Question Title

1. Where in the extracorporeal circuit are you most likely to find a saline infusion line?

Just after the dialyzer

Just before the dialyzer

Just after the blood pump

Just before the blood pump

Question Title

2. How do dialyzers compare to normal, healthy kidneys?

Dialyzers remove more small wastes than healthy kidneys

Dialyzers do not remove as many middle molecules as healthy kidneys

Dialyzers remove more middle molecules than healthy kidneys

Dialyzers can remove anything kidneys can, in similar amounts

Question Title

3. How does a blood leak detector work?

A sensor tests the used dialysate for iron levels

A monitor checks for reduced blood volume

A continuous hemoglobin monitor is used

A light beam is interrupted by red blood cells

Question Title

4. How many compartments does a dialyzer contain?

Thousands and thousands

Two: Red and blue

Two: Blood and dialysate

Two: Blood in and blood out

Question Title

5. In dialysis, how does a Biomedical Technician differ from a Patient Care Technician?

The Biomedical Technician is not a member of the care team

Doing biomedical tasks requires an advanced college degree

Biomedical Technicians work alone and do not report to anyone

Biomedical Technicians work with machines, not with patients

Question Title

6. How can you tell if a dialyzer has a synthetic membrane?

The potting material smells like vinegar when you remove an end cap

There is a red warning label on the cylinder if a membrane is synthetic

Look at the price tag—synthetic membranes are much more costly

Question Title

9. If a dialyzer membrane has a small surface area, how can the nephrologist ensure that more solutes are removed?

Prescribe extra heparin

Prescribe longer treatments

Prescribe a lower blood flow rate

Prescribe a lower dialysate flow rate

Question Title
