A nurse palpates a client's cervical lymph nodes and notes the following findings: cervical lymph nodes 0.6 inches (1.5 cm) in diameter, painful, and mobile. What is the best action of the nurse?

Cervical lymphadenopathy reflects activation of the immune system, typically due to infectious processes, inflammatory conditions, or less commonly malignancy, resulting in lymph node enlargement, tenderness, and mobility depending on etiology and stage of immune response activation within lymphatic tissue structures. Rationale: A. Asking about a history of cancer may be premature without additional assessment data. Although malignancy can cause lymphadenopathy, painful and mobile nodes more commonly indicate infection. Focus should first be on associated systemic or infectious symptoms before considering oncologic history. B. These findings are not normal because lymph node enlargement &ge; 1 cm, tenderness, and increased size indicate active immune response. Normal lymph nodes are typically < 1 cm, non-tender, and non-palpable. Therefore, documentation as normal would be clinically inaccurate assessment interpretation. C. Notifying the health care provider is not the immediate action because further assessment is required first. Painful, mobile lymph nodes suggest infection rather than urgent malignancy. Additional symptom evaluation helps determine etiology before escalation or diagnostic workup is initiated clinically. D. Asking about additional systemic symptoms such as fever, sore throat, fatigue, or recent infection provides essential diagnostic context. Cervical lymphadenopathy is often reactive. Comprehensive symptom assessment guides differentiation between infectious, inflammatory, or malignant causes before further clinical action or escalation decisions.
