Question 1

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

Accepted Answer

A)Open-angle glaucoma tends to be a chronic and gradually progressive disease. It typically affects both eyes, although the pressures and progression may not be symmetric. Patients with angle-closure glaucoma may have intermittent episodes lasting several hours before they have a more typical prolonged attack of angle-closure glaucoma. Because of the effect of pupil dilation on aqueous outflow in angle-closure glaucoma, episodes often occur in association with darkness, emotional upset, or other factors that cause the pupil to dilate.

Question 2

What is conductive hearing loss?

Accepted Answer

A)Conductive hearing loss is any disruption of the transmission of sound from the external auditory meatus to the inner ear. Sensorineural hearing loss is a decrease or distortion in the ability of the inner ear to receive and interpret auditory stimuli. Damage to the hair cells of the organ of Corti is a significant cause of sensorineural hearing deficit. Degeneration of the hair cells of the cochlea is involved in progressive sensorineural hearing loss with aging, called presbycusis.

Question 4

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 7

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

A)Tobramycin, an aminoglycoside antibiotic, is used in the treatment of advanced bacterial infections and for the treatment of tuberculosis. A potential serious adverse effect of this class of medication is ototoxicity, affecting the client's hearing. The nurse should plan on teaching the client how to self-monitor for hearing loss. Total communication and cued speech are approaches to enhancing communication with clients who have a hearing deficit. It is not important for the client to understand the actions and drug interactions of the group of drugs to which tobramycin belongs.

Question 8

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

A)If vision impairment is significant, the infant should undergo surgical removal of the cataract within the first 2 months of life. For children older than 2 months, cataract surgery should be performed at the discretion of the healthcare provider. The asymptomatic 2-month-old infant is not displaying signs of significant vision impairment, but the 1-month-old infant is. The 3- and 6-month-old infants are showing signs of vision impairment but are both at an age at which surgery may only be performed if the healthcare providers decides it is necessary.

Question 11

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

Accepted Answer

A)Age is the greatest single risk factor for cataracts. Environmental and lifestyle factors, such as long-term exposure to sunlight, increase the risk for cataracts; cigarette smoking and heavy alcohol consumption are associated with earlier cataract development. This client's age would indicate a predisposition for cataract formation, but not hypertension or only moderate alcohol use. Being a smoker would indicate such a predisposition, but this is still not as great a risk factor as the client's age.

Question 13

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 14

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

A)The removal of fall hazards from the client's home and provision of additional lighting best demonstrates providing a safe environment for the client following surgery. It's important for the client to understand what self-care activities are necessary, and it's good that the client's close family members are aware of the self-care instructions the client has received and that the client's employer doesn't expect an immediate return to standard duties, but these don't relate directly to providing a safe environment.

Question 16

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

A)Because systemic absorption may occur with beta blockers, the nurse should teach the client to close the eyes and occlude the lacrimal duct after administration to help reduce systemic absorption. The simplest way to provide this teaching in a way the client will readily understand is by instructing the client to close the eyes. Using terms such as "occlude your lacrimal duct," "guard against systemic absorption," or "use punctal occlusion" require additional explanation to be properly understood by the client.

Question 17

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

A)The nurse should respond that cataracts tend to occur in both eyes and develop at different rates, and one cataract generally matures more rapidly than the other. The nurse should not tell the client that the healthcare provider is the only one who can tell if the client has a cataract in the left eye. The lack of vision changes in the left eye does not necessarily indicate the severity of the condition, and surgery might not be necessary for either eye.

Question 18

Which of the following best describes tinnitus?

Accepted Answer

A)Tinnitus is the perception of sound or noise in the ears without stimulus from the environment. The sound may be steady, intermittent, or pulsatile and is often described as a buzzing, roaring, or ringing. It would not be ringing accompanying the perception of high-frequency tones because such a perception would involve external auditory stimuli. Lack of auditory perception of external auditory stimuli is lack of hearing. Tinnitus does not involve perception of visual stimuli as auditory.

Question 19

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

A)Anxiety is a common response to a new diagnosis of glaucoma. Here, the most appropriate intervention would be for the nurse to support the client's use of coping mechanisms. Although referral to a psychologist may be necessary at some point, it typically is not an initial course of action. Assuring the client there is nothing to be afraid of minimizes the client's concerns and is not appropriate. Turning off the lights is not an intervention that will lessen the client's anxiety.
