A newborn is diagnosed with congenital intrinsic factor deficiency. Which of the following types of anemia will the nurse see documented on the chart?

a. Iron deficiency anemia

b. Pernicious anemia

c. Sideroblastic anemia

d. Hemolytic anemia

b. Pernicious anemia

Explanation:

Pernicious anemia, also called Addison's anemia, is a form of anemia generated from a congenital deficiency of intrinsic factor that causes the body's inability to properly absorb vitamin B12. The result is a reduction in the number of red blood cells in the blood.

Pernicious anemia belongs to the broad group of megaloblastic anemias, which basically consist of vitamin B12 deficiency in the body. Only when malabsorption of this substance occurs through the intestines is the condition called pernicious anemia.
