In depressant toxicity, which action is initially taken?

• A. Ensure patent airway.
• B. Obtain drug levels.
• C. Gastric lavage
• D. Administer antidotes

Answer: (A)

Securing an open airway and supporting breathing is the first priority in depressant overdose. These substances blunt the central drive to breathe and can impair airway protective reflexes, leading to hypoventilation, low oxygen levels, and risk of aspiration. Providing oxygen, suctioning as needed, and preparing for advanced airway support or ventilation ensures the patient maintains adequate oxygen delivery while the toxins are managed. Checking drug levels won’t change the immediate crisis—they take time and don’t reverse the acute respiratory depression. Gastric lavage is rarely useful in depressant overdoses, carries risks, and is generally not the initial step unless specific, critical circumstances exist. Antidotes are only useful for certain substances and aren’t universally applicable, so they don’t replace the need for airway and ventilation support.
