Answer to Question 1

ANS: A
The nurse should devise a plan of care that is accommodating of the patient's visual deficit. Placing a sticker on the call light allows the patient to page the nurse for assistance as needed. Using family members is not the best option. Making hourly rounds is not sufficient; the nurse needs to ensure that the patient can get in touch at any time. Color coding the call light will not help a severely visually impaired patient.

Answer to Question 2

ANS: C
Light rays enter the convex cornea and begin to converge. An adjustment of light rays occurs as they pass through the pupil and lens. Change in the shape of the lens focuses light on the retina. The sensory retina contains the rods and cones (i.e., photoreceptor cells sensitive to stimulation from light). Photoreceptor cells send electrical potentials by way of the optic nerve to the brain.
