Question 1 of 5
Audiometry is testing that measures hearing acuity precisely. Who does the nurse know can perform audiometric testing?
Correct Answer: C
Rationale: Audiometry is done by an audiologist. Audiometric testing measures hearing acuity precisely. The other options can screen hearing, but they cannot do audiometric testing.
Question 2 of 5
The nurse is instructing a nursing student when a new client comes to the eye clinic. The client reports suspecting a corneal abrasion. The nurse should explain what to the student nurse?
Correct Answer: C
Rationale: A slit lamp is a binocular microscope that magnifies the surface of the eye. A beam of light, narrowed to a slit, is directed at the cornea, facilitating an examination of structures and fluid in the anterior segment of the eye. This examination is used to identify disorders such as corneal abrasions, iritis, conjunctivitis, and cataracts. The other options are not used to detect corneal abrasions.
Question 3 of 5
The nurse is assessing a client's eyes as part of the inspection part of the assessment process. For which reason does the nurse identify a normal variation in the angle of the lateral and medial canthus?
Correct Answer: A
Rationale: The line between the lateral and medial canthus is usually horizontal. Variations are noted abnormally in children with Down syndrome and normally in individuals of Asian descent. Structural changes and cosmetic variations are not considered normal changes noted on assessment.
Question 4 of 5
The nurse is assisting in providing coordination of services between the physician's office and vision specialist's office for a client who is being referred for potential retinal surgery. Which eye care specialist will the nurse make the referral to?
Correct Answer: C
Rationale: The ophthalmologist is a physician who performs surgery on clients with eye disorders. The optician makes eyeglasses or contact lenses. The optometrist tests vision and prescribes corrective lenses. The ophthalmic technician assists in selective eye tests and procedures.
Question 5 of 5
The nurse is obtaining a history on a client stating the inability to read the newspaper and seeing detail when looking at an image. Which assessment test would add additional data for a diagnosis?
Correct Answer: C
Rationale: The client states symptoms of the inability to discriminate letters, words, and details of an image, indicating the degeneration of the macula. If the macula is damaged, the client will only have the ability to see movement and gross objects in the peripheral fields. Assessing the peripheral vision will add essential information. The other visual tests are not as important at this time.
