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

Choice A reason: Decreased night vision is a significant concern for clients receiving miotics for open-angle glaucoma. Miotics, such as pilocarpine, work by constricting the pupil (miosis), which can reduce the amount of light entering the eye. This effect is particularly problematic in low-light conditions, leading to decreased night vision and increasing the risk of injury due to poor visibility Choice B reason: Increased sensitivity to light, also known as photophobia, can occur with the use of miotics, but it is not the primary concern related to the risk of injury. While photophobia can cause discomfort and avoidance of bright environments, it does not directly contribute to the risk of injury as significantly as decreased night vision. Choice C reason: Increased frequency of lacrimation (tearing) can be a side effect of miotics, but it is not a major factor in the risk of injury. Excessive tearing can cause discomfort and blurred vision temporarily, but it does not pose a significant risk for injury compared to decreased night vision. Choice D reason: Diminished color perception is not a common side effect of miotics. Miotics primarily affect the pupil size and accommodation, rather than color vision. Therefore, this choice is not relevant to the risk of injury associated with the use of miotics.
