Jenny with an advanced breast cancer is prescribed Nolvadex (tamoxifen). When teaching the client about this drug, the nurse should emphasize the importance of reporting which adverse reaction immediately?
A. Anorexia
B. Headache
C. Hearing loss
D. Vision changes
Correct Answer: D. Vision changes
Option D: Tamoxifen, a selective estrogen receptor modulator (SERM) causes ocular side effects such as dryness, irritation, and cataracts. The client must report changes in visual acuity immediately because this adverse effect may be irreversible.
Options A and B: Although the drug may cause anorexia, headache, and hot flashes, the client need not report these adverse effects immediately because they don’t warrant a change in therapy.
Option C: Tamoxifen isn’t associated with hearing loss.
