In assessing a patient with polycythemia vera, which finding would the nurse anticipate?

• A. Pale complexion
• B. Low blood pressure
• C. High hemoglobin
• D. Normal energy level

Answer: (C)

Polycythemia vera causes an increase in red blood cell mass, which raises hemoglobin and hematocrit levels and makes the blood thicker (hyperviscous). This higher hemoglobin reflects the overproduction of red cells, a hallmark of the disorder. The thickened blood can lead to vascular symptoms like headaches, dizziness, and a ruddy, plethoric complexion due to increased red cells. So, the nurse would expect a high hemoglobin value.

Pale skin would suggest anemia, not polycythemia. Low blood pressure is not a characteristic finding of PV, and patients may actually have normal or elevated blood pressure rather than consistently low. Normal energy level isn’t typical because hyperviscosity can cause fatigue and other symptoms.
