Central Venous Access Devices (AI Generated Questions, Unsure Of Quality) Flashcards
What is the purpose of a central venous line catheter?
To administer medications, fluids, blood products, or nutrients directly into the bloodstream.
True or False: Central venous line catheters are typically inserted into a large vein in the neck, chest, or groin.
True
What are the three main types of central venous line catheters?
Peripherally Inserted Central Catheter (PICC), Tunneled Central Venous Catheter, and Implanted Port.
Fill in the blank: Central venous line catheters are used for patients who require _______ or ________-term intravenous therapy.
long, short
What is an advantage of using a central venous line catheter over a peripheral IV?
Ability to deliver medications and fluids that may be irritating to smaller veins.
What is a potential complication of central venous line catheter insertion?
Infection, thrombosis, or pneumothorax.
True or False: Central venous line catheters are typically sutured in place to prevent movement.
True
What is the most common indication for central venous line catheter use in critically ill patients?
Hemodynamic monitoring.
What is the purpose of the guidewire during central venous line catheter insertion?
To guide the catheter into the vein.
What is the recommended frequency for changing the dressing around a central venous line catheter?
Every 7 days or sooner if it becomes damp, loosened, or soiled.
True or False: Central venous line catheters are typically removed by pulling on the catheter.
False
What is the main advantage of using a peripherally inserted central catheter (PICC)?
Lower risk of infection compared to other central venous line catheters.
What is a potential complication of using a tunneled central venous catheter?
Catheter-related bloodstream infection.
Fill in the blank: An implanted port is placed under the skin and connected to a _________ that is inserted into a central vein.
catheter
What is the advantage of using an implanted port for long-term intravenous therapy?
Reduced risk of infection and improved cosmetic appearance.
True or False: Central venous line catheters can be used for blood draws in addition to medication administration.
True
What is the recommended method for flushing a central venous line catheter to prevent occlusion?
Using a syringe filled with normal saline or heparin.
What is the purpose of the clamp on a central venous line catheter?
To prevent blood from leaking out of the catheter when not in use.
True or False: Central venous line catheters are typically inserted by a nurse without the need for a physician.
False
What is the primary goal when caring for a patient with a central venous line catheter?
Preventing infection and maintaining catheter patency.
Fill in the blank: Central venous line catheters are often used in patients who require frequent _______ or ________ access.
blood, medication
What is the recommended technique for securing a central venous line catheter to the skin?
Using a sterile dressing and securement device.
What is the appropriate angle for inserting a central venous line catheter into the vein?
About 15-30 degrees.
True or False: Central venous line catheters are typically indicated for patients with stable hemodynamics.
False
What is the maximum recommended dwell time for a tunneled central venous catheter before replacement?
Every 3-6 months.
What is the main disadvantage of using a tunneled central venous catheter compared to a peripherally inserted central catheter (PICC)?
Higher risk of infection due to the longer dwell time.
True or False: Central venous line catheters can be used for administering total parenteral nutrition (TPN).
True
What is the primary advantage of using a central venous line catheter for administering chemotherapy?
Minimizing the risk of extravasation injury.
What is the recommended procedure for verifying central venous line catheter placement?
Confirming by chest X-ray or ultrasound.
You are inserting a CVAD into the patient. Where should the CVAD stop at?
The Superior Vena Cava or the Inferior Vena Cava (depending on the route that is taken)
The Proximal Lumen is used for -
Meds + Blood
The Distal Lumen is used for -
Blood / Viscous Fluids
The Medial Lumen is used for-
Parenteral Nutrition
