A 52-year-old patient has a new diagnosis of pernicious anemia. The nurse determines that the patient understands the teaching about the disorder when the patient states, "I
a. need to start eating more red meat and liver."
b. will stop having a glass of wine with dinner."
c. could choose nasal spray rather than injections of vitamin B12."
d. will need to take a proton pump inhibitor like omeprazole (Prilosec)."
ANS: C
Because pernicious anemia prevents the absorption of vitamin B12, this patient requires injections or intranasal administration of cobalamin. Alcohol use does not cause cobalamin deficiency. Proton pump inhibitors decrease the absorption of vitamin B12. Eating more foods rich in vitamin B12 is not helpful because the lack of intrinsic factor prevents absorption of the vitamin.
