This case study provides a detailed analysis of congestive cardiac failure in a 77-year-old woman, Mrs. Sharon McKenzie, whose condition is primarily attributed to hypertension and a history of myocardial infarction. The analysis covers the causes, incidence, and risk factors associated with congestive cardiac failure, particularly in elderly patients, highlighting the impact on both the patient and their family. It identifies common signs and symptoms, linking them to their underlying pathophysiology, and discusses two common drug classes used in treatment: ACE inhibitors and beta-blockers, explaining their physiological effects. Furthermore, the case study outlines essential nursing care strategies, including supportive care, management of electrolyte imbalances, and hemodynamic compromise, emphasizing the importance of regular monitoring and medication adjustments. The solution refers to the appropriate treatment of bradycardia, as revealed by the ECG report, and provides relevant references to support the analysis and recommendations.
