Final answer:
The nurse interprets that the client with glaucoma has misconceptions about glaucoma effects and needs information, as glaucoma typically causes loss of peripheral vision, not an improvement in any aspect of vision.
Step-by-step explanation:
The nurse would interpret that the client diagnosed with glaucoma needs information about the expected effects of this condition when she incorrectly states that her peripheral vision might improve. In fact, glaucoma typically leads to the loss of peripheral vision, and patients may experience 'tunnel vision,' which means that only the central visual field will be perceived. This condition does not lead to improved central vision, enhanced night vision, or improved color vision; rather, it typically causes a gradual decrease in peripheral vision, which can progress to a loss in central vision if left untreated.
