CVAD
| Question | Answer |
|---|---|
| Discuss the 4 types of CVAD's. | *Non tunneled catheter - Triple lumen catheter (TLC) *Tunneled catheter - Hickman; Ashcath *Peripherally Inserted Central Catheter (PICC) *Implanted port - Portacath |
| Describe placement of distal tip of catheter. | *IV catheter located in a central VENOUS vessel (internal jugular, subclavian, or femoral vein) *Distal tip of the catheter resting in the superior vena cava just above the right atrium *Xray to check placement prior to using |
| Identify symptoms of pneumothorax. | *S/S: SOB, CP, cough, hypotension, tachycardia, anxiety |
| What should you do in the event of an air embolism? | *Make sure all lumens are closed *Place on left side; head down; Trendelenburg position *Administer 100% O2; continuous O2 Sat monitoring *Page surgeon Stat *Ensure IV access *Draw labs and assist with Xray and ECG |
| Explain uses of tunneled catheter. | *Tunneled catheter is inserted into central vein and remainder is tunneled subcutaneously to a distant exit site *Tunneling helps secure catheter in place and reduces incidence of infection *Dwell time - may remain in place for several months to years |
| Explain uses of PICC lines? | *PICC inserted in upper arm but its tip goes past shoulder and ends in the superior vena cava *Chest xray to confirm proper placement *Stays in place for a year or more |
| Explain uses of implanted ports. | *Totally implanted under skin; more cosmetically appealing *Must use Huber non-coring needle to access them *Long term CVAD |
| Why is saline flushing of a central line so crucial? | *Helps confirm catheter's patency *Avoids drug incompatibilities *Ensures entire drug dose is given *Prevents thrombus formation (10 mL to flush) (every 8 hours in PICC lines) |
| What are the steps in Blood Sampling Method? | *Use 10 mL syringe (w/ 2mL NS) withdraw 5-10 mL of blood and DISCARD *Connect new 10mL syringe and withdraw amount of blood needed for order *Flush catheter w/ 10 mL NS *Close clip |
| What are the steps in Administering Medication? | *Attach 10mL syringe NS *Open clip *Aspirate for blood return (confirms patency) *Saline flush *Administer meds *Saline flush *Maintain positive pressure |
