Fresenius Clinical Annual Competency Exam - Version 2
Comprehensive Practice Question Bank (150 Questions)
Target Audience: Dialysis Technicians, Patient Care Technicians (PCTs), Registered Nurses, and
Clinical Staff at Fresenius Medical Care (FMC) facilities
Difficulty Level: Mixed (Fundamental to Advanced/Scenario-Based)
Topics Covered: Hemodialysis Principles & Procedures, Water Treatment & Quality Standards,
Vascular Access Management, Infection Prevention & Control, Medication Administration,
Emergency Response & Complication Management, Machine Operation & Troubleshooting,
Regulatory Compliance & Documentation, Patient Safety & Assessment
SECTION 1: PATIENT SAFETY & ASSESSMENT (Questions 1–20)
Question 1
A patient undergoing hemodialysis complains of sudden shortness of breath, headache, and
reports a burning sensation at the needle site. The blood in the dialyzer appears bright cherry
soda-colored. What is the most appropriate immediate action?
A) Increase the blood flow rate to flush the circuit
B) Stop the blood pump and do not return blood to the patient
C) Administer normal saline bolus and continue treatment
D) Decrease the ultrafiltration rate
Correct Answer: B
Rationale: Bright cherry soda-colored blood with shortness of breath, headache, and burning
at the needle site are classic signs of hemolysis. The blood pump must be stopped and blood
should not be returned to the patient to prevent hyperkalemia and further complications.
Question 2
Several patients with normal pre-dialysis temperatures develop sudden chills and a spike in
,temperature during treatment. This situation is most likely caused by:
A) Inadequate heparinization
B) Presence of endotoxins in the dialysate
C) Air embolism
D) Hypotension
Correct Answer: B
Rationale: Endotoxins in the dialysate can cause pyrogenic reactions characterized by sudden
chills, fever, and hypotension in multiple patients simultaneously.
Question 3
What is the recommended frequency for testing total chlorine in dialysis water when no patient
sessions are scheduled?
A) Every 2 hours
B) Every 4 hours
C) Every 6 hours
D) Every 8 hours
Correct Answer: B
Rationale: When no patient sessions are scheduled, total chlorine testing should be carried out
approximately every 4 hours during operation.
Question 4
A patient presents with a pulse rate of 44 bpm but does not appear to be in distress. What
should be the dialysis technician's immediate action?
A) Begin treatment as scheduled
B) Notify the RN immediately
C) Administer atropine
D) Check the patient's blood pressure only
,Correct Answer: B
Rationale: Bradycardia (pulse < 60 bpm) requires immediate nursing assessment. The
technician should notify the RN for further evaluation before proceeding with treatment.
Question 5
According to Fresenius policy, what is the maximum allowable level for total chlorine in dialysis
water?
A) 0.01 mg/L
B) 0.05 mg/L
C) 0.10 mg/L
D) 0.50 mg/L
Correct Answer: C
Rationale: The maximum allowable level for total chlorine in dialysis water is 0.10 mg/L. Higher
levels can cause hemolysis in patients.
Question 6
If a safety check reveals that the Hemosafe clamp is secured on the arterial line rather than the
venous line, this indicates:
A) Correct placement
B) An intervention is needed
C) No action is required
D) The machine is functioning properly
Correct Answer: B
Rationale: The Hemosafe clamp should be secured on the venous line. If found on the arterial
line, this indicates improper placement requiring immediate correction.
, Question 7
Routine post-dialysis treatment documentation on the patient's dialysis treatment record
should include the patient's:
A) Blood pressure and temperature only
B) Blood pressure and temperature both post-reinfusion and prior to disconnection
C) Weight only
D) Laboratory results only
Correct Answer: B
Rationale: Routine post-dialysis treatment documentation must include the patient's blood
pressure and temperature both post-reinfusion and prior to disconnection.
Question 8
What is the primary function of Renin in the body?
A) Lower blood pressure
B) Raise blood pressure
C) Regulate blood glucose
D) Stimulate red blood cell production
Correct Answer: B
Rationale: Renin is an enzyme released by the kidneys that raises blood pressure through the
renin-angiotensin-aldosterone system.
Question 9
A patient complains of pain at the catheter exit site. What should the PCT do first?
A) Administer pain medication
B) Notify the RN
C) Clean the site with alcohol
D) Document the complaint
