dizziness

Which term refers to an altered sensation of orientation in space?

nuclear

Which type of cataract is caused by central opacity of the lens?

A slit lamp is

a binocular microscope that magnifies the surface of the eye. A beam of light, narrowed to a slit, is directed at the cornea, facilitating an examination of structures and fluid in the anterior segment of the eye. This examination is used to identify disorders such as corneal abrasions, iritis, conjunctivitis, and cataracts. Options A, B, and D are not used to detect corneal abrasions.

on the affected side by bone conduction.

a client is diagnosed with a conductive hearing loss. When performing a Weber test, the nurse expects that this client will hear sound:

According to federal guidelines

hospices may provide no more than 20% of the aggregate annual patient-days at the inpatient level.

Adrenergic agonists

increase aqueous outflow but primarily decrease aqueous production with an action similar to that of beta-blockers and carbonic anhydrase inhibitors

The auditory brain stem response

is a detectable electrical potential from cranial nerve VIII and the ascending auditory pathways of the brain stem in response to sound stimulation. Electrodes are placed on the patient's scalp and on each earlobe. Patients are instructed to wash and rinse their hair prior to this study but to avoid applying any other hair product.

Refractive surgery

is an elective procedure and is considered a cosmetic procedure (to achieve clear vision without the aid of prosthetic devices). It is performed to reshape the cornea for the purpose of correcting all refractive errors. Refractive surgery will not alter the normal aging process of the eye. Clients with conditions that are likely to adversely affect corneal wound healing (corticosteroid use, immunosuppression, elevated intraocular pressure) are not good candidates for the procedure. The corneal structure must be normal and refractive error stable.

A myringotomy (i.e., tympanotomy)

is an incision in the tympanic membrane. Under microscopic guidance, an incision is made through the tympanic membrane to relieve pressure and to drain serous or purulent fluid from the middle ear.

anorexia- cachexia syndrome

is characterized by disturbances in carbohydrate, protein, and fat metabolism; endocrine dysfunction; and anemia. The syndrome results in severe asthenia (loss of energy).

The aim of all glaucoma treatment

is prevention of optic nerve damage. Although treatment cannot reverse optic nerve damage, further damage can be controlled. Reattachment of the retina is not part of glaucoma treatment.

vision pathway to the brain

optic nerve

optic nerve 4

The accompanying illustration depicts the neural pathway for vision. Which of the numbered areas is responsible for receiving the stimulus from the retina?

The radiation dosage

is dependent on the sensitivity of the target tissues to radiation and on the tumor size. The lethal tumor dose is defined as the dose that will eradicate 95% of the tumor yet preserve normal tissue.

lung sounds

A client has received several treatments of bleomycin. It is now important for the nurse to assess

Myringotomy

A patient has serous otitis media with significant hearing loss in the right ear. The patient states, "I have not been able to hear for 2 months." What procedure does the nurse anticipate preparing the patient for?

Blurred distance vision.

Provide time for the patient to discuss her concerns.

A patient is admitted for an excisional biopsy of a breast lesion. What intervention should the nurse provide for the care of this patient?

Wash and rinse hair before test but do not apply any other hair products.

A patient is scheduled to have an auditory brain stem response in 2 days. What does the nurse instruct the patient to do in preparation for the test?

Beta-blockers

decrease aqueous humor production.

Dizziness may be associated

with inner ear disturbances. Vertigo is the illusion of movement wherein an individual senses that they or their surroundings are moving. Tinnitus refers to a subjective perception of sound with internal origin. Nystagmus refers to involuntary rhythmic eye movement.

Alterations in carbohydrate, fat, and protein metabolism Endocrine dysfunction Anemia

A patient near the end of life is experiencing anorexia-cachexia syndrome. What characteristics of the syndrome does the nurse recognize?

An antifibrinolytic agent

, aminocaproic acid (Amicar), stabilizes clot formation at the site of hemorrhage. Corticosteroids, antiplatelets, and diuretics do not have this action. Aspirin is contraindicated.

