Introduction
This comprehensive examination is designed to rigorously assess the candidate’s readiness for the NBCE Part 2
Chiropractic Board Exam. It evaluates a deep understanding of foundational biomedical sciences, clinical application,
and the critical thinking necessary for effective patient management. The assessment employs a multiple-choice and
scenario-based format to measure the integration of knowledge from basic sciences to clinical decision-making, with a
strong emphasis on differential diagnosis, treatment planning, and professional ethics. The exam underscores the
importance of evidence-based practice and the application of chiropractic principles in real-world clinical settings,
ensuring candidates are equipped to deliver safe, competent, and ethical patient care.
,SECTION ONE: QUESTIONS 1–100
1. A patient presents with acute low back pain following a lifting injury. During the initial consultation, which of
the following findings is the MOST significant "red flag" indicating a potential serious underlying pathology?
A. Pain that is worse with flexion
B. Pain that is worse with extension
C. History of unexplained weight loss
D. Positive Straight Leg Raise test
🟢 C. History of unexplained weight loss
🔴 Explanation: Unexplained weight loss is a systemic symptom and a classic "red flag" suggesting a possible
underlying malignancy, infection, or inflammatory disease. While the other options (A, B, D) are associated with
mechanical back pain and are important for diagnosis, they are not systemic red flags. A history of unexplained
weight loss warrants immediate further investigation, including imaging and laboratory tests.
2. Which of the following anatomical structures is MOST directly responsible for the "uncovertebral joints" of the
cervical spine?
A. Articular processes
B. Vertebral bodies and intervertebral discs
C. Uncinate processes of the cervical vertebrae
D. Transverse processes
🟢 C. Uncinate processes of the cervical vertebrae
,🔴 Explanation: Uncovertebral joints, also known as joints of Luschka, are formed by the uncinate processes, which
are bony projections on the superior lateral margins of the cervical vertebral bodies (C3-C7). These processes
articulate with the beveled inferior surfaces of the vertebra above. They are not formed by the articular processes
(A), which form the zygapophyseal joints. While related to the vertebral bodies (B), the specific structure is the
uncinate process.
3. A patient presents with a chief complaint of right-sided neck pain radiating into the right arm. The pain is
exacerbated by neck extension and right lateral flexion. During the physical examination, you note a diminished
right biceps reflex. Which nerve root is MOST likely involved?
A. C5
B. C6
C. C7
D. C8
🟢 B. C6
🔴 Explanation: The biceps reflex is primarily mediated by the C5 and C6 nerve roots, with C6 being the most
dominant. Radicular pain and diminished reflexes in this distribution, especially with exacerbation by extension and
lateral flexion (which narrows the intervertebral foramen), strongly suggests a C6 nerve root involvement. While C5
(A) also contributes to the biceps reflex, the classic pattern of this presentation points most directly to C6. C7 (C) is
tested with the triceps reflex, and C8 (D) is tested with the finger flexor reflex.
4. A 45-year-old female presents with a 3-month history of bilateral hand pain, numbness, and tingling that is
worse at night. She reports that shaking her hands relieves the symptoms. Which of the following is the MOST
appropriate initial diagnostic test to confirm your suspected diagnosis?
, A. Cervical spine MRI
B. Nerve Conduction Study (NCS) and Electromyography (EMG)
C. Phalen's maneuver and Tinel's sign
D. Complete blood count (CBC) and erythrocyte sedimentation rate (ESR)
🟢 B. Nerve Conduction Study (NCS) and Electromyography (EMG)
🔴 Explanation: The patient's symptoms are classic for Carpal Tunnel Syndrome (CTS). While provocative tests like
Phalen's maneuver and Tinel's sign (C) are useful clinical screening tools and can support the diagnosis, the gold
standard for confirming CTS is electrodiagnostic testing (NCS/EMG). This testing can objectively measure the
slowing of nerve conduction across the carpal tunnel and provide a definitive diagnosis, aiding in treatment
planning. MRI (A) is used to rule out cervical spine pathology or other structural causes, and blood work (D) helps
rule out systemic causes like hypothyroidism or inflammatory conditions but is not the primary confirmatory test for
CTS itself.
5. According to the principles of biomechanics, the "center of gravity" in a standing human adult is typically
located at which of the following landmarks?
A. The level of the umbilicus
B. The level of the iliac crests
C. The level of the xiphoid process
D. The second sacral segment
🟢 D. The second sacral segment
🔴 Explanation: In the standard anatomical position, the center of gravity (COG) of the human body is located
approximately anterior to the second sacral segment (S2). This landmark is used as a reference point for analyzing
