After checking a client's pupillary response to light, the practical nurse (PN) tells the registered nurse (RN) that the client's pupils are constricted with minimal response to light. Before verifying the PN's findings, which action should the RN take?

A. Review the client's medication list: Certain medications such as opioids, cholinergics, or miotic eye drops can cause pupillary constriction and sluggish reactivity. Reviewing the client’s medication profile can help determine if the abnormal pupillary response is pharmacologically induced or a sign of a neurological problem.B. Assess the client's visual fields: Visual field testing evaluates peripheral vision and is not directly related to assessing pupillary response. This would not provide immediate insight into the cause of constricted pupils and is not the priority action in this situation.C. Brighten the light in the client's room: While lighting can affect pupil size during assessment, constricted pupils with minimal response typically indicate an internal cause rather than poor lighting. Brightening the room may not significantly alter findings or explain the abnormal response.D. Administer PRN saline eye solution: Saline eye drops may relieve dryness or irritation but have no effect on pupil size or reactivity. Administering them does not address the root cause of constricted pupils and could delay proper assessment and treatment.
