A nurse knows that oxygen therapy in a myocardial infarction client primarily aims to:

In the context of oxygen therapy for a client experiencing a myocardial infarction, the primary goal is to improve oxygen saturation. When a patient has a myocardial infarction, the heart muscle is deprived of oxygen due to reduced blood flow, which can lead to tissue damage. Administering oxygen helps to increase the amount of oxygen available in the bloodstream, ensuring that vital organs receive the oxygen they need to function properly.

Increased oxygen saturation can help minimize further damage to the heart muscle and support the overall metabolic needs of the body during the event of a heart attack. By improving the oxygenation of the blood, the therapy can also enhance cardiac function and contribute to better outcomes for the patient. In this high-stress situation, while anxiety reduction, increasing blood flow, and pain management are also important aspects of care, the primary and immediate goal of oxygen therapy is to address the critical need for adequate oxygen supply.
