Ch 45 Nursing Care of a Family when a child has a Gastrointestinal Disorder

The nurse is discussing the treatment of congenital aganglionic megacolon with the caregivers of a child diagnosed with this disorder. Which statement is the best explanation of the treatment for this diagnosis?

"The treatment for the disorder will be a surgical procedure." Treatment of congenital aganglionic megacolon involves surgery with the ultimate resection of the aganglionic portion of the bowel. Chronic anemia may be present, but iron will not correct the disorder. Enemas may be given to initially achieve bowel elimination, but they will not treat the disorder. Differentiation must be made between this condition and psychogenic megacolon because of coercive toileting or other emotional problems. The child with aganglionic megacolon does not withhold stools or defecate in inappropriate places, and no soiling occurs.

A child presents with intermittent abdominal pain, severe anorexia, and diarrhea. The child's height and weight are significantly behind standards for age. There is skin breakdown in the anal region. The nurse explains that this presentation is consistent with which diagnosis?

Crohn disease Intermittent abdominal pain, anorexia, diarrhea, growth delays, and perianal lesions are characteristic of Crohn disease. In ulcerative colitis, the pain is continuous with bloody diarrhea, but anorexia, weight loss, and growth delay are mild. Food poisoning is an acute condition and may result in weight loss but not growth delays. In Hirschsprung disease the bowel lacks nerve innervation, so it lacks motility and fecal output.

The nurse is caring for a child with a diagnosis of pyloric stenosis during the preoperative phase of the child's treatment. What is the highest priority at this time?

Improving hydration Preoperatively, the highest priority for the child with pyloric stenosis is to improve nutrition and hydration. Maintaining mouth and skin integrity, and relieving family anxiety are important, but these are not the priority. The child will not likely have intense pain. Preparing the family for home care would be a postoperative goal.

The nurse is determining maintenance fluid requirements for a child who weighs 25 kg (55 lb). How much fluid would the child need per day?

1,600 ml Using the following formula of 100 ml/kg for the first 10 kg, plus 50 ml/kg for the next 10 kg, and then 20 ml/kg for the remaining kg, the child would require (100 × 10) + (50 × 10) + (20 × 5) = 1,000 + 500 + 100 = 1,600 mL in 24 hours.

An infant is diagnosed with gastrointestinal reflux. The nurse instructs the mother to feed the infant formula thickened with rice cereal. The infant typically drinks 4 oz (120 ml) of formula at a feeding. How much rice cereal would the nurse instruct the mother to add to the feeding?

4 Typically, 1 tablespoon (5 ml) of rice cereal is added for each ounce of formula. This infant is drinking 4 oz (120 ml) of formula, thus 4 tablespoons (20 ml) of rice cereal will be added.

The nurse is reinforcing dietary teaching with the caregiver of a child diagnosed with celiac syndrome. Which foods would be permitted in the diet of the child with celiac syndrome? Select all that apply.

Bananas Skim milk Applesauce The child is usually started on a gluten-free, low-fat diet. Skim milk and bananas are usually well tolerated. Lean meats, puréed vegetables, and fruits are gradually added to the diet. Wheat, rye, oats (unless specifically gluten free), corn flour (corn itself is okay), and cornmeal are not included in the diet.

A child is diagnosed with intussusception. The nurse anticipates that what action would be attempted first to reduce this condition?

Barium enema A barium enema is successful in reducing a large percentage of intussusception cases. Other cases are reduced surgically. Upper endoscopy is used to visualize the upper gastrointestinal tract from the mouth to the upper jejunum. Endoscopic retrograde cholangiopancreatography is used to view the hepatobiliary system.

The nurse recognizes that in the disorder referred to as rickets, the child has a lack of vitamin D. Because of the lack of vitamin D, the absorption of which of the following is decreased?

Calcium and phosphorus Rickets, a disease affecting the growth and calcification of bones, is caused by a lack of vitamin D. The absorption of calcium and phosphorus is diminished because of the lack of vitamin D, which is needed to regulate the use of these minerals. The absorption of the other nutrients is not affected by the lack of vitamin D.

The nurse is providing care to a child with an intussusception. The child has a bowel movement and the nurse inspects the stool. The nurse would most likely document the stool's appearance as having what quality?

Currant jelly-like The child with intussusception often exhibits currant jelly-like stools that may or may not be positive for blood. Greasy stools are associated with celiac disease. Clay-colored stools are observed with biliary atresia. Bloody stools can be seen with several gastrointestinal disorders, such as inflammatory bowel disease.

The nurse is developing a teaching plan for the parents of an 11-month-old infant with gastroesophageal reflux disease (GERD). The child will be managed medically. What actions would the nurse incorporate into the teaching plan? Select all that apply.

