Medsurg 3 part 3 Flashcards
Functions of Dialysis: Rids the body of
excess fluid and electrolytes
Functions of Dialysis: Achieves
acid-base balance
Functions of Dialysis: Eliminates
waste products
Dialysis can sustain life for clients who have both
acute and chronic renal failure
Dialysis does not replace the ___ functions of the kidneys.
hormonal
Two types of dialysis are
hemodialysis and peritoneal dialysis
Hemodialysis works by
shunting the client’s blood from the body through a dialyzer and back into circulation.
Vascular access is needed for hemodialysis.
2 less obvious indications for Hemodialysis
drug OD
Persistant hyperkalemia
following surgical development of AV fistula,
elevate the arm to reduce swelling
A kind of medication that should be held before dialysis
meds that lower BP
Have ___ sulfate ready to reverse heparin if needed.
protamine
Advise the client not to ___ during dialysis.
eat
Expected findings after dialysis
Decreases in blood pressure and laboratory values
1 liter weighs
1 kg
Avoid invasive procedures for ___ hours after dialysis due to the risk of bleeding related to an anticoagulant.
4 to 6
Check the access site at intervals following dialysis, if bleeding
apply light pressure
Contact the provider if bleeding from the insertion site lasts longer than ___ following dialysis
30 min
Dialysis: Eat well-balanced meals to include foods high in ___ (beans, green vegetables), and take ___ supplements
folate
protein
Dialysis: Perform ___ exercises that promote fistula maturation.
hand
Dialysis complication: caused by too rapid a decrease of BUN and circulating fluid volume
Disequilibrium syndrome
Disequilibrium syndrome: may result in
cerebral edema and increased intracranial pressure
Use a slow dialysis exchange rate, especially for
older adult clients and those being treated
with hemodialysis for the first time
Nursing action for Disequilibrium syndrome: you may need to administer
anticonvulsants/barbiturates
Hypotension caused by dialysis: first 2 steps
give IV fluids (which raises BP) and slow the dialysis rate
Hypotension caused by dialysis: position the pt
HOB lowered
Hypotension caused by dialysis: For severe hypotension that is unresponsive to fluid replacement
discontinue the dialysis
Peritoneal dialysis definition
you put of hypertonic dialysate solution into the peritoneal cavity.
Allow the solution to sit in the peritoneal cavity.
Drain the solution that includes the waste products.
In Peritoneal dialysis, the filtration membrane is the
peritoneum
Peritoneal Dialysis is contraindicated in someone who has undergone
multiple surgeries involving the peritoneum (peritoneum must be intact for the process to work)
Peritoneal dialysis is the treatment of choice for
older adults
- unable to tolerate anticoagulation.
- Have difficulty with vascular access.
- Have chronic infections or are unstable
These are indications for
Peritoneal dialysis
Continuous ambulatory peritoneal dialysis (CAPD) frequency
7 days a week for 4 to 8 hours
Activity level allowed during CAPD
no restrictions
Peritoneal dialysis outflow color should be
clear, light yellow
Peritoneal dialysis outflow volume should be
equal or greater than input volume
___ the dialysate prior to instilling
warm (not in microwave)
Peritoneal dialysis may need to eat foods high in
protein (because protein can be excessively drained during the procedure)
Peritoneal dialysis are at risk for increased ___ and ___ levels because of the contents of the solution
high glucose and fat
Peritoneal dialysis: ___ tubing to break up fibrin clot.
Milk
Peritoneal dialysis: Tell the client to avoid constipation by
using stool softeners and consuming a diet high in fiber
