High-Yield Clinical Antidotes & Toxicities
Rapid reference guide to life-saving antidotes, reversal agents, toxic ingestion protocols, and nursing monitoring parameters.
High-Yield Clinical Takeaways & NCLEX Priorities
- Opioids (morphine, fentanyl, oxycodone) -> Naloxone (Narcan). Note: Naloxone half-life is shorter than most opioids; monitor for re-sedation.
- Warfarin (Coumadin) -> Vitamin K (Phytonadione) and Fresh Frozen Plasma (FFP) for acute bleeding.
- Heparin / Enoxaparin -> Protamine Sulfate.
- Acetaminophen (Tylenol) -> N-Acetylcysteine (Mucomyst) within 8 hours of ingestion.
- Benzodiazepines -> Flumazenil (Romazicon) (Caution: Can precipitate acute seizures in dependent patients).
1. Medication Reversal Protocols
Reversal agents must be administered based on immediate clinical symptoms rather than laboratory delays. Repeated dosing of Naloxone is frequently required because the half-life of Naloxone is approximately 30 to 90 minutes, whereas long-acting opioids like methadone can persist for 24 to 36 hours.
