1. What is the primary function of hemodialysis?
A. Deliver nutrients to the blood
B. Remove waste products and excess fluid from the blood
C. Stimulate the immune system
D. Produce red blood cells
Rationale: Hemodialysis is a renal replacement therapy that
helps patients with kidney failure eliminate toxins and excess
fluid.
Correct answer: B
2. Which vascular access type is considered the preferred
long-term access for hemodialysis?
A. Temporary catheter
B. Arteriovenous (AV) fistula
C. Peripherally inserted central catheter (PICC)
D. AV graft
Rationale: AV fistulas have lower infection risk and longer
patency than grafts or catheters.
Correct answer: B
,3. What is the recommended target blood pressure before
initiating dialysis?
A. 90/60 mmHg
B. 120/80 mmHg
C. Patient-specific target as ordered by the nephrologist
D. 160/100 mmHg
Rationale: Blood pressure targets vary per patient; dialysis
initiation should follow individualized orders.
Correct answer: C
4. Which of the following are common complications during
hemodialysis?
A. Hypotension
B. Muscle cramps
C. Fever or chills
D. Hair loss
Rationale: Complications like hypotension, cramps, and fever
are frequently observed; hair loss is not typical during dialysis
sessions.
Correct answer: A, B, C
5. What is the purpose of dialysate in hemodialysis?
,A. To provide oxygen to blood
B. To remove toxins and regulate electrolytes
C. To carry nutrients
D. To prevent blood clotting
Rationale: Dialysate contains a controlled concentration of
electrolytes and bicarbonate to help remove waste and
maintain balance.
Correct answer: B
6. Which of the following lab values are critical to monitor in
dialysis patients?
A. Blood urea nitrogen (BUN)
B. Hemoglobin
C. Serum potassium
D. Liver enzymes
Rationale: BUN, hemoglobin, and potassium directly affect
dialysis safety and efficacy; liver enzymes are less critical for
routine dialysis monitoring.
Correct answer: A, B, C
7. Which of the following are signs of hypotension during
dialysis?
A. Dizziness
B. Nausea
, C. Sweating
D. Increased urine output
Rationale: Hypotension can cause dizziness, nausea, and
diaphoresis; urine output is not typically relevant in patients
with ESRD.
Correct answer: A, B, C
8. What is the recommended action if a patient experiences
severe cramping during dialysis?
A. Increase ultrafiltration rate
B. Stop or reduce fluid removal temporarily
C. Notify the nephrologist
D. Ignore and continue treatment
Rationale: Cramping often results from excessive fluid removal;
adjusting ultrafiltration and notifying the provider is required.
Correct answer: B, C
9. Which of the following is considered standard infection
control for dialysis technicians?
A. Hand hygiene before and after patient contact
B. Use of personal protective equipment (PPE)
C. Reusing disposable gloves without cleaning
D. Proper disinfection of dialysis machines
