A nurse is caring for a client who is taking ferrous sulfate to treat iron deficiency anemia and develops iron toxicity. Which of the following drugs should the nurse expect to use to treat this complication?

Correct Answer: D

Rationale: The correct answer is D: Deferoxamine. Deferoxamine is an iron chelator that binds to excess iron in the body and helps facilitate its excretion. In cases of iron toxicity, Deferoxamine is the treatment of choice as it helps remove the excess iron from the body. A: Flumazenil is a benzodiazepine receptor antagonist used to reverse benzodiazepine overdose. B: Acetylcysteine is used to treat acetaminophen overdose by replenishing glutathione stores. C: Naloxone is an opioid receptor antagonist used to reverse opioid overdose. In summary, the other choices are incorrect because they are used to treat overdoses of benzodiazepines, acetaminophen, and opioids respectively, not iron toxicity.

Correct Answer: B

Rationale: The correct answer is B: Palmer pallor. This is because pallor, especially on the palms (Palmer pallor), is a common sign of anemia due to the decreased amount of hemoglobin in the blood, leading to reduced oxygen-carrying capacity. Insomnia (A) is not specifically associated with anemia. Fever (C) is not a typical symptom of anemia unless it is due to an underlying infection or inflammatory condition. Angina (D) is chest pain caused by reduced blood flow to the heart, not a direct sign of anemia. In summary, Palmer pallor is the most relevant sign to indicate anemia, while the other choices are not directly related to this condition.

Correct Answer: B

Rationale: The correct answer is B: Stuart Prower factor, also known as Factor X. This coagulation factor is dependent on vitamin K for its synthesis. Vitamin K is essential for the post-translational modification of certain coagulation factors, including Factor X. Thromboplastin (A) is not a coagulation factor, but rather a tissue factor involved in the initiation of coagulation. Hageman factor (C) is Factor XII, which is not vitamin K-dependent. Proaccelerin (D) is also known as Factor V and is not vitamin K-dependent. In summary, only Stuart Prower factor (Factor X) is a vitamin K-dependent coagulation factor among the choices provided.

Correct Answer: A

Rationale: The correct answer is A: Jaundice. Jaundice is a yellowing of the skin and eyes due to an excess of bilirubin, a byproduct of red blood cell breakdown. In this case, rapid destruction of red blood cells leads to an increased production of bilirubin, causing jaundice. Bleeding (B) is not directly related to red blood cell destruction. Diarrhea (C) and cyanosis (D) are not typically associated with red blood cell destruction.

Correct Answer: A

Rationale: The correct answer is A: Observe for bleeding. After a bone marrow biopsy, the most important nursing action is to monitor for bleeding, as the patient is at risk for hemorrhage due to the invasive nature of the procedure. Observing for bleeding includes assessing the dressing, vital signs, and the puncture site for any signs of hematoma or excessive bleeding. Encouraging oral fluids (B) helps prevent dehydration but is not the most critical post-biopsy action. Administering an analgesic (C) for pain is important for patient comfort but does not address the immediate risk of bleeding. Monitoring for infection (D) is important but is not the priority immediately following the biopsy.
