I’m working on a writing multi-part question

I’m working on a writing multi-part question and need an explanation to help me study. A 65-year-old patient is 8 days post-op after a total knee replacement. The patient suddenly complains of shortness of breath, pleuritic chest pain, and palpitations ( PULMONARY EMBOLISM ) . On arrival to the emergency department, an EKG revealed new-onset atrial fibrillation and right ventricular strain pattern T wave inversions in the right precordial leads (V1-4) ± the inferior leads (II, III, aVF). Develop a 1- to 2-page case study analysis, examine the patient symptoms presented in the case study. Be sure to address the following:Explain both the cardiovascular and cardiopulmonary pathophysiologic processes of why the patient presents these symptoms. Explain how the cardiovascular and cardiopulmonary pathophysiologic processes interact to affect the patient. Explain any racial/ethnic variables that may impact physiological functioning.
