MRCP2-2512

A 67-year-old male patient complains of blurred vision and anemia, with a hemoglobin level of 89 g/L. A total protein test reveals an elevated globulin fraction. Further testing shows an IgM paraprotein level of 37 g/L, and a bone marrow aspirate reveals a lymphoplasmacytic infiltrate. What would be the most crucial investigation to conduct next?

MRCP2-2513

A 49-year-old female with colorectal cancer (Duke’s C) on chemotherapy presents with an acutely painful swollen left leg. She reports that the swelling has been increasing for the past twelve hours and she can see new veins on her calf that were not there before. She has a history of deep vein thrombosis (DVT) and feels that this is similar.
