A) "Lack of vitamin K causes pernicious anemia."
B) "Lack of vitamin B12 causes pernicious anemia."
C) "Lack of amino acids causes pernicious anemia."
D) "Lack of starch molecules causes pernicious anemia."
B
Feedback:
The nurse should inform the client that lack of vitamin B12 leads to pernicious anemia. Lack of intrinsic factor results in the inability of the body to absorb vitamin B12 . Lack of vitamin K, amino acids, and starch molecules do not cause pernicious anemia.
