Case Study Scenario
Chief Complaint
A.C., is a 61-year old male with complaints of shortness of breath.
History of Present Illness
A.C. was seen in the emergency room 1 week ago for an acute onset of mid-sternal chest pain. The event was preceded with complaints of fatigue and increasing dyspnea for 3 months, for which he did not seek care. He was evaluated by cardiology and underwent a successful and uneventful angioplasty prior to discharge. Despite the intervention, the shortness of breath has not improved. Since starting cardiac rehabilitation, he feels that his breathlessness is worse. The cardiologist has requested that you, his primary care provider, evaluate him for further work-up. Prior to today, his last visit with your practice was 3 years ago when he was seen for acute bronchitis and smoking cessation counseling.

Case Study Questions
Pathophysiology & Clinical Findings of the Disease

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

Management of the Disease
*Utilize the required Clinical Practice Guideline (CPG) to support your treatment recommendations.

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

Solution:
Pathophysiology & Clinical Findings of the Disease

Are the spirometry results consistent with an obstructive or restrictive pulmonary disease? What is the most likely pulmonary diagnosis for this patient?

The spirometry results are consistent with obstructive disease, with the most probable pulmonary being COPD(chronic obstructive pulmonary disease), particularly Emphysema.

Explain the pathophysiology associated with the chosen pulmonary disease.

The underlying disease process that causes COPD development and the presenting signs and symptoms include inflammation and narrowing of the peripheral airway, reduced FEV1 and parenchymal destruction due to emphysema which leads to limited airflow, and loss of the small airways which causes airflow limitation (Lowe et al., 2019)…..Click Icon below to purchase full tutorial at $10
