Chapter 14-Nutritional Management Of The Surgical Oncology Patient Flashcards
The primary function of the small bowel is
Nutrient absorption
The primary function of the first section of the small bowel the duodenum is
Macronutrient absorption utilizing pancreatic and bile secretions
What can occur when the second portion of the small bowel, the jejunum is resected or loses portions of the jejunum?
Loss of portions of the jejunum can result in inappropriate secretion of digestive enzymes and accelerate gastric emptying
What can occur when a significant resection of the lower jejunum and ileum occurs?
This can reduce Intestinal absorption and may result in short bowel syndrome.
Short bowel syndrome is usually defined as having less than 30% of normal intestinal length or about 200 cm in adults and 75 cm in children
Gastric acid in a small bowel stimulates the release of __________ to neutralize the acid thereby protecting the function of pancreatic enzymes and bile acid
Bicarbonate
The presence of undigested food in the colon can cause bacteria to ferment and produce lactic acid. What can this cause? And how is this situation managed?
Metabolic acidosis
It is managed with refined carbohydrate restriction, antibiotics and probiotics.
What is the primary digestive function of the colon
Fluid resorption and electrolyte absorption
Partial and total resections of the colon have an impact on fluid and electrolyte balances. How long does it take the colon to adapt?
At a minimum a temporary impact or it could take 2 years or longer
Bacterial overgrowth of the terminal ileum following ileocecal valve resection can reduce_________ absorption and result in the need for supplementation
Vitamin B12
Cancer patients with an ileostomy are at increased risk for________ and ______. There is an increased need for _________ and ___________
Dehydration and electrolyte abnormalities
Sodium and water
Cancer patients with an ileostomy s.hould consume more water than their ostomy. How much water should they consume?
They should consume at least one more liter of fluid than their ostomy output
What is the main function of the pancreas?
Production of bicarbonate and pancreatic enzymes, which are important or macronutrient digestion
What is the main role of the liver?
Nutrient metabolism
After intestinal surgery, what are the most common side effects?
Nausea, abdominal cramping and diarrhea
After intestinal surgery how long should one follow a diet to avoid the side effects after surgery?
Four to six weeks
