Question

Which of the following is NOT a characteristic symptom of emphysema?

A SUBRAMANYAM · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Emphysema symptoms
 **Related Topics**: Chronic Obstructive Pulmonary Disease (COPD), respiratory system
 **Prerequisites**: Basic understanding of respiratory physiology
## SOLUTION PATHWAY
**Given Information**:
  The question asks to identify a symptom that is NOT characteristic of emphysema.
  Options provided: Shortness of breath, wheezing, increased lung elasticity, chronic cough.
**Method & Steps**:
 1. Analyze each option to determine if it's a typical symptom of emphysema.
  Reasoning: Emphysema is a chronic lung disease characterized by the destruction of alveoli (air sacs) leading to reduced lung elasticity and impaired airflow.
 2. Evaluate the options:
  Shortness of breath (dyspnea): A hallmark symptom of emphysema due to reduced lung capacity.
  Wheezing:  Often present due to airflow obstruction in the bronchioles.
  Increased lung elasticity:  Incorrect. Emphysema causes a *decrease* in lung elasticity.
  Chronic cough: Common, often productive (with mucus).
 3. Identify the non-characteristic symptom:
  Result: Increased lung elasticity is NOT a characteristic symptom of emphysema.
  Verification: The other options are all consistent with the pathophysiology of emphysema.
 ## OPTION ANALYSIS
A :x: Shortness of breath is a key symptom of emphysema.
B :x: Wheezing is a common symptom associated with airflow limitations in emphysema.
C ✓: Increased lung elasticity is incorrect.  Emphysema causes a *loss* of lung elasticity.
D :x: A chronic cough is a frequent symptom of emphysema.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing emphysema with other respiratory conditions:  Asthma and bronchitis share some overlapping symptoms but differ in their underlying mechanisms.
  2.Overlooking the key pathophysiological feature of emphysema:  Reduced lung elasticity is crucial to understanding the symptoms.
 **Quick Tips**:
  1.Remember the key features of emphysema: decreased lung elasticity, shortness of breath, chronic cough, and often wheezing.
  2.Use mnemonics or visual aids to remember the characteristics of different respiratory diseases.
