What are the only 12 therapeutic drugs which may be administered within 24 hours of showing?

• A. Phenylbutazone, Diclofenac (Surpass), Flunixin, Ketoprofen, Meclofenamic Acid, Naproxen, Firocoxib (Equioxx), Acetazolamide, Furosemide or Lasix, Isoxsuprine, Lidocaine/Mepivicaine, Dexamethasone
• B. A random subset of NSAIDs not meeting the list
• C. A list excluding Dexamethasone
• D. A list including non-therapeutic drugs only

Answer: (A)

This question tests your knowledge of the fixed set of drugs that are allowed to be administered within 24 hours of showing. The official rulebook lists twelve therapeutic substances that may be given in that 24-hour window, and the exact set includes six NSAIDs (phenylbutazone, diclofenac, flunixin, ketoprofen, meclofenamic acid, naproxen), plus firocoxib, acetazolamide, furosemide, isoxsuprine, lidocaine/mepivacaine, and dexamethasone. That precise combination matches the permitted list, so it is the correct option.

The other statements don’t fit because they either imply a random subset of NSAIDs, omit an item that is on the allowed list, or suggest a list that consists only of non-therapeutic drugs. None of those align with the rulebook’s specified twelve drugs.
