Question | Answer |
Three categories of CVADs: | *Tunneled CVCs *Percutaneous CVCs *Implanted infusion ports |
Where are Percutaneous Central Catheters inserted? | *Inserted through the chest wall into the subclavian vein *Inserted through the neck into the internal jugular vein |
What is the Alternative for patients requiring long term IV access | Peripherally Inserted Central Catheters (PICC) |
True or False: PICC poses less risks of complications than CVCs | True. |
How far does a PICC extend in the body? | The PICC extends into the distal third of the superior vena cava |
How long is a PICC? | 45 to 65 cm in length |
How long can a PICC remain in place? | 6 months or more |
How long can CVCTs remain in place? | Several years |
What does CVCT stand for? | Central Veinous Tunneled Catheter |
True or False: PICCs and CVCTs May have several lumens with different ports thus facilitating simultaneous infusions of several solutions | True. |
Examples of CVCTs | Broviac, Groshong, Hickman. |
How are CVCTs inserted? | Implanted surgically through a subcutaneous tunnel. |
Where are implanted vascular access devices normally located? | In the client's upper chest. |
What kind of needle do you access an implanted vascular access device with? | Huber needle . |
List 3 Reasons for Implanted Device Placement | *Long term IV therapy *Need for frequent venous access *Central venous pressure monitoring (CVP) *Total parenteral nutrition (TPN) *Self administration of treatment *Sclerosed veins *Limited peripheral venous access |
What is supposed to be done with un-used lumens prior to accessing a vascular device? | They must be flushed(usually Heparin flush 100 units/ml). |
How often must un-used lumens in a vascular device be flushed? | Every 8 hours (usually Heparin flush 100 units/ml). |
When should the dressing over a vascular access device first be changed? | within 24 hours. |
How often does the dressing over a vascular access device need to be changed after the initial dressing change? | Every 7 days. |
Caps placed on central lines when not in use should be changed how often? | Every 3-7 days |
True are False: The client does not need to wear a mask during dressing changes. | True. However, if the client is not wearing a mask, they need to have their head turned away or face covered. |
Label each lumen or port of the vascular access device tubing with what? | A description of its purpose. |
True or False: The Practical Nurse/68WM6 can administer medications directly into a veinous access device | False. |
What is the SASH method in terms of delivering medication in a vascular access device? | *SALINE *ADMINISTER *SALINE *HEPARIN |
Why is the SASH method used? | Many medications are not compatible with heparin |
Heparin maintains patency by? | Preventing clotting |
What is a MAJOR complication of Vascular Access Devices? | Air Embolism |
What are the signs of symptons of an air embolism? | Anxiety and Dyspnea |
How do you treat an air embolism? | Administer 100% oxygen, position client in left Trendelenburg position and notify physician. |
What is a thrombus occlusion? | Clot formed at catheter tip related to fibrin build up. |
What is a precipitate oclusion? | Drugs that interact may cause precipitate that blocks catheter tubing. |
What drug is generally used to break up a thrombus occlusion? | streptokinase. |
List three complications of VADS | Infection and sepsis, Air embolism, Thrombus occlusion, Precipitate occlusion, Mechanical occlusion. |
What are mechanical occlusions? | *Catheter may have moved out of proper placement. *Opening at catheter tip may be up against wall of vessel. |
