Chapter 46 : Assessment of the Eye and Vision Questions
Question 1 of 5
The nurse is administering eyedrops to a client with an infection in the right eye. The drops go in both eyes, and two different bottles are used to administer the drops. The nurse accidentally uses the left eye bottle for the right eye. What action by the nurse is best?
Correct Answer: B
Rationale: The nurse has contaminated the clean bottle by using it on the infected eye. The nurse needs to obtain a new bottle of solution to use on the left eye. The other actions are not appropriate.
Question 2 of 5
The nurse enters an examination room to help with an eye examination. The client is directed toward the assessment chart shown below. What is the provider assessing?
Correct Answer: A
Rationale: This is an Ishihara chart, which is used for assessing color vision. Depth and spatial perception are not typically assessed in a routine vision assessment. Visual acuity is usually tested with a Snellen chart.
Question 3 of 5
The student learning about vision should remember which facts related to the eyes? (Select all that apply.)
Correct Answer: A,C,D,E
Rationale: The inflow and outflow of aqueous humor controls the intraocular pressure. Glaucoma results when the pressure is dramatically high. Muscles of the iris control the amount of light entering the eye. Rods work in low light conditions. Cones work in bright light conditions.
Question 4 of 5
The nursing student studying the eye learns that which cranial nerves control its functions? (Select all that apply.)
Correct Answer: A,B,C,D,E,F
Rationale: The cranial nerves involved with eye function include II, III, IV, V, VI, and VII. Cranial nerve X is not involved.
Question 5 of 5
The nursing student learns that age-related changes affect the eyes and vision. Which changes does this include? (Select all that apply.)
Correct Answer: A,B,C,D
Rationale: Normal age-related changes include decreased eye muscle tone, development of arcus senilis, decreased color perception, and increased far point of near vision (presbyopia). The near point of vision typically decreases with age.
