NBCE Part 2 Chiro Exam Prep Exam Questions & Answers 2026 (21–30)

Question 1

Which of the following tests assesses cranial nerve VIII (vestibulocochlear) function during a head and neck examination?

TheoryPractice · Accepted Answer

Rinne test. The Rinne test compares air and bone conduction of sound and is used to assess the auditory portion of cranial nerve VIII function, helping differentiate between conductive and sensorineural hearing loss.

Question 2

During examination of the temporomandibular joint (TMJ), which finding indicates potential TMJ dysfunction?

TheoryPractice · Accepted Answer

Clicking or crepitus during jaw movement. Clicking or crepitus during jaw movement is a common sign of TMJ dysfunction, often related to disc displacement or articular surface irregularities within the joint.

Question 3

Which of the following properly describes the technique for assessing the corneal reflex?

TheoryPractice · Accepted Answer

Lightly touch the cornea with a wisp of cotton and observe for a blink response. The corneal reflex is tested by lightly touching the cornea with a wisp of cotton, which should elicit a blink response. This tests both the sensory component of cranial nerve V and the motor component of cranial nerve VII.

Question 4

Which finding during examination of the external ear would warrant immediate referral?

TheoryPractice · Accepted Answer

Vesicular eruptions on the auricle and in the ear canal. Vesicular eruptions on the auricle and in the ear canal, especially if accompanied by pain, suggest herpes zoster oticus (Ramsay Hunt syndrome), which requires prompt antiviral treatment to prevent complications.

Question 5

When assessing the maxillary sinuses during a head examination, which technique is most appropriate?

TheoryPractice · Accepted Answer

Palpation for tenderness over the cheeks below the eyes. Palpation for tenderness over the maxillary sinuses (located on the cheeks below the eyes) is the most appropriate direct examination technique to assess for maxillary sinusitis or inflammation.

Question 6

During examination of the tongue, which abnormal finding might indicate hypoglossal nerve (CN XII) dysfunction?

TheoryPractice · Accepted Answer

Deviation to one side upon protrusion. Deviation of the protruded tongue to one side indicates hypoglossal nerve (CN XII) dysfunction on the side to which the tongue deviates, as the functioning muscles on the unaffected side pull the tongue toward the weak side.

Question 7

Which visual field defect would be detected during confrontation testing if a patient has a pituitary tumor compressing the optic chiasm?

TheoryPractice · Accepted Answer

Bitemporal hemianopsia. Bitemporal hemianopsia (loss of the temporal visual fields in both eyes) is the classic visual field defect associated with pituitary tumors that compress the optic chiasm, affecting the crossing fibers from the nasal retina of each eye.

Question 8

Which of the following heart sounds is considered abnormal?

TheoryPractice · Accepted Answer

S4 (fourth heart sound). S1 and S2 are normal heart sounds. S3 can be normal in children and athletes but is abnormal in adults over 40 years of age. S4 is always abnormal and indicates atrial contraction against a stiff ventricle.

Question 9

During percussion of the thorax, a dull sound is most likely to indicate:

TheoryPractice · Accepted Answer

Pleural effusion. Dullness upon percussion typically indicates fluid or solid tissue underlying the percussed area. This could represent pleural effusion, consolidation, or a mass. Normal lung tissue produces resonance, hyperresonance suggests emphysema, and tympany is associated with air-filled cavities.

Question 10

Which auscultatory finding is most characteristic of pneumonia?

TheoryPractice · Accepted Answer

Crackles (rales). Crackles (rales) are typically heard in pneumonia due to fluid in alveolar spaces. Wheezes suggest bronchospasm, pleural friction rubs indicate pleural inflammation, and bronchial breath sounds may be heard over areas of consolidation but aren't the most characteristic finding.
