Final answer:
The priority medications for a client with a myocardial infarction include supplemental oxygen, aspirin, and nitroglycerine for immediate treatment. Thrombolytic agents and heparin are used for longer-term care, with invasive procedures like angioplasty and bypass surgery as necessary.
Step-by-step explanation:
Priority Medication Administration for Myocardial Infarction
The priority medications for a client who has suffered a myocardial infarction (MI) include the following. Immediate treatments are essential and start with administering supplemental oxygen to improve tissue oxygenation. Additionally, aspirin is given to help break up blood clots, which is critical in the management of MI due to its antiplatelet effects. Another pivotal medicine is nitroglycerine, which is administered sublingually to quickly absorb and help dilate coronary vessels, decreasing chest pain and improving blood flow to the heart muscle.
For more prolonged treatment, thrombolytic agents like streptokinase can dissolve the clot. The anticoagulant heparin may be given to prevent further clotting. Invasive procedures such as balloon angioplasty with stenting or bypass surgery may be necessary to restore blood flow. In severe cases, coronary replacement or the use of a coronary assist device may be considered when the damage to the heart is extensive.
