What is the recommended adult dosage of Atropine?

• A. 0.5 mg IV/IO
• B. 1 mg IV/IO
• C. 2 mg IV/IO
• D. 3 mg IV/IO

Answer: (B)

Atropine is commonly used in emergency settings, particularly for the treatment of bradycardia and certain types of poisoning. The recommended adult dosage of atropine is typically 1 mg administered intravenously (IV) or intraosseously (IO). This dosage is effective in increasing heart rate by blocking the action of the vagus nerve on the heart, which helps relieve symptoms associated with bradycardia. The administration of 1 mg allows for a sufficient pharmacological effect, and further doses can be administered every 3-5 minutes if necessary, up to a total of 3 mg. Dosing at this level is well-studied and aligns with clinical guidelines for treating bradyarrhythmias in adults. Lower or higher dosages may not achieve the desired therapeutic effect or may lead to excessive anticholinergic effects, which can complicate treatment.
