A client diagnosed with polycythemia is receiving education on self-care.
Which statement by the client indicates a need for further education?
"I should drink at least 3 liters of fluids each day.”
"I should avoid hot baths and showers.”
"I can continue to smoke, but I'll cut down.”
"I need to monitor my vital signs regularly.”
The Correct Answer is C
Choice A rationale:
Drinking an adequate amount of fluids is essential for patients with polycythemia to prevent blood clots and maintain blood flow.
This statement indicates a good understanding of self-care.
Choice B rationale:
Avoiding hot baths and showers is essential because heat can cause vasodilation and further increase blood flow, potentially exacerbating symptoms of polycythemia.
This statement also shows appropriate self-care knowledge.
Choice C rationale:
Smoking is a significant risk factor for polycythemia and other cardiovascular conditions.
Continuing to smoke, even with the intention to cut down, is not advisable and indicates a need for further education.
Smoking cessation is essential for managing polycythemia effectively.
Choice D rationale:
Monitoring vital signs regularly is crucial for patients with polycythemia to detect any changes in blood pressure, heart rate, or oxygen saturation.
This statement demonstrates an understanding of the importance of self-monitoring and is not a cause for further education.

Correct Answer is B
Explanation
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.
Correct Answer is C
Explanation
Choice A rationale:
Dehydration does not cause polycythemia vera.
Polycythemia vera is a disorder of the bone marrow characterized by an overproduction of red blood cells.
Choice B rationale:
Chronic pulmonary disease is not a cause of polycythemia vera.
Polycythemia vera is typically due to a mutation in the JAK2 gene.
Choice C rationale:
This is the correct answer.
Polycythemia vera is often caused by a mutation in the JAK2 gene, which leads to an abnormal increase in red blood cell production.
Choice D rationale:
Smoking can lead to secondary polycythemia, but it is not the cause of polycythemia vera, which is a primary disorder of the bone marrow.
