38
Q

What would be expected with multiple myeloma?

A

Anemia

39
Q

Why are kidney issues frequently seen in patients with multiple myeloma?

Q

Why might the presence of BCR-ABL in a leukemia patient be a positive thing?

A

BCR-ABL is a target for some leukemia therapies

45
Q

Why is subtyping of AML more often performed that subtyping of CML or CLL?

Aortic pressure and ventricular pressure become disconnected because?

A
57
Q

This is the most common valvular abnormality.

64
Q

Mitral valve stenosis causes increased pressure in the?

A

Left atrium

65
Q

Pressure backup from this valvular insufficiency causes atrial fibrillation in the neck and ascites.
