CNT – CCAHM QUESTIONS AND CORRECT ANSWERS (VERIFIED ANSWERS) | NEW
UPDATE 2025
Question 1
To reduce the risk of inducing a pneumothorax, needles inserted in points located on the upper
back and chest (thoracic area) should be:
A) inserted perpendicularly to the skin surface.
B) inserted up to the handle for maximum stimulation.
C) inserted obliquely or transversely along the skin surface.
D) inserted only after confirming the patient is holding their breath.
E) restricted to a depth of no more than 0.5 cun.
Correct Answer: C) inserted obliquely or transversely along the skin surface
Rationale: The upper back and chest overlie the lungs. Inserting needles obliquely (at an
angle) or transversely (along the surface) significantly limits the depth of penetration, thus
minimizing the risk of puncturing the pleura and causing a pneumothorax, which is a critical
safety measure in CNT.
Question 2
Insertion site pain may occur if which essential clean needle technique step is skipped or
performed inadequately before needle insertion?
A) Immediately isolating used sharps.
B) Setting up a clean field with a new paper towel.
C) Allowing the alcohol or disinfectant to completely air dry.
D) Washing hands for a full two minutes.
E) Using a cotton ball soaked in alcohol for skin preparation.
Correct Answer: C) Allowing the alcohol or disinfectant to completely air dry
Rationale: Alcohol acts as a local irritant. If a needle is inserted while the alcohol used for skin
preparation is still wet, the needle can drag the alcohol into the subcutaneous tissue, causing
a sharp, stinging sensation or burning pain. Allowing it to fully dry also maximizes its
antiseptic effect.
,Question 3
What is the reported approximate rate of pneumothorax occurrence per 1,000 acupuncture
visits in the United States?
A) Approximately 5 to 10.
B) Approximately 10 to 20.
C) Approximately 1 to 2.
D) Less than 0.1.
E) Approximately 1.
Correct Answer: D) Less than 0.1
Rationale: Severe adverse events, including pneumothorax, are considered very rare in
acupuncture. The rate is often cited as less than 1 per 10,000 treatments or, as per the context
provided, much lower than 1 per 1,000, suggesting a rate closer to 0.01 per 1,000 or less than
0.1 per 1,000 visits, confirming the rarity of this event.
Question 4
A patient taking anticoagulant medications (blood thinners) presents for acupuncture. What is
the appropriate clean needle technique consideration?
A) Needling is absolutely contraindicated (forbidden) due to excessive risk of bleeding.
B) Needling is permitted only on the extremities.
C) Needling should be done with extra care, brief retention, and immediate, sustained pressure
upon needle removal.
D) Needles must be removed immediately if any drop of blood appears.
E) Only intradermal needling techniques are permitted.
Correct Answer: C) Needling should be done with extra care, brief retention, and immediate,
sustained pressure upon needle removal.
Rationale: Taking anticoagulants is not an absolute contraindication for acupuncture. The
practitioner must take extra precautions to minimize bruising and bleeding by using finer
needles, avoiding vigorous manipulation, and applying sustained, direct pressure to the point
immediately after needle removal until bleeding stops and a clot forms. Complete prohibition
is generally considered unnecessary.
,Question 5
Which statement accurately reflects the prevalence of severe adverse events related to
acupuncture needling, according to safety data?
A) They occur at a rate comparable to minor adverse events like bruising.
B) They are relatively common, necessitating extensive safety training.
C) They are very rare and typically associated with poor technique or contraindications.
D) They are primarily related to bloodborne pathogen transmission.
E) They only occur in high-risk patient populations.
Correct Answer: C) They are very rare and typically associated with poor technique or
contraindications.
Rationale: Extensive research and safety data indicate that severe adverse events (such as
pneumothorax, serious infection, nerve injury) from acupuncture needling are extremely rare.
The vast majority of reported incidents are minor, such as bruising, minor bleeding, or mild
pain.
Question 6
Regarding the use of needles from multipacks in a busy clinic setting, what is the appropriate
CNT guideline?
A) Needles from multipacks can be used for up to two patients if used within 30 minutes of
opening.
B) Needles from multipacks are acceptable for multiple points on the same patient during one
visit.
C) Any needle removed from its sterile packaging must be used on the current patient or
immediately discarded.
D) Needles can be stored in a clean, closed container for up to one hour after opening.
E) Needles must be opened one at a time immediately before insertion.
Correct Answer: C) Any needle removed from its sterile packaging must be used on the
current patient or immediately discarded.
Rationale: The principle of single-use, disposable needles extends to the packaging. Once a
multi-pack is opened, any unused needles are considered compromised (no longer
, guaranteed sterile) and must be discarded, even if they were intended for the same patient.
Needles are single-use, single-patient devices.
Question 7
The Clean Needle Technique (CNT) Manual requires specific procedures for preparing the
treatment table. What is the minimum standard for table linens?
A) Table linens and paper must be changed if they are visibly soiled.
B) New table paper and clean table drapes/sheets (if used) must be replaced for every patient
visit.
C) Table paper can be wiped down with a low-level disinfectant between patients.
D) Only new paper towels are required, and cloth linens can be reused if they look clean.
E) Table linens are only required to be washed at the end of the clinic day.
Correct Answer: B) New table paper and clean table drapes/sheets (if used) must be replaced
for every patient visit.
Rationale: To prevent cross-contamination and adhere to standard precautions, the
environment of care must be clean. This critical step requires that all barrier materials (paper,
linens, drapes) that come into contact with the patient are single-patient use and replaced
between every single patient visit, regardless of apparent soiling.
Question 8
Which action is considered the single most critical step an acupuncturist takes immediately
before needle insertion to prevent patient-to-patient or environment-to-patient infection?
A) Applying a clean guide tube to the skin.
B) Washing the practitioner's hands with soap and water or an alcohol-based rub.
C) Using a new, disposable paper towel for the clean field.
D) Cleaning the skin with alcohol.
E) Counting all needles before the treatment begins.
Correct Answer: B) Washing the practitioner's hands with soap and water or an alcohol-based
rub.
Rationale: Hand hygiene is the cornerstone of infection control. Washing or sanitizing hands
immediately before needle insertion is a critical step in CNT because the practitioner's hands
