Final answer:
Complaints indicative of aspirin intoxication include stomach pain, symptoms of stomach bleeding, tinnitus, headaches, and confusion. Excessive use of aspirin can lead to serious side effects like renal damage, especially in individuals with certain health factors.
Step-by-step explanation:
A client who is suspected of aspirin intoxication might exhibit various symptoms, the most revealing being complaints related to gastrointestinal distress, such as stomach pain or symptoms suggestive of stomach bleeding. Overdose of aspirin, or acetylsalicylic acid, can result in symptoms like tinnitus (ringing in the ears), headaches, dizziness, confusion, and respiratory alkalosis (increased blood pH due to excessive breathing out of carbon dioxide), among others.
It's crucial to monitor for signs of serious side effects like stomach bleeding especially when aspirin is taken in high doses or over an extended period. Given that aspirin is a non-steroidal anti-inflammatory drug (NSAID) regular and excessive consumption can lead to an increased risk of renal damage or impairments which is particularly concerning for specific groups including individuals over 60 years of age or those with pre-existing conditions such as high blood pressure, heart disease, or kidney disease. Therefore, any complaint that suggests these symptoms could indicate aspirin intoxication and warrant immediate medical attention.
