GASTROINTESTINAL NURSING Digestive Tract Disorders 2013
Anatomy and Physiology of the Digestive Tract Mouth Where teeth, tongue, and salivary glands begin food digestion Pharynx Muscular structure shared by the digestive and respiratory tracts It joins the mouth and nasal passages to the esophagus Esophagus Long muscular tube that passes through the diaphragm into the stomach Stomach Churns and mixes food with gastric secretions until a semiliquid mass called chyme
Anatomy and Physiology of the Digestive Tract Small intestine Chemical digestion and absorption of nutrients take place Approximately 20 feet long and consists of three sections: the duodenum, the jejunum, and the ileum Liver and pancreatic secretions enter the digestive tract in the duodenum
Anatomy and Physiology of the Digestive Tract Large intestine and anus The first section of the large intestine is the cecum Ascending colongoes up right side of the abdomen Transverse colon crosses abdomen just below waist Descending colon goes down left side of abdomen The last 6 to 8 inches of the large intestine is the rectum, which ends at the anus, where wastes leave the body
Age-Related Changes Teeth are mechanically worn down with age The jaw may be affected by osteoarthritis A significant loss of taste buds with age Xerostomia (dry mouth) is common Walls of esophagus and stomach thin with aging, and secretions lessen Production of hydrochloric acid and digestive enzymes decreases Gastric motor activity slows Movement of contents through the colon is slower Anal sphincter tone and strength decrease
Nursing Assessment and Health History ?? Common complaints of GI system Why is past medical history important?? What family history might be relevant?? What are some common questions you need to ask in your review of systems???

Total Parenteral Nutrition – (TPN) • Nutritionally complete • Used when GI system not functioning • Short or long term
Critical Thinking Exercise A 71 y.o. woman who underwent a bowel resection for the removal of a tumor is receiving TPN through a central venous catheter. The patient’s fingerstick blood glucose is 250 mg/dl, and the patient’s temp is 102 F and the nurse notes puralent drainage at the catheter insertion site.
