Case Study: Mrs. R.

It is necessary for an RN-BSN-prepared nurse to demonstrate an enhanced understanding of the pathophysiological processes of disease, the clinical manifestations and treatment protocols, and how they affect clients across the life span.

Evaluate the Health History and Medical Information for Mrs. R., presented below.

Health History and Medical Information

Mrs. R. is a 68-year-old married woman who has a history of hypertension, chronic heart failure, and chronic obstructive pulmonary disease (COPD). Despite requiring 2L of oxygen/nasal cannula at home during activity, she continues to smoke two packs of cigarettes a day and has done so for 40 years. Three days ago, she had sudden onset of flu-like symptoms, including fever, productive cough, nausea, and malaise. Over the past 3 days, she has been unable to perform ADLs and has required assistance in walking short distances. She has not taken her antihypertensive medications or medications to control her heart failure for 3 days. Today, she has been admitted to the hospital ICU with acute decompensated heart failure and acute exacerbation of COPD.

Subjective Data

1. Is very anxious and asks whether she is going to die.

2. Denies pain but says she feels like she cannot get enough air.

3. Says her heart feels like it is “running away.”

4. Reports that she is exhausted and cannot eat or drink by herself.

Objective Data

5. Height 175 cm; Weight 95.5kg.

Critical Thinking Table – Mrs. R.

Clinical Manifestations

Subjective Findings:

Anxiety and fear about dying → emotional response to severe illness and dyspnea.
Dyspnea: “Feels like she cannot get enough air” → hallmark of acute decompensated heart failure (ADHF) and COPD exacerbation.
Palpitations: “Heart feels like it is running away” → consistent with atrial fibrillation.
Fatigue and inability to perform ADLs → decreased cardiac output and hypoxia.
Nausea and malaise → systemic effects of heart failure and infection.

Objective Findings:

Vital signs: Tachycardia (HR 118–132, irregular), hypotension (BP 90/58), tachypnea (RR 34), SpO₂ 82% → indicate hypoxemia and cardiac compromise.
Cardiovascular: Distant S1/S2, S3 gallop, peripheral edema, JVD → fluid overload and decreased left ventricular function.
Respiratory: Crackles, decreased breath sounds, frothy blood-tinged sputum → pulmonary edema from ADHF; COPD exacerbation signs.
Gastrointestinal: Hepatomegaly → right-sided heart failure congestion.
Weight/BMI: 95.5 kg, 175 cm → overweight, contributing to cardiovascular strain.

Cardiovascular Conditions Leading to Heart Failure

Conditions and Comorbidities:

Hypertension → chronic pressure overload; left ventricular hypertrophy → diastolic dysfunction → HFpEF.
Chronic Heart Failure → ongoing remodeling, decreased contractility → exacerbations.
Atrial Fibrillation → irregular ventricular response → decreased cardiac output, increased thromboembolism risk.
Coronary Artery Disease (possible) → atherosclerosis → ischemia → impaired myocardial function.

How They Increase HF Risk:

Each condition either increases myocardial workload, decreases perfusion, or promotes maladaptive remodeling → reduced cardiac efficiency.

Prevention/Intervention:

Condition	Nursing/Medical Intervention
Hypertension	Monitor BP, adjust antihypertensives, lifestyle counseling (low-salt diet, exercise).
Chronic HF	Daily weight monitoring, fluid restriction, adherence to medications (ACE inhibitors, diuretics).
Atrial Fibrillation	Rate/rhythm control (beta-blockers), anticoagulation, monitor for palpitations.
Coronary Artery Disease	Lipid management, smoking cessation, cardiac rehab referral.

Evaluation of Nursing Interventions at Admission

Initial Assessments & Interventions:

Vital signs, oxygen therapy, cardiac and respiratory assessment, IV medication initiation → appropriate and beneficial.
Medications (diuretics, ACE inhibitors, beta-blockers, bronchodilators) targeted fluid overload, hypertension, and airway compromise.
Cardiac monitoring revealed atrial fibrillation → early detection of arrhythmia complications.

Recommended Changes for Independence & Readmission Prevention:

Early involvement of respiratory therapy for oxygen titration and pulmonary rehab.
Dietitian consult for low-sodium diet education.
Education on medication adherence and self-monitoring of weight, BP, and oxygen saturation.
Discharge planning should include home health services to assist ADLs and monitor for early signs of exacerbation.

Medications and Polypharmacy Prevention

Medication	Class	Action	Rationale
Furosemide (Lasix)	Loop diuretic	Increases renal excretion of sodium/water	Reduces pulmonary and peripheral edema in HF and COPD fluid overload
Enalapril (Vasotec)	ACE inhibitor	Vasodilation, decreases afterload, inhibits remodeling	Improves cardiac output and prevents further HF progression
Metoprolol (Lopressor)	Beta-blocker	Slows HR, reduces myocardial oxygen demand	Controls AF, reduces BP, prevents HF exacerbations
Morphine sulfate (IV)	Opioid	Vasodilation, reduces anxiety	Alleviates dyspnea and preload in acute pulmonary edema
ProAir HFA	Short-acting beta2 agonist	Bronchodilation	Relieves bronchospasm during COPD exacerbation
Flovent HFA	Inhaled corticosteroid	Reduces airway inflammation	Prevents exacerbation of COPD
Oxygen 2L NC	Supplemental oxygen	Improves oxygenation	Addresses hypoxemia due to COPD exacerbation and pulmonary edema

Nursing Interventions to Prevent Polypharmacy Problems:

Review all medications for interactions before administration.
Maintain an updated medication reconciliation list at admission and discharge.
Educate patient/caregiver on indications and side effects.
Schedule regular lab monitoring (renal function, electrolytes) to detect adverse effects early.

Health Promotion and Restoration Teaching Plan

Steps for Transition to Subacute Care:

Stabilize acute symptoms (oxygenation, fluid balance, arrhythmia control).
Engage multidisciplinary team: cardiology, pulmonology, nutrition, physical therapy, respiratory therapy.
Educate patient on medication adherence, lifestyle modification (smoking cessation, low-sodium diet, fluid management).
Implement home health visits for monitoring and support ADLs.

Alternative Discharge Options:

Skilled nursing facility for continued monitoring.
Home health with visiting nurse services.
Pulmonary/cardiac rehab programs for functional restoration.

Rehabilitation Resources Impact:

Medication management prevents readmission.
Pulmonary rehab improves oxygen tolerance and exercise capacity.
Nutritional counseling assists with weight and sodium management.

Pathophysiological Changes from Long-Term Tobacco Use

Chronic inflammation → airway remodeling, mucous hypersecretion → COPD progression.
Endothelial dysfunction → accelerates atherosclerosis → increased cardiovascular risk.
Impaired immune function → higher susceptibility to infections → triggers HF exacerbation.

COPD Triggers and Smoking Cessation Options

COPD Triggers:

Smoking, respiratory infections, environmental pollutants, allergens, cold air.

Smoking Cessation Options:

Behavioral counseling (individual or group therapy).
Nicotine replacement therapy (patches, gum).
Prescription medications (bupropion, varenicline).
Regular follow-up and motivational interviewing to prevent relapse.
