Front 1

Presbycusis

Back 1

is an age-related change in which progressive hearing loss is caused by loss of hair cells and decreased blood supply in the ear, resulting in a decreased ability to hear high-frequency sounds. Talking in a lower pitch helps with communication.

a subjective noise sensation heard in one or both ears; ringing or tinkling sound in the ear.; caused by toxic levels of Aspirin.

Front 3

Hearing aids are

Back 3

instruments that amplify sounds for conductive hearing loss

Glaucoma medical management includes

Back 4

medical supervision for the rest of life; eyedrops for the rest of life or loss of vision will result.

Common age related changes in vision and hearing are

Which cranial nerves are assessed when assessing the pupils (PERRLA)?

Back 13

III, IV, VI

Front 14

The external eyes are inspected for

Back 14

color and symmetry of the irises.

Front 15

In macular degeneration

Back 15

central vision is gone, and only peripheral vision remains, so it is hard to see things in front of oneself.

Front 16

Abnormal Vision for a snellen chart

Back 16

Vision identified as 20/40 indicated the patient can read at 20 feet what the normal person can see at 40 feet, indicating that the patient has to be closer to read what the normal person can see further away.

Front 17

Atropine is contraindicated for patients with

Back 17

glaucoma.

Front 18

Bactrim patient teaching

Back 18

Report any bruising or bleeding immediately; Report any diarrhea or bloody stools promptly; Report any fever, rash or sore throat promptly; Avoid unprotected exposure to sunlight.

Front 19

Normal vision for a snellen chart

Back 19

20/20, indicated that the individual has normal vision at 20 feet reading the prescribed line.

Front 20

Auditory function can be grossly evaluated using three different assessment tests

Back 20

whisper voice test, Rinne’s test, and Weber’s test.

Front 21

The posterior cavity of the eye is between the

Back 21

lens and retina and contains vitreous humor. This semisolid substance helps keep the retina in place.

Front 22

betaxolol hydrochloride (Betoptic) Side effects/Interventions

Back 22

Hypotension, dizziness, nausea, diaphoresis, headache, fatigue, constipation, and diarrhea are systemic effects of the medication. Nursing interventions include monitoring the blood pressure for hypotension and assessing the pulse for strenght, weakness, irregular rate, and bradycardia.

Front 23

Patient teaching for Amoxil

Back 23

Take with food, Take the entire prescription as prescribed; Report any genital itching to your physician; Report any excess bleeding to your physician.,

Front 24

pilocarpine is used for

Back 24

open angle glaucoma. It works by promoting drainage of the aqueous humor from the anterior chamber of the eye reduces pressure in the eye as the fluid does not build up.

Front 25

Speaking in an unusually quiet or loud voice can indicate

Back 25

hearing loss

Front 26

After a tympanoplasty, the patient should be instructed to

Back 26

avoid excessive movement to prevent dislodging the graft.

Front 27

Meclizine hydrochloride (Antivert)

Back 27

is an antiemetic used to alleviate the nausea that occurs in Meniere's disease from the violent vertigo.

Front 28

tonometry

Back 28

used to assess for internal eye pressure (intraocular pressure).

Front 29

Symptoms of cataract formation may include

Back 29

halos around lights, difficulty reading fine print or seeing in bright light, increased sensitivity to glare such as when driving at night, double or hazy vision, and decreased color vision.

Front 30

Eustachian tube

Back 30

is lined with a mucous membrane that joins the nasopharynx and the middle ear, which equalizes the air pressure on either side of the tympanic membrane.

Front 31

Peripheral vision is tested by

Back 31

Visual field assessment

Front 32

PERRLA

Back 32

is pupils equal, round, and reactive to light and accommodation. Best to assess in a room that is slightly darkened.

Front 33

The most common sign of external otitis is

Back 33

pain along with pruritus (itching).

Front 34

The shape of the lens is changed by the

Back 34

ciliary muscle, which permits the focusing of light from objects at varying distances.

Front 35

Romberg’s test

Back 35

is a simple test to assess vestibular function. If the patient has difficulty maintaining balance or loses balance, it can indicate an inner ear problem. If a fall appears likely, be prepared to support the patient to prevent injury.

Front 36

Bactrim side effects

Back 36

Nausea, vomiting, diarrhea, and loss of appetite may occur. Rare side effects include Steven Johnsons syndrome, blood disorders, liver damage or lung injury.

Front 37

Dexamethasone (Decadron) - Nursing Interventions

Back 37

This drug increases glycogenesis which may lead to hyperglycemia. Therefore the blood sugar level and acetone production must be monitored.

Front 38

Acetazolamide (Diamox)

Back 38

causes excretion of bicarbonate, which would worsen metabolic acidosis. It is used to treat metabolic alkalosis, edema, seizures, and acute glaucoma. A decrease in blood pH would indicate that the client was becoming more acidotic which is life threatening

Front 39

Mannitol (Osmitrol)

Back 39

is an osmotic diuretic that pulls fluid from extravascular spaces into the bloodstream to be excreted in urine. This will decrease intracranial pressure, increase excretion of medications, decrease urine osmolality, and increase serum osmolality.

Front 40

Factors that contribute to cataract development may include

Back 40

age and longer exposure to ultraviolet radiation (sunlight). Other causes are diabetes, smoking, steroids, nutritional deficiencies, alcohol consumption, intraocular infections, trauma, and congenital defects.

Front 41

After a stapedectomy, what is the greatest concern

Back 41

The patient may be dizzy and a fall risk, so use of safety rails can protect the patient. The operative ear is placed upward when lying in bed to prevent pressure or drainage on the site.

Front 42

A triad of symptoms of vertigo, hearing loss, and tinnitus characterizes

Back 42

Ménière’s disease. During an acute attack, safety is the priority. Assist the patient into bed with the side rails up so that the patient does not fall.

Front 43

Myopia

Back 43

is nearsightedness or the ability to see things close up but not far away. This is corrected with concave lenses.

Front 44

Conjunctivitis is

Back 44

very contagious, and hand washing is essential to prevent the spread of it.

Front 45

Controlling diabetes is essential to preventing

Back 45

complication development in patient's with diabetic retinopathy

Front 46

Glaucoma - patient teaching

Back 46

POAG develops bilaterally. The onset is usually gradual and painless, so the patient may not experience noticeable symptoms or, after time, may experience mild aching in the eyes, headache, halos around lights, or frequent visual changes that are not corrected with eyeglasses.
