Which event is an adverse event in humans exposed to animal drugs and devices?

• A. Needle-stick injuries
• B. Enhanced immune response
• C. Improved tolerance
• D. Stable vital signs

Answer: (A)

An adverse event is any undesirable experience that occurs after a person is exposed to a drug, product, or device. In this context, the most fitting adverse event is needle-stick injuries. Handling needles or administering injections with animal drugs or devices can cause physical harm, pain, tissue damage, or potential infection—harm that qualifies as an adverse event. The other options describe outcomes that would be beneficial or neutral (enhanced immune response, improved tolerance, stable vital signs) and are not inherently adverse events.
