Sample Questions

Question 1
A hemodialysis machine alarms with a 'blood leak' alert. What is the immediate action?
Stop the blood pump, clamp the blood lines, and do not return blood to the patient until the dialyzer is inspected
Reduce the blood flow rate and observe to see if the alarm clears
Reset the alarm and complete the treatment since false alarms are common
Increase transmembrane pressure to force the leak to seal itself
Question 2
What does a 'conductivity alarm' on a hemodialysis machine indicate?
The dialysate electrolyte concentration is outside safe limits, posing risk of fatal electrolyte imbalance
The blood pump speed has exceeded the prescribed rate
The venous pressure is too high, indicating a possible access occlusion
The heparin infusion pump has run out of medication
Question 3
During a hemodialysis session, the air detector alarm activates. What is the correct response?
Stop the blood pump immediately and clamp the venous line to prevent air from entering the patient
Slow the blood pump to 50 mL/min and watch for visible air bubbles
Reset the alarm and document it as a false alarm
Prime the venous drip chamber with additional heparinized saline while treatment continues
Question 4
What action should a dialysis technician take if a patient's access needle is accidentally dislodged during treatment?
Apply immediate firm pressure to the puncture site, stop the blood pump, and call for emergency assistance
Quickly reinsert the needle and resume treatment to minimize blood loss
Apply a tourniquet above the access site and continue dialysis through the remaining needle
Elevate the affected limb and continue treating with the remaining connected needle
Question 5
A hemodialysis machine displays a 'transmembrane pressure (TMP) high' alarm. What is the most likely cause?
Clotting within the dialyzer fibers, increasing resistance to ultrafiltration
The dialysate temperature is set too high, expanding fluid volume
The patient's blood pressure has dropped below 90 mmHg systolic
The carbon tank has exhausted its chloramine removal capacity
