What side effect should a nurse monitor in a client taking aspirin for osteoarthritis?

When a client is taking aspirin, particularly for conditions like osteoarthritis, one important side effect to monitor for is tinnitus. Tinnitus is characterized by a ringing or buzzing in the ears and can occur as a result of salicylate toxicity, which is associated with high doses of aspirin or prolonged use. This side effect is particularly significant because it may indicate that the levels of aspirin in the body are too high and could lead to further complications.

Monitoring for tinnitus is essential as it can lead to a decreased quality of life and may warrant a reevaluation of the dosage or consideration of alternative pain management strategies. Recognizing this side effect can help in preventing more serious toxicity, including hearing loss, which can occur if aspirin use is not carefully monitored. Understanding this risk allows nurses to educate patients about the signs to watch for and to ensure safe use of the medication.
