Lyme disease is characterized by which features?

• A. Bulls-eye rash with flu-like symptoms and potential AV block if untreated
• B. Productive cough with green sputum
• C. Severe abdominal pain after meals
• D. Skin dryness with itching

Answer: (A)

The features tested are the classic signs of early Lyme disease. The bull's-eye rash, known as erythema migrans, combined with flu-like symptoms such as fever, fatigue, and malaise, points to Borrelia burgdorferi infection. If this infection isn’t treated, it can affect the heart’s conduction system, leading to atrioventricular (AV) block, which explains the potential heart involvement described. This combination—rash with systemic symptoms and possible cardiac involvement—best fits Lyme disease. The other options describe signs more typical of respiratory infection (productive cough with green sputum), abdominal GI issues after meals, or skin itching without the migratory rash pattern, so they don’t match Lyme disease.
