The nurse presents information to a group of nursing students about cultural and ethnic health disparities related to hypertension.
Which information would the nurse include about the comparison of Mexican Americans to White and Black populations?

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.

The correct answer is Choice D. Then start with Choice A rationale:

Choice A is incorrect because it representsmetabolic alkalosis, not respiratory alkalosis. Metabolic alkalosis occurs when there is a primary increase in the bicarbonate (HCO3) level, which causes the pH to rise above the normal range (7.35-7.45). The PaCO2 is normal in this case, indicating that the respiratory system is not involved in the acid-base imbalance.Some causes of metabolic alkalosis include vomiting, diuretic use, excessive antacid intake, and mineralocorticoid excess1.

Choice B is incorrect because it representsrespiratory acidosis, not respiratory alkalosis. Respiratory acidosis occurs when there is a primary decrease in the PaCO2 level, which causes the pH to fall below the normal range. The HCO3 is normal in this case, indicating that the metabolic system is not involved in the acid-base imbalance.Some causes of respiratory acidosis include hypoventilation, airway obstruction, chest trauma, neuromuscular disorders, and chronic lung diseases2.

Choice C is incorrect because it representsmetabolic acidosis, not respiratory alkalosis. Metabolic acidosis occurs when there is a primary decrease in the HCO3 level, which causes the pH to fall below the normal range. The PaCO2 is normal in this case, indicating that the respiratory system is not involved in the acid-base imbalance.Some causes of metabolic acidosis include diabetic ketoacidosis, lactic acidosis, renal failure, diarrhea, and poisoning3.

Choice D is correct because it representsrespiratory alkalosis. Respiratory alkalosis occurs when there is a primary decrease in the PaCO2 level, which causes the pH to rise above the normal range. The HCO3 is normal in this case, indicating that the metabolic system is not involved in the acid-base imbalance. Some causes of respiratory alkalosis include hyperventilation, anxiety, panic, fever, pain, tumor, trauma, severe anemia, liver disease, overdose of certain medicines, pulmonary embolism, pregnancy, and any lung disease that leads to shortness of breath . Respiratory alkalosis is characterized by symptoms such as breathlessness, dizziness, numbness, tingling, muscle spasms, chest discomfort, confusion, and fainting.
