SECTION I — DAVITA PCT FINAL EXAMINATION Questions 1 – 103
,1. Ultrafiltration is defined as what process during hemodialysis?
A. Movement of solutes from an area of higher concentration to lower concentration
B. Fluid pushed through the semipermeable membrane by hydrostatic pressure
C. Movement of water from low solute concentration to high solute concentration
D. Exchange of gases across the dialyzer membrane
CORRECT ANSWER B — Fluid pushed through the semipermeable membrane by hydrostatic
pressure
RATIONALE Ultrafiltration is the movement of fluid (water) across the semipermeable
membrane driven by hydrostatic pressure — the pressure gradient between the
blood compartment and the dialysate compartment. This is how excess fluid is
removed from the patient during hemodialysis. Diffusion is solute movement
(higher to lower concentration). Osmosis is water movement toward higher solute
concentration. Convection is solute drag with fluid movement.
2. A patient with acute kidney injury (AKI) dialyzes in the outpatient facility. Why is it
important for patient care teammates to monitor blood pressure and weight closely?
A. To ensure the patient qualifies for transplant sooner
B. Hypovolemia and hypotensive episodes can cause renal ischemia and further damage the
kidneys
C. To determine the patient's insurance coverage eligibility
D. Blood pressure and weight are not particularly important in AKI patients
CORRECT ANSWER B — Hypovolemia and hypotensive episodes can cause renal ischemia and
further damage the kidneys
RATIONALE The underlying cause of prerenal kidney failure is hypovolemia or poor perfusion.
In AKI patients, hypotensive episodes during dialysis can further reduce blood
flow to the already compromised kidneys, causing additional ischemic injury and
potentially converting reversible AKI to irreversible damage. Care must be taken
with patients who are at high risk.
,3. Your role in anemia management includes which of the following?
A. Prescribing erythropoietin-stimulating agents (ESAs)
B. Rinsing back as much of the patient's blood as possible at the termination of each
treatment
C. Administering iron infusions independently
D. Adjusting the patient's ESA dose based on hemoglobin levels
CORRECT ANSWER B — Rinsing back as much of the patient's blood as possible at the
termination of each treatment
RATIONALE The PCT's role in anemia management is to minimize blood loss during dialysis.
Proper rinseback technique at the termination of each treatment returns as much
of the patient's blood as possible, reducing iatrogenic blood loss that contributes
to anemia. Prescribing ESAs, administering iron infusions independently, and
adjusting ESA doses are beyond the PCT scope of practice.
4. During dialysis, what is the physiological benefit of bicarbonate diffusion from the
dialysate into the blood?
A. It increases the patient's potassium levels
B. It helps the patient achieve acid-base balance by buffering hydrogen ions
C. It removes excess glucose from the blood
D. It increases calcium absorption from the dialysate
CORRECT ANSWER B — It helps the patient achieve acid-base balance by buffering hydrogen
ions
RATIONALE Bicarbonate (HCO₃⁻) diffuses from the dialysate into the patient's blood during
dialysis. It acts as a buffer, neutralizing excess hydrogen ions (H⁺) that accumulate
in renal failure due to impaired acid excretion. This correction of metabolic
acidosis is a critical function of hemodialysis. The dialysate bicarbonate
concentration is typically 35–40 mEq/L.
, 5. The transport mechanism when particles move from an area of higher solute
concentration to an area of lower solute concentration is called what?
A. Convection
B. Osmosis
C. Diffusion
D. Ultrafiltration
CORRECT ANSWER C — Diffusion
RATIONALE Diffusion is the passive movement of solute particles from an area of higher
concentration to an area of lower concentration across a semipermeable
membrane. This is the primary mechanism for solute removal (urea, creatinine,
potassium) during hemodialysis. Convection is solute drag with fluid movement.
Osmosis is water movement toward higher solute concentration. Ultrafiltration is
fluid removal by hydrostatic pressure.
6. TRUE OR FALSE: Hemodialysis patients are at increased risk of contracting Hepatitis B.
A. True — the virus can be transmitted from multidose drug vials and contaminated medical
equipment, and dialysis patients are immunosuppressed
B. False — dialysis patients are not at increased risk
CORRECT ANSWER A — True — the virus can be transmitted from multidose drug vials and
contaminated medical equipment, and dialysis patients are
immunosuppressed
RATIONALE TRUE. Hemodialysis patients are at significantly increased risk for Hepatitis B
virus (HBV) infection due to: frequent blood exposure during treatments,
immunosuppressed state from uremia, potential transmission through
contaminated equipment/surfaces, and use of multidose medication vials. This is
why strict infection control, HBV vaccination, and HBsAg screening are mandatory
in dialysis facilities.
