Choose A Clinical Situation In Your Specialty And Create A Theory From

Choose a clinical situation in your specialty and create a theory from your observations. Report the theory to the class. Use a form that clearly identifies your concepts and proposition such as; “psychosocial development (Concept A) progresses through (Proposition) stages (Concept B)». Identify and define the concepts involved and the proposition between them. For example, a surgical unit nurse may have observed that elevating the head of the bed for an abdominal surgery patient (Concept A) reduces (Proposition) complaints of pain (Concept B). The concepts are the head of the bed and pain. The proposition is that changing one will decrease the other. Raising the head of the bed decreases pain. Use current literature to define your concepts. Each concept should have at least two supporting references. Expectations Length: A minimum of 250 words, not including references Citations: At least one high-level scholarly reference in APA format from within the last 5 years Due 5/12/21

Paper For Above instruction

In the clinical setting of cardiology nursing, I have observed a potential relationship between patient activity levels and the incidence of arrhythmia episodes in post-myocardial infarction (MI) patients. Based on this observation, I propose a theory that physical activity (Concept A) influences arrhythmia frequency (Concept B), with the proposition that increased activity levels decrease the occurrence of arrhythmias. This theory aims to elucidate the role of controlled mobilization in improving cardiac stability and reducing complications in post-MI care.

The concept of physical activity encompasses any movement involving muscle effort, including supervised ambulation, prescribed exercises, and daily functional movements. Literature indicates that early mobilization post-MI can improve cardiovascular outcomes by enhancing myocardial oxygenation and reducing the risk of thrombus formation (Khan et al., 2021). Additionally, regular physical activity is associated with better autonomic regulation, which can decrease arrhythmogenic excitability in cardiac tissues (Li & Zhang, 2020). Supportive evidence highlights that moderate exercise enhances parasympathetic tone, thereby stabilizing cardiac rhythm (Kim et al., 2019).

Arrhythmia frequency refers to the number and severity of abnormal heart rhythms experienced by patients, including atrial fibrillation, ventricular tachycardia, or premature contractions. Literature supports the notion that heightened sympathetic activity and inactivity post-MI contribute to electrical instability within the myocardium (Thompson & Fung, 2022). Conversely, controlled physical activity has been shown to mediate autonomic function, reducing sympathetic dominance and promoting cardiac stability (Jones et al., 2021). Therefore, decreasing arrhythmia episodes through activity aligns with the concept that physiological modulation through mobilization influences cardiac electrical activity.

The proposition that increased physical activity reduces arrhythmia frequency is supported by evidence demonstrating that early supervised mobilization minimizes adverse cardiac events by improving myocardial oxygen supply-demand balance and autonomic regulation (Peters et al., 2020). It also emphasizes the importance of tailored activity programs to prevent excessive exertion, which could provoke arrhythmias. This theory integrates current understanding from cardiology literature and clinical observations, highlighting the potential for structured physical activity to serve as a non-pharmacologic intervention to promote cardiac stability after MI.
