RATIONALES (100% CORRECT VERIFIED
SOLUTIONS)
1. What is the primary function of dialysis?
A. Increase blood pressure
B. Remove waste and excess fluid
C. Improve heart rate
D. Increase oxygen levels
Answer: B. Remove waste and excess fluid
Rationale: Dialysis replaces kidney function by removing toxins and excess fluids from the
blood.
2. Which organ is primarily affected in patients requiring dialysis?
A. Heart
B. Liver
C. Kidneys
D. Lungs
Answer: C. Kidneys
Rationale: Dialysis is used when kidneys fail to filter waste effectively.
3. What type of dialysis uses a machine and filter?
A. Peritoneal dialysis
B. Hemodialysis
C. Continuous dialysis
D. Acute dialysis
Answer: B. Hemodialysis
Rationale: Hemodialysis uses a machine to filter blood externally.
4. What is the function of a dialyzer?
A. Pump blood
B. Filter waste
, C. Measure pressure
D. Deliver oxygen
Answer: B. Filter waste
Rationale: The dialyzer acts as an artificial kidney.
5. Which access is commonly used for hemodialysis?
A. IV line
B. AV fistula
C. Arterial catheter
D. PICC line
Answer: B. AV fistula
Rationale: AV fistulas provide long-term vascular access.
6. What is the purpose of dialysate?
A. Carry oxygen
B. Remove toxins
C. Deliver medication
D. Increase BP
Answer: B. Remove toxins

Answer: B. Prevent clotting
Rationale: Heparin prevents blood from clotting in the circuit.
11. Which symptom indicates fluid overload?
A. Dry skin
B. Edema
C. Low BP
D. Weak pulse
Answer: B. Edema
