CCHT EXAM 2026/2027 QUESTIONS AND VERIFIED
ANSWERS | Certified Clinical Hemodialysis Technician
Practice Exam | 100% Guarantee Pass Score | A+ Graded
Q1: A patient arrives for hemodialysis with a blood pressure of 185/110 mmHg and
reports a severe headache. Which action should the technician take FIRST?
A. Proceed with dialysis at a reduced blood flow rate
B. Administer acetaminophen per standing order and continue monitoring
C. Notify the nurse immediately and hold dialysis initiation pending evaluation
[CORRECT]
D. Increase the ultrafiltration rate to reduce fluid overload quickly
Correct Answer: C
Rationale: Severe hypertension (Stage 2: >180/120 mmHg) with neurological symptoms
(headache) may indicate hypertensive emergency or impending intracranial
hemorrhage. The CCHT must immediately escalate to the RN for assessment before
initiating dialysis, which could further stress the cardiovascular system. Distractor A is
dangerous—dialysis could exacerbate hypertension or cause seizures. Distractor B
delays necessary medical evaluation and exceeds CCHT scope (medication
administration requires RN/physician order verification). Distractor D is
contraindicated—aggressive ultrafiltration can cause hypotension, cramping, and further
neurological compromise. Per CMS Conditions for Coverage and AAMI standards,
CCHTs must recognize critical values and follow chain of command.
Q2: Which water treatment component is PRIMARILY responsible for removing
chloramines from the dialysate water supply?
,A. Reverse osmosis (RO) membrane
B. Softener resin bed
C. Carbon adsorption tanks [CORRECT]
D. Ultraviolet (UV) light system
Correct Answer: C
Rationale: Carbon tanks (activated carbon) adsorb chlorine and chloramines through
chemical binding to the carbon surface. This is critical because chloramines cause
hemolytic anemia and methemoglobinemia. Per AAMI RD62:2026 and CMS regulations,
carbon tanks must be installed in series with daily testing for total chlorine (chloramine)
breakthrough at <0.1 ppm. Distractor A (RO) removes dissolved ions, bacteria, and
endotoxins but is poor at removing chloramines (small, uncharged molecules).
Distractor B (softener) exchanges calcium/magnesium for sodium to prevent scaling.
Distractor D (UV) disinfects by damaging microbial DNA but does not remove chemical
contaminants.
Q3: A patient's pre-dialysis weight is 72.5 kg, and their prescribed dry weight is 69.0 kg.
The treatment time is 4 hours. What is the required ultrafiltration rate (UFR) in mL/hr?
A. 583 mL/hr
B. 725 mL/hr
C. 875 mL/hr [CORRECT]
D. 1,250 mL/hr
Correct Answer: C
Rationale: Calculation: (72.5 kg - 69.0 kg) = 3.5 kg fluid gain = 3,500 mL. 3,500 mL ÷ 4
hours = 875 mL/hr. The CCHT must verify this UFR is safe (generally <13 mL/kg/hr to
prevent intradialytic hypotension; here 875 ÷ 72.5 = 12.1 mL/kg/hr, acceptable).
Distractor A calculates 3,500 ÷ 6 hours incorrectly. Distractor B uses 72.5 kg as the
, divisor incorrectly (3,500 ÷ 4.83). Distractor D results from treating 3.5 kg as 3,500 mL
but dividing by 2.8 hours or miscalculating decimal placement.
Q4: Which laboratory value trend indicates INADEQUATE dialysis delivery?
A. Pre-dialysis BUN 65 mg/dL, post-dialysis BUN 20 mg/dL
B. Kt/V 1.0, URR 60% [CORRECT]
C. Pre-dialysis creatinine 8.2 mg/dL, post-dialysis 3.1 mg/dL
D. Serum phosphorus decreasing from 6.5 to 4.8 mg/dL with binder therapy
Correct Answer: B
Rationale: Current KDOQI 2026 guidelines recommend minimum Kt/V ≥1.2 (single pool)
or URR ≥65% for adequate dialysis. Kt/V 1.0 and URR 60% fall below minimum
standards, indicating insufficient clearance. Distractor A shows appropriate BUN
reduction (69% reduction). Distractor C shows adequate creatinine clearance (62%
reduction). Distractor D demonstrates effective phosphorus management. The CCHT
must recognize that Kt/V combines clearance (K), time (t), and volume of urea
distribution (V) to assess dialysis adequacy.
Q5: During cannulation of an arteriovenous fistula (AVF), the technician feels a "thrill"
but hears a high-pitched whistle over the venous limb. What does this finding suggest?
A. Normal fistula function with adequate blood flow
B. Venous outflow stenosis [CORRECT]
C. Arterial inflow stenosis
D. Aneurysm formation with turbulent flow
Correct Answer: B
Rationale: A high-pitched, continuous whistle (bruit) over the venous limb indicates
turbulent flow from venous outflow obstruction/stenosis, often proximal to the
