The nurse is assessing a client for the possibility of a lens opacity. Which assessment finding confirms this problem?
a. Increased intraocular pressure
b. Absence of a red reflex
c. Decreased central vision
d. Positive corneal staining
B
The red reflex is elicited with an ophthalmoscope and represents reflection of the ophthalmos-copic light through the lens onto the vascular retina. The absence of a red reflex strongly indi-cates a lens opacity that does not allow light to penetrate through to the retina. The other answers are not related to a lens opacity. Increased intraocular pressure is measured by tonometry and could indicate glaucoma. Decreased central vision is measured by a Snellen chart and a Jaeger card and indicates decreased visual acuity. Positive corneal staining with topical dye could indi-cate corneal abrasion.
