Which of the following is TRUE about the ethical decision-making process?

• A. A decision could be made to remove an animal from a study.
• B. The lab technicians evaluate the situation and decide on a solution.
• C. The Institutional Animal Care and Use Committee (IACUC) is never involved.
• D. Researchers are involved only in certain situations.

Answer: (A)

Ethical decision-making in laboratory animal care focuses on protecting animal welfare while allowing legitimate scientific work, using humane endpoints and oversight to guide actions. If an animal shows signs of distress, illness, or if continuing in the study would cause unnecessary suffering, it is appropriate and often required to remove that animal from the study. This action reflects responsible care and is supported by the protocol approved by the IACUC and the veterinary team. While laboratory technicians are essential for monitoring animals and reporting concerns, they do not make the final call alone; decisions about welfare and study adjustments involve the research team, veterinarians, and the IACUC, all working within approved guidelines. Researchers are not limited to certain situations; they collaborate with oversight bodies to ensure welfare and compliance throughout the study. The idea that removal from a study cannot happen misstates how ethical safeguards operate in practice.
