Which explanation will the nurse give a patient with non-Hodgkin lymphoma about the purpose of a planned lumbar puncture?
To rule out any bone marrow involvement.
To determine the level of cell differentiation.
To establish which lymph cell type is involved.
To find any central nervous system involvement.
The Correct Answer is D
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.

Correct Answer is C
Explanation
Choice A rationale:
The sodium level is within the normal range, but the potassium level is slightly elevated. This does not support the rationale for changing the IV prescription to a lower potassium concentration.
Choice B rationale:
The sodium level is slightly elevated, and the potassium level is within the normal range. This does not support the rationale for changing the IV prescription to a lower potassium concentration.
Choice C rationale:
Sodium level of 135 mEq/L, potassium level of 3.6 mEq/L is the correct answer. In this option, both sodium and potassium levels are within normal ranges. Changing the IV prescription to DSNS with 20 mEq KCl/L ensures that the patient receives adequate hydration (from the dextrose and normal saline) without causing hyperkalemia.
Choice D rationale:
The sodium level is slightly elevated, and the potassium level is within the normal range. This does not support the rationale for changing the IV prescription to a lower potassium concentration.
Correct Answer is C
Explanation
Choice A rationale:
Palpating lymph nodes for swelling is not directly related to thrombocytopenia. Thrombocytopenia is a condition characterized by a low platelet count, which can lead to easy bruising and bleeding. Checking lymph nodes is more relevant in assessing for infection or malignancy.
Choice B rationale:
Checking temperature for elevation is important for assessing infection, which could be a cause of thrombocytopenia. However, in this context, inspecting the skin for bruising or petechiae is more specific to thrombocytopenia. Petechiae are small, red or purple dots that appear on the skin when platelet count is low.
Choice D rationale:
Examining oral mucosa for ulceration is essential in the assessment of conditions like oral cancer or infection. While thrombocytopenia could lead to bleeding in the oral mucosa, it is not the most specific or immediate concern in a patient with known thrombocytopenia.
