The nurse is taking a medication history on a newly admitted patient. The patient reports taking folic acid and vitamin B12 . The nurse notifies the provider because of the concern that folic acid can:
a. cause fetal malformation.
b. mask the signs of vitamin B12 deficiency.
c. negatively affect potassium levels.
d. worsen megaloblastic anemia.
B
Folic acid can reverse the hematologic effects of vitamin B12 deficiency, but it does not reverse the neurologic effects, so it is important to determine the degree of B12 deficiency to treat it. Fol-ic acid does not cause fetal malformation; in fact, it can help prevent neural tube defects. Folic acid does not worsen megaloblastic anemia. Folic acid does not affect potassium levels.
