DAVITA RN CORE STUDY GUIDE 2025/2026 QUESTIONS
WITH SOLUTIONS GRADED A+
✔✔If the confirmed result of Total Chlorine testing from the primary carbon filter
indicates a level of greater than 0.1 ppm - ✔✔Testing is performed after the secondary
carbon filter
✔✔If the result of Total Chlorine testing from the primary carbon filter is too high, but
results from the secondary carbon filter are within normal limits - ✔✔Breakthrough Total
Chlorine testing is done every 30 minutes
✔✔Total Water Hardness is checked - ✔✔At the end of the treatment day
✔✔What is the role of the licensed nurse in regards to the Daily Water Treatment Log? -
✔✔The licensed nurse reviews the log for completeness, verifies all parameters are
within specified limits, and initials and signs the log
✔✔What is the purpose of testing the pH of the final dialysate composition? - ✔✔It
verifies that the bicarbonate concentrate has been prepared correctly
✔✔If you have residual acid concentrate from a single gallon container, you should -
✔✔Neutralize it with sodium bicarbonate powder prior to disposal
✔✔The Association for the Advancement of Medical Instrumentation (AAMI) provides
which dialysis quality standards? - ✔✔Dialysis water treatment, dialysis solution
preparation, and dialyzer reprocessing
✔✔today's pre-treatment minus last treatment's post-weight equals? - ✔✔the
Ultrafiltration (UF) goal for the treatment
✔✔today's pre-treatment weight minus the target weight equals: - ✔✔the patient's
interdialytic weight gain
✔✔fluid to be removed plus the total amount of fluid intake during the treatment ( saline,
prime, & rinse-back, oral fluids, IV meds) equals - ✔✔the ultrafiltration (UF) goal for the
treatment
✔✔dividing the patient's UF goal by the ordered treatment hours equals the hourly
ultrafiltration rate (UFR). if the patient's UF goal is 2000 ml(2kg) and she is to dialyze for
4 hours the UFR equals: - ✔✔300ml
✔✔weight gains greater that 5% of target weight are considered excessive. what is a
5% weight gain for a patient weighting 80kg? - ✔✔3kg
, ✔✔to minimize hypertensive episodes, the ordered maximum UFR should not exceed
13 ml/kg/hr. what is the maximum hourly UFR for a patient weighing 65 kg? - ✔✔845 ml
✔✔Linda's target weight is 55 kg, her pre-weight is 58 kg. the amount of fluid weight
Linda gained between treatments is: - ✔✔3 kg=3000 mg= 3000 ml
✔✔in your facility, you add 200 ml for saline prime and 200 ml for rinseback to the UF
goal. This increases Lind's UF goal to: - ✔✔3200 ml
✔✔when observing motor skills, whose responsibility is it to assess the significance of a
complaint or concern? - ✔✔Nurse
✔✔what is a typical temperature for a dialysis patient pre-treatment? - ✔✔97 degree F
✔✔post treatment, you would expect the patients temperature to? - ✔✔decrease
✔✔peripheral vascular disease? - ✔✔systolic leg pressure of more than brachial
systolic pressure may indicate peripheral vascular disease
✔✔bradycardia ( a slow heart rate) - ✔✔can confuse the automated system. in patients
with bradycardia, blood pressures are to be taken manually. deflating the cuff slowly will
provide a more accurate reading
✔✔Arrhythmias ( an irregular heartbeat) means that the cardiac output and therefore
the blood pressure inside the artery may vary significantly from beat to beat. - ✔✔with
the automated oscillometric system, the abnormal pulse may send confusing signals to
the machine'e blood pressure-listening to the sound of the pulse-waves is more
accurate
✔✔In states where a pre-treatment patient assessment is not required, select the best
answer - ✔✔The dialysis technician is to report findings that may preclude treatment
initiation of dialysis to the licensed nurse immediately before initiating the treatment.
✔✔Mrs. Thirsty's target weight is 73kg. Her pre-dialysis weight is 77.8kg. Her last post
weight was 74.2 kg. What is Mrs. Thirsty's UF-goal today (not including prime &
rinseback)? - ✔✔4.8 kg
✔✔Patients presenting to dialysis below their target weight should - ✔✔Be re-weighed
and evaluated for the cause of the weight loss