During an ophthalmic assessment

, the nurse should examine the appearance of the external eye and the pupil responses in the client. A qualified examiner determines internal eye function, visual acuity, and intraocular pressure.

During the Weber test

, which tests bone conduction, a client with a conductive hearing loss hears sound on the affected side by bone conduction. Hearing sound on the unaffected side by bone conduction occurs in sensorineural hearing loss. Also, during the Rinne test, the client with sensorineural hearing loss hears sound longer through air conduction than through bone conduction.

"Your doctor can prescribe medications necessary to relieve pain; however; this treatment will not hasten death."

A 25-year-old client with cancer who is experiencing unrelieved pain rated a 9 on the pain scale requests that the hospice nurse induce a state of unconsciousness until the client dies. Which statement by the nurse demonstrates an understanding of a key difference between conscious sedation and euthanasia?

various diagnostic studies

A barium study is an example of fluoroscopy, which is used to show continuous x-ray images on a monitor, allowing the movement of a body structure to be viewed. Fluoroscopy does not involve the biopsy of tissue samples. Nuclear imaging, not a barium study, uses IV tracers to reveal tumor hot spots. CT scans provide three-dimensional cross-sectional views of tissues to determine tumor density, shape, size, volume, and location as well as highlighting blood vessels that feed the tumor.

Which cardiovascular findings indicate to the nurse that the condition of the dying client is worsening?

Earlier, a client with failing cardiac function exhibits a higher pulse as the body attempts to circulate oxygen. Next, cardiac output is decreased due to ineffective filling of the chambers, impairing circulation, and diminishing the heart's own oxygen supply. The heart rate and blood pressure then decrease. Peripheral circulation is impaired with the feet and ankles becoming pale and mottled.

How does a nurse who has been providing home care to a terminally ill client know that the client's condition is beginning to deteriorate?

Failing cardiac function is one of the first signs that a client's condition is worsening. At first, heart rate increases in a futile attempt to deliver oxygen to cells. The apical pulse rate may reach 100 or more beats/minute. In clients who are dying, the skin becomes pale or mottled, nail beds and lips may appear blue, and the client may feel cold. In clients who are dying, urine volume decreases, and the jaw and facial muscles relax.

bed rest

Nursing management of the client with acute symptoms of benign paroxysmal positional vertigo includes

apical pulse reaches 100 beats per minute

How does a nurse who has been providing home care to a terminally ill client know that the client's condition is beginning to deteriorate?

The client states he cannot read the letter at the top of the chart. What action should the nurse do next? (Snellen chart)

If the client cannot read the top letter of the Snellen chart, then the nurse needs to determine whether the client can count fingers. If the client can count fingers, then the nurse will hold up a random number of fingers, starting 5 feet away, moving forward until the client can clearly count the fingers. A complete visual acuity assessment should be completed before the findings are documented. The tumbling "E" chart is administered in the same fashion as the Snellen chart and is used for people who are illiterate or cannot read the English alphabet. The nurse should not complete an internal eye examination as the next action.

types of awareness

In closed awareness, the patient is unaware of his or her terminal state, whereas others are aware. In suspected awareness, the patient suspects what others know and attempts to find out details about his or her condition. In mutual pretense awareness, the patient, the family, and the health care professionals are aware that the patient is dying, but all pretend otherwise. In open awareness, the patient, the family, and the health care professionals are aware that the patient is dying and openly acknowledge that reality.

Alcohol High-salt foods Monosodium glutamate Caffeine

palliative

Which type of surgery is used in an attempt to relieve complications of cancer?

living will

a type of advance directive I in which the individual documents treatments preferences, instruction for care, accompanied with durable POA for health. also known as medical directive or treatment directive

Cholinergics increase

aqueous fluid outflow by contracting the ciliary muscle, causing miosis, and opening the trabecular meshwork. Beta-blockers decrease aqueous humor production. Alpha-adrenergic agonists decrease aqueous humor production. Carbonic anhydrase inhibitors decrease aqueous humor production.

