A patient with thalassemia major who is receiving a blood transfusion shows signs of hemochromatosis.
The nurse anticipates a prescription for which medication?
Methotrexate.
Deferoxamine.
Ferrous gluconate.
Iron dextran complex.
The Correct Answer is B
Choice A rationale:
Methotrexate is a medication used for cancer and autoimmune diseases. It does not chelate iron and is not used to treat iron overload conditions like hemochromatosis.
Choice B rationale:
Deferoxamine is an iron chelating agent used to treat iron overload conditions like hemochromatosis. It binds to excess iron and promotes its excretion from the body, preventing complications such as organ damage.
Choice C rationale:
Ferrous gluconate is an iron supplement used to treat iron deficiency anemia. It would not be appropriate for a patient with hemochromatosis, a condition characterized by iron overload.
Choice D rationale:
Iron dextran complex is another form of intravenous iron used to treat iron deficiency anemia. It is not indicated for treating iron overload conditions like hemochromatosis.

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
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.
