Which of the following is NOT listed as high‑risk?

• A. Cytotoxic medicines
• B. Hormones
• C. Oil-based vaccines
• D. Vaccines

Answer: (D)

Understanding which medicines are considered high‑risk in a veterinary dispensary hinges on the potential for serious harm if they are mishandled and the level of precautions required. Cytotoxic medicines are high‑risk because they damage rapidly dividing cells, so exposure to staff or improper handling can have serious consequences. Hormones are also high‑risk due to their potent effects and the narrow margin between therapeutic and adverse outcomes, which demands precise dosing and strict storage and labeling. Oil‑based vaccines are treated as high‑risk because their adjuvanted, viscous formulations can present preparation and administration challenges, with risks related to stability, contamination, and local reactions. General vaccines, on the other hand, are not listed as high‑risk in this context; they’re handled with standard aseptic technique and do not carry the same level of toxicity or preparation risk as the other categories. Hence, vaccines are the item not listed as high‑risk.
