A client is receiving miotics for the treatment of open-angle glaucoma. The nurse determines that a priority nursing problem is, "Risk for injury." This nursing problem is based on which etiology?

Rationale: A. Increased frequency of lacrimation: Excessive tearing can cause discomfort and blurred vision, but it does not significantly increase the client’s overall risk for injury. The impact is usually temporary and less concerning than impaired vision in low-light conditions. B. Diminished color perception: Changes in color vision may interfere with certain activities, but they are less likely to create dangerous situations compared with visual difficulties that occur at night, when the environment is darker and navigation is more challenging. C. Increased sensitivity to light: Photophobia may cause discomfort in bright environments, but it does not typically pose as high a risk for injury as difficulty seeing in dim or dark settings, where falls and accidents are more likely to occur. D. Decreased night vision: Miotics constrict the pupil, reducing the amount of light entering the eye and impairing night vision. This creates a significant risk for falls, accidents, or injuries in poorly lit environments, making it the priority etiology for the nursing problem.
