CCHT REVIEW 2027 ANSWERS AND QUESTIONS SET
A+
✔✔if using a combination chlorhexidine gluconate and alcohol skin prep (such as
chloraprep before cannulation, how much skin contact time is required? - ✔✔30
seconds
✔✔which of the following preventive measures is usually the best approach for patients
who routinely experience hypotension during dialysis because of volume-related
problems associated with large weight gain between treatments? - ✔✔increasing
restrictions of sodium intake
✔✔if a patient undergoing hemodialysis and in the care of the technician has a
persistent cough, standards precautions require that the - ✔✔patient wear a mask
✔✔what color is arterial blood tubing for hemodialysis most often color-coded? - ✔✔red
✔✔during hemodialysis, how much blood is usually outside of a patient's body at one
time? - ✔✔100 to 250mL
✔✔during 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 of - ✔✔25-35
✔✔a hemodialysis system includes blood volume monitoring to assess changes in the
patients democrat.if the hematocrit increases rapidly, this means - ✔✔blood volume is
decreased
✔✔a 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 should -
✔✔collapse
, ✔✔during cannulation, a tourniquet should be used - ✔✔while placing needles in all AV
fistula
✔✔the difference between a buttonhole needle and a standard needle for hemodialysis
is that the buttonhole needle has a - ✔✔blunt tip
✔✔if a hemodialysis patient has an extreme fear of needle and the physician describe
EMLA cream to prevent pain, the cream must be applied - ✔✔60 minutes prior to
treatment
✔✔following formation of an AV fistula and beginning of hemodialysis, the technician
notes that the patient's nailed and skin on the hand below the fistula are cyanotic during
hemodialysis, and the patient complains of pain in the hand. this is likely an indication of
- ✔✔steal syndrome
✔✔after a hemodialysis needle is removed at the end of treatment, the correct
procedure is to apply pressure to - ✔✔each access site with two fingers for up to 20
minutes
✔✔a patient who wants to learn self-cannulation may do so if - ✔✔the patient receives
appropriate training
✔✔thrombosis is newly-created access may be caused by - ✔✔low blood pressure
✔✔if a new patient has Hero (hemodialysis reliable outflow) graft, the cannulation site is
generally in the - ✔✔proximal upper arm (below the axilla).
✔✔if effluent (used dialysate ) spills into the floor, the technician should - ✔✔notify staff
trained in hazardous waste removal
✔✔a patient is recovering hemodialysis with 17-gauge needle, but his blood flow rate
has been increased to 450ml/min. the patient complains of symptoms consisten with
hemodialysis ( breakdown of red blood cells) sudden onset of chest tightness, back
pain, dyspnea, reddening ok skin color, and blood in the venous line appearing port-
wine in color. what is likely cause of this complication? - ✔✔needle too small for blood
flow rate
✔✔when handing off a patient to another staff person, the technician should always -
✔✔follow the hand-off protocol established by the institution
✔✔the technician should ensure when exposing the opening of a central catheter to air
(such as when removing the cap or a syringe) that the - ✔✔clamp is closed
