Which of the following is NOT considered a lower respiratory tract infection?

• A. Pneumonia
• B. Tuberculosis
• C. Pharyngitis
• D. Bronchitis

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the anatomy of the respiratory tract by dividing it into the upper and lower respiratory tracts. The upper respiratory tract includes the nose, nasal cavity, pharynx, and larynx, while the lower respiratory tract includes the trachea, bronchi, bronchioles, and lungs.
2. Step 2: Identify the infections listed and determine which part of the respiratory tract they primarily affect. Pneumonia affects the lungs, Tuberculosis primarily affects the lungs, and Bronchitis affects the bronchi, all of which are part of the lower respiratory tract.
3. Step 3: Recognize that Pharyngitis is an infection of the pharynx, which is part of the upper respiratory tract, not the lower respiratory tract.
4. Step 4: Conclude that since Pharyngitis affects the upper respiratory tract, it is NOT considered a lower respiratory tract infection, unlike the other options.
5. Step 5: Summarize that the key to solving this problem is knowing the anatomical divisions of the respiratory system and associating each infection with its correct location.
