Question 20: A patient with a symptomatic neck mass refuses biopsy despite counseling. What is the best documentation practice?

Note 'patient noncompliant' only
Do not document to avoid liability
Document the discussion of risks of refusal, patient capacity, and the patient's decision (informed refusal) (Correct answer)
Discharge the patient from the practice immediately

Correct answer: Document the discussion of risks of refusal, patient capacity, and the patient's decision (informed refusal)

Informed refusal documentation should include the risks explained, decision-making capacity, and the patient's choice.

Question 21: In the floor of mouth, how does the lingual nerve relate to Wharton's (submandibular) duct?

It pierces the duct wall
It runs only above the duct, parallel to it
It runs entirely medial to the duct without crossing it
It loops under the duct, passing from lateral to medial (Correct answer)

Correct answer: It loops under the duct, passing from lateral to medial

The lingual nerve crosses under Wharton's duct from lateral to medial, so it is at risk during duct and gland surgery.

Question 22: Which nerve supplies the tensor tympani muscle?

Glossopharyngeal nerve
Mandibular division of the trigeminal nerve (Correct answer)
Facial nerve
Vagus nerve

Correct answer: Mandibular division of the trigeminal nerve

The tensor tympani comes from the first pharyngeal arch and is supplied by V3 through the nerve to the medial pterygoid.

Question 23: Which semicircular canal is most commonly involved in benign paroxysmal positional vertigo?

Posterior (Correct answer)
Common crus
Horizontal (lateral)
Superior (anterior)

Correct answer: Posterior

Gravity makes otoconia settle mostly in the posterior canal, which is diagnosed with Dix-Hallpike and treated with the Epley maneuver.

Question 24: Which test is used to assess Eustachian tube function and middle ear pressure?

Rinne test
Tympanometry (Correct answer)
Pure tone audiometry
Otoscopy

Correct answer: Tympanometry

Tympanometry is an objective test used to assess the function of the middle ear, including the Eustachian tube and the mobility of the tympanic membrane (eardrum). It measures how the eardrum moves in response to changes in air pressure in the ear canal. This helps diagnose conditions like middle ear fluid, Eustachian tube dysfunction, or perforations of the eardrum, providing valuable information about middle ear health.

Question 25: How should assessment and evaluation knowledge be maintained and updated?

Learning stops after certification
Through continuous professional development, current literature review, and professional networking (Correct answer)
Knowledge updates are only needed every five years
Initial training provides lifelong competence

Correct answer: Through continuous professional development, current literature review, and professional networking

Professional competence requires ongoing development through education, literature review, and engagement with the professional community.

Question 26: Which mitochondrial mutation makes patients highly susceptible to aminoglycoside-induced hearing loss?

MT-RNR1 m.1555A>G (Correct answer)
COL4A5
SLC26A4
GJB2 35delG

Correct answer: MT-RNR1 m.1555A>G

The m.1555A>G variant in the mitochondrial 12S rRNA gene makes ribosomes bind aminoglycosides more easily, which can cause deafness even after one dose.

Question 27: Which organization provides the umbrella standards that ABOHNS follows for its Continuing Certification program?

ABOHNS is an ABMS member board, and ABMS sets the shared standards for continuing certification across member boards.

Question 28: Which tongue muscle is NOT supplied by the hypoglossal nerve?

Genioglossus
Hyoglossus
Palatoglossus (Correct answer)
Styloglossus

Correct answer: Palatoglossus

The palatoglossus is supplied by the vagus nerve through the pharyngeal plexus; all other intrinsic and extrinsic tongue muscles get CN XII.

Question 29: How should challenges in communication and documentation be addressed?

Apply systematic problem-solving, seek expert guidance when needed, and document decisions (Correct answer)
Avoid challenges and stick to familiar tasks
Ignore challenges until they resolve themselves
Delegate all challenges to supervisors
