Chapter 42 : Caring for Clients With Eye Disorders Questions
Question 1 of 5
Following an ophthalmologic exam, an anxious client asks the nurse, 'How serious is a refraction error?' Which is the best response from the nurse?
Correct Answer: B
Rationale: Refractive errors can be corrected with glasses or contact lenses. Telling a client that 'nothing is serious' does not provide the necessary information to help alleviate fears. The word surgery can increase fears. If the refractive error is associated with aging, this is a normal finding but does not provide information about the condition.
Question 2 of 5
A middle-aged client reports increasing difficulty reading newspaper print. Which of the following nursing explanations best describes this type of refractive error?
Correct Answer: C
Rationale: Presbyopia is a result of poor accommodation due to a loss of elasticity of the ciliary muscles and lens. Nearsighted refers to myopia. Cloudiness of lens is also associated with the aging process and does interfere with vision as a result of cataract formation. Floaters in the eyes are more apparent with aging but appear as dark spots.
Question 3 of 5
At morning report, the nurse learns the assigned client is blind. Which question should the nurse ask the client upon initial assessment?
Correct Answer: D
Rationale: Many people who are considered blind perceive light and motion. Establishing this fact can help in developing a plan of care for this client. Establishing cause and length of time for visual impairment is not required for initial care. Asking the client about dependence is important, but the new environment could provide safety issues (even if independent) if no perception of light is identified.
Question 4 of 5
Which technique would be most beneficial for ambulation of a client who is visually impaired?
Correct Answer: C
Rationale: A blind person feels more secure and safe when assisted by someone who is sighted. The nurse should walk slightly ahead while allowing the client to hold onto the nurse's upper arm or elbow. Speaking before touching is an important care action in dealing with clients who have impaired vision but does not assist in ambulation. Providing a detailed description of the room may allow the client an image of the surroundings but is not as helpful in initial ambulation. Finding a perfect fit between guide dog and client is a lengthy process and should be pursued upon request of client.
Question 5 of 5
While cleaning gutters, a client reports getting debris in the eyes. On inspection, the nurse notes no obvious foreign object. Which diagnostic evaluation technique would be most beneficial for this client?
Correct Answer: A
Rationale: Fluorescein dye stains the eye and helps to identify minute foreign body or abrasions in the cornea. X-ray of the eye orbit would be done if a blow to the area preceded the visit. Assessment of intraocular movements (cranial nerves III, IV, and VI) would not be indicated.
Tonometry is done for assessment of intraocular pressure and would not be indicated.
