DaVita Dialysis Exam Study Questions and
Answers with Rationale 2026/2027
Question 1
Which of the following responsibilities falls under the scope of
practice for a Patient Care Technician rather than a licensed
nurse?
A) Evaluating the extent and severity of patient edema
B) Collecting objective pre-dialysis data such as weight,
temperature, and blood pressure
C) Interpreting abnormal clinical findings and diagnosing
complications
D) Determining clinical scope and nursing care plans
Answer: B
Rationale: Patient Care Technicians are trained to gather factual,
objective parameters while formal clinical assessments and
clinical decision-making are reserved for licensed nurses.
Question 2
Why is it strictly prohibited to manually squeeze an automated
blood pressure cuff to force rapid deflation?
A) It drains the backup battery of the machine
B) It triggers a false blood leak alarm
,C) It damages internal pneumatic valves and sensitive pressure
sensors
D) It causes the blood pump to reverse its rotation
Answer: C
Rationale: Forcing deflation manually places abnormal physical
strain on the machine's internal mechanisms, leading to
equipment failure and inaccurate future readings.
Question 3
What is the primary clinical purpose of medical documentation
in the dialysis setting?
A) To replace verbal shift-to-shift handoff reports entirely
B) To serve as a permanent legal record, ensure continuity of
care, and document treatment responses
C) To calculate the monthly facility revenue and supply
inventory
D) To provide patients with reading material during treatment
Answer: B
Rationale: Accurate charting provides concrete legal proof that
care was rendered according to safety standards and ensures that
all multidisciplinary team members are informed of acute
changes and medications.
Question 4
,What clinical error occurs when drawing a post-dialysis blood
urea nitrogen sample if the blood pump speed is not reduced and
the technician waits only five seconds instead of fifteen
seconds?
A) Cardiopulmonary recirculation artifact leading to a falsely
low post-BUN and an artificially inflated adequacy score
B) Severe hemolysis caused by excessive mechanical shear
stress
C) Complete clotting of the extracorporeal blood circuit
D) Acute dialyzer membrane rupture due to ultrafiltration failure
Answer: A
Rationale: Failing to slow the pump and wait the full duration
allows freshly dialyzed blood returning from the system to mix
with systemic blood yielding an inaccurate level that
overestimates adequacy.
Question 5
Why must patients with chronic kidney disease take prescribed
phosphate binders explicitly with meals and snacks?
A) To stimulate red blood cell production in the bone marrow
B) To chemically bind dietary phosphorus within the
gastrointestinal tract and prevent absorption
C) To neutralize excess stomach acid and prevent gastric ulcers
D) To maintain systemic blood pressure during fluid removal
, Answer: B
Rationale: Phosphate binders must be present in the gut when
food is digested to bind phosphorus thereby preventing
hyperphosphatemia and subsequent bone and mineral disorders.
Question 6
What are the target clinical benchmarks for serum albumin and
normalized protein catabolic rate to monitor patient nutritional
status?
A) Serum albumin less than 2.0 grams per deciliter and
normalized protein catabolic rate less than 0.5 grams per
kilogram per day
B) Serum albumin greater than or equal to 4.0 grams per
deciliter and normalized protein catabolic rate greater than or
equal to 1.0 grams per kilogram per day
C) Serum albumin exactly 3.0 grams per deciliter and
normalized protein catabolic rate of zero
D) Serum albumin between 1.0 and 2.0 grams per deciliter
Answer: B
Rationale: Maintaining these levels helps protect against
protein-energy wasting reducing morbidity and mortality risks in
chronic hemodialysis patients.
