Mrs. J., a 63-year-old woman with a history of hypertension, heart failure, and COPD, was admitted to the ICU with acute decompensated heart failure after experiencing flu-like symptoms and worsening respiratory distress. She continues to smoke heavily despite her conditions and has not taken her medications for three days, leading to critical health issues evidenced by vital signs indicating severe cardiovascular stress. The assignment requires a critical evaluation of her clinical manifestations, nursing interventions, medication rationale, preventive measures for heart failure, management of drug interactions, an educational teaching plan, and smoking cessation options.
