- 2 and 4
- 1, 2 and 3
Show Solution
The Correct Option is B
Solution and Explanation
The fastest way through this is to sort the four listed drugs into relevant and irrelevant before matching to a code.
- Vitamin K: relevant. It is the specific antidote that restores production of the clotting factors warfarin suppresses.
- Naloxone: irrelevant. It is the opioid-overdose reversal agent and has nothing to do with anticoagulant bleeding.
- Fresh frozen plasma: relevant. It supplies ready-made clotting factors for immediate control of active bleeding while vitamin K takes effect over several hours.
- N-acetylcysteine: irrelevant. It is the paracetamol-overdose antidote, unrelated to warfarin toxicity.
With naloxone and N-acetylcysteine eliminated, only vitamin K and fresh frozen plasma remain, matching code 1 and 3.
Correct answer: 1 and 3 (Vitamin K and Fresh frozen plasma)
