Which finding is associated with aspirin overdose and supports hyperventilation?

• A. Slow breathing
• B. Normal respiration
• C. Hyperventilation to blow off acidosis
• D. Rapid breath-holding

Answer: (C)

Aspirin (salicylate) overdose commonly stimulates the respiratory center, so the patient breathes faster and more deeply. This hyperventilation lowers the carbon dioxide level in the blood, producing a respiratory alkalosis early in the course. The rapid, shallow breathing you observe is the body’s response to the toxin and is the clue that supports this mechanism. So, recognizing rapid, increased breathing as the finding aligns with aspirin poisoning, because it reflects the hyperventilation that blows off CO2. Slow breathing or normal breathing wouldn’t indicate this stimulant effect, and rapid breath-holding would raise CO2 rather than decrease it, which doesn’t fit the pattern of early salicylate toxicity.
