Which condition is a cause of an acquired murmur?

A. Fever: Fever is a common sign of pericarditis, often indicating inflammation or infection in the pericardial sac. This symptom is typical in patients with this condition.

B. Mild chest pain: Mild chest pain is a typical symptom of pericarditis. Patients often experience sharp, pleuritic chest pain that may worsen with inspiration or coughing.

C. No evidence of fatigue: Fatigue can be a common symptom in patients with pericarditis due to the body's response to inflammation. Therefore, the absence of fatigue is not typical, making this an appropriate choice.

D. Myalgias: Myalgias or muscle aches can occur in pericarditis as part of the systemic inflammatory response. This symptom is not unusual in patients with this condition.

E. Pericardial friction rub: A pericardial friction rub is a characteristic finding in pericarditis, heard during auscultation. It results from the movement of inflamed pericardial layers against each other.

F. Radiating substernal pain felt in the left shoulder: This type of radiating pain is more characteristic of myocardial ischemia or angina rather than pericarditis. While pericarditis can cause chest pain, it does not typically radiate in the same manner as that seen in cardiac conditions, making this an appropriate choice.

A. Chest pain: While chest pain can occur in various pulmonary diseases, it is not as universally common or characteristic as cough. Chest pain may be more indicative of specific conditions rather than a broad symptom associated with pulmonary disease.

B. Cough: Cough is one of the most common symptoms associated with pulmonary disease, often occurring in conditions such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and bronchitis. It serves as a protective reflex to clear airways and is frequently reported by patients with pulmonary issues.

C. Hemoptysis: Hemoptysis, or coughing up blood, can be a significant symptom in certain pulmonary conditions (e.g., lung cancer, pulmonary embolism), but it is not as common across all pulmonary diseases. It is typically more specific to particular conditions.

D. Digit clubbing: Digit clubbing is a physical finding associated with chronic pulmonary diseases, particularly those that cause long-term hypoxia (e.g., cystic fibrosis, interstitial lung disease). However, it is less common than cough and typically develops over time rather than being a frequent presenting symptom.
