Question 1

A man comes to the emergency department after he had participated in a boxing match,and his left eye is swollen almost shut.He has bruises on his face and neck.He says he is worried because he "can't see well" from his left eye.The physician suspects retinal damage.Signs of retinal detachment include:

Accepted Answer

With retinal detachment,the affected person has shadow or diminished vision in one quadrant or one half of the visual field.

Question 2

When a light is directed across the iris of the eye from the temporal side,the examiner is assessing for:

Accepted Answer

The presence of shadows in the anterior chamber may be a sign of acute angle-closure glaucoma.

Question 3

In using the ophthalmoscope to assess a patient's eyes,the nurse notes a red glow in the patient's pupils.On the basis of this finding,the nurse would:

Accepted Answer

The red glow filling the person's pupil is the red reflex.This is caused by the reflection of the ophthalmoscope light off the inner retina.

Question 4

A 68-year-old woman is in the eye clinic for a checkup.She tells the nurse that she has been having trouble reading the paper,sewing,and even seeing the faces of her grandchildren.On examination,the nurse notes that she has some loss of central vision but her peripheral vision is normal.These findings suggest that:

Accepted Answer

Macular degeneration is the most common cause of blindness.It is characterized by loss of central vision.

Question 5

An ophthalmic examination reveals papilledema.The nurse is aware that this finding indicates:

Accepted Answer

Papilledema,or choked disc,results from increased intracranial pressure caused by a space-occupying mass such as a brain tumour or hematoma.This pressure causes venous stasis in the globe,redness,congestion,and elevation of the optic disc,blurred margins,hemorrhages,and absent venous pulsations.

Question 6

During an ophthalmoscopic examination of a patient,the examiner notes areas of exudate that look like "cotton wool" or fluffy grey-white cumulus clouds.Which of the possible problems below does this finding indicate?

Accepted Answer

Soft exudates or "cotton wool" areas look like fluffy grey-white cumulus clouds.They occur with diabetes,hypertension,subacute bacterial endocarditis,lupus,and papilledema due to any cause.

Question 7

When the retina is examined,which of the following is considered a normal finding?

Accepted Answer

The optic disc is located on the nasal side of the retina.It is a creamy yellow-orange to pink colour.

Question 8

A patient comes into the emergency department after an accident at work.He had not been wearing safety glasses,and a machine had blown dust into his eyes.The nurse examines his corneas by shining a light from the side across the cornea.What findings would suggest that he has suffered corneal abrasion?

Accepted Answer

A corneal abrasion causes irregular ridges in reflected light,producing a shattered appearance of the light rays.

Question 9

The nurse notes the presence of periorbital edema when performing eye assessment on a 70-year-old patient.The nurse will:

Accepted Answer

Periorbital edema occurs with local infections,crying,and systemic conditions such as heart failure,renal failure,allergy,and hypothyroidism.

Question 10

To assess colour vision in a male child,the nurse would:

Accepted Answer

Test only boys for colour vision once between the ages of 4 and 8 years.

Question 11

A patient complains of pain in her right eye.On examination,the nurse sees a pustule at the lid margin that is painful to touch,red,and swollen.The nurse recognizes that this is:

Accepted Answer

A hordeolum,or stye,is a painful,red,and swollen pustule at the lid margin.

Question 12

During an assessment,a patient says that she was diagnosed with open-angle glaucoma 2 years ago.There are various types of glaucoma,such as open-angle glaucoma and closed-angle glaucoma.Which of the following are characteristics of open-angle glaucoma? (Select all that apply. )

Accepted Answer

Open-angle glaucoma is the most common type of glaucoma;there are virtually no symptoms.Vision loss begins with loss of peripheral vision,which often goes unnoticed because individuals learn to compensate intuitively by turning their heads.The other characteristics listed above are those of closed-angle glaucoma.

Question 13

The nurse is assessing a patient's eyes for the accommodation response and would expect to see:

Accepted Answer

The accommodation reaction includes pupillary constriction and convergence of the axes of the eyes.

Question 14

In a patient with anisocoria,the nurse would expect to observe:

Accepted Answer

Unequal pupil size is called anisocoria.It exists normally in 5% of the population but may also be indicative of a central nervous system disease.

Question 15

During a physical education class,a student is hit in the eye with the end of a baseball bat.When examined in the emergency department,the nurse notes the presence of blood in the anterior chamber of the eye.This finding indicates the presence of:

Accepted Answer

Hyphema-blood in the anterior chamber-is a serious result of blunt trauma (from being hit with a fist or a baseball)or spontaneous hemorrhage and may indicate scleral rupture or major intraocular trauma.

Question 16

What would be a normal finding when assessing the lacrimal apparatus during an eye examination?

Accepted Answer

There should be no swelling,redness,or drainage from the puncta.

Question 17

The nurse is performing an eye assessment on an 80-year-old patient.Which of the following findings is considered abnormal?

Accepted Answer

Pupils are small in older adults,so pupillary light reflex may be slow,but pupillary constriction should be symmetrical.

Question 18

A 2-week-old infant can fixate on an object but not follow a light or bright toy.The nurse would:

Accepted Answer

By 2 to 4 weeks,an infant can fixate on an object.By 1 month,the infant should fixate and follow a bright light or toy.

Question 19

When assessing pupillary light reflex,which of the following techniques should the nurse use?

Accepted Answer

To test pupillary light reflex,advance a light in from the side and note the direct and consensual pupillary constriction.

Question 20

The nurse is conducting an eye clinic at the day care centre.When examining a 2-year-old child,if "lazy eye" is suspected,the nurse would:

Accepted Answer

Testing for strabismus is done by performing the corneal light reflex test.The light should be reflected at exactly the same spot in both eyes.
