While assessing the eye of an adult client, the nurse observes an inward turning of the client's left eye. The nurse should document the client's esotropia. strabismus. phoria. Exotropia.
A
Normal movement of the eye involves what cranial nerves? (Mark all that apply.) II III IV V VI
A, B, C, E
The functional reflex that allows the eyes to focus on near objects is termed pupillary reflex. accommodation. Refraction. indirect reflex.
B
What is a characteristic symptom of Graves hyperthyroidism? Pterygium Exophthalmos Pinguecula Episcleritis
B
Which of the following assessment findings suggests a problem with the client's cranial nerves? A client states that he has recently begun seeing lights flashing in his field of vision. A client's extraocular movements are asymmetrical and she complains of diplopia. Fundoscopic examination reveals intraocular bleeding. A client's lens appears cloudy and she claims that her visual acuity has recently declined.
B
A client has an abnormal consensual pupillary reaction to light. A nurse understands that what reaction occurs in the client's eyes? Pupils dilate in response to a light shone in the eyes. Eyes do not converge to focus on a shining light. There is no reaction in the opposite pupil to light. Light reflection appears at different spots on both eyes.
C
A client has been diagnosed with astigmatism. The nurse should be prepared to teach the client about which treatment for this condition? Surgery Daily use of eye drops Corrective lenses No night driving
C
A client is assigned a visual acuity of 20/100 in her left eye. Which of the following is true? She obtains a 20% correct score at 100 feet. She can accurately name 20% of the letters at 20 feet. She can see at 20 feet what a normal person could see at 100 feet. She can see at 100 feet what a normal person could see at 20 feet.
C
A nurse examines a client's retina during the ophthalmic examination and notices light-colored spots on the retinal background. The nurse should ask the client about a history of what disease process? Anemia Renal insufficiency Diabetes Retinal detachment
C
The nurse is examining an adult client's eyes. The nurse has explained the positions test to the client. The nurse determines that the client needs further instructions when the client says that the positions test assesses the muscle strength of the eye. assesses the functioning of the cranial nerves innervating the eye muscles. requires the covering of each eye separately. requires the client to focus on an object.
C
The nurse notes that the pupil of a client's left eye constricts when a light is shined into the right eye. How should the nurse document this finding? direct light response present in left eye pupils equal and react to accommodation consensual light response present in left eye consensual light response present in right eye
C
When testing the near reaction, an expected finding includes which of the following? Pupillary dilation on near gaze; dilation on distant gaze Pupillary dilation on near gaze; constriction on distant gaze Pupillary constriction on near gaze; dilation on distant gaze Pupillary constriction on near gaze; constriction on distant gaze
C
A client performs the test for distant visual acuity and scores 20/50. How should the nurse most accurately interpret this finding? Client did not wear his glasses for this test and therefore it is not accurate. When 50 feet from the chart, the client can see better than a person standing at 20 feet. Client can read the 20/50 line correctly and two other letters on the line above. At 20 feet from the chart, the client sees what a person with good vision can see at 50 feet.
D
A client presents to the health care clinic and reports pain in the eyes when working on the computer for long periods of time. The client states that he almost ran into a parked car yesterday because he misjudged the distance from the bumper of his own car. He works for a computer software company and has noticed he is experiencing difficulty reading the manuals that accompany the software he installs for companies. What nursing diagnosis can the nurse confirm based on this data? Ineffective Individual Coping Disturbed Self Concept Self-Care Deficit Risk for Injury
D
A client shares that a first-degree relative has an eye problem, but they not sure what the diagnosis is. What major eye problem will the nurse suggest screening the client for? Retinoblastoma Strabismus Retinitis pigmentosa Glaucoma
D
A nurse notices a middle-aged client in the waiting room pick up a magazine to read while she waits to be seen. She opens the magazine and then extends her arms to move it further from her eyes. Which condition does the nurse most suspect in this client? Exotropia Esotropia Strabismus Presbyopia
D
An adult client visits the clinic and tells the nurse that he has had excessive tearing in his left eye. The nurse should assess the client's eye for viral infection. double vision. allergic reactions. lacrimal obstruction.
D
An older client asks why vision is not as sharp as it used to be when the eyes are focused forward. What should the nurse realize this client is describing? cataracts glaucoma detached retina macular degeneration
D
As part of a physical assessment, the nurse performs the confrontation test to assess the client's peripheral vision. Which test result should a nurse recognize as indicating normal peripheral vision for a client using the confrontation test? Client's consensual pupil constricts in response to indirect light. Eyes converge on an object as it is moved towards the nose. Direct light shown into the client's pupils results in constriction. The client and the examiner see the examiner's finger at the same time.
D
The nurse has tested an adult client's visual fields and determined that the temporal field is 90 degrees in both eyes. The nurse should refer the client for further evaluation. examine the client for other signs of glaucoma. ask the client if there is a genetic history of blindness. document the findings in the client's records.
D
Which technique by the nurse demonstrates proper use of the ophthalmoscope? Uses right eye to examine the client's left eye Moves the scope around so the entire optic disk may be seen Approaches the client directly in front of the pupil Asks the client to fix the gaze upon an object and look straight ahead
