QUESTIONS AND
CORRECT VERIFIED
SOLUTIONS
"What happens to diffusion when dialyzer fibers clot? - CORRECT ANSWER=> Clotted fibers cause
the permeability of the fiber to be reduced or eliminated, causing a decrease in treatment
adequacy. As a result , diffusion does not occur as particles cannot diffuse across the
membrane."
"What are the compartments of the dialyzer and what separates them? - CORRECT ANSWER=>
The blood compartment is separated from the dialysate compartment by a semi-permeable
membrane. The blood and dialysate do not mix together."
"What are three types of solutions? - CORRECT ANSWER=> • Hypotonic-containing less particles •
Isotonic-containing equal particles • Hypertonic-containing more particles"
"When is it known that a patient has developed sensitivity to a dialyzer? - CORRECT ANSWER=>
Patients develop mild to severe reactions in some cases, usually seen the first half hour of
treatment. Sneezing, itching, pain at the access site, chest pain, rashing, hives, fever, all may be
symptoms of dialyzer membrane allergy, or allergy to the sterilant used in the manufacturing
process"

, "What volume should be used for fresh fill/run off? - CORRECT ANSWER=> 50 ml of saline should
be drained from the arterial line and 250 ml should be drained from the venous line"
"When dialyzing a patient, what position should the dialyzer be in during hemodialysis? -
CORRECT ANSWER=> Place the dialyzer arterial end up during the treatment."
"What should be checked on a dialyzer before machine set up? - CORRECT ANSWER=> The
dialyzer should be checked for sterility (the dialyzer should either be intact in the original
packaging or if out of the package should have all open ports capped), any structural damage
and be the size and brand that was ordered by the doctor."
"What are electrolytes? - CORRECT ANSWER=> Electrolytes are charged particles that can conduct
an electrical current. Electrolytes in the body control motor, muscle and nerve function, and
maintain the body's homeostasis."
"The most important electrolytes to consider in uremic patients are: - CORRECT ANSWER=>
Sodium (Na+) Potassium (K+) Calcium (Ca++) Magnesium (Mg++)"
"Fluid removed during hemodialysis comes from which body fluid compartment? - CORRECT
ANSWER=> During dialysis fluid is removed from the intravascular fluid compartment or
bloodstream."
"What is dialysate? - CORRECT ANSWER=> Dialysate is a non-sterile solution and its function is to
remove waste products from the blood and balance electrolytes"
"Dialysate is composed of - CORRECT ANSWER=> treated water, acid solution, and bicarbonate
solution"
"What electrolytes are found in the dialysate? - CORRECT ANSWER=> sodium (Na+) potassium
(K+) calcium (Ca++) magnesium (Mg++) chloride (Cl-)"
"What is conductivity? - CORRECT ANSWER=> Conductivity is the ability of a solution to transmit
or "conduct" an electrical current"
"Name four ways dialysate is checked to ensure that it is safe? - CORRECT ANSWER=> pH,
conductivity, monitoring the machine temperature, and a negative residual chlorine (bleach)
after routine (weekly) machine disinfection and before the first treatment after the disinfection"
