Correct Answer is C

Explanation

Choice A reason: Large, bulky stools are not uncommon after a barium enema, as the barium can cause temporary changes in stool consistency and volume. This finding would not necessarily warrant immediate reporting to the healthcare provider unless there are other concerning symptoms.

Choice B reason: Three formed stools in eight hours may indicate increased bowel activity but is not an unusual finding after a barium enema. This would not typically be a cause for concern unless accompanied by other symptoms.

Choice C reason: Streaks of blood present in the stool is a concerning finding that should be reported to the healthcare provider. The presence of blood may indicate mucosal injury, inflammation, or other complications that need to be addressed promptly.

A. Ondansetron on a PRN basis B. Vitamin B12 injections to prevent pernicious anemia C. Antidiarrheal medications 30 minutes before a meal D. Beta adrenergic blockers to reduce bowel motility

Correct Answer is A

Explanation

Choice A reason:

Ondansetron on a PRN basis is used to manage nausea and vomiting. In patients with inflammatory bowel disease, especially during an inpatient stay, controlling nausea is important to maintain comfort and prevent dehydration. This makes it an appropriate symptomatic treatment.

Choice B reason:

Vitamin B12 injections may be indicated in patients with Crohn’s disease who have malabsorption issues, particularly if the terminal ileum is involved. However, they are not routinely given to all patients with inflammatory bowel disease solely for the prevention of pernicious anemia.

Choice C reason:

Antidiarrheal medications are generally contraindicated in inflammatory bowel disease, as they can mask important symptoms and may increase the risk of complications like toxic megacolon, especially if administered before meals.

Choice D reason:

Beta adrenergic blockers are not used to reduce bowel motility. Their primary use is in cardiovascular conditions, and they do not address the gastrointestinal symptoms associated with inflammatory bowel disease.
