DAVITA CCHT PRACTICE EXAM QUESTIONS AND ANSWERS ( GRADED A+) 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 - 200 CFU/ML the water softener - operates on the principle of ion exchange which of the following is considered to be safe water for dialysis - dialysis quality water patient expose to chloramines during the hemodialysis treatment may cause - hemolysis according to AAMI the standard levels for endotoxin levels is - less than two (2) EU/ML. feed conductivity- product conductivity divided by x 100 is the formula calculation of - percent rejection a mixed-bed DI tank contains - cations and anions the substance that may be added to the municipal drinking water to make it clearer is - aluminum AAMI chemical analysis of water used for hemodialysis is tested - annually the part of the cell wall of bacteria that, when released, can cause fever in hemodialysis patients is - endotoxin during a hemodialysis treatment the technician responds to a low venous pressure alarm. the most likely cause for this alarm - disconnection of the blood line the hemodialysis machine continuously monitors may parameters. which of the these parameters must be verified by an external measuring device? - ph and conductivity which of the following is most likely to cause a high venous pressure alarm? - kinking of the venous blood line during the set-up of a hemodialysis machine, the alarm test for conductivity fails. which of these actions should the dialysis technician take? - notify the equipment technician rinse in transmembrane pressure in a low flux dialyzer during hemodialysis is indicative of - clotting of the extrecorporeal circuit one reason that normal saline is used to rinse and prime the extracorporeal circuit prior to treatment is to remove - air which of the following best describes the transducer protector? - device inside the machine that converts air pressure into electronic signal which of the following would cause a high venous pressure alarm? - venous needle is against the wall of the vessels
