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.

Answer and Explanation

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 D

Explanation

A. Is shorter than the right lung because of the underlying stomach: The right lung is actually shorter than the left lung due to the position of the liver beneath it, which pushes the right diaphragm higher. The left lung is longer but narrower due to the space occupied by the heart.

B. Primarily consists of an upper lobe on the posterior chest: The left lung has both upper and lower lobes visible on the posterior chest. The lower lobe is larger and occupies most of the posterior lung field, while the upper lobe is primarily seen anteriorly and laterally.

C. Is divided by the horizontal fissure: The horizontal fissure is found in the right lung, separating the upper and middle lobes. The left lung has only one fissure, the oblique fissure, which separates its two lobes.

D. Consists of two lobes: The left lung is divided into an upper and lower lobe by the oblique fissure. Unlike the right lung, which has three lobes, the left lung has only two due to the space occupied by the heart, forming the cardiac notch.

A. Listening as the patient inhales and then going to the next site during exhalation B. Instructing the patient to breathe in and out rapidly while listening to the breath sounds C. If the patient is modest, listening to sounds over his or her clothing or hospital gown D. Listening to at least one full respiration in each location

Correct Answer is D

Explanation

A. Listening as the patient inhales and then going to the next site during exhalation: This method is not ideal because it does not allow the nurse to assess both inhalation and exhalation at each site. It is important to listen to both phases of respiration to evaluate the quality of breath sounds accurately.

B. Instructing the patient to breathe in and out rapidly while listening to the breath sounds: Rapid breathing can alter breath sounds and may not provide an accurate assessment of normal respiratory patterns. The patient should breathe normally to ensure the nurse can correctly evaluate the breath sounds.

C. If the patient is modest, listening to sounds over his or her clothing or hospital gown: It is important to listen directly to the skin to obtain clear breath sounds. Clothing can muffle sounds and interfere with the accuracy of the assessment, so the nurse should ensure that the area is adequately exposed while maintaining the patient's modesty.

D. Listening to at least one full respiration in each location: This is the correct approach to auscultation. By listening to a full breath cycle at each auscultation site, the nurse can accurately assess the quality and characteristics of the breath sounds, including any abnormal findings.
