If a patient with acute kidney injury (AKI) dialyzes in the outpatient
facility, one task of the patient care teammates is to monitor blood
pressure and weight closely. Why is this important? -
correct answer ✅Hypovolemia and hypotensive episodes can
cause renal ischemia and can further damage the kidneys.

correct answer ✅Rinsing back as much of the patient's blood as
you can at the termination of each treatment.
During dialysis, the movement of bicarbonate from the dialysate
into the blood: -
correct answer ✅Helps normalize body pH.

protector of concern ? -
correct answer ✅Fluid could have entered the machine and
contaminated the internal pressure transducer protector providing

chemical disinfection of distribution loops and equipment fluid
pathways? -
correct answer ✅Residual bleach testing is performed after bleach
disinfectant and prior to use.
Which is a true statement regarding the monitoring , testing , and
verification of conductivity prior to each patient treatment for all
Fresenius machine models and the B Braun system? -
correct answer ✅The B Braun machine conductivity is verified on
the ENDLE machine screen manual conductivity testing with an
independent meter must be within +/-0.4 MS of the theoretical
conductivity TCD for both the B braun and fresenius machines
