Final answer:
In the case of suspected acute myocardial infarction, the nurse should administer oxygen at 2L per minute via nasal cannula and establish intravenous access with a large-bore catheter for potential immediate intervention, prioritizing actions that can have a direct impact on patient survival and stabilization.
Step-by-step explanation:
When a client is admitted to the emergency department with complaints of crushing chest pain and symptoms that might indicate an acute myocardial infarction (MI), it is critical to follow protocols designed for rapid assessment and intervention. The first action in such cases typically involves initiating treatment to stabilize the patient's condition. Administering oxygen is a crucial step to ensure tissue perfusion and oxygenation, particularly when the heart's ability to supply blood is compromised. A stat electrocardiogram (EKG or ECG) has been obtained, which suggests that the nurse is already responding to the potential for acute cardiovascular issues.
Based on the guidelines and information provided, it's evident that the nurse should prioritize interventions that are lifesaving and can have immediate impact on the patient's cardiovascular status. Therefore, establishing intravenous access using a large-bore catheter would be the next course of action. This would provide a means for rapid administration of medications, fluids, or blood products as needed. Secondary actions, such as a full medical history or pupil checks, while important, are not as immediate in the management of a suspected MI. In the event of cardiac arrest, knowledge of cardiopulmonary resuscitation (CPR) emphasizing high-quality chest compressions would be essential.
