The nurse has taken shift report on her patients and has been told that one patient has an ocular condition that has primarily affected the rods in his eyes. Considering this information, what should the nurse do while caring for the patient?

Answer Explanation: The nurse should provide adequate lighting in the patients room, as the rods are mainly responsible for night vision or vision in low light. If the patients rods are impaired, the patient will have difficulty seeing in dim light. The cones in the eyes provide best vision for bright light, color vision, and fine detail.
