ONCC Oncology Certified Nurse (OCN) - Exam Topics Sample Questions

Which gastrointestinal condition presents with symptoms of dehydration and succusion splash?

Correct Answer:
pyloric obstruction


the correct answer to the question is "pyloric obstruction." pyloric obstruction, also known as gastric outlet obstruction, is a condition where the passage from the stomach to the small intestine (the pylorus) is blocked either partially or completely. this obstruction can result from various causes including peptic ulcers, pyloric stenosis, or malignancies that affect the area.

symptoms of pyloric obstruction include severe abdominal pain, vomiting, and a notable delay in gastric emptying. vomiting often leads to dehydration, as the body loses significant amounts of fluids and electrolytes. this dehydration is a critical symptom and can be severe depending on the frequency and volume of vomiting.

another characteristic symptom of pyloric obstruction is a succussion splash. this can be heard during a physical examination when the doctor shakes the patient’s abdomen shortly after drinking water. the sound is produced by the liquid in the stomach sloshing back and forth in the obstructed stomach, indicating retained gastric material due to the blockage.

diagnosis of pyloric obstruction typically involves imaging studies like an upper gastrointestinal series or abdominal ct scan, which help visualize the blockage and its cause. endoscopy can also be used to directly view the obstruction and possibly obtain biopsies if a tumor is suspected.

management of pyloric obstruction focuses on addressing the cause of the blockage. treatment might include surgical intervention to remove the obstruction or, in cases caused by peptic ulcers, medication to reduce acid production and heal the ulcers. fluid and electrolyte imbalances due to vomiting are managed with intravenous fluids and electrolytes to prevent complications from dehydration.

in summary, pyloric obstruction is a serious gastrointestinal condition that presents with symptoms of dehydration and a succussion splash, among others. immediate medical evaluation and treatment are essential to manage the symptoms and address the underlying cause of the obstruction.
