Which clinical indicators of aspirin toxicity should the nurse advise the client to report?

Aspirin toxicity can lead to serious complications, one of which includes gastrointestinal bleeding. The presence of blood in the stool is a significant clinical indicator that should raise concern. This could suggest that the aspirin is causing irritation or erosion in the gastrointestinal tract, leading to bleeding. In this context, it is crucial for clients to report such symptoms immediately, as they may require urgent medical evaluation and intervention.

Joint pain, increased heart rate, and fatigue, while concerning, are more general symptoms that may not be directly indicative of aspirin toxicity. Joint pain could be related to various conditions, increased heart rate may occur due to numerous factors including anxiety or dehydration, and fatigue is a common symptom in many illnesses. However, the presence of blood in the stool is a direct red flag for potentially severe complications that require prompt attention.
