A nurse is teaching a client who has a new diagnosis of hemolytic anemia. Which of the following information should the nurse include in the teaching?
Hemolytic anemia results in an increased rate of RBC destruction.

Hemolytic anemia is associated with a decreased intake of iron.
Hemolytic anemia results in an inability to absorb vitamin B12.

B. Decreased RBC production is more characteristic of aplastic anemia or anemia of chronic disease.
C. Iron deficiency anemia, not hemolytic anemia, results from decreased iron intake.

Correct Answer is D
Explanation
A. Vitamin B6 is important for overall health but does not treat pernicious anemia.
B. Increasing dietary intake of B12-rich foods like red meat and liver is ineffective since the body cannot absorb B12 due to intrinsic factor deficiency.
C. While some anemias affect bone marrow function, pernicious anemia is not associated with increased infection and bleeding risk.
D. Pernicious anemia is caused by a lack of intrinsic factor, which is necessary for vitamin B12 absorption. Since dietary B12 cannot be absorbed, lifelong vitamin B12 injections are required.
