NUR 211 Test 6
- Why do you use CVADs
Answer For people who need frequent or special access to the vascular system.
- What are the three main types of CVAD's
Answer Centrally, inserted, catheters, peripherally, inserted central catheter (PICCs), and implanted ports.
- Where are CVAD's placed
Answer Large blood vessels
subclavian vein and jugular vein
- What are the advantages of CVADs
- Immediate access to the central venous system
- a reduce need for multiple venipunctures
- decrease risk for extravasation injury.
- frequent, continuous, rapid, or intermittent administration of fluids and medication.
- Administer more safely blood, blood products and drugs that are potential vesi- cants.
- Useful with patients who have limited peripheral vascular access or who have projected
- Can also use to inject radiopaque contrast media.
Answer
need for long-term vascular access.
- What are vesicants?
Answer Agents deck and caused tissue damage
- What are major disadvantages of CVAD's 1 / 4
Answer
- Increased risk for systemic infection
- Invasiveness of the procedure.
- Extravasation can still occur if there is displacement of or damage to the device.
- Where are non-tunneled catheter usually placed
Answer The subclavian, or internal jugular vein, I more rarely in the femoral vein
- T or F
centrally, inserted, catheters are best for patients with short term needs in an acute care settings.
Answer True
- What are some surgically placed tunneled catheter's?
Answer Hickmann, Broviac, Groshong.
- T or F
surgically placed tunneled catheter's are suitable for long-term needs
Answer True
- The tip of centrally inserted catheters, also called, central venous catheter's (CVCs) rest in
the distal end of
Answer The superior vena cava, near its junction with the right atrium. And the other end exists through the separation incision on the chest or abdominal wall.
- What is a PICC line?
Answer A central venous catheter inserted into a vein in the arm 2 / 4
- What is the best vein to insert a PICC line
Answer The basilic vein, because of its large diameter.
The cephalic, median cubital or brachial veins are other options
- PICCs are used with patients who need vascular access for how long
Answer One week to six months but they can be in place for longer periods.
- Advantages of PICC over CVC
Answer -Lower infection rate
-fewer insertion related complications -decrease costs -ability to insert at the bedside or in an outpatient area.
- T or F
Do not use the arm with the PICC to take a blood pressure reading or draw blood
Answer True
- PICCs have an increased risk for
Answer Deep vein, thrombosis, and phlebitis
- T or F
phlebitis occurs. It usually happens within 7 to 10 days after insertion of a PICC line.
Answer 3 / 4
True
- What is an implanted infusion port?
Answer -A surgically implanted, central venous catheter connected to a reservoir or port.
-The catheter tip lies in the desired vein.-The port lies in a surgically created subcutaneous pocket on the upper chest or arm.-It consists of a titanium, or a plastic reservoir, covered with a self sealing silicone septum
- How do you access an implanted infusion port?
Answer -You access the port by using a special noncoring needle with a deflected tip.
-This prevents damage to the septum that could make the port useless.
- What is the benefit of implanted infusion ports?
Answer -They are good for long-term therapy
-low risk for infection -Hidden port offers patients cosmetic advantages -overall has less maintenance than other types of CVAD's.
- What should you monitor with implanted in fusion ports
Answer Infiltration that can occur if the needle is not in place or dislodged
- Midline catheter's
Answer -Don't enter a Central vein
-Use and care are similar to a PICC -A specially trained nurse can insert a midline catheter -Can be 3 to 8 inches long and have single or double lumen -Insertion in the antecubital area, through either the basilic or cephalic vein often under ultrasound guidance
