Polycythemia
Polycythemia ( 15 Questions)
A client with polycythemia is undergoing additional tests to rule out secondary causes.
Which diagnostic test is commonly used to rule out secondary polycythemia?
A renal ultrasound is not commonly used to rule out secondary polycythemia. Polycythemia is primarily related to an increase in red blood cell production, and renal ultrasound is used to assess kidney function and anatomy, which is not directly related to the cause of polycythemia.
A bone marrow biopsy is commonly used to rule out secondary polycythemia. Polycythemia can be primary (due to a problem within the bone marrow itself) or secondary (due to external factors like hypoxia or tumors) A bone marrow biopsy can help differentiate between primary and secondary causes by examining the bone marrow's production of red blood cells.
A chest x-ray may be ordered to evaluate the lungs and chest, but it is not the primary diagnostic test used to rule out secondary polycythemia. It may help identify lung conditions that contribute to hypoxia, which can lead to secondary polycythemia, but it does not directly assess the bone marrow or red blood cell production.
Thyroid function tests are not typically used to rule out secondary polycythemia. Thyroid function tests assess the thyroid gland's hormone production and are unrelated to the primary causes of polycythemia.
Choice A rationale:
A renal ultrasound is not commonly used to rule out secondary polycythemia.
Polycythemia is primarily related to an increase in red blood cell production, and renal ultrasound is used to assess kidney function and anatomy, which is not directly related to the cause of polycythemia.
Choice B rationale:
A bone marrow biopsy is commonly used to rule out secondary polycythemia.
Polycythemia can be primary (due to a problem within the bone marrow itself) or secondary (due to external factors like hypoxia or tumors)
A bone marrow biopsy can help differentiate between primary and secondary causes by examining the bone marrow's production of red blood cells.
Choice C rationale:
A chest x-ray may be ordered to evaluate the lungs and chest, but it is not the primary diagnostic test used to rule out secondary polycythemia.
It may help identify lung conditions that contribute to hypoxia, which can lead to secondary polycythemia, but it does not directly assess the bone marrow or red blood cell production.
Choice D rationale:
Thyroid function tests are not typically used to rule out secondary polycythemia.
Thyroid function tests assess the thyroid gland's hormone production and are unrelated to the primary causes of polycythemia.
