Question 1
Blood volume monitoring is an option that gives us more information about which of the
following?
A) The patient's blood pressure and heart rate.
B) The effectiveness of the water treatment system.
C) The hematocrit, change in blood volume, oxygen level, and vascular refill.
D) The conductivity and temperature of the dialysate.
Correct Answer: C) The hematocrit, change in blood volume, oxygen level, and vascular
refill.
Rationale: Blood volume monitoring (BVM) is an advanced tool that provides real-time
data on changes in the patient's blood concentration, helping to assess fluid status, prevent
hypotension, and guide ultrafiltration.
Question 2
In a volumetric ultrafiltration (UF) control system with balancing chambers, each chamber
contains:
A) a different amount of fresh and used dialysate.
B) only fresh dialysate.
C) only used dialysate.
D) the same amount of dialysate.
Correct Answer: D) the same amount of dialysate.
Rationale: Balancing chambers work by precisely measuring and exchanging equal volumes
of fresh dialysate going to the dialyzer and used dialysate coming from the dialyzer, which
allows for accurate control of ultrafiltration.
Question 3
What should your first thought be if you hear a high-pitched bruit, or feel a pounding pulse or
less thrill in an arteriovenous fistula or graft?
A) "The access is developing well and getting stronger."
B) "I'd better ask the nurse to check for stenosis."
,C) "The patient's blood pressure must be very high today."
D) "This means the blood flow is too low."
Correct Answer: B) "I'd better ask the nurse to check for stenosis."
Rationale: Changes in the sound (bruit) and feel (thrill) of an access are key indicators of a
problem. A high-pitched sound or a pounding pulse often suggests a narrowing (stenosis) in
the vessel, which requires medical evaluation.
Question 4
How does a good blood rinseback after dialysis make reprocessing of the dialyzer easier?
A) It sterilizes the dialyzer fibers.
B) It tests the dialyzer for leaks.
C) It leaves less chance of clotting, which is hard to clean out.
D) It measures the total cell volume of the dialyzer.
Correct Answer: C) It leaves less chance of clotting, which is hard to clean out.
Rationale: Effective rinseback removes as much blood as possible from the dialyzer. Any
remaining blood can clot, and these clots are difficult to remove during reprocessing and
can block fibers, reducing the dialyzer's effectiveness for the next use.
Question 5
Giving patients intravenous saline or hypertonic saline to treat cramping can increase the risk of
which of the following?
A) Hypokalemia
B) Sodium loading
C) Hypotension
D) Anemia
Correct Answer: B) Sodium loading
Rationale: Both normal saline and hypertonic saline contain sodium. Administering these
solutions increases the patient's total sodium level, which can lead to increased thirst, large
interdialytic weight gains, and hypertension.
Question 6
Osmolality refers to:
A) The pH of a solution.
, B) The temperature of a solution.
C) How many total solutes are in a solution.
D) The electrical conductivity of a solution.
Correct Answer: C) How many total solutes are in a solution.
Rationale: Osmolality is a measure of the total concentration of all dissolved particles
(solutes) in a solution. In dialysis, it influences the movement of water across the dialyzer
membrane.
Question 7
Who will be in charge if a disaster affects your clinic?
A) The first person to arrive at the clinic.
B) The most senior patient.
C) The medical director, regardless of their location.
D) Someone who has been designated for that role during disaster planning.
Correct Answer: D) Someone who has been designated for that role during disaster
planning.
Rationale: Effective disaster response relies on a pre-established plan, which includes a clear
chain of command. A specific person is designated as the incident commander to manage
the response.
Question 8
How does an "action level" for a substance in the water relate to its maximum allowable level?
A) Action levels are always higher.
B) Action levels are always lower.
C) Action levels are the same as the maximum level.
D) Action levels only apply to chlorine.
Correct Answer: B) Action levels are always lower.
Rationale: An action level is a threshold that is set lower than the maximum allowable limit.
Reaching the action level triggers a requirement to take corrective action to prevent the
level from reaching the unsafe maximum.
Question 9
How do Medicare and an employer group health plan (EGHP) coordinate benefits for a dialysis
