Unit 7: Tubes, Lines, And Catheters Flashcards
Discuss common location for peripheral access
Typically in the arm ( antecubital region, wrist, or the hand)
Discuss the needle vs the catheter
Only the plastic catheter remains in the patient, the needle is removed
Discuss the difference between heparin lock and a saline lock
An saline lock is an IV access nut it’s not attached to a continuous drip like the heparin lock
What is the purpose of a central venous line
Line that terminates in the heart for long term access
Where are common locations for central venous lines to be inserted
Jugular vein
Subclavian vein
Umbilical vein and artery
Femoral vein
What is a PICC line
It’s a peripherally inserted central catheter used for long term access for meds, TON, and antibiotics
Discuss a subclavian PICC line
Central line that goes directly from skin into vein
Has significant risk of a pneumothorax
Discuss a Hickman-Broviac- Groshong PICC line
Long term line mainly used for dialysis patients
Tunneled under the skin before entering the bloodstream
Discuss a port-a-cath
It’s completely internal and has a easy venous access
Discuss a swan-ganz PICC line
Used for cardiac patients
Terminates in the pulmonary artery
What is an interosseous infusion
Used If an IV access is not an option
Fluids will get fused into marrow
Define ECMO
Extra Corporeal Membrane Oxygeneation
What does ecmo do
It’s a lung bypass that allows time for underlying conditions to resolve
What is infiltration and extravasating
Fluid leaking into surrounding tissue instead of the vein
What is the difference between extravasation and infiltrate
The difference is the fluids
Extravasation is vesicant fluid like medication like contrast
Infiltrate is non vesicant like saline
What is phlebitis
Inflammation of the walls of a vein
What is an air embolism
A bubble or air in an artery or vein
Discuss drug incompatibility
Some drugs don’t mix well with certain solutions or other drugs
What is low fluid level
When the fluid in the container is at a low level
Discuss a nasogastric tube
NG tube goes from nose to the stomach and is used to remove gastric contents band remove air
Discuss feeding tubes
Through the nose and ends in the duodenum and is used to deliver TPN
Discuss chest tubes
Used if patient has pneumothorax or hemothorax
Discuss urinary catheters
Used to drain urine
Discuss a foley bag
Used to drain urine for long term use and must be kept below patient level to prevent backwash
