tunneled CVAD?
discontinue because they need to be surgically removed because the dacron cuff needs to be cut out
28
implanted port: port-a-cath, infusaport
surgically implanted line underneath
29
implanted port: port-a-cath, infusaport are tunneled through
jugular, subclavian, or cephalic/basilic vein
30
implanted port are long term: ____ to ____
month to years
31
implanted port: port-a-cath, infusaport are used for ____ through a ____ or ____
chemotherapy; single or dual port
32
____ needle to access an implanted port
huber
33
CVAD knowledge & care (5)
1. always assess the CVAD site before any interventions - sites/sutures/dressing/date, lumens/clamps, and fluids/meds 2. always "scrub the hub" (max-zero cap) at least 15 seconds before accessing 3. Always program CVAD infusions to a pump 4. flush lumen(s) using only 10 mL flush syringes 5. dressing changes
34
when do you flush lumens?
every shift, after every medication, and after every blood draw
35
when do you change dressings for CVAD?
24 hours post-insertion and every 7 days & PRN, the max-zero caps every 7 days with dressing change & PRN
36
Complications of CVAD: CLABSI
central line associated blood stream infection - most common complication
37
signs and symptoms of CLABSI
redness, drainage, swelling, discomfort at insertion site, fever, chills, tachycardia, and increased WBC
38
nursing interventions to prevent clabsi
strict asepsis, never touch with bare hands, clean injection ports with alcohol swab before every access, assessment, dressing changes as indicated, pt/family teaching
39
complications of CVAD: pneumothorax
air in the pleural space outside the lung (collapsed lung)
40
signs and symptoms of pneuomothorax
dyspnea, hypoxia, tachycardia, restlessness, cyanosis, chest pain, decreased breath sounds, obvious "chest deformity"
41
nursing interventions for pneumothorax
monitor vital signs, administer oxygen, notify physician, CN, RRT, and prepare chest tube if indicated
42
complications of CVAD: venous air embolism
air entering the circulatory system
43
signs and symptoms of venous air embolism
acute dyspnea, chest pain, headache, confusion, hypotension, hypoxia, and tachycardia
44
nursing interventions for venous air embolism:
keep lumens clamped, administer oxygen, monitor VS, pulse ox, place patient on left lateral side in trendelenburg position
45
why do you place patient in trendelenburg position for a nursing intervention for venous air embolism?
trap air embolism in right atrium so it doesn't leave and go to the rest of the heart or brain
46
complications of CVAD: occlusion
lack of blood return or sluggish flow
47
complications of CVAD: thrombosis
clot that blocks the catheter's lumen
48
complications of CVAD: catheter rupture
may be caused by excessive force used while flushing and wrong flush syringe
49
complications of CVAD: catheter migration
displacement or lengthening of catheter
50
catheter occlusion nursing interventions:
if no blood return or will not flush, have patient take deep breaths/cough, raise arms overhead/position arm on same side as the catheter, have pt sit up/stand up, change positions in bed, place in trendelenburg, administer alteplase
51
alteplase is used for?
dissolve blood clots that have formed in the blood vessels
52
CVAD catheter removal:
Dr's orders, CVAD kit, suture removal kit, petroleum based gauze hold pressure 5 minutes or until bleeding stops
53
position for CVAD catheter removal:
supine position, hold breath, and pull line with deliberation
54
how long do you hold pressure after CVAD catheter removal and remain in ____ position for at least ____ minutes post-removal
supine; 30 minutes
55
CVAD catheter removal PICC line:
same as catheter removal, cover with occlusive dressing and leave on for 48 hours, must add 4x4 folded gauze over occlusive dressing & secure with Coban wrap, measure catheter length of PICC line and record, 30 min supine position
56
how long do you leave on occlusion dressing after removal for CVAD?
24 hours
57
CVAD dressing change steps:
gather supples (extra sterile gloves), introduce self and procedure, hand hygiene, identify pt, allergies/readiness, raise bed level of comfort, place patient in supine position with HOB 30 degrees if tolerated, position overbed table, hand hygiene, assess site/lumes/clamps, apply gloves/clean over-bed table, remove gloves, HH, open CVAD kit, then follow kit steps
58
how long do you scrub the insertion site and what motion? what order?
30 seconds, back and forth, insertion site, hub, lumens
