ANP-650 Midterm Study latest update
1.A client is diagnosed with strabismus. Which of the following will the client most likely
experience with this disorder?
1. Nystagmus
2. Diplopia
3. Aphakic vision
4. Ptosis - answers ANS: 2
Diplopia, or double vision, is the primary symptom of strabismus. Nystagmus is a
disorder that causes involuntarily rhythmic movements in the eye. Aphakic vision occurs
when the lens of the eye is removed. Ptosis is drooping of the eyelid.
2.A client is experiencing a gradual blurring of vision in both eyes not associated with
any pain. The nurse suspects the client is experiencing:
1. glaucoma.
2. cataracts.
3. macular degeneration.
4. retinal detachment. - answers ANS: 2
Cataracts occur as the opacity of the lens becomes cloudy, blurring the vision. It occurs
in both eyes but is usually worse in one eye. Gradual eye blurring is not associated with
glaucoma, macular degeneration, or retinal detachment.
3.The nurse should instruct a client, diagnosed with glaucoma, that the purpose of
medication is to:
1. help dry up excess secretions.
2. lower the intraocular pressure.
3. strengthen the muscles of the eye.
4. improve the vision in the eye. - answers ANS: 2
Glaucoma is a disease that relates to the increase of intraocular pressure. The
medication given will decrease this intraocular pressure. Medication for glaucoma is not
used to help dry up excess secretions, strengthen the eye muscles, or improve vision.
4.After surgery to remove a cataract, which of the following should the nurse instruct the
client?
1. Be sure to follow the schedule for the prescribed eyedrop medication.
,2. Sleep on the right side to promote drainage.
3. It is okay to rub the eye because the surgery was on the inside.
4. This is an outpatient procedure, and there are no instructions for the patient. -
answers ANS: 1
Client education is extremely important in the aftercare of cataract surgery. There is a
need to emphasize the postoperative care of eyedrop instillation. The client should not
place any pressure near or on the eye. Postoperative instructions are highly important
for the client having an outpatient surgical procedure.
5.A tonometry test has been performed with a client and the results are 25 mmHg. The
nurse know that:
1. the reading is low and there is no problem.
2. the reading is normal and nothing needs to be done at this time.
3. the results are high and follow-up readings and tests are needed.
4. the results are high and there is no cure to bring the pressure down. - answers ANS:
3
Several reading need to be taken throughout the day to establish the highest reading to
be the treated pressure. Normal intraocular pressure ranges from 12 to 16 mmHg. The
reading of 25 mmHg is not low or normal. Medication can be prescribed to reduce the
pressure.
6.A client has been diagnosed with cataracts. The nurse realizes that the only treatment
for this disorder is?
1. Medical management with eyedrops
2. Surgical removal of the lens
3. Cryopexy
4. Phototherapy - answers ANS: 2
Surgical treatment for cataracts begins when vision is sufficiently impaired. The lens is
removed and the replacement artificial intraocular lens is put in place. Cataracts cannot
be treated with medication alone. Cryopexy and phototherapy are not used to treat
cataracts.
7.Which of the following should the nurse assess in a client diagnosed with open-angle
glaucoma?
1. Degree of lost vision
2. Severity of headaches
3. Amount of blurred vision
4. Date of onset - answers ANS: 1
Open-angle glaucoma is characterized by a gradual increase in pressure and a gradual
loss of vision. Closed-angle glaucoma presents with a sudden onset causing headache,
blurred vision, and eye pain.
8.A client is experiencing little flashes of lights and things floating in the visual field. The
nurse suspects:
1. cataracts.
2. glaucoma.
,3. conjunctivitis.
4. retinal detachment. - answers ANS: 4
Retinal detachment is clinically manifested by flashes and floaters in the visual field.
Flashes of light and floaters are not associated with cataracts, glaucoma, or
conjunctivitis.
9.A client tells the nurse that she sees a shadow that is slowing getting worse in her left
eye. Which of the following should the nurse do?
