CNT (Clean Needle Technique) Written
Exam — Complete Practice Question
Bank (2026/2027).
Q1: The primary purpose of Clean Needle Technique (CNT) is to:
A. Increase treatment efficacy through deeper needling
B. Reduce the risk of spreading infection from patient to patient, patient to practitioner, or
practitioner to patient [CORRECT]
C. Guarantee that no adverse events ever occur
D. Eliminate the need for hand hygiene after every patient
Correct Answer: B
Rationale: CNT is specifically designed to minimize infection transmission risks in acupuncture
practice. Options A and C address clinical outcomes rather than infection control, while D
contradicts a core CNT principle.
Q2: Which of the following correctly defines sterilization?
A. Reduction of microbes on living tissue
B. Reduction of the number of microbes on inanimate objects
C. Destruction of all microbial life, including viruses [CORRECT]
D. Use of alcohol on the skin prior to needling
Correct Answer: C
Rationale: Sterilization destroys all microbial life. Disinfection reduces microbes on surfaces,
and antiseptics reduce microbes on living tissue. These distinctions are foundational in the
CNT Manual.
Q3: Disinfection is best described as:
A. Destruction of all microbial life including spores
B. Reduction of the number of microbes on inanimate objects [CORRECT]
C. Application of chemicals to living tissue
,D. A process that makes needles reusable indefinitely
Correct Answer: B
Rationale: Disinfection reduces microbial load on non-living surfaces but does not achieve
sterility. Sterilization is more complete; antiseptics are used on tissue.
Q4: An antiseptic is a chemical agent used to:
A. Sterilize reusable cups and tools
B. Reduce the number of microbes on living tissue [CORRECT]
C. Destroy all viruses on environmental surfaces
D. Clean the floor of the treatment room
Correct Answer: B
Rationale: Antiseptics are formulated for living tissue (e.g., skin preparation). Disinfectants
and sterilants are used on inanimate objects.
Q5: The five essential steps of Clean Needle Technique include all of the following EXCEPT:
A. Wash hands before needling
B. Use single-use sterile needles
C. Reuse guide tubes for multiple patients if wiped with alcohol
D. Immediately isolate used sharps
Correct Answer: C
Rationale: Clean fields, needles, and guide tubes are for one patient only. Reusing guide tubes
violates CNT protocol. The five steps are: wash hands, single-use needles, clean field per
patient, immediate sharps isolation, and standard precautions.
Q6: Which of the following is one of the five essential steps of CNT?
A. Always wear gloves for every needle insertion
B. Set up a clean field for each patient [CORRECT]
C. Recap needles carefully after use
D. Soak used needles in alcohol before disposal
Correct Answer: B
, Rationale: Establishing a clean field for each individual patient is a required CNT step. Gloves
are not mandatory for every insertion, and recapping or soaking needles is prohibited.
Q7: According to CNT protocol, which sequence correctly reflects the five essential steps?
A. Wash hands → single-use needles → clean field per patient → isolate sharps immediately
→ follow standard precautions [CORRECT]
B. Glove up → sterilize needles → clean field for the day → recap needles → document
exposure
C. Sanitize hands → multi-use needles → shared clean field → dispose at end of day → follow
OSHA only
D. Wash hands only if soiled → single-use needles → clean field for multiple patients →
isolate sharps → no PPE needed
Correct Answer: A
Rationale: This is the exact sequence taught in the CNT Course. Any deviation (shared fields,
recapping, delayed disposal) increases infection risk.
Q8: “Standard of care” in the context of CNT refers to:
A. The highest possible level of technique a master practitioner would use
B. What a minimally competent clinician with the same training would do under similar
circumstances [CORRECT]
C. Following only the most expensive infection-control products
D. The personal preference of the clinic owner
Correct Answer: B
Rationale: Standard of care is the legal and professional baseline of competent practice. CNT
protocols define this baseline for infection control.
Q9: A clean field is defined as:
A. The entire treatment room after daily mopping
B. A section of the work surface prepared to protect needle sterility for one patient
[CORRECT]
C. Any surface wiped with alcohol at the start of the day
D. The practitioner’s hands after washing
