1
Q

What are the purposes of establishing an IV?

A
  1. Helps maintain or restore the fluid volume and electrolyte balance of the body.
  2. Provide a way to nourish and feed a patient calories.
  3. A way to give needed medication (both routine and emergent) – such as pain meds
  4. To transfuse blood products.
  5. To provide avenue for diagnostic lab testing.

Q

What is a central line?

A

An access device that terminates in a central vein (superior vena cava).

53
Q

What are the different types of central line?

A
  1. PICC (peripherally inserted central catheter) - cephalic, basilic, brachial
  2. Jugular vein (Internal jugular = IJ) or subclavian vein usually secured with sutures.
  3. Ports and Quinton catheters are inserting in the subclavian vein.
54
Q

What is the lumen part of the central line?

A

There is single, double or triple; each lumen its its own tube. The medications do not mix until the CVC.

55
Q

What is the port part of the central line?

A

Where you attach the IV via Luer-lock.

56
Q

What is a stat lock part of the central line?

A

A winged securement device applied underneath the PICC line and then the wings are clipped over it.
There is an opening on each side of
the PICC to nest into the stat lock; When applied, use skin barrier prep
(it’s sticky); When removed, use alcohol

57
Q

What is a biopatch?

A

CHG infused “patch” that you place
over the entrance of the skin; Has a slit in it to place around the
catheter; Be careful not to dislodged catheter
when changing the dressing

58
Q

What do we use to identify the vein when placing a central line? Where is it performed?

A

Ultrasound; bedside

59
Q

What is lidocaine for a central line used for?

A

It is administered intradermally to numb the skin.

60
Q

How is the placement of a central line confirmed?

A

X ray

61
Q

What are the responsibilities of the RN with respect to central lines?

A
  1. Placing supplies at the bedside.
  2. PICC line placement checklist/witness to patient consent.
  3. Assisting with the procedure
  4. assessing site
  5. educating pts and families
  6. changing the dressing
  7. monitoring the site
  8. know the catheter (midline, PICC line, power or not, french size, lumens?)
62
Q

What are the indications of the central line?

A

-Long term antibiotics (>28 days, up to 18 months)
-Medications too caustic (vesicants, irritants) for smaller veins (levophed)
-Long term nutrition (TPN)
-Chemotherapy
-Limited peripheral access
-Emergencies
-Frequent blood draws

A

True

68

True

69

Infection (CLABSI), phlebitis, catheter breakage, pneumothorax, nerve damage, air embolism, arterial insertion, superior vena cava syndrome

71

A

Central line associated bloodstream infections

72
Q

What are some causes of CLABSI?

A

-Treatment is not reimbursed by medicare/medical if not present on admission.

73

drainage, warmth, edema

-24 hours after placement
-then every 5-7 days depending on hospital policy
-when soiled or loose

76
Q

When would you remove a central line?

A

Per provider order

77
Q

What are some nursing considerations when removing a central line?

A

-Ask patient to take a deep breath and hold or bear down to prevent venous air
embolism
-Do not pull if resistance is met

78
Q

When removing a central line, what is considered a vascular emergency?

A

If the distance removed does not match that inserted, a piece of catheter could be inside
the patient. Notify provider immediately (this is a vascular emergency)

79
Q

What is a midline?

A

-A midline catheter is inserted into the arm
peripherally (brachial, cephalic, or basilic
veins)
-IT IS NOT A CENTRAL LINE
-Length: 8-15 cm and terminates in subclavian

80
Q

What is a precaution with respect to midlines?

A

It can look very similar to a PICC line

81
Q

What are some uses for a midline?

A

-Short-term antibiotics (<28 days)
-in patients with difficult venous access
-can run the same medications as peripehral IVs but not the same as a central line.
