Question 1

A client comes to the eye clinic for a routine check-up. The client tells the nurse they think they are color blind. What screening test does the nurse know will be performed on this client to assess for color-blindness?
A) Rosenbaum
B) Jaeger
C) Ishihara
D) Snellen

Accepted Answer

The Ishihara test is a common screening test used to assess for color-blindness. The test uses a series of plates with different colored dots arranged in specific patterns. People with color-blindness have difficulty seeing certain combinations of colors and will not be able to see the pattern. The Rosenbaum test assesses near vision acuity, the Jaeger test assesses reading ability, and the Snellen test assesses distance visual acuity.

Question 2

When gathering an ocular history on a male client aged 42, what would be an important for the nurse to ask?
A) Have you ever failed an eye exam?
B) Have you ever failed an Ishihara?
C) Would you rather have a Rosenbaum or a Jaeger?
D) When was your last eye exam?

Accepted Answer

Knowing when the client's last eye exam was can give important information about their eye health history and any potential changes or concerns since their last exam. The other choices (A, B, and C) may also be relevant to know, but are not as important as knowing when the client last had a comprehensive eye exam.

Question 3

Which of the following nursing intervention should be included during the assessment of a client with an eye disorder?
A) Check the extraocular muscles by instructing the client to keep his or her head still when following an object.
B) Examine the retina with a direct ophthalmoscope.
C) Use a tonometer to indent or flatten the surface of the eye.
D) Instruct the client to stare at the central fixation spot on an Amsler grid and report if he or she sees any distortion of the squares.

Accepted Answer

Checking the extraocular muscles by instructing the client to keep their head still while following an object is a standard assessment to evaluate the function of the eye muscles and cranial nerves associated with eye movement.

Question 4

A client presents at the clinic complaining of a loss of balance. What test should the nurse expect the physician to carry out on a client with a loss of balance?
A) Audiometric test
B) Romberg test
C) Weber test
D) Rinne test

Accepted Answer

The Romberg test is used to assess a client's balance. The client stands with feet together and eyes closed for 30 seconds while the physician observes for balance issues. The other tests listed are used to assess hearing.

Question 5

The nursing student hopefuls are taking a pre-nursing anatomy and physiology class. What will they learn is the anatomical feature that equalizes air pressure in the middle ear?
A) Eustachian tube
B) The malleus
C) The pinna
D) The meatus

Accepted Answer

The Eustachian tube connects the middle ear to the back of the throat and equalizes air pressure in the middle ear. The malleus is a bone in the middle ear, the pinna is the visible part of the outer ear, and the meatus is the opening into the ear canal.

Question 6

A client, diagnosed with a cataract, comes into the clinic. What assessments should the nurse observe in this client?
A) A burning sensation and the sensation of an object in the eye
B) Blurred or cloudy visual image
C) Inability to produce sufficient tears
D) A swollen lacrimal caruncle

Accepted Answer

The nurse should observe the client for blurred or cloudy visual images, which is a common symptom of cataracts. Option A is commonly seen in conjunctivitis or stye infections. Option C is a symptom of dry eye syndrome. Option D is seen in cases of inflamed eyelids or eyelid infections.

Question 7

You are doing hearing tests at the local junior high school. Which child has normal hearing acuity?
A) A client who first perceives sound at 20 dB
B) A client who first perceives sound at 40 dB
C) A client for whom the painful sound occurs at 80 dB
D) A client for whom the painful sound occurs at 100 dB

Accepted Answer

Normal hearing acuity is defined as the ability to perceive sounds at or below 20 dB. Therefore, a client who first perceives sound at 20 dB has normal hearing.

Question 8

The nurse is giving a visual field examination to a 55-year-old male client. The client asks what this test is for. What would be the nurse's best answer?
A) "This test measures visual acuity."
B) "This test measures how well your eyes move."
C) "This test is to see how well your eyes are aging."
D) "This test measures peripheral vision and detects gaps in the visual field."

Accepted Answer

The visual field examination measures peripheral vision and detects gaps or deficits in the visual field. This test helps identify conditions such as glaucoma, retinal detachment, and other visual abnormalities.

Question 9

The nurse is preparing a client for electronystagmography. The nurse knows that this test is done in conjunction with what?
A) Audioscope exam
B) Caloric stimulation
C) Hearing screening
D) Audiometry

Accepted Answer

Electronystagmography (ENG) is done in conjunction with caloric stimulation, which involves irrigating the ear with either warm or cool water to assess the vestibular system's response. This helps diagnose the cause of vertigo or balance problems. Audioscope exam, hearing screening, and audiometry focus on assessing hearing loss and are not directly related to ENG.

Question 10

Audiometry is testing that measures hearing acuity precisely. Who does the nurse know can perform audiometric testing?
A) School nurse
B) Hearing aide salesperson
C) Audiologist
D) Nursing assistant

Accepted Answer

Only an audiologist is trained and qualified to perform audiometric testing. School nurses and nursing assistants may screen for hearing issues, but they cannot perform diagnostic testing. Hearing aid salespersons are not medical professionals and should not be relied upon for accurate testing.

