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.

Choice A rationale:

A lumbar puncture is not typically performed to rule out bone marrow involvement in non-Hodgkin lymphoma. Imaging studies and bone marrow biopsies are more appropriate for evaluating bone marrow involvement.

Choice B rationale:

Determining the level of cell differentiation is not the primary purpose of a lumbar puncture in non-Hodgkin lymphoma. This information is usually obtained from a biopsy of the affected lymph nodes or organs.

Choice C rationale:

Identifying the specific lymph cell type involved is not the main objective of a lumbar puncture in non-Hodgkin lymphoma. This information is usually determined through lymph node biopsy and other imaging studies.

Choice D rationale:

The purpose of a lumbar puncture in non-Hodgkin lymphoma is to find any central nervous system involvement. Lymphoma cells can spread to the central nervous system, and a lumbar puncture allows for the examination of cerebrospinal fluid to detect any cancerous cells, which can guide treatment decisions.

Choice A rationale:

Anemia is not a direct manifestation of target organ damage from hypertension.

Choice B rationale:

Aneurysm is a correct answer. Persistent high blood pressure can weaken the walls of arteries, making them more susceptible to forming an aneurysm. Aneurysms can occur in various arteries, such as the aorta, and can lead to life-threatening complications if they rupture.

Choice C rationale:

Proteinuria is also a correct answer. Hypertension can damage the kidneys, leading to proteinuria, the presence of excess proteins in the urine. This is an indication of kidney damage and is a common manifestation of hypertensive target organ disease.

Choice D rationale:

Pneumonia and Transient Ischemic Attack (TIA) are not direct manifestations of target organ damage from hypertension.
