infarction or due to rheumatic fever.
2. What can pericarditis lead to if untreated?
A. Myocardial infarction
B. Atrial fibrillation
C. Cardiac tamponade
D. Stroke
Answer: C
EXPLANATION: Inflammation in the pericardium can result in fluid buildup, compressing the
heart and leading to cardiac tamponade.
3. Which of the following is NOT a common sign of pericarditis?
A. Localized pleuritic chest pain

murmur?
A. Pneumonia
B. Endocarditis

D. Pericarditis
Answer: B

bacterial.
7. What is the gold standard for diagnosing endocarditis?
A. ECG
B. Chest X-ray
C. Transthoracic echocardiogram
