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

A) Increased frequency of lacrimation is not typically associated with miotic therapy. Miotics work by constricting the pupil and increasing outflow of aqueous humor to reduce intraocular pressure, but they do not directly affect lacrimation (tear production). Therefore, this option is not the etiology for the “Risk for injury” nursing problem. B) Decreased night vision is a common side effect of miotic therapy. Miotics constrict the pupil, which can reduce the amount of light entering the eye, leading to impaired night vision or difficulty seeing in low-light conditions. This impaired vision increases the risk of injury, particularly in situations with reduced lighting. C) Increased sensitivity to light (photophobia) is not typically associated with miotic therapy. Miotics constrict the pupil, which may actually reduce sensitivity to light by decreasing the amount of light entering the eye. Therefore, increased sensitivity to light is not the etiology for the “Risk for injury” nursing problem in this case. D) Diminished color perception is not a common side effect of miotic therapy. Miotics primarily affect pupil constriction and intraocular pressure but do not typically alter color perception. Therefore, diminished color perception is not the etiology for the “Risk for injury” nursing problem.