Question 11

A client is having problems with dizziness and complains of the "room spinning". The physician performs the caloric stimulation test. The nurse knows that a diminished response in one eye during the caloric stimulation testis indicative of what?
A) Inner ear disorder
B) Middle ear disorder
C) Outer ear disorder
D) Age-related macular degeneration

Accepted Answer

A diminished response in one eye during the caloric stimulation test is indicative of an inner ear disorder. The test involves irrigating the ear canal with warm or cool water to stimulate the vestibular system and assess for any abnormalities in balance and coordination. A distorted response may indicate a dysfunction in the inner ear.

Question 12

The client is having a Weber test. During a Weber test, where should the tuning fork be placed?
A) On the mastoid process behind the ear
B) In the midline of the client's skull or in the center of the forehead
C) Near the external meatus of each ear
D) Under the bridge of the nose

Accepted Answer

During a Weber test, the tuning fork should be placed in the midline of the client's skull or in the center of the forehead. This test is done to assess for hearing loss and lateralization of sound. Placing the tuning fork on the mastoid process behind the ear (choice A) is part of the Rinne test, which is performed to compare air conduction to bone conduction. Placing the tuning fork near the external meatus of each ear (choice C) is also part of the Rinne test. Placing the tuning fork under the bridge of the nose (choice D) is not part of any hearing tests.

Question 13

You are the clinic nurse in an ophthalmic clinic. When assessing clients, what client has an abnormal intraocular pressure (IOP)?
A) A client with an IOP of 8 mm Hg
B) A client with an IOP of 15 mm Hg
C) A client with an IOP of 19 mm Hg
D) A client with an IOP of 21 mm Hg

Accepted Answer

Normal intraocular pressure ranges from 10 to 21 mm Hg. An IOP of 8 mm Hg is below the normal range and is considered abnormal.

Question 14

What is located in the cochlea of the inner ear?
A) Semicircular canals
B) Labyrinth
C) Vestibulocochlear nerve
D) Organ of Corti

Accepted Answer

The cochlea of the inner ear contains the Organ of Corti, which detects sound vibrations and sends signals to the brain. The semicircular canals and labyrinth are both part of the vestibular system, which is responsible for balance and spatial orientation. The vestibulocochlear nerve is the eighth cranial nerve that carries both auditory and vestibular information from the inner ear to the brain.

Question 15

A client comes to the occupational health nurse complaining of eye irritation. The client works in a dusty, outdoor environment. Why should the nurse advise periodic blinking to this client?
A) To control the amount of sunlight that enters the eye
B) To minimize the impact of the wind on the eye and to trap foreign debris
C) To clear the dust and particles from the surface of the eyes
D) To prevent the collection of tears over the surface of the eye

Accepted Answer

Blinking helps to clear the dust and particles from the surface of the eyes by spreading tears evenly across the eye, which washes away foreign materials.

Question 16

A client has been referred to an ophthalmologist for suspected macular degeneration. The nurse knows to prepare what test for the physician to give the client?
A) Ishihara polychromatic plates
B) Visual field
C) Amsler grid
D) Slit lamp

Accepted Answer

The Amsler grid is a test specifically used to assess the central visual field and is commonly administered to patients suspected of having macular degeneration. The Ishihara polychromatic plates test color vision, the visual field test evaluates the range and sensitivity of peripheral vision, and the slit lamp is a tool used by ophthalmologists to examine the anterior and posterior segments of the eye.

Question 17

A client is scheduled to have a cataract removed and an artificial lens implanted. What test would the nurse know would be useful in measuring for an intraocular lens implant in this client?
A) Slit lamp
B) Retinal angiography
C) Visual field
D) Ultrasonography

Accepted Answer

Ultrasonography is used to measure the length and shape of the eye to determine the appropriate power and size of the intraocular lens implant. Slit lamp, retinal angiography, and visual field tests do not provide this information.

Question 18

A client comes to the walk-in clinic complaining of an earache. The cause is found to be impacted cerumen. The client asks the nurse what they can do at home to soften hardened cerumen. What should the nurse recommend to a client to soften hardened cerumen?
A) Avoid harsh sunlight.
B) Increase intake of red meat.
C) Increase intake of beta-carotene.
D) Take nonprescription preparations.

Accepted Answer

Taking nonprescription preparations, such as mineral oil or hydrogen peroxide, can help soften impacted cerumen and make it easier to remove. However, it is important to follow manufacturer instructions and consult a healthcare provider before using any ear drops or other preparations. Avoiding harsh sunlight and increasing intake of beta-carotene or red meat will not soften impacted cerumen.

Question 19

An aging client is brought to the eye clinic by the son. The son states he has seen his parent holding reading materials at an increasing distance to focus properly. What age-related changes does this indicate?
A) Cataract
B) Presbyopia
C) Myopia
D) Macular degeneration

Accepted Answer

The aging client is experiencing presbyopia, or the age-related loss of the eyes' ability to focus on near objects. This is characterized by the need to hold reading materials farther away to focus properly. Cataracts and macular degeneration are also age-related changes in the eyes, but do not specifically cause difficulty with near vision. Myopia, or nearsightedness, is not an age-related change and typically develops earlier in life.

Question 20

While assessing a client's ocular history, what would be an important to ask the client?
A) Are you having your eyes dilated?
B) Do you know what peripheral vision means?
C) Are you having any current problems seeing?
D) Do you know what a Snellen chart is?

Accepted Answer

Asking about current problems with vision is important in assessing the client's ocular history as it can provide insight into any current conditions or concerns with the client's eyesight.
