DaVita RN (2026) | Real Exam
Practice Questions | Graded A+
‣ Your role in anemia management includes: 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: Answer: The diffusion of bicarbonate helps the patient to
achieve acid-base balance by buffering the hydrogen ions.
‣ The transport mechanism when particles move from an area of higher
solute concentration to an area of lower solute concentration is called:
Answer: Diffusion
Convection: solutes dragged across SPM
Osmosis: low to high
‣ TRUE OR FALSE:
Hemodialysis patients are at increased risk of contracting Hepatitis B.
Answer: True, the virus can be transmitted from the use of multidose
drug vials and contamination of medical equipment. Dialysis patients are
immuno-suppressed.
,‣ A common reason how Hepatitis B is transmitted from a patient to a
healthcare worker is: Answer: 1. Penetration of the skin by sharps
2. Contact of blood with broken skin or mucous membranes
‣ If your facility dialyzes Hepatitis B positive patients, which assignment
would NOT be an appropriate patient care assignment? Answer: Caring
for HBsAg and Hepatitis B susceptible patients at the same time
‣ 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: Answer: Gloves, gowns, mask and eye
protection (full face shield or goggles).
‣ Handwashing at a designated clean sink should be performed for a
minimum of: Answer: 20 seconds
‣ Contact transmission is the most important route through which
infections are spread. Contact transmission is defined as: Answer:
Transmission of microorganisms through healthcare workers hands.
‣ Per the CDC, which is the most common factor contributing to
bacteremias in dialysis patients? Answer: The use of catheters for
hemodialysis.
‣ Teammates caring for a patient with active Clostridioides difficile (C-
diff) infection are required to: Answer: Perform frequent hand washing
, with antimicrobial soap, as alcohol-based hand gels may not be effective
to eliminate C. Diff.
‣ To prepare a 1:100 bleach solution, you would Answer: Add 1 part
bleach, 99 parts water.
‣ A 1:10 bleach solution is used to Answer: Clean up visible blood or
gross blood spills
‣ According to Policy and Procedure, gowns: Answer: Must be fully
snapped up (or tied at the neck and waist) and wrists covered.
‣ Why is a "strikethrough" of an external pressure transducer protector of
concern? Answer: 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? Answer: The desired pH range
is 6.9-7.6.
‣ What is the correct procedure for residual bleach testing after chemical
disinfection of distribution loops and equipment fluid pathways?
Answer: Residual bleach testing is performed after bleach disinfectant
and prior to use.
