It is important to have a strategy to assess a patient who presents with “Abdominal Pain Not Yet Diagnosed (NYD)” so that the patient can be supported while diagnostics are being done to determine the actual source of the issue. OBJECTIVES: Interpret and discuss theoretical knowledge of the pathophysiology of the conditions of the gastro-intestinal system, using critical thinking and clinical judgment for nursing practice. Discuss the impact of altered functioning of the gastrointestinal tract. Discuss overall nursing management of gastrointestinal disorders: o Assessment o Pain control o Diagnostics Explain the diagnostics used to determine the GI issue. Describe the patient experience of GI disorders.
Discuss GI function across the lifespan. NUTRITIONAL IMBALANCE: Self Study OBJECTIVES: Discuss the Nursing Process related to patients receiving a Tube Feeding.

Content Study Guide Not all of this content will be covered in class, but still may be tested. The following content questions/statements are meant to augment your learning objectives. These questions should direct your readings and help you sort out the required content as well as integrate the content from your required readings. Come to class, tutorials and labs prepared to participate in discussion and application of this information. Often, the lecture slides/materials will help to answer some of these questions for you. Print off your lecture materials and use them alongside this content study guide. Nutritional Balance: Self Study 1. What are the advantages of tube feeding vs parenteral nutrition? Tube feedings Stomach, distal duodenum, proximal jejunum Nasoduodenal/ nasojejunal indicated when the esophagus and stomach need to be bypassed or when the patient is at risk for aspiration. Gastrostomy/ jejunostomy long term feedings and medication administration Enteral nutrition is associated with fewer septic and metabolic complications compared to parenteral nutrition. Enteral nutrition is not only more physiologic but feeding enterally prevents villous atrophy and promotes the local immune function of the gut. Tube feedings are low in cost, safe well tolerated and easy to use both in extended care facilities. - Maintain fat metabolism and lipoprotein synthesis - Maintain appropriate insulin/ glucagon ratios - Preserve the usual sequence of intestinal and hepatic metabolism - Preserve GI integrity by delivery of nutrients and medications intraluminal. 2. What are the various locations that tube feeds are delivered to and what are the determinants of placement? Gastric tubes are used for decompression, drainage, aspiration and lavage. Also called NG tubes that remove fluid and gas from the upper GI tract. Sengstaken-blakemore and the Minnesota tube are used to treat bleeding esophageal varices. Commonly used gastric tubes are the Levin and the Salem Sump tube. Enteric tubes Nasoenteric tubes are used for feeding, nasoduodenal and nasal-jejunum. 3. What is osmolarity and how is it related to dumping syndrome?
Osmolality 300mmol/kg Concentration solution of high osmolality is taken in large amounts, water moves to the stomach and intestines from fluid surrounding the organs and the vascular compartment. This makes the patient feel full, nauseous and have diarrhea, this causes dehydration, hypotension and tachycardia. 4. Why would a patient with COPD require a special tube feed formula like “Pulmcare”? This formula is high in fat and low in carbohydrates and has high density that helps maintain fluid restriction and reduces co2 production. 5. What determines the type of tube feeding method that will be used? P. 954 Depends on the location of the tube in the GI tract, patient tolerance, convenience and cost. - Intermittent bolus: by gastrostomy tube in large amounts - Intermittent gravity drip: at home - Continuous feedings: slow infusion over long periods - Cyclic feeding 6. What are pros and cons of the continuous infusion method of delivering tube feeds? Continuous feedings: slow infusion over long periods - Reduces aspiration, distention, nausea, vomiting, and diarrhea in patients with poor gastric emptying or who are receiving hypertonic feeding solutions, as well as patients with severe reflux and altered mental status. - Administer tube feedings into the small intestine - Does not allow flexibility such as in intermittent feeding 7. What nursing assessments are done prior to starting tube feeds. - What is the patients nutritional status physical appearance, dietary history, recent weight loss? - Are there any existing chronic illnesses or factors that will increase metabolic demands such as fever and surgery? - What is the patient’s hydration status? Are fluid requirements being met? - Is the patient’s digestive tract functioning? - Are the patient’s kidneys functioning effectively? What is the patient’s electrolytes levels? - What medications and other therapies is the patient receiving that may affect nutritional intake and function of the digestive system? - Does the dietary prescription fulfill the patient’s needs? 8. How is a PEG tube ( percutaneous endoscopic gastrostomy) different from a tube that is inserted orally/nasally? What are potential complications from a PEG tube? PEG is a type of feeding gastronomy (opening is created into the stomach for nutrition, fluids, and medications. Complications - Wound infection, cellulitis, leakage, and abdominal wall abscess
- GI bleeding - Premature removal of the tube - Aspiration - Constipation or diarrhea 9. What nursing diagnosis and potential complications does the nurse assess for in relation to a patient who is receiving, or about to start on tube feeds? P. 956 Complications - Constipation - Diarrhea - Gas/bloating/ cramping - Nausea vomiting - Aspiration pneumonia - Nasopharyngeal irritation - Tube displacement - Tube obstruction - Dehydration - Hyperglycemia 10. What are nursing interventions related to tube feeding? P. 956 - Maintaining feeding equipment and nutritional balance - Providing medications by tube - Maintaining delivery systems - Maintaining normal bowel elimination pattern - Reducing the risk for aspiration - Maintaining adequate hydration - Promote coping ability 11. What assessments and self-management teaching will the nurse do with the patient who is going home with tube feeds? - Educate on the equipment, formula, storage, administration, water flushes Gastric and Duodenal Disorders 1. What is the relationship between H Pylori , gastritis and peptic ulcer disease (PUD)? H pylori infection in areas of gastric metaplasia induces duodenitis and enhances the susceptibility to acid injury, thereby predisposing to duodenal ulcers. 2. What are the similarities and differences between gastric and duodenal ulcers?
