✔✔during routine hemodialysis, a patient's blood pressure should monitored every -
✔✔30 to 60 minutes
,✔✔if a patient develops painful muscle cramps in the hands, feet, and abdomen shortly
after hemodialysis begins, the most likely interventions is - ✔✔saline 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 at - ✔✔36.5 C
✔✔foam in the venous bloodline of a dialyzer may indicate - ✔✔air embolism
✔✔prior to initiating hemodialysis, the ph of the dialyste usually ranges from - ✔✔7.0 to
7.4
✔✔the number one cause of kidney failure in the US is - ✔✔diabetes mellitus, type 2
✔✔the use of topical anesthetic, such as EMLA, to reduce discomfort during
cannulation is contraindicated with - ✔✔buttonhole sites
✔✔a 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 to - ✔✔notify the nurse
✔✔when determining if a new AV fistula is maturing the three factors to assess by
palpation are the - ✔✔thrill, vessel growth, and vessel firmness
✔✔which of the following antiseptics used for skin pre for a fistula site has the broadest
spectrum antibacterial activity? - ✔✔2% chlorhexidine gluconate
✔✔while a patient is undergoing hemodialysis, chloramine testing of the water system
should be conducted every - ✔✔4 hours
✔✔if a patient is to undergo heparin-free dialysis, the optimal blood flow rate is - ✔✔300
to 400 ml/min
✔✔before 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 suspect - ✔✔stenosis
✔✔in order to increase survival rates. the ultrafiltration rate for hemodialysis patients
should be maintained at least than - ✔✔12 ml/kg/m
, ✔✔as 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 person - ✔✔50%
✔✔weight gain between hemodialysis treatments should not exceed - ✔✔5% of dry
weight
✔✔the 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 should - ✔✔recalculate the target weight loss.
✔✔the most important reason for placing hemodialysis needles in antegrade position (
in direction of blood flow) is because - ✔✔it causes less scarring

1.0 part acid and 1.72 parts bicarbonate, how many parts of water are needed? -
✔✔42.28
✔✔if conductivity monitoring stops dialysate from flowing to the dialyzer but instead
sends it to the drain (bypass), this means that - ✔✔the conductivity monitor is
malfunctioning
✔✔when 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 must
- ✔✔obtain an unused dialysate sample
✔✔the target ultrafiltration goal set for the patient is based on the patient's - ✔✔dry
weight
✔✔a 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 at - ✔✔4 pm
✔✔when checking the pump occlusion for the blood pump, the technician nots, that the
rollers appear to loose.this may result in - ✔✔cracking of the blood pump segment of
tubing
