1. A dialysis technician’s primary responsibility during hemodialysis
treatment is to:
A. Diagnose kidney disease
B. Prescribe medications
C. Monitor and assist with dialysis treatment according to prescribed
orders
D. Perform kidney transplantation
Answer: C
Rationale: Dialysis technicians are responsible for preparing, monitoring,
and maintaining dialysis treatments while following physician orders and
facility protocols.
2. Which organ is primarily affected in patients requiring dialysis?
A. Liver
B. Kidney
C. Pancreas
D. Spleen
,Answer: B
Rationale: Dialysis is performed when the kidneys can no longer
adequately remove waste products and excess fluid from the blood.
3. The process of removing waste products and excess fluid from the
blood through an artificial membrane is called:
A. Ventilation
B. Filtration
C. Hemodialysis
D. Perfusion
Answer: C
Rationale: Hemodialysis uses a dialyzer and semipermeable membrane to
remove waste products and excess fluid from the bloodstream.
4. Which vascular access is generally preferred for long-term
hemodialysis?
A. Central venous catheter
B. Peripheral IV
C. Arteriovenous fistula
D. PICC line
Answer: C
Rationale: An arteriovenous fistula has the lowest infection rate and
longest lifespan among vascular access options.
5. Before initiating dialysis treatment, the technician should first:
A. Administer medications
B. Verify the patient’s identity
C. Remove needles
D. Disconnect the dialyzer
Answer: B
,Rationale: Patient identification is a critical safety step that helps prevent
treatment errors and ensures correct care delivery.
6. The dialyzer is often referred to as the:
A. Artificial kidney
B. Blood pump
C. Access port
D. Catheter hub
Answer: A
Rationale: The dialyzer performs filtration functions similar to those of
healthy kidneys.
7. Diffusion during dialysis refers to:
A. Movement of water by pressure
B. Movement of solutes from high concentration to low concentration
C. Blood clot formation
D. Fluid overload
Answer: B
Rationale: Diffusion allows waste products to move across a
semipermeable membrane from higher to lower concentrations.
8. Ultrafiltration primarily removes:
A. Potassium
B. Protein
C. Excess fluid
D. Calcium
Answer: C
Rationale: Ultrafiltration uses pressure gradients to remove excess fluid
from the patient's bloodstream.
, 9. A common symptom of hypotension during dialysis is:
A. Increased appetite
B. Dizziness
C. Hyperactivity
D. Polyuria
Answer: B
Rationale: Low blood pressure may cause dizziness, weakness, nausea, and
lightheadedness during treatment.
10. Which electrolyte is most closely monitored in dialysis patients
due to the risk of cardiac complications?
A. Magnesium
B. Sodium
C. Potassium
D. Chloride
Answer: C
Rationale: Abnormal potassium levels can lead to serious cardiac
arrhythmias and require close monitoring.
11. The purpose of heparin during dialysis is to:
A. Lower blood pressure
B. Prevent clotting in the extracorporeal circuit
C. Increase urine output
D. Reduce infection
Answer: B
Rationale: Heparin is an anticoagulant used to prevent clot formation
within the dialysis circuit.
12. Which condition is a common cause of end-stage renal disease?
A. Asthma
