This nursing case study provides a comprehensive analysis of Congestive Heart Failure (CHF) through the lens of a patient, Mrs. Sharon McKenzie, who presents with symptoms like shortness of breath, swollen ankles, and elevated blood pressure. The analysis includes an outline of CHF, covering its causes, risk factors, and prevalence, followed by a discussion of common signs and symptoms along with their underlying pathophysiology. A detailed care plan is developed, focusing on interventions such as medication administration (enalapril and diuretics), fluid balance management, and oxygen therapy, with specific goals to decrease blood pressure, reduce fluid accumulation, and restore normal breathing patterns. The study also delves into the pharmacokinetics and pharmacodynamics of relevant medications, emphasizing their role in managing CHF and improving patient outcomes. This case study underscores the importance of holistic nursing care in managing complex conditions like CHF.
