Question 6: When would a reused dialyzer be rejected?

• Renalin exposure time was 4 hrs total

2.TCV is 90% of initial volume 3.Applied pressure causes the dialyzer to maintain pressure 4.Visual inspection reveals a few clotted fibers

Renalin exposure time was 4 hrs total

Question 7: Which statements regarding the removal of chlorine & chloramines from water using two carbon tanks is accurate?

1.If sampling reveals there is chloramine in excess of 0.1 ppm leaving the first tank, then water must be sampled after leaving the second tank 2.Sampling must be done to ensure that the carbon tank does not remove too many electrolytes, such as calcium and sodium 3.If a sample from the second tank contains any amount of chloramine, the dialysis session should be cancelled 4.Chlorine and chloramine testing must be done at the beginning of each treatment week

If sampling reveals there is chloramine in excess of 0.1 ppm leaving the first tank, then water must be sampled after leaving the second tank Question 8: A patient is being dialyzed on a machine with Crit-Line Monitor.
