CCHT PRACTICE EXAM DAVITA 2023 QUESTIONS
AND ANSWERS
the function unit of the kidney, or the structure in the kidney that does the work,
is the
nephron
the leading cause of chronic kidney disease for adults in the united states:
diabetes
a nephron is made up
a glomerulus and a tubule system
which of the following is not a symptom of uremia
elevated hematocrit
Mrs. smith's dry weight is 62 kg. her pretreatment weight when she came in for
treatment on monday was 67kg. the priming saline amount is 240ml, fluid from
medication is 100 ml , and she is not allowed any fluids during treatment. what is
the total amount of fluid weight to be removed during her treatment?
5,540ml
based on Mrs. smith's total amount of fluids to be removed, what is the
ultrafiltration rate per hour (ml/hr)for her 4-hour treatment?
1,385 ml/hr
which of the following is a cause of hypotension during and after dialysis
treatments?
removing too much fluids
the scale says a patient weights 70 kg. this the same as weighting how many
points (lb)?
154
normal body ph is
7.35-7.45
one sigh and symptoms of fluids overload is
hypertension
abnormal levels of this electrolyte can cause cardiac arrhythmias and even death
potassium
water moves across a membrane from an area of lower solute concentration to an
area of higher solute concentration by which principle
osmosis
waste products are removed during dialysis by which principle
diffusion
excess fluid is forced out of the blood and into the dialysis by which principle
ultrafiltration
the movement of the fluid from the tissue toward a higher concentration of
sodium in the blood is a example of
osmosis
decreasing the patient's prescribed blood flow affects the rate of
diffusion
which of the following actions would increase diffusion during dialysis?
, using a bath that will provide a grater concentration gradient
which of the following diffusion diffuses from the patients blood during dialysis?
urea
ultrafiltration is influenced by
transmembrane pressure
the most common complication in peritoneal dialysis is
peritonitis
the dextrose used in the dialysate for peritoneal dialysis can cause
hyperglycemia
if a patient develops an infection post transplant, the largest contributing factor
would most likely be:
immunosuppressive medication
the most frequent cause of death in the first year post transplant is
infection
total cell volume (TCV) is a indirect measure of the
performance of the dialyzer
the TCV should be no less than
80%
the manimum dwell time to achieve sterilization with the chemical renalin is
11 hours
the reprocessed dialyzer is carefully rinsed prior to patient use to remove
residual sterilant
germicide rebound occurs due to
inadequate dialyzer priming
which organization set the standards and recommendations for dialyzer
reprocessing?
AAMI
the blood path integrity is tested to eliminate the possibility of a blood leak. the
drop in pressure should not exceed:
10 mmhg
the purpose of using counter-current flow is to
increase the rate of waste removal
the total pressure that exists across the dialyzer membrane is called
transmembrane pressure
dialyser ph should be
between 7.0 and 7.4
dialyzer that is too hot will cause
hemolysis
which of the following component in dialysate is used to correct metabolic
acidosis?
bicarbonate
total chlorine levels in the water are tested
before each patient shift or every four hour
the water softener removes
calcium and magnesium
AAMI standars for the total microbial count of dialysate shall not exceed
