What can cause sleep deprivation in hospitalized patients

Pain, noise, lights, anxiety, frequent assessments, and procedures

What are possible effects of sleep deprivation

Fatigue, irritability, confusion, poor concentration, and reduced coping

What is cultural care deprivation

Loss of familiar cultural, family, spiritual, or communication practices

How can nurses promote normal sleep in the hospital

Cluster care, reduce nighttime noise and light, manage pain, and limit unnecessary awakenings

What is myopia

Nearsightedness; near objects are clearer than distant objects

What is hyperopia

Farsightedness; near vision is more difficult

What is astigmatism

A refractive error causing blurred or distorted vision because light is not focused evenly

What is presbyopia

Age-related decreased ability to focus on close objects or small print

What is the difference between myopia and hyperopia

Myopia affects distance vision; hyperopia mainly affects near vision

What is a cataract

A cloudy area in the eye lens caused by protein changes

What are common signs of cataracts

Cloudy or blurred vision, poor night vision, faded colors, and sometimes double vision

What happens to colors with cataracts

They may appear faded or yellowed

What important modifiable risk factor increases cataract risk

Smoking

What is diabetic retinopathy

Damage to retinal blood vessels caused by diabetes

What can diabetic retinopathy lead to

Progressive vision loss and blindness

What eye conditions are patients with diabetes at increased risk for

Diabetic retinopathy, cataracts, and glaucoma

What nursing teaching is important for diabetic eye health

Regular eye exams, glucose control, and prompt reporting of vision changes

What is glaucoma associated with

Optic nerve damage, often associated with increased intraocular pressure

What test measures intraocular pressure

Tonometry

What is typical of open-angle glaucoma

Gradual, usually painless loss of peripheral vision

What findings suggest acute angle-closure glaucoma

Severe eye pain, headache, halos around lights, nausea, and blurred vision

What is the priority for acute angle-closure glaucoma symptoms

Urgent medical evaluation

What is the main difference between cataracts and glaucoma

Cataracts cloud the lens; glaucoma damages the optic nerve

How should the nurse approach a client with vision loss

Call the client by name and identify yourself.

What should the nurse do before touching a visually impaired client

Explain the intervention first

What should the nurse do if the client has partial vision

Stay within the client's remaining visual field

How should directions be given to a visually impaired patient

give specific information about location and distance

Why should nurses avoid saying “over there”

It provides no useful directional information to a client who cannot see

What should the nurse do before leaving the room

Tell the client you are leaving

How should a food tray be described to a client with vision loss

Describe where each item is located, often with the clock-face method

What is the clock-face method

Describing item locations as positions on a clock, such as “meat at 6 o'clock.”

How should the room be arranged for a patient with vision loss

Keep pathways clear and frequently used items in consistent locations

Should furniture be moved without telling a blind client

no

How should a nurse guide a blind client while walking

Let the client hold the nurse's arm while the nurse walks slightly ahead

What should be explained while guiding a client with vision loss

Stairs, curbs, doors, obstacles, and changes in the environment

How should the nurse position themselves when speaking to a client with hearing loss

Sit and face the client

Why should the nurse avoid covering their mouth

The client may rely on lip-reading and facial cues

How should the nurse speak to a hearing-impaired client

Slowly, clearly, and using brief sentences with simple words

Should the nurse shout at a patient with hearing loss

no

Why should the nurse not shout

Shouting can distort speech and make understanding more difficult

What voice adjustment should be tried before increasing volume

Lower the vocal pitch

Why can lowering vocal pitch help

Age-related hearing loss often affects higher-frequency sounds first

What should be done with background noise

Minimize it

What if the client cannot understand spoken information

Write it down

What device should be encouraged if the patient normally uses one

A hearing aid or other hearing device

When is a sign-language interpreter appropriate

When needed to communicate effectively with a client who uses sign language

When using an interpreter, who should the nurse speak to

Directly to the patient, not the interpreter

What is conductive hearing loss

Aging, loud noise, ototoxic medications, or nerve damage

What is presbycusis

Age-related, usually bilateral hearing loss that commonly affects high-frequency sounds

What are common signs of hearing loss

Asking for repetition, loud TV volume, misunderstanding speech, or turning one ear toward the speaker

What is the difference between conductive and sensorineural hearing loss

Conductive affects outer/middle-ear transmission; sensorineural affects the inner ear or nerv
