Question 1

What is conductive hearing loss?

Accepted Answer

Conductive hearing loss occurs when there is a disruption in the transmission of sound from the external auditory meatus (ear canal) to the inner ear. This can be caused by a variety of factors such as earwax buildup, fluid accumulation in the middle ear, or damage to the ear drum or bones in the middle ear.

Question 2

Which assessment finding supports the nurse's conclusion that a client is at risk for cataracts?

Accepted Answer

Age is a significant risk factor for developing cataracts, with the majority of cases occurring in individuals over the age of 60. While hypertension, moderate alcohol use, and smoking can increase the risk of other health problems, they are not specifically linked to the development of cataracts.

Question 3

The nurse is evaluating instructions provided to a client with glaucoma.Which client statement indicates that teaching has been effective?

Accepted Answer

The statement "I must use my eyedrops as prescribed for the rest of my life" indicates that the client understands that glaucoma is a chronic condition that requires ongoing treatment to prevent further damage to the eyes. The other statements reflect misunderstandings about the use of eyedrops for glaucoma.

Question 4

Which of the following best describes tinnitus?

Accepted Answer

Tinnitus is the perception of sound in the absence of external auditory stimuli. It can manifest as ringing, buzzing, hissing, or other sounds.

Question 5

Which assessment finding is consistent with a diagnosis of open-angle glaucoma?

Accepted Answer

Gradual loss of vision in both eyes over time is a classic sign of open-angle glaucoma. The other options do not match the typical presentation of open-angle glaucoma.

Question 6

A nurse is caring for several pediatric clients who are affected by cataracts.Of these clients,which is the most obvious candidate for surgical removal of the cataract?

Accepted Answer

The one-month-old infant with no reaction to bright light and failure to notice toys or faces is the most obvious candidate for surgical removal of the cataract as these symptoms suggest that the cataract is significantly impeding the infant's vision. The other infants have less immediate or severe symptoms and may not require surgical intervention at this time.

Question 7

An older adult client is using prescription eyedrops to treat her glaucoma.When providing client teaching about this medication,which of the following should the nurse mention as potential side effects? Select all that apply.

Accepted Answer

A)The client is taking a prostaglandin analog as eyedrops, which can cause the side effect of a change in iris color. Other potential side effects are blurred vision, eye pain (itching, burning, stinging), and eye redness, but not intermittent eyesight loss, headaches, or clouding of the eyes.

Question 8

The nurse is planning care for a client scheduled for cataract surgery.Which intervention should the nurse include in the plan of care to help provide a safe environment for the client following surgery?

Accepted Answer

Removing fall hazards and providing additional lighting can help prevent falls and promote a safe environment for the client following surgery. While education about self-care activities and informing family members are important parts of care, they do not necessarily directly address the issue of safety concerns after surgery. Ensuring the client's employer does not expect the client to return to standard duties may be important, but it is not as immediately relevant to the client's postoperative safety as removing fall hazards and providing additional lighting.

Question 9

A nurse is caring for a client who is receiving IV tobramycin for the treatment of a respiratory infection.Which of the following should the nurse plan on teaching the client how to do?

Accepted Answer

Tobramycin is an aminoglycoside antibiotic that can cause ototoxicity, which is damage to the ear that can result in hearing loss. Therefore, the nurse should plan on teaching the client to self-monitor for hearing loss and report any changes immediately to the healthcare provider. The other options (A, C, and D) are not directly related to the administration of tobramycin.

Question 10

What is characteristic of conductive hearing loss?

Accepted Answer

A)Conductive hearing loss involves an equal loss of hearing at all frequencies. If the level of sound is greater than the threshold for hearing, speech discrimination is good. Because of this, the patient with a conductive hearing loss benefits from amplification by a hearing aid. Sensorineural hearing loss typically affects the ability to hear high-frequency tones.

Question 11

The nurse is providing teaching to a client who was prescribed an ophthalmic beta blocker for glaucoma.The client is having difficulty understanding how to self-administer the medication.Which instruction by the nurse is best?

Accepted Answer

Instructing the client to close their eyes is the best instruction for self-administering an ophthalmic beta blocker. This ensures that the medication stays in the eye and does not enter the systemic circulation, which can cause adverse effects. The other options (occluding the lacrimal duct, guarding against systemic absorption, using punctal occlusion) may be appropriate for other types of eye medication, but not specifically for beta blockers.

