Answer to Question 1
Correct Answer: 2
Rationale 1: Iron-deficiency anemia is due to lack of iron in the diet or to iron loss as a result of chronic bleeding. Vitamin B12 would not correct this condition.
Rationale 2: Injections of cyanocobalamin (vitamin B12) are administered to clients with pernicious anemia.
Rationale 3: Vitamin B12 is not effective in treating sickle-cell anemia, which is a blood disorder characterized by red blood cells that assume an abnormal, rigid, sickle shape.
Rationale 4: Aplastic anemia is a condition in which bone marrow does not produce sufficient new cells to replenish blood cells. Vitamin B12 would not be effective in treating this type of anemia.
Global Rationale: Cyanocobalamin is used to treat vitamin B12 deficiency and anemia due to malabsorption syndrome, such as in pernicious anemia; sprue; GI pathology, dysfunction, or surgery; fish tapeworm infestation; and gluten enteropathy. It is not an effective treatment for iron deficiency anemia, sickle-cell anemia, or aplastic anemia.