1. Instruct the client to return home to rest in bed.
2. Encourage the client to continue with normal daily activities.
3. Notify an ophthalmologist.
4. Encourage fluids and normal saline eyedrops. - answers ANS: 3
The nurse should notify an ophthalmologist with the clients symptoms. The onset of a
shadow in the field of vision that will not dissipate is an indication of a detached retina.
Retinal detachments rarely self-repair, and the client will need surgery. The nurse
should not instruct the client to return home to rest in bed. The client should not be
encouraged to continue with normal daily activities. Fluids and saline eyedrops will not
help a detached retina.
10.A client is experiencing a loss of central vision but not a loss of peripheral vision. The
nurse realizes the client should be evaluated for:
1. detached retina syndrome.
2. nystagmus.
3. macular degeneration.
4. conjunctivitis. - answers ANS: 3
Macular degeneration is a deterioration of part of the retina, causing loss of central
vision but not affecting peripheral vision. The loss of central vision is not typically seen
in a detached retina, nystagmus, or conjunctivitis.
11.A client is experiencing redness, burning, itching, and pain of the eyes. The nurse
suspects the client is experiencing:
1. blepharitis.
2. conjunctivitis.
3. keratitis.
4. iritis. - answers ANS: 2
Clinical manifestations of conjunctivitis (pink eye) include watery eyes, redness, itching,
and burning pain. Blepharitis is associated with a sticky exudate. Keratitis is associated
with photophobia. Iritis is associated with blurred vision and photophobia.
12.A client has been diagnosed as being legally blind. The nurse realizes this clients
vision is:
1. 20/200 or less in the better eye with correction.
2. 20/200 or less in the worse eye without correction.
3. 20/100 or less in the better eye without correction.
4. 20/100 or less in the worse eye with correction. - answers ANS: 1
Legal blindness is defined as vision of 20/200 or less on a Snellen chart in the better
eye with correction. The eye needs to have correction in order to be diagnosed as
, legally blind; therefore, the choice of 20/200 in the worse eye without correction would
be incorrect. The vision measurements of the other choices can be corrected with
lenses and would not be categorized as legal blindness.
13.The nurse realizes that the best medication treatment for open-angle glaucoma
would be:
1. timolol (Timoptic) eyedrops.
2. latanoprost (Xalatan) eyedrops.
3. timolol (Timoptic) and Latanoprost (Xalatan) eyedrops.
4. metoprolol oral medication. - answers ANS: 3
For the best effect in the treatment of open-angle glaucoma, timolol (Timoptic) and
latanoprost (Xalatan) should be prescribed together. Metoprolol is not prescribed for
open-angle glaucoma.
1.A client tells the nurse that he does not want to develop macular degeneration like his
mother. Which of the following should the nurse instruct the client as being risk factors
for the development of this disorder? (Select all that apply.)
1. There is greater risk as people age.
2. Women are at greater risk than men.
3. African Americans are at greater risk than Caucasians.
4. Family history of macular degeneration increases risk.
5. Smoking does not increase risk.
6. Alcohol prevents the onset of this disorder. - answers ANS: 1, 2, 4
Recent statistics show that macular degeneration is age related and that women are at
greater risk than men. Family history and smoking are also significant risk factors.
Caucasians are at greater risk than African Americans. Alcohol does not prevent the
onset of this disorder.
2.A client is receiving tests to diagnose glaucoma. Which of the following diagnostic
tests will be used to identify this disorder in the client? (Select all that apply.)
1. Visual acuity
2. Visual field test
3. Tonometry
4. Weber test
5. Rinne test
6. Electroencephalogram - answers ANS: 1, 2, 3
Glaucoma is determined through a comprehensive eye exam including a visual acuity
test, visual fields test, dilated eye exam, and tonometry. The Weber and Rinne tests are
used in an ear assessment. An electroencephalogram is not used to diagnose
glaucoma.
3.A client is diagnosed with ocular cancer. The nurse realizes this client could be
treated with: (Select all that apply.)
1. Enucleation
2. Laser surgery
3. Plaque brachytherapy
4. Block incision
