CCHT Exam Review Questions and
Answers Rated A
The functional unit of the kidney, or the structure in the kidney that does the work, is the:
✔✔Nephron
A nephron is made up of: ✔✔A glomerulus and a tubule
The endocrine functions of the kidney includes: ✔✔Making erythropoietin and the active form
of vitamin D
The leading cause of End-Stage Renal Disease for adult in the United States is: ✔✔Diabetes
Patients with kidney failure often complain of itching, which is likely to be caused by:
✔✔Hyperphosphatemia
Why do kidney patients often have bone disease? ✔✔Kidneys stop producing calcitriol
Symptoms that a patient may need more dialysis time include: ✔✔Anorexia, fatigue, swelling
,A semipermeable membrane is a porous barrier that: ✔✔Allow for only certain sized particles to
cross
Diffusion is movement of particles: ✔✔From an area of higher concentration
Negative pressure is pressure created when: ✔✔Fluid is pulled through a restriction
During dialysis, ultrafiltration occurs when: ✔✔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? ✔✔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? ✔✔High concentration gradients
The components of the dialysate treatment that affect clearance includes: ✔✔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: ✔✔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?
✔✔Bicarbonate, Sodium, Potassium
What is the most important safety monitor during a dialysis treatment ✔✔The dialysis technician
Dialysate conductivity measures: ✔✔The total electrical charge of a solution
Dialysate that has too much sodium may cause patient injury. Too much sodium or
hypernatremia can cause: ✔✔Headache, high BP, and shriveling of RBCs (crenation)
Dialysate that has too much calcium can cause: ✔✔Vomiting, confusion, irritability
Dialysate that has too little sodium can cause: ✔✔Low BP, cramping, and bursting of RBCs
(hemolysis)
