DAVITA RN EXAM SAMPLE TEST 2025/2026 QUESTIONS
WITH ANSWERS GRADED A+
✔✔Monitor weight and blood pressure - ✔✔Keep a little extra fluid on the patient so it is
available to the kidneys when they start filtering/ ultra filtering on their own
✔✔AKI patients are at increased risk of.... - ✔✔Hypovolemia and hypotension
✔✔What is the proportion of dialysate used at Davita? - ✔✔45X
(Mixture of specific proportions of acid, bicarbonate and dialysis quality water)
✔✔2 most frequent physician prescribed potassium strengths of dialysate concentrate
used at Davita? - ✔✔- 2.0 K+
- 3.0 K+
✔✔Which part of the kidney functions similarly to the dialyzer's semi-permeable
membrane to provide filtration and removal of fluid and toxins? - ✔✔Glomerulus
✔✔What are the 2 waste products removed by dialysis that we monitor with monthly
labs? - ✔✔>blood urea nitrogen (BUN)
> creatinine
✔✔How often are dialysis machine alarm tests performed? - ✔✔Before the initiation of
each patient treatment
✔✔The manual conductivity value - ✔✔>Must match +/- 0.4 mS on the Fresenius
(FMC) 2008K and K2 dialysis delivery system displaced conductivity
>Fresenius 2008T and T BlueStar models don't need to check conductivity
>B Braun machine does not require manual conductivity testing but conductivity must
be verified in the 'ENDLF' machine screen
✔✔What is the safe dialysis pH range? - ✔✔Between 6.9 and 7.6
✔✔Why is it important for patient care teammates to know when the water treatment
system disinfection was performed? - ✔✔Because the end to end disinfection process
will also introduce the disinfectant solution to the dialysis delivery systems through their
water inlet lines.
✔✔Following recirculation, how long can a dialyzer and blood lines be set up? - ✔✔2
hours
(Dialyzer and blood lines are not used for dialysis treatment once recirculating for longer
than 2 hours because of the potential for bacterial growth)
, ✔✔What is the correct procedure for residual bleach testing after the chemical
disinfection of loops and equipment fluid pathways? - ✔✔Residual bleach testing should
be performed
>after each disinfection
>prior to equipment use
✔✔OSHA Vs. CMS infection control requirements - ✔✔OSHA: requires employees to
provide workers with a safe workplace
CMS: concerned with patient care and patient safety
✔✔V-tags - ✔✔State specific regulations to be met within a condition (such as infection
control) providing interpretive guidance for each regulation and citing deficiencies by tag
#
✔✔Hand washing technique when caring for a patient with Clostridioides difficile
infection (C-diff) - ✔✔Soap and water only
✔✔Most common infectious complication in hemodialysis patients - ✔✔Bacterial
vascular access infections
✔✔Organism that causes infection in hemodialysis patients most commonly -
✔✔Methicillin- resistant staphylococcus aureus (MRSA) *viable on surfaces for days
>must pay attention to infection control, proper hand hygiene, cleaning and disinfecting
procedures to prevent the spread of infection (viable on surfaces for days)
✔✔Importance of wearing gloves - ✔✔Reduces the risk of hand contamination and
prevents the transfer of organisms already on hands to a patient.
✔✔Why do you need to perform hand hygiene before and after wearing gloves? -
✔✔Gloves are not impervious and have microscopic pores.
✔✔Who can use clean sinks for hand washing? - ✔✔Teammates and patients
✔✔Is a cleaned dialysis machine considered a 'clean' area? - ✔✔No
✔✔How can you tell if an area or sink is clean or dirty in your facility? - ✔✔It is clearly
labeled with a 'clean' or 'dirty' sign
✔✔What is "strike through" of an external pressure transducer and why is it of concern?
- ✔✔> when fluid could have entered the machine and contaminated the internal
pressure transducer protector providing a reservoir for microorganisms
>causing subsequent patient blood infections
