The nurse is reinforcing teaching for a patient who had a large portion of the stomach removed
Which of the following conditions, if stated by the patient, would indicate a correct understanding of why there usually is a need to receive vitamin B12 for life?
a. Acquired hemolytic anemia
b. Iron-deficiency anemia
c. Pernicious anemia
d. Sickle cell anemia
ANS: C
Vitamin B12 deficiency can occur after some or all of the stomach is removed because intrinsic factor secretion is reduced or gone. Normally, vitamin B12 combines with intrinsic factor to prevent its digestion in the stomach and promote its absorption in the intestines. Lifelong administration of vitamin B12 is required to prevent the development of pernicious anemia.
