Administering oxygen to a client with a coronary occlusion experiencing chest pain primarily aims to increase the oxygen concentration in the heart cells. In the case of a coronary occlusion, the heart muscle may not be receiving adequate blood supply due to blockage in the coronary arteries. This can lead to ischemia, where the heart tissue does not receive enough oxygen to function properly. By providing supplemental oxygen, the goal is to enhance the oxygen availability to the myocardium, which can help alleviate pain and reduce the risk of further myocardial damage.

While preventing dyspnea and cyanosis are important aspects of patient care, they are secondary to the primary goal of ensuring that the heart receives enough oxygen to prevent ischemic injury. Similarly, increasing oxygen tension in the circulating blood is a related concept, but it does not directly address the immediate need of the heart cells in the context of an occlusion. Increasing oxygen concentration specifically targets the metabolic needs of the heart muscle during a period of compromised blood flow.
