What finding should a nurse report as a priority for a client taking tamoxifen?

The priority finding for a client taking tamoxifen that should be reported is leg tenderness. Tamoxifen is an anti-estrogen medication commonly used in the treatment of breast cancer. One of the serious risks associated with tamoxifen therapy is the potential for thromboembolic events, such as deep vein thrombosis (DVT) or pulmonary embolism. Leg tenderness can be a sign of thrombosis, especially if it is accompanied by swelling, redness, or warmth in the leg.

Monitoring for signs and symptoms of thromboembolic events is crucial in patients receiving tamoxifen due to these risks. Identifying and addressing potential complications early can lead to better patient outcomes. While hot flashes, gastrointestinal irritation, and vaginal dryness are known side effects of tamoxifen, they are generally considered less urgent compared to the risk of thromboembolic events indicated by leg tenderness.