Keeping the child upright for 30 minutes after feeding Giving the child small frequent feedings Administering prokinetics to empty the stomach quickly For the infant with GERD, the parents should give the child small, frequent feedings, with frequent burping to control reflux. The parents also should keep the child upright for 30 to 45 minutes after a feeding and thicken formula with rice or oatmeal cereal. Prokinetics may be used to help empty the stomach more quickly, minimizing the amount of gastric contents in the stomach that the child can reflux.

A 10-year-old male presents with low-grade fever, nausea, and abdominal pain. The nurse examining him suspects appendicitis and checks for rebound tenderness in what quadrant?

Lower right With appendicitis, percussion reveals irritation and pain in the right lower quadrant. Rebound tenderness present with palpation in the right lower quadrant is referred to as the McBurney point, an area of tenderness 1.5 to 2 inches (3.8 to 5 cm) in from the right anterior superior iliac spine along a line extending to the umbilicus.

The nurse is discussing the disease known as pellagra. This disease is due to a deficiency in which of the following?

Niacin Niacin insufficiency in the diet causes a disease known as pellagra, which presents with GI and neurologic symptoms. A diet deficient in thiamine causes beriberi. Lack of vitamin C causes scurvy, and lack of iron causes anemia.

Which congenital condition leads to the infant being hungry, irritable, losing weight and rapidly becoming dehydrated with the potential of metabolic alkalosis?

Pyloric stenosis This clinical picture includes assessment findings consistent with pyloric stenosis. Theses infants are very hungry yet once they eat, regurgitate the feeding leading to the infant being irritable, losing weight, and becoming dehydrated. The infant with aganglionic megacolon has a main symptom of constipation. Intussusception is a painful telescoping of the bowel. Colic has similar symptoms but primarily includes bouts of abdominal pain.

The incidence of vitamin D deficiency in the United States is less than in many countries. What is the most likely reason for this?

Some foods in the U.S. have been fortified with vitamin D. Whole milk and evaporated milk fortified with 400 U of vitamin D per quart are available throughout the United States, which decreases the vitamin D deficiency of children in the U.S. Vitamin D can be administered orally in the form of fish liver oil or synthetic vitamin, but this is not common for children in the U.S. Water is not fortified with vitamin D, and some communities in the U.S. do not get adequate sunshine to meet vitamin D needs.

The nurse is caring for an infant immediately after a pyloromyotomy surgery has been performed to treat pyloric stenosis. The infant's parents are understandably anxious about their child. Given the situation, what is the most appropriate way for the nurse to position the infant during the anesthesia recovery period?

Support him and place him on his side. Postoperatively the child should be placed on his side to prevent aspiration of mucus or vomitus, especially during the anesthesia recovery period. After fully waking from the surgery, he can be held by a family caregiver in a position that does not interfere with IV infusions and is comforting to both caregiver and child.

A child is diagnosed with intussusception. The nurse would prepare the child and family for which of the following?

Surgery Intussusception is a surgical emergency and must be promptly reduced either by instillation of a water-soluble solution, barium enema, or air into the bowel, or surgery to reduce the invagination before necrosis of the affected portion of the bowel occurs. The point of invagination is usually at the juncture of the distal ileum and proximal colon. Therefore, an upper endoscopy or barium swallow would be inappropriate. The condition must be reduced; thus, an abdominal computed tomography would be ineffective.

Nurses will need to teach the parents of the infant being treated for Hirschsprung disease (aganglionic megacolon) to:

care for a temporary colostomy. The aganglionic portion of the infant's colon will need to be removed. In most cases, bowel is allowed to rest and recoil for a period of time, necessitating a temporary colostomy. Later the colostomy can be closed and the two ends of the intestine rejoined. Thickening feedings will not relieve the colon distention and obstruction with stool. Pacifiers may be used and are soothing. Monitoring heart rate should not be necessary.

Pyloric stenosis has been diagnosed in a 3-week-old male infant who has frequent vomiting after feedings. An important preoperative nursing intervention is:

maintaining NPO status while restoring hydration and electrolyte balance. NPO is needed to avoid vomiting and aspiration during surgery. Hydration and electrolyte replacement is often needed because of the history of vomiting, which causes loss of both fluid and electrolytes. Feeding when surgery is pending would not be safe. Hourly abdominal assessment would not yield needed information and would further disturb the infant. Pain is not the source of crying. The infant is hungry.

The nurse has admitted a child to the pediatric unit with diarrhea and vomiting. Accurate intake and output are important care measures for the child. The nurse correctly assesses that output parameters should be:

0.5 to 1 mL/kg/hr. The child's hourly output should be 0.5 to 1 mL/kg/hour. Output of 0.5 to 1 mL/kg/shift and 2 to 4 mL/kg/shift would be inadequate output for the child. Output of 2 to 4 mL/kg/hr is higher than necessary for adequate hydration.

