Which explanation will the nurse give a patient with non-Hodgkin lymphoma about the purpose of a planned lumbar puncture?

Choice A rationale:

Enteric-coated iron is designed to be absorbed in the small intestine, not the stomach. Taking it with each meal might decrease its absorption due to interaction with food.

Choice B rationale:

Cobalamin (vitamin B12) deficiency can cause macrocytic anemia, not microcytic hypochromic anemia. Taking cobalamin with green, leafy vegetables does not address the specific iron deficiency seen in microcytic hypochromic anemia.

Choice C rationale:

Take the iron with orange juice 1 hour before meals is the correct answer. Vitamin C enhances the absorption of non-heme iron (the type of iron found in plant-based foods and iron supplements) by reducing it to a more absorbable form. Taking iron supplements with orange juice, which is high in vitamin C, can significantly improve iron absorption. Taking it before meals ensures better absorption due to reduced interaction with other dietary components.

Choice D rationale:

Decreasing the intake of antiseizure medications will not improve microcytic hypochromic anemia. Antiseizure medications do not directly influence iron absorption or the production of red blood cells.

The correct answer is c. Respiratory acidosis.

Choice A reason: Metabolic acidosis is incorrect because the HCO3 level is normal. In metabolic acidosis, we would expect to see a decreased HCO3.

Choice B reason: Metabolic alkalosis is incorrect because the HCO3 level is normal. In metabolic alkalosis, we would expect to see an increased HCO3.

Choice C reason: The given ABG results indicate a low pH (acidosis), an elevated PaCO2 (respiratory component), and a normal HCO3 (metabolic component). The low pH and increased PaCO2 suggest respiratory acidosis.

Choice D reason: Respiratory alkalosis is incorrect because the PaCO2 level is elevated, not decreased. In respiratory alkalosis, we would expect to see a decreased PaCO2.
