In protocol review, what must be justified regarding pain?

• A. Expected pain levels and mitigation strategies.
• B. The number of authors on the protocol.
• C. The color of the cage.
• D. Only the cost of analgesia.

Answer: (A)

The main concept here is that protocol review focuses on how pain and distress will be anticipated and managed. In a thorough protocol, you must justify the expected pain associated with procedures and lay out concrete plans to minimize that pain. This includes specifying analgesia or anesthesia to be used, how and when it will be administered, dosing rationale, and any refinements to procedures that reduce suffering. It also involves outlining humane endpoints and monitoring plans in case pain becomes unmanageable, as well as considering alternatives to procedures that might cause pain.

This approach is essential because it directly addresses animal welfare and the integrity of the research, aligning with regulatory and institutional requirements to prevent unnecessary suffering and to refine practices for better science. The other topics listed—how many authors are on the protocol, the color of the cage, or the cost of analgesia alone—do not address how to control pain or comply with welfare standards in the protocol review.
