Chapter 22: Visual and Auditory
problems Test Questions and Answers
the most common visual problem is? - Answer-refractive error
Refractive error? - Answer-this defect percents light rays from converging into a single focus on the
retina.
the major symptom is blurred vision
The principle refractive errors of the eye can be corrected by the use of lenses in the form of? - Answer-
use of lens
glasses contacts
refractive surgery
surgical implantation of an artificial lens.
Myopia? - Answer-nearsightedness, inability to accommodate for objects at a distance
Hyperopia? - Answer-farsightedness, is an inability to accommodate for near objects.
Presbyopia? - Answer-loss of accommodation associated with age.
,about the age 40
results in an inability to focus on near objects.
Astigmatism? - Answer-irregular corneal curvature. the incoming light rays to be bent unequally.
Corrective glasses can be modified for? - Answer-myopia,hyperopia presbyopia and astigmatism.
Contact lens? - Answer-another way to correct refractive errors.
contact lens need oxygen for the eye to breathe
altered or decreased tear formation can make wearing contact lenses difficult.
In general you need to know whether the patient wears contact lenses and also? - Answer-the pattern
of wear daily versus extended and care practices.
this is to avoid of sight threatening complications
Surgical therapy are designed for? - Answer-to eliminate or reduce the need for eyeglasses or contact
lenses and correct refractive error.
Laser-assisted in situ keratomileusis?
LASIK - Answer-considered for patients with low to moderately high amounts of myopia or hyperopia.
the procedure involves using a laser or surgical blade to crease a flap in the cornea.
Refractive intraocular lens?
implants - Answer-IOL implantation is an option for patients with high degree of myopia or hyperopia. it
involves removal of the patients natural lens and implantation of an IOL which is a small plastic lens to
correct a patients refractive error.
, Phakic intraocular lenses? - Answer-are sometimes referred to as implantable contact lenses.
they are implanted without removing the eyes natural lens.
Severe visual impairment? - Answer-which is defined as the inability to read newsprint even with
glasses.
Legally blind? - Answer-refers to central visual acuity of 20/200 or less in the better eye with correction
or a peripheral visual field of 20 degrees or less.
Almost all blindness comes from? - Answer-the result of common eye disease, including cataracts
glaucoma age-related macular degeneration and diabetic retinopathy.
as a nurse you need to assess? - Answer-how long the patient has had a visual impairment
since recent loss of vision has different implications for nursing care.
determine how the patients visual impairment affects normal functioning.
question the patient about the level of difficulty the patient has when reading a newspaper.
determine the personal meaning that the patient attaches to the visual impairment.
vision loss has affected specific aspects of the patients life.
ability to cope and sources of support.
Nursing implementations to visual impairment include? - Answer-health promotion: encourage patient
to seek help from professional
Acute interventions: provide emotional support and direct care to the patient.
involve the family with the visual loss.
always communicate in a normal conversational tone and matter with the patient and address the
patient
make eye contact it ensures you are speaking to the patient and see facial expressions.
