The nurse is performing a focused interview and eye assessment on a client. Which assessment findings indicate the client is experiencing a vision problem? (Select all that apply)
A.
As the nurse dims the lights in the room, the client’s pupils dilate.
B.
As the nurse checks for accommodation, the pupils remain dilated.
C.
The clients far vision acuity is 20/20 bilaterally.
D.
The client exhibits a symmetrical pupillary light reflex response.
The correct answer and Explanation is :
In a focused eye assessment, the following findings would indicate the client is experiencing a vision problem:
B. As the nurse checks for accommodation, the pupils remain dilated.
Explanation:
- Accommodation Response: Accommodation is the eye’s ability to focus on near objects by changing the shape of the lens. When a person shifts their gaze from a distant object to a near one, the pupils should constrict to increase the depth of field and provide a clearer image. If the pupils remain dilated during this process, it indicates a problem with accommodation, which could be due to issues such as paralysis of the ciliary muscle, which affects the lens’s ability to focus properly.
- Pupillary Light Reflex: The pupillary light reflex is the constriction of the pupils in response to light. If the pupils constrict symmetrically when a light is shone in the eyes, this indicates that the reflex pathways are functioning properly. If the reflex is not symmetrical or not present, it suggests a problem with the neural pathways or the muscles controlling pupil size.
- Pupils Dilating in Dim Light: Pupils dilating in dim light is a normal response. This adjustment, known as pupillary dilation, allows more light to enter the eye in low-light conditions to improve vision. However, this response alone does not indicate a vision problem.
- Visual Acuity: A visual acuity of 20/20 bilaterally is considered normal vision. This means the client can see clearly at a distance of 20 feet what should be seen at that distance. This finding does not indicate a vision problem.
In summary, the primary indicator of a vision problem in this context is the pupils remaining dilated when checking for accommodation. This suggests a potential issue with the eye’s focusing ability.
