Read the case study below and refer to the grading rubric. Using the Week 3 Case Study Template, respond to the case study questions. Incorporate at least one scholarly reference to support pathophysiology statements, using the course textbook or relevant evidence-based journal sources. Employ the current Clinical Practice Guideline (GOLD Criteria) for COPD management to classify disease severity and recommend treatment. Utilize appropriate medication references such as Epocrates to identify medication names. Ensure all responses follow proper APA formatting, including in-text citations, references, correct spelling, grammar, and English language use.

Case Study Scenario:

Chief Complaint: A.C., 61-year-old male, reports shortness of breath.

History of Present Illness: He experienced acute mid-sternal chest pain a week ago, preceded by fatigue and increasing dyspnea over 3 months. He underwent successful angioplasty but symptoms persist and worsen with cardiac rehab. Last visit 3 years ago was for bronchitis and smoking cessation counseling.

Past Medical History: Hypertension, hyperlipidemia, coronary artery disease, smoker.

Family History: Father's early death from acute coronary syndrome, mother and sister with breast cancer, children with no significant issues.

Social History: 35-pack-year smoking history, recent reduction to one cigarette at bedtime, no alcohol or recreational drug use. Occupation: real estate agent.

Allergies: No known drug allergies.

Medications: Rosuvastatin 20 mg, Carvedilol 25 mg BID, Hydrochlorothiazide 12.5 mg daily, Aspirin 81 mg daily.

Review of Systems: Fatigue, exertional dyspnea, dry morning cough, no fever, chills, weight loss, or chest pain. No wheezing on auscultation but bilateral wheezes with forced expiration noted.

Physical Exam: Alert, no distress, vital signs: BP 120/84, T 97.9°F, HR 62, RR 22, SaO₂ 93%. Lungs: hyperinflated, flattened diaphragm, bilateral wheezes. Heart: regular rhythm, no murmurs. Skin: dry, pale, no clubbing.

Chest X-Ray: Hyperinflated lungs, no effusions or infiltrates.

Spirometry: (Sample values to interpret efficiency and pattern; actual figures needed for diagnosis)

Using this case, answer the following questions:

Pathophysiology & Clinical Findings of the Disease

  1. Are the spirometry results consistent with obstructive or restrictive pulmonary disease? What is the most likely pulmonary diagnosis for this patient?
  2. Explain the pathophysiology associated with the chosen pulmonary disease.
  3. Identify at least three subjective findings from the case which support the chosen diagnosis.
  4. Identify at least three objective findings from the case which support the chosen diagnosis.

Management of the Disease

  1. Classify the patient's disease severity. Is this considered stable or unstable?
  2. Identify two “Evidence A” recommended medication classes for the treatment of this condition and provide an example (drug name) for each.
  3. Describe the mechanism of action for each of the medication classes identified above.
  4. Identify two “Evidence A” recommended non-pharmacological treatment options for this patient.

Organization, spelling, grammar & APA format

Use the Week 3 case study template, include proper in-text citations matching the reference list, and ensure minimal spelling, grammar, and formatting errors.

Paper For Above instruction

Chronic Obstructive Pulmonary Disease (COPD) represents a prevalent and progressive lung disease characterized by airflow limitation that is not fully reversible. It predominantly involves a combination of emphysema and chronic bronchitis, which contribute to airflow obstruction and impaired gas exchange (GOLD, 2023). The case details, including spirometry findings, clinical presentation, and physical exam, suggest a diagnosis of COPD, particularly given the patient's history of smoking, exertional dyspnea, wheezing, and hyperinflated lungs on chest radiograph.

Pathophysiology & Clinical Findings of the Disease

The spirometry results, indicative of a decreased FEV1/FVC ratio (

The most likely diagnosis is moderate to severe COPD, given the clinical presentation and radiological findings. The hyperinflation seen on the chest X-ray, along with wheezing and prolonged expiration, further supports this diagnosis. Pathophysiologically, chronic exposure to cigarette smoke leads to oxidative stress and inflammation, promoting mucus hypersecretion, airway remodeling, and destruction of alveolar walls, which diminish elastic recoil and increase residual volume (Hogg et al., 2019).

Subjective findings supporting this diagnosis include:

  • Exertional dyspnea, which aligns with airflow restriction.
  • Dry morning cough due to increased mucus production.
  • History of smoking and ongoing symptoms despite prior intervention.

Objective findings supporting the diagnosis include:

  • Bilateral wheezing and prolonged expiratory phase on auscultation.
  • Hyperinflated lungs and flattened diaphragm on chest X-ray.
  • Reduced oxygen saturation (93%), indicating impaired gas exchange.

Management of the Disease

The patient's COPD severity classification, according to the GOLD criteria, likely falls into a moderate (GOLD 2) or severe (GOLD 3) category based on spirometric measurements, symptom burden, and exacerbation risk. Currently, the presentation suggests a stable disease, although symptoms are worsening, warranting close monitoring.

Evidence-based pharmacologic treatment recommends the use of long-acting bronchodilators, such as long-acting muscarinic antagonists (LAMAs) and long-acting beta-agonists (LABAs), which have demonstrated significant benefits. For example:

  • Long-Acting Muscarinic Antagonists (LAMA): Tiotropium
  • Long-Acting Beta-Agonists (LABA): Salmeterol

The mechanism of action involves bronchodilation through different pathways: Tiotropium blocks M3 muscarinic receptors, leading to smooth muscle relaxation and airway dilation (Kenny et al., 2021). Salmeterol stimulates beta-2 adrenergic receptors, enhancing cyclic AMP levels and causing bronchodilation (Barnes, 2017).

Non-pharmacological treatment options supported by evidence include smoking cessation programs, which significantly slow disease progression, and pulmonary rehabilitation programs that improve exercise capacity and quality of life (GOLD, 2023).

Conclusion

In conclusion, the patient's clinical presentation and diagnostic findings are consistent with a diagnosis of COPD, primarily obstructive in nature. Pathophysiologically, chronic inflammation from smoking leads to airway remodeling and alveolar destruction. Disease classification guides treatment, emphasizing non-pharmacological interventions alongside evidence-based pharmacotherapy. Ongoing monitoring and patient education remain integral to effective management and improving outcomes.
