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.

Answer and Explanation

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 ["B","D"]

Explanation

Choice A rationale:

Palpitations are not directly related to a low hemoglobin level. They can occur due to various cardiac conditions but are not specific to anemia.

Choice B rationale:

Conjunctival pallor is a common physical finding in patients with low hemoglobin levels (anemia) Anemia leads to reduced oxygen-carrying capacity, causing paleness in mucous membranes such as the conjunctiva.

Choice C rationale:

Sternal tenderness is not a typical finding associated with low hemoglobin levels. It is more often associated with conditions affecting the sternum or adjacent structures, such as infections or inflammation.

Choice D rationale:

A heart rate of 104 beats/min can be a compensatory response to anemia. When the body senses reduced oxygen levels due to anemia, the heart rate may increase to pump more blood and oxygen to vital organs, attempting to compensate for the low hemoglobin levels.

A. Does not interact with acids. B. Promotes the excretion of acid. C. Activates the system of acid-base balance. D. Increases the action of the hydrogen ions.

Correct Answer is B

Explanation

Choice A rationale:

The base does interact with acids in the acid-base balance. Bases, by definition, are substances that can accept hydrogen ions (protons) and neutralize acids. In the context of acid-base balance, bases help regulate the pH of body fluids by counteracting the effects of acids.

Choice B rationale:

The role of the base in the acid-base balance is to promote the excretion of acid. Bicarbonate ions (HCO3-) are a vital component of the body's buffering system, helping to neutralize excess acid. The kidneys play a crucial role in excreting acids from the body, maintaining the acid-base balance.

Choice C rationale:

The base does not activate the system of acid-base balance; instead, it is part of the body's natural buffering system. The acid-base balance is regulated by the lungs and kidneys, which work together to maintain the pH of body fluids within a narrow range (7.35-7.45)

Choice D rationale:

Bases do not increase the action of hydrogen ions. In fact, bases neutralize hydrogen ions, which are acidic. By accepting these ions, bases help to decrease the acidity of a solution, playing a key role in maintaining the body's acid-base balance.
