NBCE Part III Exam Flashcards

Q: How many questions are on the NBCE Part III exam?

The version with DXI has 130 items: 80 traditional multiple-choice questions (TMCQ), 20 extended multiple-choice case items (EMCQ), and 30 diagnostic imaging interpretation (DXI) sets. A version without DXI exists with 100 items (80 TMCQ + 20 EMCQ) for candidates who follow that track.

Q: What is the passing score for NBCE Part III?

NBCE Part III uses a scaled scoring system with a passing score of 375. Scoring is calculated across all nine clinical domains collectively rather than requiring a minimum score on each individual domain.

Q: What does NBCE Part III cost, and is sponsorship required?

The Part III exam fee is $710 as of the current NBCE fee schedule, with the same fee due for each retake. No employer or firm sponsorship is required; eligibility instead depends on chiropractic program enrollment status, having passed Part I, and typically being within nine months of graduation.

Q: What happens if I fail NBCE Part III, and is there a mandatory waiting period before retaking?

NBCE does not impose a fixed waiting period or attempt limit. You can apply to retest as soon as your score is released, but practical scheduling around testing windows typically means the next available retest is roughly two to three months out. Some chiropractic colleges layer their own remedial coursework requirements on top of this before allowing a retest.

Q: What are the nine clinical domains tested on NBCE Part III?

Case Management (15%), Diagnosis or Clinical Impression (14%), Chiropractic Techniques (14%), Case History (11%), Neuromusculoskeletal Examination (11%), Diagnostic Imaging (11%), Physical Examination (9%), Supportive Interventions (8%), and Clinical Laboratory and Special Studies (7%). DXI imaging interpretation is scored as a separate 20% overlay on top of these domains.

Question 1

What six elements does the OPQRST framework prompt a clinician to capture during a pain history?

Accepted Answer

Onset, Provocation/palliation, Quality, Radiation, Severity, and Timing - together these fully characterize a chief complaint and guide the differential diagnosis.

Question 2

A patient with new low back pain also reports losing 15 pounds without trying over the past two months. What does this combination of history findings require?

Accepted Answer

Unexplained weight loss paired with new musculoskeletal pain is a red flag for malignancy; it requires further history, exam, and imaging before assuming a purely mechanical cause.

Question 3

During history taking, a patient volunteers new saddle numbness and difficulty urinating along with severe low back pain. What must the clinician rule out immediately?

Accepted Answer

Cauda equina syndrome - saddle anesthesia plus bowel or bladder dysfunction is a surgical emergency requiring immediate emergency referral, not conservative care.

Question 4

In an acute trauma case, which history detail should be documented first, ahead of past medical or social history?

Accepted Answer

The mechanism of injury - how the injury occurred (forces involved, body position, load) shapes the differential diagnosis and directs the physical exam that follows.

Question 5

A young adult reports morning low back stiffness lasting over an hour that improves with activity, plus a family history of psoriasis. What does this history pattern suggest?

Accepted Answer

A family history of a spondyloarthropathy-associated condition combined with an inflammatory stiffness pattern raises suspicion for ankylosing spondylitis or a related spondyloarthropathy, not mechanical back pain.

Question 6

What are 'constitutional symptoms' in a case history, and why do they change the clinical picture?

Accepted Answer

Fever, chills, malaise, and night sweats - their presence alongside a musculoskeletal complaint flags possible infection or systemic illness rather than a purely biomechanical problem.

Question 7

Which four vital signs form the baseline of every physical examination?

Accepted Answer

Blood pressure, pulse rate, respiratory rate, and temperature - abnormal vitals can shift a case from musculoskeletal management toward urgent medical referral.

Question 8

A patient has right upper quadrant pain that sharply worsens, stopping their inhalation, when the examiner palpates under the right costal margin. What sign is this and what does it suggest?

Accepted Answer

A positive Murphy's sign - it suggests gallbladder inflammation (cholecystitis), pointing away from a musculoskeletal source of the pain.

Question 9

Percussion tenderness over the costovertebral angle points to irritation of which organ system?

Accepted Answer

The kidney - CVA tenderness suggests renal pathology such as pyelonephritis or nephrolithiasis, prompting medical referral rather than spinal adjustment.

