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

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

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
