Upon reading a patient's history, the nurse learns that the patient has a condition that has affected the rods in his eyes. Considering this information, the nurse will:
A) Provide adequate lighting in the patient's room to help him achieve his best vision
B) Provide a dimly lit room to assist the patient in achieving his best vision
C) Carefully point out color differences for the patient
D) Carefully point out fine details for the patient
Ans: A
Feedback: The nurse should provide adequate lighting in the patient's room, as the rods are mainly responsible for night vision or vision in low light. If the patient's 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.