Question 10

Name the four core physical exam techniques used to gather objective findings.

Accepted Answer

Inspection, palpation, percussion, and auscultation - each contributes different objective data such as posture and symmetry, tenderness and tone, organ borders, and heart, lung, or bowel sounds.

Question 11

A supine patient's leg is passively raised with the knee extended, reproducing radiating leg pain between roughly 30 and 70 degrees of hip flexion. Which test is this and what does a positive result suggest?

Accepted Answer

The straight leg raise (Lasegue) test - a positive result in that range suggests lumbar nerve root tension or irritation, commonly from disc herniation.

Question 12

A seated patient's neck is extended, rotated toward the symptomatic side, and gently compressed axially, reproducing radiating arm pain. What is this test called and what does it detect?

Accepted Answer

Spurling's test - it narrows the cervical intervertebral foramen, and a positive result reproducing radicular arm symptoms suggests cervical nerve root encroachment.

Question 13

Which orthopedic test loads the lumbar facet joints and intervertebral foramina through extension, rotation, and lateral flexion to reproduce localized or radiating pain?

Accepted Answer

Kemp's test - a positive result suggests facet joint irritation or foraminal encroachment at the tested spinal level.

Question 14

Match each deep tendon reflex to its primary nerve root level: biceps, triceps, patellar, and Achilles.

Accepted Answer

Biceps = C5, triceps = C7, patellar (knee-jerk) = L4, Achilles (ankle-jerk) = S1 - a diminished or absent reflex helps localize a specific nerve root lesion.

Question 15

A patient has numbness over the dorsum of the foot and big toe along with weak great toe extension. Which nerve root level is most likely involved?

Accepted Answer

L5 - the L5 dermatome covers the dorsal foot and big toe, and the L5 myotome drives great toe extension (extensor hallucis longus), classic for an L4-L5 disc lesion.

Question 16

A patient cannot bear weight for four steps right after twisting their ankle and has tenderness over the posterior edge of the lateral malleolus. Does the Ottawa Ankle Rule recommend an X-ray?

Accepted Answer

Yes - bone tenderness at the posterior edge or tip of either malleolus plus inability to bear weight (immediately or in the clinic) meets the Ottawa Ankle Rule threshold for an ankle X-ray.

Question 17

A 60-year-old has acute knee pain after a fall, with isolated tenderness over the fibular head. Does the Ottawa Knee Rule recommend imaging?

Accepted Answer

Yes - age 55 or older is itself one of the Ottawa Knee Rule criteria, along with isolated patellar or fibular head tenderness, inability to flex to 90 degrees, or inability to bear weight; any single criterion warrants an X-ray.

Question 18

A patient has chronic low back pain with suspected disc herniation and radicular leg symptoms. Which imaging modality best visualizes the soft tissue and nerve root involved?

Accepted Answer

MRI - it shows disc material, nerve roots, and the spinal cord in detail without ionizing radiation, unlike X-ray or CT, which primarily show bone.

Question 19

Name the six official DXI (diagnostic imaging interpretation) case categories tested on Part III.

Accepted Answer

Arthritic, congenital/skeletal variants, trauma, tumors, miscellaneous osteoarticular, and soft tissue - each DXI case presents an image and asks for interpretation within one of these categories.

Question 20

A patient has a complex, comminuted fracture on X-ray, and the surgeon needs precise 3D bony detail before planning fixation. Which imaging study is ordered next?

Accepted Answer

CT scan - it provides superior bony detail and multiplanar reconstruction for complex fracture patterns compared to a plain film X-ray.

Question 21

A patient with a history of breast cancer presents with new, unexplained multifocal bone pain. Which imaging study screens the entire skeleton for metastatic lesions?

Accepted Answer

A bone scan (radionuclide scintigraphy) - it is sensitive for detecting metastatic or infectious bone lesions across the whole skeleton in a single study.

Question 22

Which two inflammatory lab markers are commonly ordered together to screen for systemic inflammation, and which one changes faster?

Accepted Answer

ESR (erythrocyte sedimentation rate) and CRP (C-reactive protein) - CRP rises and falls faster, making it more useful for tracking acute changes, while ESR better reflects more chronic inflammation.

