An adult client comes to the clinic and reports concern over a lump that, "Just popped up on my neck about a week ago." While performing an examination of the lump, the nurse palpates a large, nontender, hardened left subclavian lymph node. There is no overlying tissue inflammation. Which of these findings suggest?

A. Lymphangitis is characterized by inflammation of the lymphatic vessels and is often associated with red streaks and tenderness. The absence of inflammation and tenderness suggests a different etiology. B. Malignancy is suggested by the presence of a large, nontender, hardened lymph node. These characteristics are commonly associated with metastatic spread of cancer to the lymph nodes. Further diagnostic testing, such as biopsy, would be warranted to confirm malignancy. C. Viral infection may cause lymphadenopathy, but typically, the lymph nodes are tender and may be enlarged but not necessarily hardened. The absence of tenderness and the hardened consistency of the lymph node suggest a different etiology. D. Bacterial infection can cause lymphadenopathy, which may be tender and enlarged, but the nontender, hardened nature of the lymph node in this case is more indicative of malignancy rather than a bacterial infection.
