Final answer:
Vitamin B12 injections to prevent pernicious anemia are most likely included in the medication regimen for a patient with inflammatory bowel disease.
Step-by-step explanation:
Inflammatory bowel disease (IBD) can require hospital treatment, and medication regimens depend on the specific condition and symptoms of the patient. While anticholinergic medications and antiemetics may help manage some symptoms, they may not be the most likely options for this patient. However, vitamin B12 injections are often included in the medication regimen for patients with IBD to prevent pernicious anemia. Beta-adrenergic blockers, on the other hand, are not typically used to reduce bowel motility in patients with IBD.
