What were the side effects of ether?

• A. Dizziness and nausea
• B. Vomiting etc
• C. Seizures
• D. No side effects

Answer: (B)

Ether, used as an early general anaesthetic, commonly irritated the airways and stomach. This led to frequent vomiting and nausea, sometimes along with coughing or other distress during and after the procedure. Because vomiting was such a common and well-documented reaction, describing the side effects as vomiting and related symptoms best fits the historical reality of ether use. Other options either underestimate the range of reactions (dizziness and nausea alone) or imply effects that were not typical (seizures), or claim no side effects at all.
