A nurse is preparing to administer the prescribed vitamin B12 to a client who has had most of his ileum removed. The nurse understands that this is necessary for which reason?
A) Prevents thrombosis
B) Prevents deficiencies
C) Aids proper digestion
D) Prevents constipation
B
Feedback:
Parenteral injections or intranasal administrations (Nascobal) of vitamin B12 are used to prevent deficiencies in clients who have had most or all of the ileum removed because this area is responsible for B12 absorption. Vitamin B12 does not prevent thrombosis or constipation or aid digestion.
