What is a primary nursing intervention for a patient with a myocardial infarction?

In the context of managing a patient with a myocardial infarction, administering oxygen and monitoring vital signs is a primary nursing intervention because it directly addresses the critical state of the patient's cardiac health. Myocardial infarction, commonly known as a heart attack, involves reduced blood flow to the heart muscle, which leads to ischemia and may result in serious complications.

Providing supplemental oxygen helps to ensure that the patient receives adequate oxygenation, which is essential since myocardial tissue can become damaged when deprived of oxygen. Additionally, monitoring vital signs—such as heart rate, blood pressure, respiratory rate, and oxygen saturation—allows healthcare providers to assess the patient’s stability, detect any changes in their condition, and respond promptly if the situation worsens. This real-time monitoring is crucial for effective intervention and ensuring patient safety.

Other options reflect important aspects of patient care but do not prioritize immediate, life-saving actions in the context of a myocardial infarction. While administering pain medication can improve a patient’s comfort, it does not address the underlying issue of low oxygenation and hemodynamic stability. Encouraging ambulation immediately would not be appropriate, as physical activity could exacerbate the patient's condition right after a myocardial event. Lastly, starting a low-fat diet is a long
