1. Which organ is primarily responsible for filtering waste
products from the blood?
A. Liver
B. Kidneys
C. Pancreas
D. Spleen
Rationale: The kidneys remove waste, regulate fluid balance,
and maintain electrolyte levels.
Correct Answer: B. Kidneys
2. What is the main purpose of hemodialysis?
A. Increase blood pressure
B. Remove waste and excess fluid from blood
C. Produce red blood cells
D. Improve liver function
Rationale: Hemodialysis replaces kidney function by filtering
toxins and fluid.
Correct Answer: B. Remove waste and excess fluid from blood
,3. Which access site is considered the gold standard for long-
term hemodialysis?
A. Central venous catheter
B. Arteriovenous (AV) fistula
C. Peripheral IV line
D. Intraosseous line
Rationale: AV fistulas have the lowest infection and
complication rates.
Correct Answer: B. Arteriovenous (AV) fistula
4. Which sign indicates infection in a dialysis access site?
A. Cool skin
B. Pale color
C. Redness and warmth
D. Decreased pulse
Rationale: Infection typically presents with redness, warmth,
and sometimes discharge.
Correct Answer: C. Redness and warmth
5. What is the normal range of potassium in adults?
A. 1.0–2.0 mmol/L
B. 2.5–3.0 mmol/L
C. 3.5–5.0 mmol/L
D. 6.0–8.0 mmol/L
,Rationale: Normal serum potassium is 3.5–5.0 mmol/L.
Correct Answer: C. 3.5–5.0 mmol/L
6. Which complication is most associated with high potassium
levels in dialysis patients?
A. Hypoglycemia
B. Cardiac arrhythmia
C. Liver failure
D. Hypertension only
Rationale: Hyperkalemia can cause life-threatening cardiac
arrhythmias.
Correct Answer: B. Cardiac arrhythmia
7. What is the function of heparin during dialysis?
A. Increase blood pressure
B. Prevent clotting in the dialysis circuit
C. Treat infection
D. Increase red blood cells
Rationale: Heparin is an anticoagulant used to prevent clotting
in the extracorporeal circuit.
Correct Answer: B. Prevent clotting in the dialysis circuit
8. What should a technician do first if a patient becomes
hypotensive during dialysis?
, A. Increase ultrafiltration
B. Stop dialysis and notify nurse
C. Give more heparin
D. Restrict oxygen
Rationale: Hypotension requires immediate intervention and
stopping fluid removal.
Correct Answer: B. Stop dialysis and notify nurse
9. Which fluid is commonly used in hemodialysis machines?
A. Saline only
B. Dialysate
C. Plasma
D. Whole blood
Rationale: Dialysate is used to remove toxins and balance
electrolytes.
Correct Answer: B. Dialysate
10. What is the most common cause of end-stage renal
disease (ESRD)?
A. Diabetes mellitus
B. Asthma
C. Tuberculosis
D. Appendicitis
Rationale: Diabetes is the leading cause of ESRD worldwide.
Correct Answer: A. Diabetes mellitus
