This case study analyzes the case of a 68-year-old female patient admitted to the emergency department with congestive heart failure (CHF) and a history of chronic renal failure (CRF). The assessment includes the patient's medical history, current vital signs, physical examination findings, and laboratory results. The analysis delves into the pathophysiology of CHF and CRF, exploring their interrelation and the impact on the patient's signs and symptoms. The case study identifies two priority nursing problems: decreased cardiac output and a deficiency of cognitive information. For each problem, the study establishes short-term and long-term goals, evidence-based nursing interventions, and expected outcomes. The nursing care plan includes monitoring vital signs, managing fluid intake, administering diuretics, and providing patient education. The assignment follows the Clinical Reasoning Cycle, including patient situation, cue collection, information processing, identifying nursing problems, establishing goals, and developing interventions. The case study highlights the importance of understanding the complex interplay between cardiac and renal function in providing effective patient care.
