ear disorders test 5
The nurse has notes that the physician has a diagnosis of presbycusis on the client's chart. The nurse plans care knowing the condition is: A. A sensorineural hearing loss that occurs with aging B. A conductive hearing loss that occurs with aging. C. Tinnitus that occurs with aging D. Nystagmus that occurs with aging
A. Presbycusis is a type of hearing loss that occurs with aging. Presbycusis is a gradual sensorineural loss caused by nerve degeneration in the inner ear or auditory nerve.
The nurse is reviewing the physician's orders for a client with Meniere's disease. Which diet will most likely be prescribed? A. Low-cholesterol diet B. Low-sodium diet C. Low-carbohydrate diet D. Low-fat diet
B. Dietary changes such as salt and fluid restrictions that reduce the amount of endolymphatic fluid sometimes are prescribed.
The part of the ear that contains the receptors for hearing is the: A. Utricle B. Cochlea C. Middle ear D. Tympanic cavity
B. The dendrites of the cochlear nerve terminate on the hair cells of the organ of Corti in the cochlea.
The nurse is performing a voice test to assess hearing. Which of the following describes the accurate procedure for performing this test? A.Stand 4 feet away from the client to ensure that the client can hear at this distance. B. Whisper a statement and ask the client to repeat it. C. Whisper a statement with the examiners back facing the client. D. Whisper a statement while the client blocks both ears.
B. The examiner stands 1-2 feet away from the client and asks the client to block one external ear canal. The nurse whispers a statement and asks the client to repeat it. Each ear is tested separately.
A client with Meniere's disease is experiencing severe vertigo. Which instruction would the nurse give to the client to assist in controlling the vertigo? A. Increase fluid intake to 3000 ml a day B. Avoid sudden head movements C. Lie still and watch the television D. Increase sodium in the diet
B. The nurse instructs the client to make slow head movements to prevent worsening of the vertigo. Dietary changes such as salt and fluid restrictions that reduce the amount of endolymphatic fluid sometimes are prescribed. Lying still and watching television will not control vertigo.
During a hearing assessment, the nurse notes that the sound lateralizes to the clients left ear with the Weber test. The nurse analyzes this result as: A. A normal finding B. A conductive hearing loss in the right ear C. A sensorineural or conductive loss D. The presence of nystagmus
C. In the Weber tuning fork test the nurse places the vibrating tuning fork in the middle of the client's head, at the midline of the forehead, or above the upper lip over the teeth. Normally, the sound is heard in equally in both ears by bone conduction. If the client has a sensorineural hearing loss in one ear, the sound is heard in the other ear. If the client has a conductive hearing loss in one ear, the sound is heard in that ear.
When teaching the client about Meniere's disease, which of the following instructions would a nurse give about vertigo? A. Report dizziness at once B. Drive in daylight hours only C. Get up slowly, turning the entire body D. Change your position using the logroll method
C. Turning the entire body, not the head, will prevent vertigo. Dizziness is expected but can be prevented. The client shouldn't drive as he may reflexively turn the wheel to correct vertigo. Turning the client in bed slowly and smoothly will be helpful; logrolling isn't needed.
The ear bones that transmit vibrations to the oval window of the cochlea are found in the: A. Inner ear B. Outer ear C. Middle ear D. Eustachian tube
C. The bones in the middle ear transmit and amplify air pressure waves from the tympanic membrane to the oval window of the cochlea, which is the inner ear. The tympanic membrane separates the other from the middle ear.
