The patient presents with fever for the last few days, sore throat and enlarged lymph nodes under the jaw. What is the appropriate response of the nurse when the patient asks about the cause of the enlarged lymph nodes?

A. Enlarged lymph nodes are associated with hypertensive heart disease is not a correct association. Hypertension does not directly cause lymph node enlargement. B. They are most likely enlarged as a result of the throat infection is the correct answer. Enlarged lymph nodes, especially under the jaw, are commonly seen in response to infections, particularly in the throat (such as a viral or bacterial infection like pharyngitis). C. You should probably see an oncologist to rule out lymphedema is an unnecessary response at this time. Lymphedema usually presents with other symptoms, and the patient's symptoms (fever, sore throat, and localized lymph node enlargement) suggest an infection rather than cancer. D. You probably have a blockage in the thoracic lymph duct is not a common cause of localized lymph node enlargement. Blockages in the thoracic duct would affect lymphatic flow more generally and would present with more systemic symptoms.