Question 23

A young adult with inflammatory-pattern low back pain and asymmetric peripheral joint involvement tests positive for which genetic marker associated with spondyloarthropathies?

Accepted Answer

HLA-B27 - it is strongly associated with ankylosing spondylitis and related spondyloarthropathies, supporting an inflammatory rather than mechanical diagnosis.

Question 24

Which lab test specifically supports a diagnosis of rheumatoid arthritis when a patient presents with symmetric small-joint polyarthritis?

Accepted Answer

Rheumatoid factor (RF) - combined with anti-CCP antibody testing, a positive RF supports rheumatoid arthritis, helping distinguish it from other causes of joint pain.

Question 25

What combination of findings defines cauda equina syndrome, and how urgently must it be managed?

Accepted Answer

Saddle anesthesia, bowel or bladder dysfunction, and bilateral leg weakness or pain - this is a surgical emergency requiring immediate emergency department referral, not conservative treatment.

Question 26

An elderly patient reports back pain, and the exam reveals a pulsatile, expansile abdominal mass. What life-threatening diagnosis must be ruled out?

Accepted Answer

Abdominal aortic aneurysm - a pulsatile abdominal mass with back pain requires immediate emergency referral for imaging, since rupture is life-threatening.

Question 27

A patient becomes dizzy with cervical rotation and extension and also reports diplopia and dysarthria. What serious vascular condition do these '5 Ds and 3 Ns' signs suggest, and what should the clinician do?

Accepted Answer

Vertebrobasilar insufficiency (VBI) - any of these signs (dizziness, diplopia, dysarthria, dysphagia, drop attacks, nausea, nystagmus, numbness) means the clinician should stop and avoid cervical manipulation, then refer.

Question 28

How can a clinician distinguish mechanical low back pain from inflammatory back pain based on symptom pattern alone?

Accepted Answer

Mechanical pain worsens with activity and improves with rest, while inflammatory pain improves with activity and comes with prolonged morning stiffness of over 30 minutes, typically starting before age 40.

Question 29

A patient has leg pain that follows a clear dermatomal band below the knee and a positive nerve tension sign. Is this radicular or referred pain, and how do you know?

Accepted Answer

Radicular pain - it follows a specific dermatomal pattern, travels below the knee, and reproduces with nerve tension testing, whereas referred (sclerotomal) pain is vaguer and usually stays above the knee.

Question 30

A patient shows progressive hand clumsiness, gait imbalance, hyperreflexia, and a positive Hoffmann's sign. What condition do these upper motor neuron signs suggest?

Accepted Answer

Cervical myelopathy - spinal cord compression produces upper motor neuron signs such as hyperreflexia, spasticity, and positive pathological reflexes, and it requires prompt referral for imaging and possible surgical evaluation.

Question 31

A patient with a history of intravenous drug use presents with fever and severe, unrelenting focal spinal pain. What infectious diagnosis must be considered?

Accepted Answer

Discitis or vertebral osteomyelitis - fever plus focal spinal pain in an at-risk patient requires urgent referral for imaging and labs, not spinal adjustment.

Question 32

Which chiropractic technique system uses a high-velocity, low-amplitude thrust and is the most broadly taught approach across the profession?

Accepted Answer

Diversified technique - it is a general HVLA system applied across the spine and extremities and forms the foundation most chiropractic students learn first.

Question 33

Which technique system relies on a specific listing system and X-ray-based line-of-drive analysis to plan a highly segment-specific adjustment?

Accepted Answer

Gonstead technique - it emphasizes detailed biomechanical analysis, including static and motion palpation plus X-ray line-marking, to determine listings before a specific-contact adjustment.

Question 34

A patient prefers a low-force approach, and the clinician uses a handheld, spring-loaded instrument to deliver the adjustment. What technique is this?

Accepted Answer

Activator Methods - it delivers a controlled, low-force, high-velocity impulse through an instrument rather than a manual thrust, often preferred for sensitive or acute presentations.

Question 35

Which technique uses a segmented drop-piece table that releases just as the clinician delivers a light thrust to the segment?

Accepted Answer

Thompson (drop-table) technique - the table drop reduces the force needed from the practitioner while still delivering a fast, specific segmental adjustment.

