Which medication is specifically mentioned as not for routine use in ACS due to diminishing antiplatelet effects?

  1. Morphine

  2. Oxygen

  3. Nitrates

  4. Aspirin

The correct answer is: Morphine

While other medications such as oxygen, nitrates and aspirin may be used for patients experiencing acute coronary syndrome (ACS), morphine is not recommended for routine use due to diminishing antiplatelet effects. This is because morphine has been shown to increase mortality rates and delay cardiac catheterization procedures in ACS patients. It is typically only used for severe chest pain that is not relieved by nitroglycerin or morphine. Therefore, morphine is the best choice for the option that is not typically used for routine treatment in ACS.
