The nurse suspects that a patient has polycythemia vera based on which finding in the patient's laboratory reports? Select all that apply.
One, some, or all responses may be correct.
Increased cobalamin levels.
Decreased histamine levels.
Increased hemoglobin levels.
Increased red blood cell levels.
Correct Answer : C,D
Choice A rationale:
Increased cobalamin levels are not indicative of polycythemia vera. Polycythemia vera is characterized by an increase in the total red blood cell mass. Elevated cobalamin levels are not specific to this condition.
Choice B rationale:
Decreased histamine levels are not a diagnostic marker for polycythemia vera. Histamine levels are not typically associated with this disorder.
Choice C rationale:
Increased hemoglobin levels are a significant finding in polycythemia vera. Polycythemia vera is a disorder characterized by an abnormal increase in the number of red blood cells, leading to elevated hemoglobin levels.
Choice D rationale:
Increased red blood cell levels are a hallmark feature of polycythemia vera. The increased production of red blood cells leads to elevated red blood cell levels, which is a key diagnostic indicator for this condition.

Correct Answer is C
Explanation
The correct answer is choice C. Uses an alcohol-based mouthwash twice a day.
Choice A rationale:
Drinking 14 glasses of water daily is generally beneficial as it helps maintain hydration and supports overall health. However, it is important to balance fluid intake to avoid overhydration.
Choice B rationale:
Shaving with an electric razor is recommended for patients with thrombocytopenia because it reduces the risk of cuts and bleeding compared to using a traditional razor.
Choice C rationale:
Using an alcohol-based mouthwash can cause dryness and irritation of the oral mucosa, which can lead to bleeding, especially in patients with thrombocytopenia. It is better to use a non-alcoholic mouthwash.
Choice D rationale:
Brushing teeth with a soft-bristle toothbrush is advised to minimize the risk of gum bleeding and maintain oral hygiene.
Correct Answer is D
Explanation
Choice A rationale:
Stenosis of the heart valves typically leads to murmurs and changes in heart sounds but does not directly impact blood pressure regulation.
Choice B rationale:
Decreased adrenergic sensitivity might lead to lower heart rate and blood pressure, not an increase in systolic blood pressure as seen in this case.
Choice C rationale:
Increased parasympathetic activity would lead to decreased heart rate, not an increase in systolic blood pressure as observed in the patient.
Choice D rationale:
Loss of elasticity in arterial vessels is the correct answer. With aging, arterial walls become less flexible and more rigid due to the accumulation of calcium and collagen. This loss of elasticity results in increased systolic blood pressure, which is the top number in a blood pressure reading. The diastolic pressure, represented by the bottom number, does not usually increase significantly with age. This change is a result of arteriosclerosis, which commonly occurs in elderly individuals.
