Which client problem has priority for the client with cardiac dysrhythmia?

Choice A rationale Activity intolerance is a common nursing diagnosis for patients with dysrhythmias because the heart cannot effectively increase the heart rate or stroke volume to meet the oxygen demands of the body during physical exertion. While this affects the patient's quality of life and ability to perform daily tasks, it is not an immediate threat to life. It is a secondary consequence of the primary physiological failure occurring within the cardiac conduction system and pump mechanism. Choice B rationale Impaired gas exchange can occur if a dysrhythmia leads to acute heart failure and pulmonary congestion, which interferes with the diffusion of oxygen and carbon dioxide at the alveolar-capillary membrane. However, the gas exchange problem is usually a result of the heart's inability to move blood forward. Addressing the underlying cardiac output is the more direct way to solve the resulting respiratory issues in a patient whose primary diagnosis is a heart rhythm disturbance. Choice C rationale Alteration in comfort, often manifesting as palpitations, chest pressure, or anxiety, is frequently reported by patients experiencing dysrhythmias. While managing pain and distress is a core tenet of nursing care, it does not address the hemodynamic stability of the patient. In the hierarchy of needs, physiological stability and vital organ perfusion take precedence over comfort measures, especially when a dysrhythmia has the potential to become lethal or cause systemic collapse. Choice D rationale Decreased cardiac output is the priority because dysrhythmias directly impair the heart's ability to pump an adequate volume of blood to meet metabolic demands. Whether the heart is beating too fast to allow for adequate ventricular filling or too slow to maintain systemic pressure, the end result is reduced perfusion to vital organs like the brain and kidneys. Ensuring sufficient cardiac output is essential to prevent cardiogenic shock, organ failure, and death in the cardiac patient.
