A client with advanced breast cancer is prescribed tamoxifen (Nolvadex). When teaching the client about this drug, the nurse should emphasize the importance of reporting which adverse reaction immediately?
Correct Answer: A
Rationale: Tamoxifen (Nolvadex) is associated with the potential side effect of retinopathy, which can present as changes in vision. Retinopathy is a serious condition that can lead to vision loss. Therefore, it is crucial for the client to report any vision changes immediately to their healthcare provider for further evaluation and management. Reporting this adverse reaction promptly can help prevent serious complications and ensure the client's safety and well-being.
