Practice Q & A- Eyes & Ears Exam 5 Med Surg

A client's relative asks the nurse what a cataract is. What explanation should the nurse provide? 1 An opacity of the lens 2 A thin film over the cornea 3 A crystallinization of the pupil 4 An increase in the density of the conjunctiva

A nurse is caring for a client who is scheduled for surgery for a detached retina. Which goal of surgery identified by the client indicates that the preoperative teaching was effective? 1 Promote growth of new retinal cells 2 Adhere the sclera to the choroid layer 3 Graft a healthy piece of retina in place 4 Create a scar that aids in healing retinal holes

A nurse is developing a teaching plan for a client with otosclerosis. What information should the nurse include in the teaching plan? 1 Stapedectomy is the procedure of choice. 2 Hearing aids usually restore some hearing. 3 The client is usually unable to hear bass tones. 4 Air conduction is more effective than bone conduction.

2 With a partial hearing loss the auditory ossicles have not yet become fixed; as long as vibrations occur, a hearing aid may be beneficial.

What should the nurse do for a client who just had cataract surgery? 1 Instruct the client to avoid driving for several weeks. 2 Teach the client coughing and deep-breathing techniques. 3 Advise the client to refrain from vigorous brushing of the teeth and hair. 4 Encourage the client to perform eye exercises to strengthen the ocular musculature.

3 Activities such as rigorous brushing of hair and teeth cause increased intraocular pressure and may lead to hemorrhage in the anterior chamber.

A client with glaucoma asks a nurse about future treatment and precautions. What information should the nurse's explanation include? 1 Avoidance of cholinergics 2 Surgical replacement of lens 3 Continuation of therapy for life 4 Prevention of high blood pressure

3 Therapy

Which desired effect of therapy should the nurse explain to the client who has primary angle-closure glaucoma? 1 Dilating the pupil 2 Resting the eye muscles 3 Preventing secondary infection 4 Controlling intraocular pressure

4 Glaucoma is a disease in which there is increased intraocular pressure resulting from narrowing of the aqueous outflow channel (canal of Schlemm). This can lead to blindness, caused by compression of the nutritive blood vessels supplying the rods and cones.

Which clinical indicator is the nurse most likely to identify when exploring the history of a client with open-angle glaucoma? 1 Constant blurring 2 Abrupt attacks of acute pain 3 Sudden, complete loss of vision 4 Impairment of peripheral vision

4 Open-angle glaucoma has an insidious onset, with increased intraocular pressure causing pressure on the retina and blood vessels in the eye. Peripheral vision is decreased as the visual field progressively diminishes.

A client is scheduled for a labyrinthectomy to treat Ménière syndrome. What expected outcome of the procedure should be included in preoperative teaching? 1 Absence of pain 2 Decreased cerumen 3 Loss of sense of smell 4 Permanent irreversible deafness

4 The labyrinth is the inner ear and consists of the vestibule, cochlea, semicircular canals, utricle, saccule, cochlear duct, and membranous semicircular canals. A labyrinthectomy is performed to alleviate the symptom of vertigo but results in deafness, because the organ of Corti and cochlear nerve are located in the inner ear.

A nurse is caring for an older adult with a hearing loss secondary to aging. What can the nurse expect to identify when assessing this client? Select all that apply.

Answer: 1, 3. 1 Cerumen (ear wax) becomes drier and harder as a person ages. 2 There is no greater incidence of tympanic tears caused by the aging process. 3 Generally, female voices have a higher pitch than male voices; older adults with presbycusis (hearing loss caused by the aging process) have more difficulty hearing higher-pitched sounds. 4 The hair in the auditory canal increases, not decreases. 5 The epithelium of the lining of the ear becomes thinner and drier.
