Objective: 1
Page and Header: 1759, Assessment of the Eye

Feedback: The nurse should provide adequate lighting in the patient’s room, as the rods are mainly responsible for night vision or vision in low light. If the patient’s rods are impaired, the patient will have difficulty seeing in dim light. The cones in the eyes provide best vision for bright light, color vision, and fine detail.

3. A patient has come to the office for her first eye examination. The patient is diagnosed as having a visual acuity of 20/40. The patient asks the nurse what these numbers mean. What is a correct response by the nurse?
A) “A person whose vision is 20/40 can see an object from 40 feet away that a person with 20/20 vision can see from 20 feet away.”

B) “A person whose vision is 20/40 can see an object from 20 feet away that a person with 20/20 vision can see from 40 feet away.”
C) “A person whose vision is 20/40 can see an object from 40 inches away that a person with 20/20 vision can see from 20 inches away.”

D) “A person whose vision is 20/40 can see an object from 20 inches away that a person with 20/20 vision can see from 40 inches away.”

Ans: B Chapter: 58

Client Needs: B
Cognitive Level: Comprehension Difficulty: Moderate
Integrated Process: Nursing Process Objective: 2
Page and Header: 1760, Assessment

Feedback: The Snellen chart is a tool used to measure visual acuity. It is composed of a series of progressively smaller rows of letters and is used to test distance vision. The fraction 20/20 is considered the standard of normal vision. Most people can see the letters on the line designated as 20/20 from a distance of 20 feet. A person whose vision is 20/40 can see an object from 20 feet away that a person with 20/20 vision can see from 40 feet away. This makes options A, C, and D incorrect.

4. You are preparing to discharge a patient home. During your discharge teaching you realize that the patient is not able to read the medication bottles and has not been taking her medications at home. How would you intervene appropriately in this situation?
A) By asking the social worker to investigate nursing home placement
B) By asking the social worker to investigate community support agencies
C) By informing that patient that surgery will correct the vision problem
D) By informing the patient that she will need to go to a rehabilitation facility for vision training

Ans: B
Chapter: 58
Client Needs: B
Cognitive Level: Application
Difficulty: Moderate
Integrated Process: Teaching/Learning
Objective: 6
Page and Header: 1765, Low Vision and Blindness

Feedback: Managing low vision involves magnification and image enhancement through the use of low-vision aids and strategies and referrals to social services and community agencies serving those with visual impairment. Community agencies, such as the Lighthouse National Center for Vision and Aging, offer services to low-vision patients that include training in independent living skills and a variety of assistive devices for vision enhancement, orientation, and mobility, preventing patients from needing to enter a nursing facility. A rehabilitation facility is generally not needed by the patients to learn to use the assistive devices or gain a greater degree of independence. Surgery is also generally not a necessary component to independent living for this group of patients.

5. The nurse is performing patient teaching with a patient newly diagnosed with glaucoma. The nurse teaches the patient that this disease has a familial tendency. How often would the nurse tell the patient that family members should undergo examination for the detection of glaucoma?
A) At least monthly

B) At least once every 2 years C) At least once every 5 years D) At least once every 10 years

Ans: B
Chapter: 58
Client Needs: B
Cognitive Level: Comprehension Difficulty: Moderate
Integrated Process: Teaching/Learning Objective: 3
Page and Header: 1772, Glaucoma

Feedback: Glaucoma has a family tendency and family members should be encouraged to undergo examinations at least once every 2 years to detect glaucoma early. Testing on a monthly basis is not necessary and excessive. This makes options A, C, and D incorrect.
