Which of the following is NOT among the 12 therapeutic drugs that may be administered within 24 hours of showing?

• A. Dexamethasone
• B. Penicillin
• C. Diclofenac (Surpass)
• D. Naproxen

Answer: (B)

The test is asking which drug is not included in the approved 24-hour therapeutic list. This list covers certain anti-inflammatories and steroids that may be administered within 24 hours of showing under the rules. Dexamethasone is a corticosteroid and commonly appears on that list. Diclofenac (Surpass) and Naproxen are NSAIDs also typically included as permitted therapies within the window. Penicillin is an antibiotic, and antibiotics are not part of the 12 therapeutics allowed within 24 hours. Administering penicillin in that short window would violate the rule, since antibiotics require a longer withdrawal or aren’t permitted under the same 24-hour allowance.
