CCHT NEWEST 2024 PRACTICE EXAM COMPLETE 238 QUESTIONS
AND CORRECT DETAILED ANSWERS WITH RATIONALES (VERIFIED
ANSWERS) ALREADY GRADED A+
1. A condition caused when the surgical diversion of the arterial blood
supply through the vascular access deprives the distal portion of the
access extremity of oxygenated blood.: steal syndrome
2. A narrowing of blood vessels due to the build up of hypertrophic tissue,
anatomical narrowing if the vessels, or surgical technique problems.: is
stenosis
3. annually: AAMI Chemical Analysis of water used for hemodialysis i
tested
4. Clean the machine surface immediately: A dialysis technician observes a
drop of blood on the surface of a patient's hemodialysis machine.
5. Was the predialysis sample drawn from the venous port?: A patient's
labo- ratory results indicate that the predialysis BUN level was lower
than the post dialysis BUN level. When interpreting these findings the
technician should seek the answer to which of these questions?
6. 500: A patient's dry weight is 154.0 (70kg) and the patient's pre
treatment weight is 158.4. (72kg). For a four- hour treatment, how many
mL/ hour must the patient lose to reach dry weight?
7. 200 CFU/mL: AAMI standards for the total microbial count of dialysate
shall not exceed:
8. You don't have enough red blood cells to carry oxygen: A patient tells
the technician. "The doctor told me I'm anemic what does that mean"?
Which response by the technician would be correct?
,9. Before each patient shift: According to the standards of the
Association for the Advancement of Medical Instrumentation (AAMI), pre
treatment water should be checked for chloramines at which of these
times?
10. The patient must receive dialysis in a hospital in a special isolation
room: A patient on hemodialysis goes to the emergency department for
persistent coughing and fever. He is diagnosed with active tuberculosis
(TB) which of the following actions would the technician expect to be
taken in regard to the patient's dialysis treatment?
11. 6-8 weeks: How long does it take a Fistula to mature
, 12.1,385 mL/hr: Based on Mrs Smith's total amount of fluid to be
removed, what is the ultrafiltration rate per hour (mL/hr) for her 4 hour
treatment?
13.Discard the needle: Before a hemodialysis treatment, the technician
removes the cap from the fistula needle and accidentally touches the
chair with the tip of the needle. Which of these actions should the
technician take first?
14.Hemolysis: Dialysate that is too hot will cause
15.Weight at which the patient has no edema or fluid in the lungs and BP
is normal: Dry weight is defined as the
16.Disconnection of the bloodline: During a hemodialysis treatment the
techni- cian responds to a low venous pressure alarm. The most likely
cause for this alarm is:
17.Blood: Biohazardous waste includes any material exposed to:
18.Diffusion: Decreasing the patient's prescribed blood flow rate affects
the rate of
19.Stop the pump: During a hemodialysis treatment, a patient's
venous needle infiltrates. Which of these actions should the dialysis
technician take first?
20.Between 7.0 and 7.4: Dialysate pH should be:
21.Clamp the venous line: During hemodialysis, the air detector on Ms.
Foster's machine alarms and foam is visible in the venous drop
chamber. The immediate action of the dialysis technician should be to:
22.How have you been since your last dialysis treatment?: During
predialysis data collection, it would be best for the technician to ask the
patient which of these questions?
23.Take the patient's temperature: During the hemodialysis treatment, a
patient complains of feeling chilled. In addition to getting the patient a
blanket, which of these actions should the technician take?
