is evident in the used dialysate, this probably indicatestear in the membraneif a patient asks a question to which the technician does not know the answer, an appropriate response isI 'll find out for you ''during routine hemodialysis, a patient's blood pressure should monitored every30 to 60 minutesif a patient develops painful muscle cramps in the hands, feet, and abdomen shortly after hemodialysis begins, the most likely interventions issaline bolus and/or decreased ultrafiltration rate.if a hemodialysis patient's temperature per tympanic membrane thermometer is 37C in order to reduce incidendence of intradialytic ( during dialysis ) hypotension, the temperature of the dialysate solution should ideally be set at36.5 Cfoam in the venous bloodline of a dialyzer may indicateair embolismprior to initiating hemodialysis, the ph of the dialyste usually ranges from7.0 to 7.4the number one cause of kidney failure in the US isdiabetes mellitus, type 2the use of topical anesthetic, such as EMLA, to reduce discomfort during cannulation is contraindicated withbuttonhole sitesa patient who has been very alert and shown no sign of cognitive impairment seems confused during dialysis and repeatedly asks the same question. the best initial response is tonotify the nursewhen determining if a new AV fistula is maturing the three factors to assess by palpation are thethrill, vessel growth, and vessel firmnesswhich of the following antiseptics used for skin pre for a fistula site has the broadest spectrum antibacterial activity?2% chlorhexidine gluconatewhile a patient is undergoing hemodialysis, chloramine testing of the water system should be conducted every4 hoursif a patient is to undergo heparin-free dialysis, the optimal blood flow rate is300 to 400 ml/minbefore cannulating An AV fistula for a hemodialysis treatment, the technician examines the patient's access arm and finds that the access arm appears slightly edamatous, and the skin is pale. on further examination, the technician notes that there are small purple veins evident on the chest wall near where the arm meets the body. the technician should suspectstenosisin order to increase survival rates. the ultrafiltration rate for hemodialysis patients should be maintained at least than12 ml/kg/mas part of fistula assessment before cannulation, the technician evaluates the thrill and then applies acclusion by placing a finger across the body of the fistula. while the fistula is acceded, the technician palpates and feels both a thrill and a pulse. this probably signifies a (n)accessory pathway ( collateral circulation )how much additional proteins should a patient on hemodialysis ingest every day in comparison to a health person50%weight gain between hemodialysis treatments should not exceed5% of dry weightthe technician has calculate the target weight loss for a patent's hemodialysis session, but the patient insists that the technician has made an error and the target is 1 kg too high. the technician shouldrecalculate the target weight loss.the most important reason for placing hemodialysis needles in antegrade position ( in direction of blood flow) is becauseit causes

monitoring stops dialysate from flowing to the dialyzer but instead sends it to the drain (bypass), this means thatthe conductivity monitor is malfunctioningwhen using a portable digital dialysate meter, such as the D6 (myron L meter ) , to verify that inline meters are accurate regarding conductivity and ph, the technician mustobtain an unused dialysate samplethe target ultrafiltration goal set for the patient is based on the patient'sdry weighta patient is to receive a bolus of ulfrationated heparin (25 IU/kg ) at the onset of dialysis and 800 U at one-hour intervals during treatment, which is scheduled from 1 to 5 PM. the first dose is given at 1 Pm and the last dose at4 pmwhen checking the pump occlusion for the blood pump, the technician nots, that the rollers appear to loose.this may result incracking of the blood pump segment of tubingin the hemodialysis machine, a separate air detector is usually placedbetween the venous pressure gauge and the venous accessat the completion of dialysis treatment, it is important to rinse back as much blood as possible in order toreduce the severity anemiaif a power outage occurs and backup power fails, before using the hand crank to return the patient's blood, the technician mustremove the venous line for the air detectorif a patient's blood pressure is 142/88 before dialysis and 108/72 at the completion of dialysis, the most likely intervention isinfusion of normal saline to increase blood pressureprior to opening a sterile packing, the technician spills sterile normal saline on the package. the technician

hemodialysis, how much blood is usually outside of a patient's body at one time?100 to 250mLduring the first week of treatment with a new AV fistula, the initial needle size and blood flow rate are usually ~17-gauge needle and blood flow of 200 to 250 mL/min.with an AV fistula, cannulation should usually be done at an angle of25-35a hemodialysis system includes blood volume monitoring to assess changes in the patients democrat.if the hematocrit increases rapidly, this meansblood volume is decreaseda patient has a newly created AV fistula. when assessing the fistula, the technician raises the patients involved arm above the head. in this position, the fistula shouldcollapseduring cannulation, a tourniquet should be usedwhile placing needles in all AV fistulathe difference between a

hand below the fistula are cyanotic during hemodialysis, and the patient complains of pain in the hand. this is likely an indication ofsteal syndromeafter a hemodialysis needle is removed at the end of treatment, the correct procedure is to apply pressure toeach access site with two fingers for up to 20 minutesa patient who wants to learn self-cannulation may do so ifthe patient receives appropriate trainingthrombosis is newly-created access may be caused bylow blood pressureif a new patient has Hero (hemodialysis reliable outflow) graft, the cannulation site is generally in
