Introduction
This comprehensive practice examination is designed to assess the knowledge,
clinical judgment, and decision-making skills essential for a DaVita Patient Care
Technician. The exam covers a wide range of topics, including core patient care,
hemodialysis procedures, vascular access management, infection control, water
treatment, and emergency response. Through a blend of foundational theory and
applied scenario-based multiple-choice questions, candidates will demonstrate their
readiness to provide safe, effective, and compassionate care in a dialysis setting. A
thorough understanding of regulatory compliance, ethical standards, and patient
communication is critical. All questions are structured to mirror real-world
challenges, ensuring the exam is a true test of practical competence and
professional readiness.

SECTION ONE: QUESTIONS 1 – 50
═══════════════════════════════════════════
1. Which of the following is the primary function of the kidneys in relation to
dialysis treatment?
A. Regulation of blood pressure
B. Production of erythropoietin
C. Filtration of waste products and excess fluid
D. Activation of vitamin D
🟢 Correct Answer: C. Filtration of waste products and excess fluid
🔴 Explanation: The primary function of the kidneys is to filter waste products like
urea and creatinine and excess fluid from the blood. While the kidneys do play a
role in blood pressure regulation, erythropoietin production, and vitamin D
activation, the main focus of dialysis is to artificially perform the filtration
function.
2. A patient’s predialysis lab results show a potassium level of 6.8 mEq/L. Which
of the following actions should the PCT prioritize?
A. Prepare the patient for their dialysis treatment as scheduled
B. Immediately report the finding to the registered nurse
C. Instruct the patient to eat a banana to counterbalance the level
D. Recheck the labs on the next shift
🟢 Correct Answer: B. Immediately report the finding to the registered nurse
🔴 Explanation: A potassium level of 6.8 mEq/L is critically high and poses a life-
threatening risk of cardiac arrhythmias. The PCT must report this critical value to
the RN immediately to ensure prompt intervention, such as emergency dialysis or
medication administration.
,3. What is the standard recommended blood flow rate for a typical adult
hemodialysis patient?
A. 100-150 mL/min
B. 200-250 mL/min
C. 300-450 mL/min
D. 500-600 mL/min
🟢 Correct Answer: C. 300-450 mL/min
🔴 Explanation: The standard adult hemodialysis blood flow rate typically ranges
from 300 to 450 mL/min. This range is effective for achieving adequate clearance
while minimizing the risk of damaging the vascular access. Lower rates may be
used for pediatric or unstable patients.
4. While assessing a patient’s AV fistula, you palpate a thrill and auscultate a
bruit. This indicates:
A. An aneurysm is forming in the fistula
B. The fistula is clotted and not patent
C. Adequate blood flow is present within the fistula
D. There is a severe stenosis in the vessel
🟢 Correct Answer: C. Adequate blood flow is present within the fistula
🔴 Explanation: A thrill (palpable vibration) and bruit (audible swooshing sound)
are the hallmark signs of a healthy, patent AV fistula with adequate blood flow.
The absence of these signs would indicate a potential thrombosis or stenosis.
5. What is the primary purpose of using a germicidal solution like Renalin in a
hemodialysis machine during disinfection?
A. To eliminate biofilm and bacterial contamination
B. To increase the conductivity of the dialysate
, C. To remove calcium and magnesium deposits
D. To lubricate the internal components of the machine
🟢 Correct Answer: A. To eliminate biofilm and bacterial contamination
🔴 Explanation: Germicidal solutions like Renalin are used for the chemical
disinfection of the hemodialysis machine. Their primary purpose is to destroy
microorganisms and prevent the formation of biofilm, which can lead to patient
infections and pyrogenic reactions.
6. A new patient asks why their urine output is decreasing. The best response
by the PCT is:
A. "It’s normal; your body is just making less urine because of your age."
B. "This means your medications are working and are the sole reason for this
change."
C. "As your kidneys fail, they lose the ability to produce urine, so your body holds
onto more fluid."
D. "Don't worry; it's because the dialysis machine is now doing the work of your
kidneys."
🟢 Correct Answer: C. "As your kidneys fail, they lose the ability to produce urine,
so your body holds onto more fluid."
🔴 Explanation: The PCT should provide a simple, accurate, and empathetic
explanation. As End Stage Renal Disease (ESRD) progresses, the nephrons fail,
leading to a decrease in glomerular filtration rate (GFR) and therefore decreased
urine output. The patient is not making less urine because the dialysis machine is
doing the work, but because their kidneys are failing.
7. Which of the following is a correct step in preparing the dialysis machine for
a patient?
