Question 1

A client tells the nurse they are experiencing blurred vision. Which initial question should the nurse ask the client?

Accepted Answer

Asking the client to describe their vision is the most open-ended question that allows for a comprehensive understanding of the client's experience, which is essential for initial assessment.

Question 2

The nurse is assessing the client's vision. Which information should the nurse provide the client?

Accepted Answer

The standard distance for a Snellen chart vision test is 20 feet, which allows for accurate assessment of visual acuity.

Question 3

The nurse is preparing to perform the cover and uncover test on a client. Which explanation will the nurse provide the client prior to performing the exam?

Accepted Answer

The cover and uncover test is used to assess for strabismus and the balance mechanism that keeps the eyes aligned and parallel.

Question 4

During an eye examination, the nurse requests that the client read letters located on the Snellen E chart. The client's vision is determined to be 20/200. Which statements regarding this client's vision are accurate? Select all that apply.

Accepted Answer

- A) A person with 20/200 vision is considered legally blind in the United States, as they can only see at 20 feet what a person with normal vision can see at 200 feet.- D) Myopia, or nearsightedness, means difficulty seeing distant objects clearly, which is consistent with a 20/200 vision assessment.

Question 5

The nurse is assessing a client's visual fields by confrontation. Which actions by the nurse indicate appropriate practice? Select all that apply.

Accepted Answer

The answer of The nurse is assessing a client's visual...

Question 6

The nurse is preparing to review the secondary sources of data for a patient with glaucoma. Which diagnostic testing should the nurse anticipate to be included?

Accepted Answer

Tonometry is a diagnostic test used to measure intraocular pressure, which is crucial in diagnosing and managing glaucoma.

Question 7

The nurse is reviewing the records of a client with astigmatism. Which visual changes should the nurse anticipate?

Accepted Answer

Astigmatism is a common vision condition caused by an irregularly shaped cornea or lens that leads to distorted or blurred vision. Double vision (diplopia) can be a symptom of astigmatism when the irregular shape of the cornea or lens causes light rays to split and create multiple images on the retina.

Question 8

A client asks the nurse what is the name of the structure of the eye that is colored.

Accepted Answer

The iris is the colored part of the eye that controls the size of the pupil and the amount of light that enters the eye.

Question 9

During an eye assessment, a young adult client reports difficulty seeing items within close range. This assessment data is consistent with which factor?

Accepted Answer

Hyperopia, or farsightedness, is a condition where distant objects can be seen more clearly than close ones, which aligns with the client's difficulty seeing items within close range.

Question 10

The nurse taught the client how to self-administer eye drops. During the return demonstration, the client inadvertently touched the applicator to their cornea, which caused the client to blink and produce tears. Which term should the nurse describe the reflex elicited by the client?

Accepted Answer

Touching the cornea stimulates the corneal reflex, causing blinking and tear production as a protective mechanism. This is a normal physiological response to protect the eye from potential harm.

Question 11

The nurse is assessing the eyes of an older adult client. Which finding is expected by the nurse based on the client's age?

Accepted Answer

Presbyopia, the difficulty in reading or seeing at close range, is a common age-related change in the eye's ability to focus, often noticeable in adults over the age of 40.

Question 12

A client tells the nurse they experience double vision. Which question should the nurse ask the client?

Accepted Answer

Double vision can be a side effect of certain medications, so it's important to ask about medication use.

Question 13

A client asks the nurse why it is important to protect their eyes from the sun. Which response should the nurse provide to the client?

Accepted Answer

Excessive sun exposure is a known risk factor for the development of cataracts, which is the clouding of the lens in the eye that affects vision.

Question 14

The nurse reviewing the records of a client notes there is a diagnosis of nystagmus. Which should the nurse recognize is a causative factor of the condition?

Accepted Answer

Nystagmus is characterized by involuntary, rapid movements of the eyes, which can be caused by weakness or abnormalities in the extraocular muscles controlling eye movement, among other neurological reasons. Eye infections, cataracts, and issues with lens accommodation are not direct causes of nystagmus.

Question 15

The nurse is assessing the fundus of the older adult client's eye with an ophthalmoscope. The nurse determines that there is a cyst within the macula. Which client symptom does the nurse anticipate?

Accepted Answer

The macula is responsible for central vision. A cyst in the macula would likely impair central vision, not peripheral vision, glucose levels, or blood pressure.

Question 16

The nurse notes that a client is unable to control the amount of light that enters the eye. Which structure's dysfunction is the most likely cause of this problem?

Accepted Answer

The iris is the part of the eye responsible for controlling the amount of light that enters the eye by adjusting the size of the pupil. Dysfunction of the iris would lead to an inability to properly regulate light intake.

Question 17

The nurse is performing a visual examination on a client with complaints of black dots appearing in the visual field. Which statement by the nurse is most appropriate in this situation?

Accepted Answer

Floaters are small, dark shapes that float across your vision, often described as black dots, and are usually normal. They are caused by small pieces of debris that float in the vitreous humor of the eye. While they can be annoying, they typically don't indicate a serious problem.

Question 18

The nurse has elicited a blink reflex in a client. Which structure of the eye is responsible for the reflex?

Accepted Answer

The blink reflex is primarily triggered by stimulation of the cornea, which is the clear, protective outer layer of the eye. This reflex helps protect the eye from foreign objects and helps to keep it moist.

Question 19

A client tells the nurse they see halos around light. Which question should the nurse ask the client?

Accepted Answer

Halos around lights can be a side effect of certain medications, such as those used to treat glaucoma. Asking about routine medications can help identify if this is a potential cause.

Question 20

The nurse is preparing to visually inspect a client's eye. Which should the nurse anticipate to note? Select all that apply.

Accepted Answer

The answer of The nurse is preparing to visually inspect...
