During an assessment of the ear structures, the nurse would expect to identify which structure as part of the middle ear?
Tympanic Membrane
Ear lobe
Cochlea
Pinna
The Correct Answer is A
Choice a reason:
The tympanic membrane, also known as the eardrum, is a critical component of the middle ear. It is a thin membrane that separates the external ear from the middle ear and vibrates in response to sound waves. These vibrations are then transmitted to the ossicles within the middle ear, which amplify and carry the sound to the inner ear.
Choice b reason:
The ear lobe is part of the external ear, not the middle ear. It is composed of soft skin and fatty tissue and does not play a role in hearing. The ear lobe serves primarily as a site for body decoration such as earrings.
Choice c reason:
The cochlea is a structure located in the inner ear. It is a spiral-shaped organ that contains the organ of Corti, the sensory organ of hearing. The cochlea converts the mechanical vibrations from the middle ear into nerve impulses that are sent to the brain.
Choice d reason:
The pinna, or auricle, is the visible part of the external ear. It is made of cartilage and skin and functions to capture sound waves and direct them into the ear canal towards the tympanic membrane.

Correct Answer is C
Explanation
Choice a reason:
Rhonchi are coarse, rattling respiratory sounds somewhat like snoring, usually caused by obstruction or secretion in the larger airways. They are not considered normal breath sounds and are typically heard in conditions such as chronic bronchitis.
Choice b reason:
Crackles are the sounds you will hear in a lung field that has fluid in the small airways. These sounds are commonly heard in patients with pneumonia, heart failure, and restrictive pulmonary diseases. They are not normal breath sounds.
Choice c reason:
Bronchovesicular sounds are normal breath sounds heard over the main bronchus area and over the upper right posterior lung field. They have a medium pitch and intensity and are heard on both inspiration and expiration. In a healthy individual, these sounds are expected to be heard in the 1st and 2nd intercostal spaces near the sternal body.
Choice d reason:
Tracheal breath sounds are harsh, high-pitched sounds heard when auscultating over the trachea in the neck. They are not normally heard over the intercostal spaces of the chest wall.
Correct Answer is ["A","B","C","D"]
Explanation
Choice a reason:
Wearing nonslip shoes in the house is a preventive measure against falls, which are a leading cause of traumatic brain injuries (TBIs) in adolescents. Nonslip shoes provide better grip and stability, especially on potentially slippery surfaces like tiles or polished wood, reducing the risk of slips and falls that can lead to head injuries.
Choice b reason:
The supervised use of guns by an adult is critical in preventing accidental shootings, which can result in TBIs. Adolescents may lack the maturity and experience to handle firearms safely, and adult supervision ensures that proper safety protocols are followed, reducing the risk of accidental discharge and potential injury.
Choice c reason:
The use of seat belts is one of the most effective ways to prevent TBIs in the event of a vehicle accident. Seat belts restrain the body and prevent individuals from being thrown around inside or ejected from the vehicle, significantly reducing the likelihood of head trauma.
Choice d reason:
Avoiding risky activities such as snowboarding without proper safety equipment is essential in preventing sports-related TBIs. Snowboarding, like other high-speed sports, carries a risk of falls and collisions, which can cause head injuries. Wearing helmets and other protective gear, and engaging in these activities with caution, can mitigate this risk.