Question 12

Which of the following diagrams would the nurse use when describing open-angle glaucoma to a client?

Accepted Answer

Open-angle glaucoma occurs when there is congestion of the trabecular meshwork, which results in reduced flow of aqueous humor through the canal of Schlemm.

Question 13

An older adult client with bilateral cataracts,arthritis,and a hearing deficit is scheduled for cataract surgery.Which is the priority nursing diagnosis for this client?

Accepted Answer

The priority nursing diagnosis for this client is "Risk for Ineffective Health Maintenance" due to the multiple comorbidities and the need for surgery. The client may have difficulty maintaining good health after the surgery, which requires good communication with the healthcare provider, adherence to medication regimen, and regular follow-up visits. The other nursing diagnoses may also be relevant, but they are secondary to the client's physical health and well-being.

Question 14

A nurse is working with several clients who are experiencing hearing loss.Of these clients,which is the best candidate for a cochlear implant?

Accepted Answer

A client with sensorineural hearing loss from long-term exposure to loud noise is the best candidate for a cochlear implant. Cochlear implants are designed to bypass damaged hair cells in the cochlea and directly stimulate the auditory nerve. Sensorineural hearing loss is caused by damage to these hair cells, and long-term exposure to loud noise can cause this damage. Clients with perforated tympanic membranes, obstructed external ear canals or tumors of the middle ear may benefit from other treatments before considering a cochlear implant.

Question 15

A client has been diagnosed with cataracts of both eyes.The client's vision and activities of daily living have become severely impaired.What collaborative intervention does the nurse anticipate for this client?

Accepted Answer

The nurse should anticipate that the client will require surgical intervention to remove both cataracts. Generally, two separate surgeries will be needed, one for each eye, with a few weeks in between surgeries. In some cases, both cataracts may be removed at the same time, but this would depend on the individual situation and the physician's recommendation. Corrective lenses and eyedrops are not typically effective for treating cataracts that have advanced to the point of severely impaired vision and activities of daily living.

Question 16

The nurse is planning care for a client with glaucoma who is experiencing anxiety as a result of the diagnosis.Which intervention should the nurse select to address this need?

Accepted Answer

Supporting the client's use of coping mechanisms will help the client to manage their anxiety in a healthy way, rather than dismissing their concerns or immediately referring them to a counselor. It is important to encourage the use of healthy coping mechanisms and empower the client to take control of their own well-being.

Question 17

A client is undergoing surgery to manage glaucoma.When providing postoperative teaching to this client,the nurse should emphasize that the client is now at increased risk for which form of cataracts?

Accepted Answer

Secondary cataracts are a common complication of surgery for glaucoma. These cataracts develop as a result of inflammation, scarring, or changes to the eye's natural lens during the surgery. Congenital cataracts are present at birth, radiation cataracts are caused by exposure to radiation, and traumatic cataracts are caused by injury to the eye.

Question 18

Which diagnostic technique is used to confirm the location and extent of cataracts?

Accepted Answer

A)Cataracts are diagnosed on the basis of the patient's history and eye examination. The Snellen and Rosenbaum charts are used. A dilated eye exam with either an ophthalmoscope or slit-lamp examination provides a magnified view of the structures of the eye. Ophthalmoscope examination confirms the diagnosis by identifying the location and extent of a cataract. Revealing a dark area is something that would happen only as the cataract matures. Visually inspecting the optic fundus and using tonometry to measure intraocular pressure are diagnostic tests for glaucoma.

Question 19

A school nurse is identifying students who may have hearing loss.Which student would the nurse be most concerned about?

Accepted Answer

Not being able to follow conversations in everyday settings is a strong indicator of possible hearing loss. Options A and B relate to sensitivity to loud noises, which may be indicative of other issues, such as ADHD or anxiety. Option D may indicate risky listening practices, but does not necessarily suggest hearing loss.

Question 20

After being diagnosed with cataracts,a client believes the right eye has a cataract but not the left eye,as there are no vision changes with the left eye.Which response by the nurse is accurate?

Accepted Answer

Cataracts can develop at different rates, which could result in one eye being more affected than the other. It is important for the client to follow up regularly with their doctor to monitor the progression of the cataracts in both eyes.
