Renal Failure and Dialysis Flashcards
What does glomerular filtration rate (GFR) in chronic kidney disease show?
a. How much glucose is being filtered in the blood
b. How well the kidneys are filtering to remove waste and water
c. How much urine is being outputted
d. If one has chronic kidney disease or not
how well kidneys are filtering to remove waste and water
What are some causes of Chronic Kidney Disease?
a. Heart disease, older age, diabetes
b. Bleeding, diet, broken bones
c. OCD, diabetes, genetics
d. Crying, itching, tiredness
e. ADHD, anxiety, age
heart disease, old age, diabetes
Which is NOT a type of renal failure?
a. Acute Kidney Injury
b. Chronic Kidney Disease
c. End Stage Renal Disease
d. Kidney deficiency disorder
kidnet deficiency disorder
Which of the following is hemodialysis NOT dependent on?
a. High blood flow
b. Volume of blood
c. A filtrate
d. Negative pressure
negitive pressure

a. Diffusion
b. Adsorption
c. Conservation
d. Ultrafiltration
diffusion, absorbtion, ultrafiltration
Which of the following is relevant to the peritoneal dialysis cycler?
a. Used over night while sleeping
b. Has alarm system to notify patient
c. Uses positive pressure to move fluid out of cassette into patient
d. All of the above
all of the above
. What are the different types of renal replacement therapies?
a. Ultrafiltration, Absorption, and Diffusion
b. Hemodialysis, Peritoneal Dialysis, Continuous Renal Replacement Therapies
c. Convection, Continuous Renal Replacement Therapies, Ultrafiltration
d. Hemofilter, Continuous Renal Replacement Therapies, Adsorption
hemodialysis, peritoneal dialysis, continuous renal replacement therapies
What type of Continuous Renal Replacement Therapy removes only fluid and no solutes?
a. Slow continuous ultrafiltration
b. Continuous venovenous hemofiltration
c. Continuous venovenous hemodialysis
d. Continuous venovenous hemodiafiltration
slow continuous ultrafiltration
What are the 4 influencers in solute removal and explain what they are?
permability of membrane- dictates what molecules are able to pass
solute size- can it pass though the membrane
degradation of filter- molecules once not able to pass through now can
pressure gradient- flow from high to low
Name the three types of renal failure.
acute kidney injury, chronic kidney disease, and end-stage renal disease.
What kind of fluid and solute removal mechanism(s) does Hemodialysis use?
ultrafiltration and convection
. Explain the difference between hemodialysis and peritoneal dialysis
- Hemodialysis requires the use of an artificial kidney system in order to filter blood, whereas peritoneal dialysis is less invasive, requiring the use of a catheter to deliver dialysate and remove waste after.
. There are four types of Renal Replacement Therapy, choose one and explain its primary goal.
Slow continuous ultrafiltration (SCUF) - Primary goal: remove patient fluid
What is hemodialysis and how is it used to treat renal failure.
uses ultrafiltration and convection in order to filter. Ultrafiltration (dialyzer) removes small solutes. Convection- influences membrane permeability
It uses positive pressure to take blood filtered by a dialyzer and put it back into the body
It is essentially an artificial kidney that allows filtration when kidneys are failing
How is adsorption used in dialysis?
absorption is the molecular adherence to a surface or interior of a membrane
using this principle in the filters used in dialysis can allow for the removal of solutes, toxins, and fluids (smaller ones in particular)
it is ideal for short term dialysis
