Which symptom is often associated with tranquilizer overdoses?

• A. Increased heart rate
• B. Severe respiratory depression
• C. Nausea and vomiting
• D. Euphoria and heightened sensory perception

Answer: (B)

Severe respiratory depression is a critical symptom often associated with tranquilizer overdoses. Tranquilizers, which are a category of central nervous system (CNS) depressants, can significantly slow down the respiratory rate and decrease the overall respiratory drive. This effect can lead to insufficient oxygen intake and an accumulation of carbon dioxide, posing a serious risk of respiratory failure and necessitating immediate medical attention.

While tranquilizers can have a variety of other symptoms and side effects, such as changes in heart rate or gastrointestinal distress, these are less typical indicators of overdose compared to respiratory depression. Additionally, symptoms like euphoria and heightened sensory perception are more commonly linked to stimulants rather than depressants like tranquilizers. Therefore, identifying severe respiratory depression in the context of an overdose situation is crucial for effective treatment and management.
