| 1. | 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 | |
| Ans: | C | |
| Feedback: | ||
| Periodic blinking clears the dust and particles from the surface of the eyes. The eyelids also spread tears over the surface of the eye, which helps bathe and lubricate the surface. The eyelids protect against foreign bodies and adjust the amount of light that enters the eye, whereas the eyelashes trap foreign debris. | ||
| 2. | A client, diagnosed with a cataract, comes into the clinic. What assessment 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 | |
| Ans: | B | |
| Feedback: | ||
| When a cataract forms, the light is blocked from reaching the macula, and the visual image becomes blurred or cloudy. The client does not experience any burning or the sensation of an object in the eye, an inability to produce sufficient tears, or a swollen lacrimal caruncle. | ||
| 3. | 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 | |
| Ans: | B | |
| Feedback: | ||
| The Weber test is performed by striking the tuning fork and placing its stem in the midline of the client’s skull or in the center of the forehead. In the Rinne test, the tuning fork is struck and placed on the mastoid process behind the ear. The tuning fork is not placed near the external meatus of each ear or under the bridge of the nose. | ||
| 4. | You are doing hearing tests at the local junior high school. Which of the following indicates normal hearing in a child? | |
| 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 | |
| Ans: | A | |
| Feedback: | ||
| The lowest level of sound that normal persons may first perceive is 20 dB. The painful sounds occur at 120 dB. The hearing acuity is determined by measuring the intensity at which a person first perceives sound. | ||
| 5. | 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 | |
| Ans: | A | |
| Feedback: | ||
| During the caloric stimulation test, a diminished response in one eye is significant for an inner ear disorder such as Ménière’s disease. It does not signify a middle ear disorder, an outer ear disorder, or age-related macular degeneration. | ||
