The nurse devises a teaching plan for the patient with aplastic anemia. Which of the following is the most important concept to teach for health maintenance?

Correct Answer: B

Rationale: Correct Answer: B - Avoid exposure to others with acute infection Rationale: 1. Patients with aplastic anemia have compromised immune systems. 2. Acute infections can be life-threatening for these patients. 3. Teaching the patient to avoid exposure to infections is crucial for preventing complications. 4. This concept directly relates to health maintenance by reducing the risk of infections. Summary: - Choice A: Nutrition is important but not the most critical for aplastic anemia patients. - Choice C: While stress management is beneficial, infection prevention is more vital for health maintenance. - Choice D: Sleep is essential, but avoiding infections takes precedence for aplastic anemia patients.

Correct Answer: B

Rationale: The correct answer is B (4.6-6.0) because it represents the normal range for total Red Blood Cell (RBC) count in men, typically measured in millions per microliter. RBC count outside this range may indicate anemia or other health issues. Choice A (4.0-5.0) is too narrow and may miss slightly elevated RBC levels. Choice C (4.2-6.5) is too wide and includes values above the normal range. Choice D (4.0-6.0) is broader and includes lower values not typically seen in healthy men.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Hydroxyurea inhibits ribonucleotide reductase, leading to decreased DNA synthesis. 2. This action is used in treating conditions like sickle cell anemia, where inhibiting DNA synthesis decreases RBC production. 3. Choice A is incorrect as hydroxyurea actually increases nitric oxide levels. 4. Choice B is incorrect as hydroxyurea decreases WBC production, including neutrophils and monocytes. 5. Choice D is incorrect as hydroxyurea does not increase RBC lifespan but instead decreases RBC production.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Aplastic anemia is a rare disorder characterized by bone marrow failure. 2. While some drugs can cause bone marrow suppression, the mentioned drugs are not typically associated with aplastic anemia. 3. Lithium is linked to neutropenia, acetazolamide to aplastic anemia in rare cases, and aspirin to thrombocytopenia, not aplastic anemia. 4. Therefore, the correct answer is B: FALSE. Summary: - Choice A is incorrect because the drugs listed do not commonly induce aplastic anemia. - Choice C is incorrect as there is limited evidence supporting these drugs as common causes. - Choice D is incorrect as aplastic anemia induced by these drugs is not considered rare.

Correct Answer: B

Rationale: The correct answer is B: Chemotherapy. In Rai stage II of chronic lymphocytic leukemia (CLL), chemotherapy is the conventional treatment to reduce cancer cells and prevent progression. Antibiotics (choice A) are not the primary treatment for CLL. Antivirals (choice C) are used for viral infections, not CLL. Rest (choice D) alone is not sufficient to treat CLL and may lead to disease progression. Chemotherapy targets cancer cells, making it the appropriate treatment for Rai stage II CLL.
