Question

a 69-year-old male patient presents with low back pain, fatigue, and 20 lbs of weight loss over the last month. lab work reveals ssa+2 and rouleaux formation. which of the following lab markers would you also expect to find?
yellow foam in the urine
jaundice
white foam in the urine
increased esr
hematuria

Explanation:

The patient's symptoms (low back pain, fatigue, weight loss) and lab findings (SSA + 2, rouleaux formation) suggest a condition like multiple myeloma or a plasma cell disorder. Increased ESR (erythrocyte sedimentation rate) is common in such disorders due to abnormal proteins affecting red blood cell aggregation, which aligns with rouleaux formation. Yellow/white foam in urine and jaundice are not typical here, and hematuria is not directly linked to these lab findings.

Answer:

Increased ESR
