Introduction
This comprehensive examination assesses the
hemodialysis registered nurse's clinical judgment and
application of evidence-based nephrology nursing
practice. The assessment integrates DaVita Clinical
Services Policies and Procedures, NNCC certification
standards, and AAMI/CDC guidelines. Multiple-choice and
scenario-based questions evaluate foundational
,knowledge, vascular access management, dialysis
adequacy, complication recognition, infection control, and
patient safety. Candidates must demonstrate the ability
to recognize changes in patient condition, intervene
appropriately, and collaborate within the interdisciplinary
dialysis care team. This test bank supports exam
readiness for the DaVita RN Final Exam and professional
hemodialysis nursing practice.
SECTION ONE: QUESTIONS 1–100
1. During hemodialysis, urea moves from the blood
compartment to the dialysate compartment primarily
through which mechanism?
A. Ultrafiltration
B. Convection
C. Diffusion
D. Osmosis
Correct answer: C
RATIONALE: Diffusion is the primary mechanism for
solute removal in hemodialysis. Urea and other small
molecular weight solutes move across the semipermeable
membrane from an area of higher concentration (blood)
to lower concentration (dialysate) along the concentration
gradient.
2. What is the primary mechanism for fluid removal
during hemodialysis?
,A. Diffusion
B. Osmosis
C. Ultrafiltration
D. Convection
Correct answer: C
RATIONALE: Ultrafiltration is the primary mechanism
for fluid removal during hemodialysis. It involves the
movement of water across the semipermeable membrane
driven by a pressure gradient.
3. A patient requires removal of 3.5 kg of fluid during a
4-hour dialysis treatment. What is the required
ultrafiltration rate?
A. 500 mL/hr
B. 875 mL/hr
C. 1,000 mL/hr
D. 1,200 mL/hr
Correct answer: B
RATIONALE: Ultrafiltration rate calculation: 3.5 kg =
3,500 mL. 3,500 mL ÷ 4 hours = 875 mL/hr. The
ultrafiltration rate should generally not exceed 10-13
mL/kg/hr to minimize intradialytic hypotension and
cramping.
4. Which characteristic best describes a high-flux
dialyzer membrane?
, A. Pore size that allows only small solutes (urea,
creatinine) to pass
B. Increased permeability to middle molecules (β2-
microglobulin, 11,800 Da)
C. Requires lower blood flow rates for equivalent
clearance
D. Cannot be used with standard dialysis machines
Correct answer: B
RATIONALE: High-flux dialyzers have larger pore sizes
and higher hydraulic permeability (KUF >20
mL/hr/mmHg), allowing removal of middle molecules
such as β2-microglobulin in addition to small solutes. This
reduces amyloidosis risk.
5. In countercurrent flow dialysis, blood and dialysate
flow in opposite directions. What is the primary
advantage of this design?
A. Reduces the risk of air embolism
B. Maintains a concentration gradient along the entire
dialyzer length
C. Allows for higher ultrafiltration rates
D. Prevents dialyzer clotting
Correct answer: B
RATIONALE: Countercurrent flow maintains the
steepest possible concentration gradient between blood
and dialysate along the entire length of the dialyzer. If
