question 85
jacob reports a neck mass that has been present intermittently for 5 or 6 weeks which varies in size. the provider palpates a lymph node measuring 1.25 cm. which test will provide proper histologic diagnosis for this patient?
bone marrow aspirate
computed tomography (ct) scan with intravenous (iv) contrast
lymph node biopsy
positron emission tomography (pet) scan

Explanation:

A lymph node biopsy is the gold - standard for obtaining a histologic diagnosis of a lymph node. A bone marrow aspirate is more relevant for disorders of the bone marrow (e.g., leukemia). A CT scan with IV contrast provides anatomical details but not histology. A PET scan shows metabolic activity but also does not give a histologic diagnosis.

Answer:

Lymph node biopsy
