ACTUAL EXAM 2026/2027 COMPLETE
ACCURATE EXAM REAL QUESTIONS WITH
WELL ELABORATED ANSWERS AND
RATIONALES. (100% CORRECT VERIFIED
SOLUTIONS)
1. How often must the dialysis station (machine, chair, table) be
cleaned and disinfected between patients?
A) At the end of each shift only
B) Between every patient
C) Once daily
D) Only if visible blood is present
,Page 2 of 168
Answer: B
Rationale: CDC and NYSDOH require disinfection of all
patient-care surfaces between every patient to prevent cross-
contamination.
2. Which disinfectant concentration is required for cleaning a
dialysis machine after a hepatitis B surface antigen (HBsAg)-
positive patient?
A) 1:100 bleach (500–600 ppm)
B) 1:1000 bleach
C) 70% isopropyl alcohol
D) Quaternary ammonium compound
Answer: A
Rationale: 1:100 bleach (500–600 ppm) is virucidal against
HBV. Lower concentrations may not be effective.
3. A technician removes gloves, washes hands with soap and
water, then applies alcohol hand rub before touching the next
patient. Is this correct?
,Page 3 of 168
A) Yes, double hand hygiene is best
B) No, alcohol rub after soap and water is unnecessary and
may dry skin
C) No, soap and water is sufficient
D) Yes, but only if the patient is immunocompromised
Answer: B
Rationale: Either soap and water or alcohol rub is sufficient
unless hands are visibly soiled. Doing both is unnecessary.
4. (Scenario) You accidentally splash blood into your eye while
disconnecting a patient. What is the first action?
A) Complete the disconnect, then report to supervisor
B) Immediately flush eye with water for 15 minutes and report
C) Apply antibiotic eye drops
D) Wipe eye with alcohol pad
Answer: B
Rationale: Immediate, prolonged irrigation (15 min) reduces
, Page 4 of 168
risk of bloodborne pathogen transmission. Then report for
post-exposure evaluation.
5. The acceptable maximum bacterial count in dialysate
according to AAMI standards is:
A) 50 CFU/mL
B) 100 CFU/mL
C) 200 CFU/mL
D) 500 CFU/mL
Answer: B
Rationale: AAMI RD52:2004 requires dialysate bacterial count
<100 CFU/mL and endotoxin <0.5 EU/mL.
6. Endotoxin in dialysate can cause:
A) Hypotension, fever, chills during dialysis
B) Hyperkalemia
C) Air embolism
D) Hemolysis
