- A.
Helix
- B.
Antihelix
- C.
Tragus
- D.
Lobe
- E.
Annulus
Correct Answer
E. AnnulusExplanation
The annulus is not an anatomical structure of the external portion of the ear. The helix, antihelix, tragus, and lobe are all parts of the external ear. The helix is the curved rim of the outer ear, the antihelix is the ridge parallel to the helix, the tragus is a small pointed eminence in front of the ear canal, and the lobe is the fleshy lower part of the earlobe. However, the annulus is not a part of the external ear.Rate this question:

Which of the following is not a tiny bone associated with hearing?
- A.
Malleus (hammer)
- B.
Incus (anvil)
- C.
Lagus (wrench)
- D.
Stapes (stirrup)
Correct Answer
C. Lagus (wrench)Explanation
The three bones mentioned in the question, Malleus, Incus, and Stapes, are all tiny bones located in the middle ear that are involved in the process of hearing. However, Lagus is not a bone associated with hearing. The correct bone is actually called the LAGENA, which is a part of the inner ear involved in the sense of hearing in birds and reptiles.Rate this question:

Which ear structure connects the middle ear to the nasopharynx?
- A.
Labyrinth
- B.
Eustachian tube
- C.
Cochlear tube
- D.
Auditory canal
Correct Answer
B. Eustachian tubeExplanation
The Eustachian tube is the correct answer because it is the structure that connects the middle ear to the nasopharynx. This tube helps to equalize the pressure in the middle ear and allows for drainage of fluid from the ear.Rate this question:

Which ear structure is responsible for balance and equilibrium?
- A.
Labyrinth
- B.
Eustachian tube
- C.
Cochlear tube
- D.
Auditory canal
Correct Answer
A. LabyrinthExplanation
The labyrinth is responsible for balance and equilibrium. It is a complex structure located in the inner ear that contains the vestibular system, which includes the semicircular canals and the otolith organs. These structures detect changes in head position and movement, allowing the brain to maintain balance and coordinate body movements. The labyrinth also plays a role in detecting sound, but its primary function is related to balance and equilibrium.Rate this question:

Of the following, which is least likely to cause conductive hearing loss?
- A.
Pus or serum in the middle ear
- B.
Strept infection
- C.
Otitis media
- D.
Otosclerosis (decreased mobility of the ossicles)
Correct Answer
B. Strept infectionExplanation
Strept infection is least likely to cause conductive hearing loss because it primarily affects the throat and tonsils, not the middle ear or the ossicles. Conductive hearing loss is typically caused by issues in the middle ear, such as pus or serum buildup or otitis media. Otosclerosis, which refers to decreased mobility of the ossicles, can also lead to conductive hearing loss. However, strept infection does not directly affect the middle ear or the ossicles, making it the least likely cause of conductive hearing loss among the given options.Rate this question:

Which of the following is least likely to cause sensorineural hearing loss?
- A.
Trauma
- B.
Mastoid brain tumor
- C.
Presbycusis: gradual nerve degeneration
- D.
Otitis media
Correct Answer
D. Otitis mediaExplanation
Otitis media is the least likely to cause sensorineural hearing loss because it is an infection or inflammation of the middle ear, which primarily affects the conductive pathway of hearing. Sensorineural hearing loss, on the other hand, is caused by damage to the inner ear or auditory nerve. Trauma, mastoid brain tumor, and presbycusis are all more likely to cause sensorineural hearing loss as they can directly or indirectly damage the inner ear or auditory nerve.Rate this question:

When you shine the otoscope into the patients ear, where would you see the light reflex?
- A.
2 o’clock in the right ear and 5 o’clock in the left ear.
- B.
5 o’clock in the right ear and 7 o’clock in the left ear.
- C.
1 o’clock in the right ear and 2 o’clock in the left ear.
- D.
3 o’clock in the right ear and 4 o’clock in the left ear.
Correct Answer
B. 5 o’clock in the right ear and 7 o’clock in the left ear.Explanation
The light reflex in the ear is a reflection of light off the eardrum. In a normal ear, the light reflex should be seen at the 5 o'clock position in the right ear and the 7 o'clock position in the left ear. This is because the eardrum is angled slightly in the ear canal, causing the reflection to appear at different positions.Rate this question:

- A.
Nothing, + means that there is nothing wrong
- B.
Trauma
- C.
Cerumen impaction
Correct Answer
B. TraumaExplanation
A (+) Weber test refers to a positive result, indicating that there is a hearing loss or abnormality in the affected ear. Trauma can be a possible factor causing this positive result, as it can lead to damage or injury to the ear. This can disrupt the normal functioning of the ear and result in hearing loss or other abnormalities, leading to a positive Weber test.Rate this question:

What does the Rinne test diagnose?
- A.
Conductive hearing
- B.
Sensorineural hearing
- C.
Air conduction and bone conduction
- D.
Balance
Correct Answer
C. Air conduction and bone conductionExplanation
The Rinne test is a diagnostic test used to evaluate the hearing ability of an individual. It compares air conduction and bone conduction to determine if there is a hearing loss and to differentiate between conductive and sensorineural hearing loss. In the Rinne test, a vibrating tuning fork is placed first on the mastoid bone behind the ear, testing bone conduction, and then near the ear canal, testing air conduction. If air conduction is better than bone conduction, it suggests normal hearing or a sensorineural hearing loss. If bone conduction is better than air conduction, it indicates a conductive hearing loss.Rate this question:

When inspecting the nasal cavity of a patient, you come across and abnormal finding. What is is?
- A.
Septum midline
- B.
Smooth, round masses protruding form the middle meatus
- C.
Nasal mucosa pale red
- D.
Small amount of clear, watery discharge
Correct Answer
B. Smooth, round masses protruding form the middle meatusExplanation
The correct answer is "Smooth, round masses protruding from the middle meatus." This abnormal finding suggests the presence of nasal polyps. Nasal polyps are noncancerous growths that can develop in the lining of the nasal passages or sinuses. They are typically soft and painless, causing symptoms such as nasal congestion, runny nose, and a reduced sense of smell. Treatment options may include medications to reduce inflammation or surgical removal of the polyps.Rate this question:

Which of the following is least likely to cause an enlarge tongue in a patient?
- A.
Candidiasis
- B.
Myxedema
- C.
Down syndrome
- D.
Stomatitis
Correct Answer
A. CandidiasisExplanation
Candidiasis is least likely to cause an enlarged tongue in a patient. Candidiasis is a fungal infection that commonly affects the mouth, but it typically does not cause significant enlargement of the tongue. On the other hand, myxedema, which is a condition caused by severe hypothyroidism, can lead to an enlarged tongue. Down syndrome, a genetic disorder, can also cause an enlarged tongue due to abnormal muscle tone. Stomatitis, which refers to inflammation of the mouth, can sometimes result in tongue enlargement as a secondary effect.Rate this question:
