a. 8 hours
b. 11 hours
c. 14 hours
d. 24 hours

6) The hemodialysis machine continuously monitors many parameters. Which of these parameters must be verified by an external measuring device?

b. Between 6.0 and 6.4
c. Between 7.0 and 7.4
d. Between 8.0 and 8.4

8) Germicide rebound occurs due to:

b. Inadequate dialyzer priming
c. Leaching from the potting compound
d. Residual from the O ring

9) The immediate action for a cracked dialyzer header or a dialyzer blood leak is:
a. Return blood, set-up new dialyzer and lines, reinitiate dialysis.
b. Do not return blood, set-up new dialyzer and lines, reinitiate dialysis.