Question 36

Which technique uses a specialized table that flexes and distracts the lumbar spine, and is favored for disc herniation or spinal stenosis cases?

Accepted Answer

Flexion-distraction (Cox technique) - the rhythmic flexion-distraction motion is designed to reduce intradiscal pressure and widen the intervertebral foramen, making it well suited to disc and stenosis cases.

Question 37

Name three absolute contraindications to spinal adjustment at a given segment.

Accepted Answer

Fracture, malignancy, or active infection at the site of the intended adjustment - any of these means the clinician should never adjust that segment.

Question 38

A patient on anticoagulant therapy needs cervical adjustment, and during setup develops dizziness and nystagmus. What should the clinician do, and how does this differ from the anticoagulant issue alone?

Accepted Answer

Stop immediately and refer - dizziness and nystagmus are VBI warning signs and an absolute stop, whereas anticoagulant therapy alone is only a relative contraindication requiring caution and technique modification, not automatic avoidance.

Question 39

In the first 48 to 72 hours after an acute soft-tissue injury, which physical modality is preferred to control inflammation and swelling?

Accepted Answer

Cryotherapy (ice) - cold reduces acute inflammation, swelling, and pain, while heat (thermotherapy) is reserved for chronic stiffness once the acute inflammatory phase has passed.

Question 40

Which supportive modality applies a pulling force to the spine to reduce disc pressure and widen the intervertebral foramen?

Accepted Answer

Mechanical traction - it is used to decompress discs and neural foramina, commonly for radiculopathy or disc-related complaints.

Question 41

What is the primary clinical purpose of interferential current (IFC) or electrical muscle stimulation in supportive care?

Accepted Answer

Pain modulation and muscle stimulation - the electrical current helps gate pain signals and can stimulate muscle contraction to reduce guarding and spasm.

Question 42

Beyond passive modalities, what active supportive interventions help patients build long-term resilience against re-injury?

Accepted Answer

Therapeutic and rehabilitative exercise, stabilization training, and nutrition or lifestyle counseling - active care builds strength and function rather than just providing symptomatic relief.

Question 43

What three elements must a chiropractic treatment plan specify for a new patient?

Accepted Answer

Frequency of care, expected duration, and measurable functional goals - a treatment plan without these is difficult to justify or reassess.

Question 44

Why is scheduled re-evaluation an essential part of case management, even when a patient reports feeling better?

Accepted Answer

It objectively confirms whether the treatment plan is working using standardized outcome measures, and it determines whether to continue, modify, discharge, or refer the patient.

Question 45

Name two situations during ongoing care that should trigger a referral out of the chiropractic office.

Accepted Answer

The emergence of red flags, such as a progressive neurologic deficit or signs of systemic disease, or failure to respond to a reasonable trial of conservative care - both indicate the case needs management beyond chiropractic care alone.

Question 46

What does the SOAP format stand for in clinical documentation, and why does it matter for case management?

Accepted Answer

Subjective, Objective, Assessment, Plan - this structure documents the patient's report, exam findings, clinical impression, and next steps, supporting continuity of care and legal defensibility.

Question 47

What compression-to-breath ratio is used during single-rescuer adult CPR?

Accepted Answer

30 compressions to 2 breaths - this ratio is maintained until an AED arrives, advanced help takes over, or the patient shows signs of life.

Question 48

What does the FAST mnemonic prompt a clinician to check when stroke is suspected in a patient?

Accepted Answer

Face drooping, Arm weakness or drift, Speech difficulty, and Time to call emergency services immediately - recognizing these signs quickly matters because stroke treatment is time-sensitive.

Question 49

Before starting a course of chiropractic care, what must a clinician obtain from the patient regarding risks, benefits, and alternatives?

Accepted Answer

Informed consent - the patient must understand the nature of care, material risks, expected benefits, and alternatives to treatment before care begins.

Question 50

What does 'maximum therapeutic benefit' (MTB) mean when planning discharge from active care?

Accepted Answer

The point at which further treatment is not expected to produce additional functional improvement - reaching MTB signals it is time to discharge, transition to maintenance or wellness care, or refer elsewhere.
