DOMAIN I: CLINICAL (48-52%)
Section A: Vascular Access Assessment and Cannulation
Question 1
A hemodialysis technician is assessing a patient's arteriovenous (AV) fistula prior to cannulation.
Which finding requires immediate notification of the registered nurse?
A) A palpable thrill over the entire fistula
B) An audible bruit with a continuous whooshing sound
C) A pulsatile mass with a distinct systolic bruit
D) A visible bulge that flattens when the arm is elevated
- detailed answer 100% correct :- C
Rationale: A pulsatile mass with a distinct systolic bruit is indicative of a pseudoaneurysm or
aneurysm formation, which increases the risk of rupture and hemorrhage.A normal AV fistula
should have a palpable thrill and a continuous (not systolic) bruit. A bulge that flattens with
elevation is normal venous distension. The technician must report abnormal findings
immediately to prevent life-threatening complications.

Question 2
During the "look, listen, feel" assessment of an AV graft, the technician notes the absence of a
thrill but presence of a high-pitched bruit. What is the most appropriate interpretation?
A) Normal findings for a mature graft
B) Possible outflow stenosis
C) Complete graft thrombosis
D) Adequate arterial inflow
- detailed answer 100% correct :- B
Rationale: A high-pitched bruit without a palpable thrill suggests outflow stenosis, where
turbulent flow creates an abnormal sound but flow volume is insufficient to generate a
thrill.Complete thrombosis would present with neither thrill nor bruit. Normal findings include
both thrill and bruit. The technician should report this finding immediately as stenosis can
progress to thrombosis and access failure.
Question 3
A technician is preparing to cannulate a patient's AV fistula using the buttonhole technique.
Which of the following is a critical requirement for buttonhole cannulation?
A) The same cannulator must perform all cannulations
B) A new site must be used for each cannulation
C) Blunt needles must be used after track formation
D) The access must be at least 1 year old
- detailed answer 100% correct :- C
Rationale: Buttonhole cannulation requires the use of blunt needles after the track has been
established (typically after 6-10 consecutive cannulations with sharp needles at the same
site).Blunt needles prevent damage to the established track and reduce the risk of infiltration.
Sharp needles should never be used once the track is formed. The same cannulator is
recommended but not an absolute requirement, and the access does not need to be 1 year
old—maturity is determined by clinical assessment.
Question 4
A patient with a central venous catheter (CVC) presents with fever, chills, and erythema at the
exit site. The technician should:
, 4
A) Continue the treatment as scheduled
B) Notify the nurse immediately and prepare for possible catheter removal
C) Apply topical antibiotic ointment and proceed
D) Flush the catheter with heparinized saline
- detailed answer 100% correct :- B
Rationale: Fever, chills, and exit site erythema are signs of a catheter-related bloodstream
infection (CRBSI) .The technician must notify the registered nurse immediately. Catheter-related
infections are a leading cause of morbidity in hemodialysis patients and often require catheter
removal and systemic antibiotics.Continuing treatment, applying topical antibiotics, or flushing
the catheter would delay appropriate care and potentially worsen the infection.
Question 5
Which of the following is the preferred vascular access for long-term hemodialysis?
A) Arteriovenous graft
B) Arteriovenous fistula
C) Tunneled central venous catheter
D) Non-tunneled central venous catheter
- detailed answer 100% correct :- B
Rationale: The arteriovenous (AV) fistula is the preferred vascular access for long-term
hemodialysis due to its superior patency rates, lower infection risk, and fewer complications
compared to grafts and catheters.AV grafts have higher thrombosis rates, and catheters carry
the highest risk of infection and stenosis. The AV fistula is considered the "gold standard" for
vascular access.
Question 6
During cannulation of an AV fistula, the technician obtains bright red, pulsatile blood return.
What should the technician do?
A) Continue cannulation as planned
B) Remove the needle and apply firm pressure immediately
C) Flush the needle with saline and proceed
D) Advance the needle further into the vessel
- detailed answer 100% correct :- B
