DaVita Modules(1-4) Exam

Ultrafiltration is defined as:

Controlled fluid removal by manipulation of hydrostatic pressure.

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?

Hypovolemia and hypotensive episodes can cause renal ischemia and can further damage the kidneys.

***The underlying cause of prerenal kidney failure is hypovolemia or poor perfusion. Care must be taken to understand patients who are at high risk.

Your role in anemia management includes:

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:

Helps normalize body pH.

The transport mechanism when particles move from an area of higher solute concentration to an area of lower solute concentration is called:

Diffusion.

Hemodialysis patients are at increased risk for contracting Hepatitis B (T/F):

True.

A common reason of how Hepatitis B is transmitted from a patient to a healthcare worker is:

Needlestick injuries.

Appropriate personal protective equipment (PPE) should be worn whenever there is potential for contact with blood or bodily fluids , hazardous chemicals , contaminated equipment and environmental surfaces PPE includes:

Gloves, gowns, mask and eye protection (full face shield or goggles).

Handwashing at a designated clean sink should be performed for a minimum of:

30 seconds.

Contact transmission is the most important route through which infections are spread. Contact transmission is defined as:

Transmission of microorganisms through healthcare workers hands

Teammates caring for a patient with active Clostridioides difficile (C-diff) infection are required to:

Perform frequent hand washing with antimicrobial soap, as alcohol-based hand gels may not be effective to eliminate C. Diff.

Why is a "strikethrough" of an external pressure transducer protector of concern ?

Fluid could have entered the machine and contaminated the internal pressure transducer protector providing a reservoir for microorganisms and causing subsequent patient blood infections.

What is the safe range for dialysate pH?

Between 6.9 and 7.6

What is the correct procedure for residual bleach testing after chemical disinfection of distribution loops and equipment fluid pathways?

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?

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

To avoid bacterial proliferation ( rapid reproduction ) within the extracorporeal circuit , once primed the recirculation of saline within the dialyzer and blood lines should not exceed ______ prior to initiating the hemodialysis treatment
