Section 1: Hemodialysis Basics & Equipment (Fresenius 2008 Series Machines)
Q1: You're reviewing the treatment parameters on a Fresenius 2008T before your patient
arrives. For a routine treatment using a well-functioning AV fistula, which venous
pressure range would you expect to see once the patient is hooked up and running
smoothly?
A. 10–50 mmHg
B. 50–250 mmHg
C. 250–400 mmHg
D. 400–600 mmHg [CORRECT]
Correct Answer: B
Rationale: The best answer is B. With a properly functioning AV fistula, you typically see
venous pressures running between 50 and 250 mmHg on a Fresenius machine.
Pressures much lower or higher than that usually point to an access or line issue that
needs troubleshooting.
Q2: Your biomedical team just calibrated the conductivity monitor on your 2008K2.
When you're programming the prescription for standard bicarbonate dialysis, what
conductivity range should you typically be aiming for?
A. 8.0–10.0 mS/cm
B. 10.5–12.5 mS/cm
C. 13.5–14.5 mS/cm [CORRECT]
D. 16.0–18.0 mS/cm
Correct Answer: C
,Rationale: This choice is correct because Fresenius machines are usually programmed
with a conductivity range of 13.5 to 14.5 mS/cm for standard bicarbonate dialysis. That
range gives you the right electrolyte balance in the dialysate.
Q3: Mrs. Garcia is on a heparin protocol for her treatment today. Her baseline ACT
before heparin was 135 seconds. After the loading dose and thirty minutes of infusion,
you draw an ACT. What target range tells you her anticoagulation is where it needs to
be?
A. 80–120 seconds
B. 120–160 seconds
C. 150–220 seconds [CORRECT]
D. 250–300 seconds
Correct Answer: C
Rationale: The best answer is C. When you're monitoring ACT for heparin therapy during
dialysis, you're generally looking to keep it around one-and-a-half to two times the
patient's baseline, which puts most folks in that 150 to 220 second range.
Q4: You're in the middle of a treatment when the arterial pressure alarm on your
Fresenius 2008T starts sounding. The display is reading −220 mmHg. What's the first
thing you should check?
A. The venous line for kinks or obstruction
B. The arterial needle position and the bloodline connections for kinks [CORRECT]
C. The dialysate conductivity setting
D. The patient's blood pressure cuff
Correct Answer: B
Rationale: This choice is correct because a low arterial pressure reading usually means
the blood pump is having trouble pulling blood from the access. You want to look at the
arterial needle first—make sure it hasn't slipped against the vessel wall or that the line
isn't kinked somewhere between the patient and the machine.
Q5: The air detector alarm suddenly goes off on your machine during treatment. You
look up and see a little foam in the venous drip chamber. What's your very first move?
A. Clamp the venous bloodline immediately [CORRECT]
B. Increase the blood pump speed to push the air through faster
C. Silence the alarm and keep watching
, D. Check the dialysate flow rate
Correct Answer: A
Rationale: The best answer is A. When that air detector goes off, your first job is patient
safety. Clamping the venous line stops any air from getting back toward the patient
while you figure out where the air is coming from.
Q6: During treatment, the blood leak detector alarm sounds on your Fresenius machine.
The dialysate effluent line looks pink-tinged. What does this tell you, and what should
you do?
A. The dialyzer membrane has likely ruptured; stop the blood pump and do not return
blood to the patient [CORRECT]
B. There's air in the dialysate; continue treatment and increase dialysate flow
C. The conductivity is too low; check the acid concentrate
D. The venous pressure is too high; check for clotting
Correct Answer: A
Rationale: This choice is correct because the blood leak detector is telling you there's
blood where it shouldn't be—in the dialysate compartment. That almost always means
the dialyzer membrane has ruptured, and you need to stop the blood pump and take the
patient off without returning blood.
Q7: A new traveler asks you what the standard dialysate flow rate is on most Fresenius
machines when you're running a typical prescription. What do you tell them?
A. 300 mL/min
B. 500–800 mL/min [CORRECT]
C. 1000 mL/min
D. 1200 mL/min
Correct Answer: B
Rationale: The best answer is B. Most Fresenius machines run a dialysate flow rate
somewhere between 500 and 800 mL per minute, with 500 being pretty standard unless
the prescription calls for something higher.
Q8: You're priming a new dialyzer on the 2008T and notice a small pocket of air trapped
in the venous header that won't seem to clear with the saline prime. What's the best way
to handle this?
A. Gently tap the header while continuing the saline prime [CORRECT]