People who have myopia

are said to be nearsighted. They have deeper eyeballs; thus, the distant visual image focuses in front of, or short of, the retina. Myopic people experience blurred distance vision.

Presbyopia is

associated with aging and results in difficulty with near vision. People with presbyopia hold reading material or handwork at a distance to see it more clearly.

hyphemia

blood in the anterior chamber of the eye in front of the iris

Aerosol inhalation or absorption through the skin

can cause accidental chemotherapy exposure. A nurse must wear a disposable gown and gloves when preparing and administering chemotherapy. She won't absorb chemicals through an intact gown, protective gloves, or goggles.

Mydriatics

cause pupillary dilation. .

Bed rest is recommended

for clients with acute symptoms. Canalith repositioning procedures may be used to resolve attacks of vertigo, and clients with acute vertigo may be medicated with meclizine for 1 to 2 weeks. The Epley procedure is not recommended for clients with acute vertigo. The Dix-Hallpike test is an assessment test used to evaluate for benign paroxysmal positional vertigo.

Exudative retinal detachment results

from the production of a serous fluid under the retina from the choroid from such conditions as uveitis and macular degeneration. Trauma and diabetes (specifically, retinopathy associated with diabetic neovascularization) are associated with rhegmatogenous retinal detachment. Hypertension is associated with retinal vascular occlusion.

Bleomycin

has cumulative toxic effects on lung function. Thus, it will be important to assess lung sounds.

An "in the canal"

hearing aid is used for mild to moderately severe hearing loss. It is cosmetically pleasing but requires good manual dexterity. Refer to Table 50-1 in the text.

Dexamethasone initially

increases appetite and may provide short-term weight gain in some clients

miotics cause

pupillary constriction.

Opacity of the lenses

relates to cataract formation. The main markers of the efficacy of the medication in glaucoma control are lowering of the IOP to the target pressure, appearance of the optic nerve head, and the visual field.

The nurse should advise patients recovering from cataract surgery to eat

soft, easily chewed foods until healing is complete to avoid tearing from excessive facial movements. Eating spinach or collard greens two to four times per week reduces the risk of macular degeneration and increasing the intake of vitamins A and C is essential for preventing cataracts; however, these have no implications on recovery from cataract surgery.

visual acuity

the ability to see fine detail. sharpness of vision

Conductive hearing loss

usually results from an external ear disorder, such as impacted cerumen, or a middle ear disorder, such as otitis media or otosclerosis. In such instances, the efficient transmission of sound by air to the inner ear is interrupted.

Which of the following is the overall aim of glaucoma treatment?

beta blockers

Which of the following medications decreases the production of aqueous humor?

clinicians attitude toward terminally ill

Which of the following remains the greatest barrier to improving end-of-life care?

A nuclear cataract is caused

by central opacity in the lens and has a substantial genetic component. Cortical cataracts involve the anterior, posterior, or equatorial cortex of the lens. Vision is worse in very bright light. Posterior subcapsular cataracts occur in front of the posterior capsule. Near vision is diminished, and the eye is increasingly sensitive to glare from bright light. A subluxated cataract requires the entire lens to be removed, as with a partially or completely dislocated lens.

Vision is usually restored after

cataract surgery with an intraocular lens implant. Contact lenses can be used but can be burdensome for the elderly. Corrective glass lenses can cause a distortion of peripheral vision and only required one lens (over operative eye). To restore vision after cataract surgery, a lens is required.

Snellen chart

chart containing symbols that is used in the testing of visual acuity, sharpness of vision

After obtaining the client's ocular history,

the nurse would test the client's visual acuity. Then the nurse would examine the client's external eye. Direct ophthalmoscopy would follow, and then other examinations, such as a slit-lamp examination, would be done.

Beta blockers decrease

the production of aqueous humor, with a resultant decrease in IOP. Miotics and sympathomimetics decrease the size of the pupil, facilitating the outflow of the aqueous humor, which decreases IOP. Mydriatics dilate the pupil.
