DaVita PCT Exam Questions and Verified
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 action must a Patient Care Technician take immediately if
a water hardness test performed on a soft water effluent sample
exceeds acceptable limits?
A) Ignore the result if the municipal water pressure is high
B) Inspect the water softener salt levels, regenerate the softener
tank, and retest before allowing water to enter the reverse
osmosis system
C) Turn off the carbon adsorption tanks immediately
D) Increase the dialysis machine blood pump speed
Answer: B
Rationale: High water hardness indicates softener exhaustion,
which can ruin downstream reverse osmosis membranes and
cause scaling if not addressed promptly.
Question 5
During a power failure requiring manual blood return via the
hand crank, what is the operator's most critical safety priority?
A) Speeding up the hand crank to finish the return in under two
minutes
B) Maintaining continuous visual monitoring of the
extracorporeal circuit to prevent air embolism
C) Turning off the water treatment system immediately
D) Documenting the exact outdoor temperature on the flow
sheet
, Answer: B
Rationale: Hand cranking bypasses automated electronic air-
detector safety clamps placing the patient at immediate risk of
air entry if lines are not carefully watched.
Question 6
An unexpected and sudden rise in venous pressure during
hemodialysis is most commonly caused by what condition?
A) A loose arterial blood tubing connection before the blood
pump
B) An obstruction downstream from the pressure monitor such
as a kinked blood line or clotted drip chamber
C) A completely empty saline bag attached to the arterial line
D) Low dialysate flow rate through the dialyzer
Answer: B
Rationale: Any physical resistance or blockage downstream
creates backpressure that registers as an elevated reading on the
venous pressure monitor.
Question 7
What immediate action must be taken if a venous needle
infiltrates during dialysis treatment?
A) Increase the blood pump speed to clear the remaining blood
from the lines
