Chapter 11: Vision Touhy: Ebersole & Hess' Toward Healthy Aging, 9th Edition MULTIPLE CHOICE 1. You have four rooms to choose from for your older client to be admitted this afternoon.
Which room would you choose? a. A brightly lit, blue room with cozy throw rugs b. An orange-carpeted room with soft lighting and yellow walls c. A brightly lit, blue room with an EZ-Glide wax floor d. A fluorescent-lighted room with green walls and a glossy, tiled floor ANS: B
Light colors such as red, orange, and yellow are more easily seen by aging eyes. Softer lighting will help reduce some of the glare and is also easier seen by aging eyes. Fidelity of color is less accurate with the blues, greens, and violets of the spectrum, and the slowed ability of the pupils to adjust to light makes glare a problem. Glare can come from sunlight, but a brightly waxed floor and glossy tile can also cause glare.

An older adult client shares with the nurse that, “I don’t know what it is but it seems that I
need more light for reading or even watching television as I get older.” The nurse explains that aging may cause this change due to the: a. slower ability of the pupil to adjust to changes in lighting. b. impact arcus senilis has on visual acuity c. flattening and thinning of the cornea. d. retinal changes that begin to occur with aging. ANS: A
A slowed ability of the pupil to accommodate to changes in light accounts for the need of this patient to have more light in order to read. Arcus senilis does not affect vision. It is true that the cornea becomes flatter and thinner with aging, which results in astigmatism. Astigmatism does not account for the need for increased light that this patient is reporting. The changes in the retina do not account for the need for increased light that this patient is reporting.

A 77-year-old client being treated for glaucoma asks the nurse what causes glaucoma. The
nurse’s response is: a. the exact etiology of glaucoma is variable and often unknown. b. spasms of the orbicular muscle. c. changes to the suspensory ligaments, ciliary muscles, and parasympathetic nerves. d. bits of broken coalesced vitreous from the peripheral or central part of the retina.
