8
New cards

What type of dressing does a peripheral IV require?

an occlusive dressing (air- and water-tight

9
New cards

Who inserts a IJ central line? In what setting is it done?

By an MD at the bedside

10
New cards

What are some qualities of an IJ central line?

- used in acute care

- multi-lumen- flush unused lines with heparin

- sutured in place

- sterile dressing

- uncomfy

11
New cards

Qualities of a PICC line

- non-tunneled

- anchored with suture or statlock

- used in many settings

- used for infusions and blood draws

12
New cards

Who can insert a PICC line?

A specially trained RN/ RT/ MD

13
New cards

What is a risk of using a PICC line?

higher risk for venous thrombosis- assess for pain, swelling, heat

14
New cards

Why would a femoral catheter be placed?

when the upper torso sites are not available or accessible; in trauma or emergency situations

15
New cards

in what setting can a femoral catheter be placed?

at the bedside

16
New cards

what are some qualities of a femoral central line? (6)

- temporary

- secured with sutures

- requires sterile dressing

- site must be monitored closely

- limits pt mobility- cannot bend at hip

- uncomfy

17
New cards

in what setting is a PAC placed?

in interventional radiology

18
New cards

Qualities of a PAC (6)

- located under the skin

- can be in place for years

- often used for chemo

- requires non-coring needle

- flushed at least once a month

- sterile procedure to a access

19
New cards

How long can a PAC be accessed with the same needle?

7 days

20
New cards

In what setting is a tunneled central line inserted?

in interventional radiology or OR (also removed in OR)

21
New cards

A tunneled central line is anchored by 1-2 ______

cuffs

<p>cuffs</p>
22
New cards

Qualities of a dialysis line

- can be tunneled or non-tunneled (permcath/vascath/pheresis catheter)

- double or triple lumen (trialysis)

- red and blue lumens (red is for dialysis)

23
New cards

Assessment pieces for a central line (6)

- look at insertion and exit site for redness/swelling

- assess patency of each line

- integrity of each line (fluid leaks)

- clamps and caps present

- crepitus of chest

- pain in arm/shoulder/neck?

24
New cards

What does an exit site infection look like on a CVC?

localized erythema and edema at exit sire

25
New cards

What does a tunneled infection look like on a CVC?

inflammation along the subq track of the device greater than 2cm from exit site

26
New cards

Nursing management of a CVC (4)

- only access with 10 ml syringe

- all IV fluids must be on a pump

- ensure secured connections (aka luer lock tubing/syringes/caps)

- clamp line when not in use

27
New cards

Potential complications of CVC insertion (5)

- pneumothorax (rare)

- hematoma

- infections

- air embolism

- wrong vein

28
New cards

what is the #1 complication of CVCs

infection

29
New cards

Vascular catheter-associated infections are considered a _______ ________

never event

30
New cards

Central line bundle for preventing CVC infections

1) hand hygiene

2) maximum barrier precautions during insertion

3) chlorhexidine antisepsis on skin

4) optimal catheter site selection (avoid femoral)

5) daily review of need for central line

31
New cards

best practices for prevention of catheter-related bloodstream infection pertain to what aspects of CVCs? (3)

- dressings

- flushing

- connectors

32
New cards

best practices for CVC dressings (6)

- change when damp/loose/soiled

- change transparent dressing Q7days

- change gauze dressing Q24H
