DAVITA PCT FINAL EXAM ACTUAL EXAM 2026 | 2 DIFFERENT VERSIONS | ALL EXAM
QUESTIONS AND CORRECT ANSWERS (ALREADY GRADED A+) | LATEST VERSIONS
Question 1
What factor would influence the "t" of the Kt/V formula?
A) Using a larger surface area dialyzer
B) Inadequate heparinization during treatment
C) Shortened treatment time
D) Increasing the dialysate flow rate
E) Reducing the blood pump speed
Correct Answer: C) Shortened treatment time
Rationale: In the Kt/V formula for dialysis adequacy, "K" represents dialyzer clearance,
"V" represents the patient's volume of urea distribution (body water), and "t" represents
total treatment time. Any premature termination, machine interruption, or early sign-off
shortens total treatment time ("t"), which directly decreases the overall delivered dose of
dialysis.
Question 2
Poor wound healing in hemodialysis patients is directly related to which nutritional deficit?
A) Excessive phosphorus intake
B) Inadequate protein intake
C) Insufficient dietary sodium
D) Low carbohydrate consumption
E) Elevated serum calcium
Correct Answer: B) Inadequate protein intake
Rationale: Dialysis patients lose amino acids and small peptides across the semipermeable
membrane during every treatment. Protein is essential for tissue repair, immune response,
and cellular synthesis; therefore, inadequate dietary protein intake directly causes poor
wound healing and protein-energy wasting.
Question 3
A standing post-treatment blood pressure reading is considered an abnormal finding when it
meets which criteria?
A) Systolic blood pressure between 110 and 130 mmHg
B) Diastolic blood pressure between 60 and 80 mmHg
C) Systolic blood pressure greater than 140 mmHg or less than 90 mmHg
D) Systolic blood pressure exactly equal to the sitting reading
E) Heart rate between 60 and 90 beats per minute
Correct Answer: C) Systolic blood pressure greater than 140 mmHg or less than 90 mmHg
Rationale: Clinical safety guidelines designate a standing post-dialysis systolic blood
pressure of greater than 140 mmHg (hypertension) or less than 90 mmHg
(hypotension/orthostasis) as an abnormal finding that must be reported to the licensed
nurse before the patient is cleared for discharge.

Question 4
What factor would decrease the "K" in the Kt/V formula?
A) Increasing treatment time by thirty minutes
B) Inadequate anticoagulation leading to dialyzer clotting
C) Utilizing a dialyzer with a larger surface area
D) Increasing blood flow rate to 450 mL/min
E) Correcting needle site recirculation
Correct Answer: B) Inadequate anticoagulation leading to dialyzer clotting
Rationale: "K" represents urea clearance. If heparinization is inadequate and fibers within
the dialyzer clot off, the effective semipermeable surface area available for diffusion is
reduced, leading to a marked decrease in dialyzer clearance ("K").
Question 5
What is the primary clinical purpose of documentation in the electronic health record?
A) To justify equipment purchasing budgets
B) Provides data for the continuity and planning of patient care
C) To record personal opinions about client adherence
D) To avoid having to verbally communicate with teammates
E) To schedule staff lunch breaks
Correct Answer: B) Provides data for the continuity and planning of patient care
Rationale: Timely, accurate, and objective documentation in the medical record creates an
ongoing legal and clinical account of treatment delivery. It ensures safe continuity of care,
allows the interdisciplinary team to track treatment trends, and supports coordinated
clinical decision-making.
Question 6
Per physician order and based on individual patient needs, Chronic Kidney Disease Mineral and
Bone Disorder (CKD-MBD) is primarily managed with which combination of therapies?
A) Phosphate binders, vitamin D, and Calcitriol
B) Potassium binders, loop diuretics, and normal saline
C) Erythropoietin, intravenous iron, and folic acid
D) Broad-spectrum antibiotics and corticosteroid therapy
E) Heparin, sodium bicarbonate, and hypertonic dextrose
Correct Answer: A) Phosphate binders, vitamin D, and Calcitriol
Rationale: CKD-MBD disrupts calcium, phosphorus, parathyroid hormone (PTH), and
active vitamin D balance. Nephrologists prescribe phosphate binders to limit dietary
phosphorus absorption in the gut alongside active vitamin D sterols (such as calcitriol,
paricalcitol, or doxercalciferol) to suppress secondary hyperparathyroidism.
Question 7
What is the most likely cause of a false blood leak detector alarm occurring during the
, 3
recirculation of the extracorporeal circuit?
A) Rupture of dialyzer hollow fibers
B) Air bubbles in dialysate or a dirty sensor
C) High transmembrane pressure
D) Elevated venous line pressure
E) Clotting in the arterial header
Correct Answer: B) Air bubbles in dialysate or a dirty sensor
Rationale: The optical blood leak detector relies on a beam of light passing through the
effluent dialysate stream. Optical interference caused by micro-air bubbles traversing the
chamber or dried mineral deposit/debris coating the sensor lens will trigger a false blood
leak alarm.
Question 8
Who is the designated person responsible for the implementation, adherence, and training of
clinical policies and procedures within the facility?
A) The Biomedical Technician
B) The Facility Administrator (FA)
C) The Medical Social Worker
D) The Registered Dietitian
E) The Lead Patient Care Technician
Correct Answer: B) The Facility Administrator (FA)
Rationale: The Facility Administrator (FA) is administratively responsible for the daily
operation of the center, ensuring teammates follow established clinical policies, complete
required training, and maintain continuous survey readiness.
Question 9
What must the patient care teammate do during the administration of an intravenous normal
saline bolus to a patient?
A) Leave the station to retrieve other medication doses
B) Turn off the blood pump and step away for five minutes
C) The teammate must remain with the patient to monitor the process until administration is
complete and lines are secure
D) Delegate observation of the saline infusion to a family member
E) Clamp the venous bloodline completely during the entire bolus
Correct Answer: C) The teammate must remain with the patient to monitor the process
until administration is complete and lines are secure
Rationale: To prevent catastrophic air embolism, rapid fluid overload, or accidental line
separation, the clinical teammate administering normal saline must remain at the bedside
with their eyes on the patient, bloodlines, and saline bag until the infusion is concluded and
clamps are secured.
