Check tube placement before feeding and each drug administration. 2. Assess for bowel sounds before feeding. 3. Use liquid medications rather than pills. • Dilute viscous liquid medications. • Do not add medications to enteral feeding formula. 4. If using tablets, crush drugs to a fine powder and dissolve in water to avoid clogging 5. Follow measures to decrease aspiration risk: • Keep HOB elevated to 30- to 45-degree angle. • Check for residual volumes per facility policy. 6. Assess regularly for complications (e.g., aspiration, diarrhea, abdominal distention, hyperglycemia, constipation, and fecal impaction). NG tube insertion - ANSWER Use a guide wire to help with correct placement **never put guidewire back in Goes in through the nares through the oesophagus and into the stomach and may go into the duodenum -Have patient swallow when passing through the throat For a patient with an NG tub, what task can be delegated? - ANSWER LPN: • Insert NG tube for stable patient. • Irrigate NG and gastrostomy tubes. • Give bolus or continuous enteral feeding for stable patient. • Remove NG tube. • Give medications through NG or gastrostomy tube to stable patient. • Provide skin care around gastrostomy or jejunostomy tubes. UAP: • Provide oral care • Weigh pt .• Position and maintain patient with the head of bed elevated. • Notify RN or LPN about patient symptoms (e.g., nausea, diarrhea) that may indicate problems with enteral feedings. • Alert RN or LPN about enteral feeding infusion pump alarms. • Empty drainage devices and measure output. Gastrostomy tube - ANSWER nutrition, medication; proper technique for use, verify placement, monitor for infection, HOB elevated Ileostomy - ANSWER semiliquid, fluid needs increased -should be observed for signs and symptoms of fluid and electrolyte imbalance, particularly potassium, sodium, and fluid deficits. Colonostomy - ANSWER Ascending- semiliquid stool, fluid needs increased Transverse- semiliquid to semi formed stool, possibly increased fluid needs Sigmoid- formed stool, no change in fluid needs, can regulate bowel patterns Diarrhea - ANSWER Assessment- loose stools, abdominal cramps, pain, fever Complications: dehydration, electrolyte imbalance, intestinal perforation Management: self limiting, replace fluids and electrolytes, diet, protect skin, isolation, stool culture, anti-diarrheals, antibiotics Constipation - ANSWER Assessment- stools are absent or hard, dry, and difficult to pass, abdominal distention, bloating, increased flatulence and increased rectal pressure Complications- hemorrhoids, perforation, rectal mucosal ulcers and fissures Diagnostics: abdominal x-rays, barium enema, colonoscopy, sigmoidoscopy Management: increasing dietary fiber, fluid intake (2L/ days), exercise, laxatives, enemas, do not delay defecation gastroesophageal reflux disease (GERD) - ANSWER Assessment- heartburn, dyspepsia, regurgitation, coughing Complications- esophagitis, asthma, Barrets oesophagus, pneumonia Tests: endoscopy, biopsies, barium swallow, motility studies -Management- smoking cessation, nutrition (no alcohol/caffeine/acidic foods), weight loss, HOB elevated, medications, surgery, endoscopic therapy GERD acronym - ANSWER G- generally known as heartburn E- epigastric pain and spasm usually follow a meal R- radiating pain to arms arms and chest is common D- diet therapy Hiatal hernia - ANSWER Two types: sliding and rolling (can be emergency) Assessment: asymptomatic or resemble GERD Complications: strangulation, GERD, esophagitis, hemorrhage, ulcerations Tests: esophagram (barium swallow) Management: similar to GERD, surgery Peptic ulcer disease - ANSWER condition characterized by erosion of the GI mucosa from the digestive action of hydrochloric acid and pepsin -pH increases to 3.5 or more when foods or antacids neutralize stomach acid or drugs block acid secretion -H. pylori is main organism of PUD - Any portion of the GI tract that comes into contact with gastric secretions is susceptible to ulcer development Gastric or duodenal (differ in their incidence and presentation Lifestyle factors: alcohol and coffee stimulate acid secretion and smoking and psychologic distress What does Helicobacter pylori cause? - ANSWER Ulcers bc of its production of enzyme urease -•Urease activates immune response •Antibody production •Release of inflammatory cytokines •Response to H. pylori is variable
