Answers | Graded A+
A technologist notices that a co-worker selects
ex- posure factors for a patient's examination
that are much
higher than indicated by department
protocol or technique charts. The
technologist should:
A) defer to a more senior technologist's
experience and do not say anything.
B)go immediately to the department
supervisor and suggest an investigation.
C)talk to the technologist about why those
expo- sure factors were chosen and express
concern about overexposing the
patient.
D) express concern to other technologists in
the de- partment.
6. Which of the following is FALSE about the laboratory B

A) GFR stands for glomerular filtration rate.
B) GFR is calculated from the results of a blood
urea nitrogen (BUN) test.
C)GFR estimates how much blood passes
through the glomeruli of the kidney.
