Final answer:
Nausea and vomiting would cause a nurse to suspect dumping syndrome in a client who had a gastric resection with a vagotomy, as it indicates food is moving too quickly from the stomach into the small intestine. The Correct Answer is Option. B.
Step-by-step explanation:
The symptom that would cause a nurse to suspect dumping syndrome in a client who had a gastric resection with a vagotomy is B) Nausea and vomiting.
Dumping syndrome occurs when food moves too quickly from the stomach to the small intestine, which can result in a variety of symptoms, including nausea, vomiting, diarrhea, dizziness, and fatigue.
These symptoms occur because the rapid 'dumping' of stomach contents into the small intestine can lead to sudden fluid shifts in the body and the rapid release of certain hormones.
Options A) Elevated blood pressure, C) Increased appetite, and D) Constipation are not typically associated with dumping syndrome. Instead, these signs might be related to other conditions or complications following surgery.
