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?

A. Increased lacrimation may cause discomfort but does not directly contribute to a risk of injury. B. Miotics constrict the pupil, leading to decreased night vision, which increases the client's risk for injury, particularly in low-light conditions. C. Sensitivity to light (photophobia) may cause discomfort but is less likely to contribute directly to injury. D. Diminished color perception can occur but does not typically pose a significant risk for injury compared to decreased night vision.
