During the conversation she states she routinely eats the following foods. Which one is
highest in potassium? - bananas
A reason why a dialysis technician is to be certified is - It's a new Federal regulation

- Clotting of extracorporeal circuit
A teammate asks you to document the normal saline he just gave to Mr. Smith. You would: -
Never document something that someone else did
A true aneurysm can be dangerous because it - May rupture and cause the patient to bleed
profusely

per hour (mL/hr) for her 4 hour treatment? - 1,385 mL/hr
Before a hemodialysis treatment, the technician removes the cap from the fistula needle
and accidentally touches the chair with the tip of the needle. Which of these actions should
the technician take first? - Discard the needle
Dialysate that is too hot will cause - Hemolysis
Dry weight is defined as the - Weight at which the patient has no edema or fluid in the lungs
and BP is normal
During a hemodialysis treatment the technician responds to a low venous pressure alarm.
The most likely cause for this alarm is: - Disconnection of the bloodline
