Section 1: CNT Written Exam Practice Questions
Q1: What is the primary purpose of clean needle technique in acupuncture practice?
A. To enhance treatment efficacy
B. To prevent transmission of bloodborne pathogens and infection
C. To reduce patient anxiety during treatment
D. To standardize needle insertion depth
Correct Answer: B
Rationale: Clean needle technique is fundamentally designed to prevent the transmission of
bloodborne pathogens such as HIV, HBV, and HCV, as well as bacterial infections, by ensuring
sterile procedures and proper handling of needles and equipment. [CORRECT]
Q2: According to OSHA Bloodborne Pathogens Standard, how long must training records be
maintained?
A. 1 year
B. 3 years
C. 5 years
D. 10 years
Correct Answer: B
Rationale: OSHA requires that training records for bloodborne pathogens be maintained for 3
years from the date of training, ensuring compliance documentation and accessibility for
inspections. [CORRECT]
Q3: Which of the following is considered a critical control point in clean needle technique?
A. Room temperature maintenance
B. Hand hygiene before patient contact
C. Selection of needle gauge
1
,2
D. Patient positioning
Correct Answer: B
Rationale: Hand hygiene is a critical control point because hands are the primary vehicle for
transmitting microorganisms; proper handwashing or sanitization before patient contact
significantly reduces infection risk. [CORRECT]
Q4: What is the recommended needle disposal container characteristic?
A. Clear plastic for visibility
B. Puncture-resistant, leak-proof, and labeled with biohazard symbol
C. Open-top for easy access
D. Reusable after proper cleaning
Correct Answer: B
Rationale: Sharps containers must be puncture-resistant to prevent needlestick injuries, leak-
proof to contain fluids, and labeled with the biohazard symbol to warn of infectious content per
OSHA and CDC guidelines. [CORRECT]
Q5: In the event of a needlestick injury, what is the first immediate action?
A. Apply antibiotic ointment
B. Wash the affected area with soap and water
C. Report to OSHA immediately
D. Continue with patient treatment
Correct Answer: B
Rationale: Immediate washing of the needlestick site with soap and water helps flush out
potentially infectious material and is the critical first step before seeking further medical
evaluation and reporting. [CORRECT]
Q6: Which bloodborne pathogen has the highest concentration in blood and is most infectious?
A. Hepatitis C Virus (HCV)
B. Human Immunodeficiency Virus (HIV)
C. Hepatitis B Virus (HBV)
D. Hepatitis A Virus (HAV)
Correct Answer: C
2
,3
Rationale: HBV is the most infectious bloodborne pathogen with concentrations up to 100 times
higher than HIV in blood, making it the greatest occupational risk for healthcare workers
including acupuncturists. [CORRECT]
Q7: What is the minimum personal protective equipment (PPE) required when performing
acupuncture?
A. Gloves only
B. Gloves and mask
C. Gloves and eye protection
D. No PPE required for standard acupuncture
Correct Answer: A
Rationale: Standard acupuncture requires gloves as minimum PPE to protect both practitioner
and patient from blood exposure; additional PPE is required only when risk of splash or spray
exists. [CORRECT]
Q8: How should reusable acupuncture guide tubes be processed between patients?
A. Wiped with alcohol
B. High-level disinfection or sterilization
C. Rinsed with water
D. Single-use only, never reused
Correct Answer: B
Rationale: Reusable guide tubes must undergo high-level disinfection or sterilization between
patients to eliminate all microorganisms including bloodborne pathogens, as they contact both
needles and patient skin. [CORRECT]
Q9: Which anatomical location requires extreme caution due to risk of pneumothorax during
needle insertion?
A. LI4 (Hegu)
B. ST36 (Zusanli)
C. BL13 (Feishu)
D. SP6 (Sanyinjiao)
Correct Answer: C
3
, 4
Rationale: BL13 (Feishu) is located near the scapula overlying lung tissue; improper needle
insertion angle or depth can cause pneumothorax, making it a high-risk point requiring precise
technique. [CORRECT]
Q10: What is the standard angle of needle insertion for points on the scalp?
A. 15-30 degrees
B. 45 degrees
C. 90 degrees (perpendicular)
D. 5-10 degrees (transverse)
Correct Answer: D
Rationale: Scalp points require transverse (subcutaneous) insertion at 5-10 degrees to avoid
penetrating the skull while effectively stimulating the point and preventing serious injury.
[CORRECT]
Q11: According to CDC guidelines, how long should hands be washed with soap and water?
A. 10 seconds
B. 15-20 seconds
C. 30 seconds
D. 1 minute
Correct Answer: B
Rationale: The CDC recommends washing hands with soap and water for at least 15-20 seconds
to effectively remove transient microorganisms and reduce bioburden before patient contact or
aseptic procedures. [CORRECT]
Q12: Which of the following is an absolute contraindication for acupuncture?
A. Patient anxiety
B. Local skin infection at the intended insertion site
C. Mild headache
D. Previous acupuncture experience
Correct Answer: B
Rationale: Local skin infection is an absolute contraindication because inserting needles through
infected tissue can spread bacteria to deeper tissues or bloodstream, worsening infection and
causing complications. [CORRECT]
