Advanced Patient Assessment Practice Exam

In a patient's chart, the physician has documented finding tender lymph nodes in the neck region during the physical examination. This problem is consistent with:

1. Lung cancer

2. Respiratory infection

3. Human immunodeficiency virus (HIV) infection

4. Lymphoma

The correct answer is: Respiratory infection

Tender lymph nodes in the neck region are most commonly associated with a respiratory infection, such as viral or bacterial infections that cause inflammation in the throat or upper respiratory tract. Lymph nodes often swell and become tender as they work to fight off infection, indicating that the immune system is responding to a pathogen. In the context of respiratory infections, conditions like pharyngitis, tonsillitis, or sinusitis may lead to this finding. The lymphatic system reacts by becoming active in producing lymphocytes, which can result in enlarged, tender lymph nodes in nearby regions, such as the neck. Other conditions listed, like lung cancer and lymphoma, can present with lymphadenopathy, but they typically do not lead to the same sudden tenderness associated with infection. HIV infection can also lead to lymph node enlargement, but this is more often characterized by generalized lymphadenopathy rather than localized tenderness in the acute setting. Therefore, the presence of tender lymph nodes in the neck is most consistent with a respiratory infection.
