The mother of a 2-year-old toddler is concerned about the upcoming placement of tympanostomy tubes in her son's ears. The nurse would include which of these statements in the teaching plan?
The purpose of the tubes is to decrease the pressure and allow for drainage.
The tubes are permanently inserted during a surgical procedure.
The tubes are placed in the inner ear.
The tubes are used in children with sensorineural loss.
The Correct Answer is A
A. The purpose of the tubes is to decrease the pressure and allow for drainage: Tympanostomy tubes are placed in the tympanic membrane to facilitate drainage of middle ear fluid and equalize pressure. They help prevent recurrent otitis media and improve hearing in children prone to persistent effusions. The tubes create a temporary opening that allows air to enter the middle ear, reducing the risk of fluid accumulation and infection.
B. The tubes are permanently inserted during a surgical procedure: Tympanostomy tubes are not permanent; they usually fall out on their own within 6 to 12 months as the tympanic membrane heals. In some cases, if they do not extrude naturally, they may need to be removed by an ear, nose, and throat (ENT) specialist. Permanent tubes are rarely used and only in cases of severe chronic ear problems.
C. The tubes are placed in the inner ear: Tympanostomy tubes are inserted into the tympanic membrane (eardrum), which separates the outer ear from the middle ear. They do not enter the inner ear, which contains the cochlea and vestibular system. Placement in the inner ear would not be anatomically correct and could lead to serious complications.
D. The tubes are used in children with sensorineural loss: Tympanostomy tubes are not a treatment for sensorineural hearing loss, which results from damage to the inner ear or auditory nerve. They are used for conductive hearing issues caused by middle ear effusion, recurrent ear infections, or Eustachian tube dysfunction. Sensorineural hearing loss is typically managed with hearing aids or cochlear implants, not tympanostomy tubes.

Correct Answer is B
Explanation
A. Maxillary sinuses reach full size after puberty: While maxillary sinuses continue to grow throughout childhood, they are present at birth and reach adult size during late adolescence. The frontal and sphenoid sinuses, rather than the maxillary, experience more significant postnatal development.
B. Maxillary and ethmoid sinuses are the only sinuses present at birth: At birth, only the maxillary and ethmoid sinuses are developed. The frontal and sphenoid sinuses begin to develop later in infancy and childhood, with full maturation occurring in adolescence.
C. Frontal sinuses are fairly well developed at birth: Frontal sinuses do not develop until around 7 to 8 years of age and continue growing into adolescence. They are absent or rudimentary in newborns.
D. Sphenoid sinuses are full size at birth: The sphenoid sinuses begin developing around 2 to 3 years of age and continue growing into late childhood and adolescence. They are not present at birth.
Correct Answer is ["A","D"]
Explanation
A. Intercostals: The intercostal muscles, including the external and internal intercostals, are primary muscles of respiration. They play a crucial role in expanding and contracting the thoracic cavity during inhalation and exhalation, facilitating airflow into and out of the lungs.
B. Scalene: The scalene muscles assist in elevating the first two ribs during deep inhalation, making them accessory muscles of respiration rather than primary muscles. They support breathing but are not the main muscles involved in the normal respiratory cycle.
C. Sternomastoid: The sternocleidomastoid muscles are also considered accessory muscles of respiration. They help elevate the sternum during forced inhalation, but they are not classified as primary muscles of respiration, which are more involved in the regular breathing process.
D. Diaphragm: The diaphragm is the primary muscle of respiration and is crucial for normal breathing. It contracts and flattens during inhalation, increasing the volume of the thoracic cavity and allowing air to flow into the lungs. This muscle is essential for the majority of airflow during normal breathing.
E. Pectoralis major: The pectoralis major is primarily involved in shoulder movement and is not a primary muscle of respiration. Although it can assist during forceful inhalation when the arms are raised, it does not function as a main muscle in the respiratory process.
