Final answer:
The most appropriate nursing intervention to delegate for a patient who had an AMI 3 days ago is the administration of metoprolol and aspirin.
Step-by-step explanation:
The most appropriate nursing intervention to delegate to an experienced LPN/LVN for a patient who had an AMI 3 days ago is the administration of the ordered metoprolol (Lopressor) and aspirin.
Metoprolol is a beta-blocker medication used to reduce heart rate and blood pressure, while aspirin helps to prevent blood clot formation.
Administering these medications is within the scope of practice for an experienced LPN/LVN under the supervision of the Registered Nurse (RN).
