1. Which organ system is primarily responsible for filtering waste
products from the blood?
A. Respiratory system
B. Digestive system
C. Renal system
D. Endocrine system
The renal system, specifically the kidneys, filters waste products and
excess fluids from the bloodstream to maintain homeostasis.
2. The primary function of hemodialysis is to:
A. Increase red blood cell production
B. Remove waste and excess fluid from the blood
C. Treat liver disease
D. Replace hormone production
Hemodialysis cleanses the blood by removing toxins, electrolytes,
and excess fluid when the kidneys can no longer perform this
function.
3. Which solution is used in the dialyzer to remove waste by diffusion?
A. Saline
B. Heparin
C. Dialysate
D. Dextrose
, Dialysate is a specially formulated fluid that helps remove waste
products and correct electrolyte imbalances during dialysis.
4. The access site commonly used for long-term hemodialysis is:
A. Central venous catheter only
B. Arteriovenous (AV) fistula
C. Peripheral IV line
D. Urinary catheter
An AV fistula is preferred because it provides reliable blood flow and
has a lower risk of infection.
5. Before initiating dialysis, the technician must first:
A. Start medication infusion
B. Verify patient identity
C. Remove the access needle
D. Adjust dialysate temperature
Verifying patient identity ensures the correct treatment is provided
to the correct individual, preventing serious errors.
6. The normal range for adult blood pressure is approximately:
A. 160/100 mmHg
B. 140/90 mmHg
C. Less than 120/80 mmHg
D. 90/60 mmHg
Blood pressure below 120/80 mmHg is generally considered within
normal limits for healthy adults.
7. Heparin is administered during dialysis to:
A. Lower blood pressure
B. Prevent clotting in the extracorporeal circuit
C. Increase hemoglobin
D. Treat infection
Heparin prevents blood clot formation in the dialysis tubing and
dialyzer.
8. Signs of hypovolemia include:
A. Hypertension and edema
B. Low blood pressure and dizziness
C. Fever and chills
D. Rapid weight gain
, Hypovolemia results from excessive fluid removal and may cause low
blood pressure and dizziness.
9. The most common complication of dialysis is:
A. Stroke
B. Hypotension
C. Fracture
D. Blindness
Hypotension frequently occurs due to rapid fluid removal during
treatment.
10. Proper hand hygiene should be performed:
A. Only before shifts
B. Only after contact with blood
C. Before and after patient contact
D. Once daily
Hand hygiene before and after patient contact reduces the risk of
infection transmission.
11. Which electrolyte imbalance is life-threatening if elevated?
A. Sodium
B. Calcium
C. Potassium
D. Chloride
High potassium levels can cause dangerous cardiac arrhythmias.
12. The dialyzer is also known as the:
A. Pump
B. Artificial kidney
C. Catheter
D. Monitor
The dialyzer functions as an artificial kidney by filtering blood.
13. Normal body temperature is approximately:
A. 35°C
B. 37°C
C. 39°C
D. 40°C
A body temperature around 37°C is considered normal for adults.
