A nephron is made up of: Correct Answer: A glomerulus and a tubule
The endocrine functions of the kidney includes: Correct Answer: Making erythropoietin and the
active form of vitamin D
The leading cause of End-Stage Renal Disease for adult in the United States is: Correct Answer:
Diabetes
Patients with kidney failure often complain of itching, which is likely to be caused by: Correct
Answer: Hyperphosphatemia
Why do kidney patients often have bone disease? Correct Answer: Kidneys stop producing
calcitriol
Symptoms that a patient may need more dialysis time include: Correct Answer: Anorexia,
fatigue, swelling
A semipermeable membrane is a porous barrier that: Correct Answer: Allow for only certain
sized particles to cross
Diffusion is movement of particles: Correct Answer: From an area of higher concentration
Negative pressure is pressure created when: Correct Answer: Fluid is pulled through a
restriction
During dialysis, ultrafiltration occurs when: Correct Answer: Water is removed from blood
because there is a pressure gradient between blood and dialysate
At which point in the extracorporeal circuit is the blood usually under negative pressure? Correct
Answer: The arterial line section before the blood pump
Which of the following will increase the amount of solutes that will diffuse across the
semipermeable membrane? Correct Answer: High concentration gradients
The components of the dialysate treatment that affect clearance includes: Correct Answer:
Dialysate flow, time of treatment, dialyzer size, blood flow rate
Two things that affect the dialyzer's ability to remove wastes from the body include: Correct
Answer: Surface area and molecular weight cutoff
, Dialysate is the fluid that help remove waiste products from the body. It contains a number of
substances. What are the substances that might be prescribed for a dialysate solution? Correct
Answer: Bicarbonate, Sodium, Potassium
What is the most important safety monitor during a dialysis treatment Correct Answer: The
dialysis technician
Dialysate conductivity measures: Correct Answer: The total electrical charge of a solution
Dialysate that has too much sodium may cause patient injury. Too much sodium or
hypernatremia can cause: Correct Answer: Headache, high BP, and shriveling of RBCs
(crenation)
Dialysate that has too much calcium can cause: Correct Answer: Vomiting, confusion,
irritability
Dialysate that has too little sodium can cause: Correct Answer: Low BP, cramping, and bursting
of RBCs (hemolysis)
Things that affect dialysis adequacy are: Correct Answer: -Treatment time
-BFR
-DFR
-Dialyzer clotting/inadequate heparinization
Normal body temp. taken orally is: Correct Answer: 98.6 degrees F
_______ is the instrument use to measure blood pressure Correct Answer: Sphygmomanometer
A rapid pulse of 104 beats/min would indicate that the patient has: Correct Answer: Tachycardia
Seizures during dialysis maybe cause by all of the following EXCEPT:
-Electrolyte imbalance
-Hypotension
-Sudden decrease in dialyzer clearance
-Dialysate composition Correct Answer: Sudden decrease in dialyzer clearance
________ is the normal range for a resting pulse rate in an adult: Correct Answer: 60-100
beats/min.
Which of the following situations will cause an increase in venous pressure during dialysis?
-A clot in the arterial chamber
-A line separation after the dialyzer
-Venous needle infiltration
-Collapsing of the arterial bloodline Correct Answer: Venous needle infiltration
