  • 2. 

    If bone conduction is greater than air conduction, what does that indicate?

    • Conductive hearing loss

    • Sensorineural hearing loss

    • Trauma

    • Infection

    Correct Answer
    A. Conductive hearing loss
    Explanation
    Conductive hearing loss is when the transmission of sound in the pathway from the external to internal ear is disrupted; bone conduction is not impacted because bone conduction skips the external and middle ear. Both trauma and infection are ways in which sensorineural hearing loss can occur.

    Sensorineural hearing loss results from damage to the inner ear, auditory nerve (CN VIII) or auditory areas of the cerebral cortex.

    Which of the following can be causes of abnormal color (pale, red, cyanotic) to the external ear?

    • Vasomotor disorders

    • Fever

    • Hypoxemia

    • Cold weather

    Correct Answer(s)
    A. Vasomotor disorders
    A. Fever
    A. Hypoxemia
    A. Cold weather
    Explanation
    Abnormal color (pale, red, cyanotic) to the external ear can be caused by various factors. Vasomotor disorders can lead to abnormal color changes in the external ear due to the dysfunction of blood vessels. Fever can cause dilation of blood vessels, resulting in redness of the external ear. Hypoxemia, which is a low level of oxygen in the blood, can cause cyanosis, a bluish discoloration of the skin. Cold weather can constrict blood vessels, leading to a pale appearance of the external ear.
