Renal Replacement Therapy (RRT) Flashcards
Renal Replacement Therapy : ?
These therapies take over or replace the kidney function
When Is Renal Replacement Therapy started ?
- When BUN & Creatinine levels can’t be decreased
- FVE is compromising the heart and lungs
- Hyperkalemia and metabolic acidosis can’t be treated successfully
In Hemodialysis what is the machine ?
The machine is the glomerulus (filter)
How often is Hemodialysis done ?
Done 3-4x per week
so, the client has to watch what they eat and drink between treatments
Why are clients on Hemodialysis given anticoagulants during therapy ?
to prevent blood clots from forming
Anticoagulant is usually Heparin (implement bleeding precautions)
Before Hemodialysis begins, what do you want to assess for ?
Assess fluid status
What is watched constantly during Hemodialysis ?
Electrolytes & Blood pressure
Can all clients tolerate Hemodialysis ?
No
What clients can’t tolerate Hemodialysis ?
Unstable cardiovascular system CAN’T tolerate hemodialysis
Clients getting Hemodialysis must have what ?
Vascular access
What Is happening with Hemodialysis ?
Blood is being removed, cleansed, and then returned at a rate of 300 to 800 mL/min
What is a Vascular access ?
A site where they have access to a Large blood vessel because very rapid blood flow is essential for Hemodialysis
What are types of Access ?
- AVF (arteriovenous fistula)
- AVG (arteriovenous graft)
What is an AVG (arteriovenous graft) ?
A synthetic graft to join the vessels
where is an AVF (arteriovenous fistula) located ?
In the forearm with an anastomosis between an artery and a vein
What do both vascular accesses (AVF & AVG) require for placement ?
Both require surgery
The vascular accesses sites take how long to be ready for repeated venipunctureus ?
The access site takes weeks to mature & be ready for repeated venipunctures
During dialysis how many needles are inserted into the vascular space ?
two needles
Why are two needles needed with hemodialysis ?
- One needle will allow blood to be pulled from the circulation and sent to the hemodialysis machine
- The other needle is used to return the filtered blood to the client’s circulation
With Hemodialysis, the _________ end of the access will remove the blood and the return is through the low pressure ___________ end ?
- Arterial
- Venous
With Hemodialysis, what locations are used for temporary access ?
The internal jugular or Femoral vein is often used for catheter placement
Is Surgery required for temporary vascular access ?
No
You do not use a client’s vascular access for what ?
For IV access (drawing blood, administering medications, etc)
When a client has an alternative vascular access, what Is the associated nursing care for that extremity ?
- No blood pressure
- No needle sticks
- No constriction on that arm at ALL (no watch, purse, etc)
