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 D
Explanation
Choice A rationale:
Taking a daily walk is a beneficial activity for patients with venous leg ulcers. Walking promotes blood circulation, which can aid in wound healing. This statement indicates that the patient understands the importance of physical activity for their condition.
Choice B rationale:
Trying to lose weight is another positive step for a patient with venous leg ulcers, especially if the patient is overweight. Excess body weight can put additional pressure on the veins in the legs, worsening venous insufficiency. Losing weight can alleviate this pressure and improve venous circulation, supporting the healing process of leg ulcers.
Choice C rationale:
Wearing stockings after getting out of bed is a proper technique for managing venous leg ulcers. Compression stockings help improve blood flow in the legs and reduce swelling, which is beneficial for patients with venous insufficiency and leg ulcers. This statement indicates that the patient understands the importance of wearing compression stockings consistently.
Choice D rationale:
Not wearing knee-high socks that are tight around the calf is essential advice for patients with venous leg ulcers. Tight clothing, including socks or stockings, can impede blood circulation in the legs, worsening venous insufficiency and delaying wound healing. This statement indicates the need for further education because the patient should avoid any tight clothing around the affected area to promote optimal blood flow and wound healing.
Correct Answer is C
Explanation
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.
