Which medication is indicated if the patient with chest discomfort has persistent symptoms after one or more doses of NTG?

• A. Morphine 4 mg
• B. Aspirin 325 mg
• C. Nitroglycerin 0.4 mg again
• D. Fentanyl 25 mcg

Answer: (D)

When chest pain persists after nitroglycerin, the next goal is to relieve the patient's pain and reduce sympathetic drive, which helps lower myocardial oxygen demand. An opioid analgesic is used for this, and among common EMS options, fentanyl is preferred because it acts quickly, is easy to titrate, and tends to have a more favorable hemodynamic profile than morphine (less histamine release and hypotension risk). A typical approach is IV fentanyl 25 mcg, repeated as needed with careful monitoring of blood pressure, heart rate, and respiration. While aspirin and nitroglycerin have important roles in ACS management, they don’t directly address ongoing pain in the moment, and repeating nitroglycerin isn’t always appropriate if the patient remains uncomfortable or if blood pressure is a concern. The chosen option provides prompt, controllable pain relief to help stabilize the patient while monitoring for further changes.
