Which finding may indicate stimulant overdose?

• A. Shortness of breath
• B. Rapid pulse
• C. Nausea
• D. Sweating without tachycardia

Answer: (B)

Stimulant overdose drives the body's fight-or-flight response, pushing the heart to work harder by flooding the body with norepinephrine and dopamine. A rapidly increasing heart rate is a common, early sign because these substances directly boost cardiac chronotropy, often along with high blood pressure and sweating. While shortness of breath, nausea, or sweating without a fast heart rate can appear in various conditions, they are less specific for overdose. Tachycardia specifically reflects the cardiac stress from stimulants and signals a need for close monitoring and stabilization to prevent complications like arrhythmias or ischemia.