The nurse is providing care for a child who has been diagnosed with rickets. What is the nurse's priority intervention?

Administration of adequate vitamin D Rickets results from inadequate vitamin D; supplements are necessary. There is no direct need to increase calorie, thiamine or protein intake.

In understanding the disease of marasmus when seen in children, the nurse recognizes that the disease is caused because of which of the following?

Deficiency of protein and calories Marasmus is a deficiency in calories as well as protein. Scurvy is caused by inadequate intake of vitamin C, and anemia is caused by lack of iron. Excess calories add to the concern of obesity in children. Excess vitamin C is excreted, and it is unusual to have an excess of iron or protein in the diet of children; those nutrients are more often inadequate in children's diets.

The nurse is teaching an in-service program to a group of nurses on the topic of gastrointestinal disorders. The nurses in the group make the following statements. Which statement is most accurate related to the diagnosis of gastroesophageal reflux?

In this disorder the sphincter that leads into the stomach is relaxed. Gastroesophageal reflux (GER) occurs when the sphincter in the lower portion of the esophagus, which leads into the stomach, is relaxed and allows gastric contents to be regurgitated back into the esophagus. Congenital aganglionic megacolon is characterized by persistent constipation resulting from partial or complete intestinal obstruction of mechanical origin. Colic consists of recurrent paroxysmal bouts of abdominal pain. Pyloric stenosis is characterized by hypertrophy of the circular muscle fibers of the pylorus, which leads to an obstruction at the distal end of the stomach.

The nurse has developed a plan of care for a 12-month-old hospitalized with dehydration as a result of rotavirus. Which intervention would the nurse include in the plan of care?

Maintaining the intravenous (IV) fluid rate as ordered The nurse should maintain an IV line and administer the IV fluid as ordered to maintain fluid volume. High-carbohydrate fluids like fruit juice, Kool-Aid, and popsicles should be avoided as they are low in electrolytes, increase simple carbohydrate consumption, and can decrease stool transit time. Milk products should be avoided during the acute phase of illness as they may worsen diarrhea.

A mother calls the doctor's office and tells the nurse that she is concerned because her 4-month-old keeps "spitting up" with every feeding. What would indicate that the child is regurgitating as opposed to vomiting?

Only occurs with feeding Regurgitation typically occurs only with feeding, runs out of the mouth with little force, smells barely sour and is only slightly curdled, appears to cause no pain or distress, occurs only once per feeding, and amounts to only about 1 to 2 tsp. Vomiting may occur at times other than feeding, is forceful and is typically projected 1 ft or more away from infant, is extremely sour smelling and curdled, is typically accompanied by crying, continues until the stomach is empty, and amounts to the full stomach contents.

When examining the abdomen of a child, which technique would the nurse use last?

Palpation Palpation should be the last part of the abdominal examination. Inspection, auscultation, and percussion should be done before palpation.

A 9-month-old girl is brought to the emergency room with what appears to be bouts of intense abdominal pain 15 minutes apart in which she draws up her legs and cries, often accompanied by vomiting. In between the bouts, the child recovers and appears to be without symptoms. Blood is found in the stool. What condition should the nurse suspect in this case?

Intussusception Intussusception, the invagination of one portion of the intestine into another, usually occurs in the second half of the first year of life. Children with this disorder suddenly draw up their legs and cry as if they are in severe pain; they may vomit. After the peristaltic wave that caused the discomfort passes, they are symptom-free and play happily. In approximately 15 minutes, however, the same phenomenon of intense abdominal pain strikes again. After approximately 12 hours, blood appears in the stool and possibly in vomitus, described as a "currant jelly" appearance. Volvulus with malrotation and necrotizing enterocolitis typically occur in the first 6 months of life and do not match the symptoms described above. Short-bowel/short-gut syndrome typically occurs when a large portion of the intestine has been removed due to a previous disease or trauma.

The nurse admits an infant who is nutritionally deprived. The infant is weak and seems somewhat uninterested in food. In developing the infant's plan of care, how often will the nurse most likely plan to feed this infant?

Every 2 or 3 hours For the child who is nutritionally deprived, scheduling feedings every 2 or 3 hours is best because most weak babies can handle frequent, small feedings better than feedings every 4 hours. Feeding every hour would not give the weak child an adequate amount of time to rest and sleep between feedings.

The nurse is caring for a 6-month-old infant who was admitted to the emergency room 24 hours ago with signs of severe diarrhea. The infant's rectal temperature is 104°F (40°C), with weak and rapid pulse and respirations. The skin is pale and cool. The child is on IV rehydration therapy, but the diarrhea is persisting. The infant has not voided since being admitted. Which is the priority nursing intervention?

Take a stool culture Treatment of severe diarrhea focuses on regulating electrolyte and fluid balance by initiating a temporary rest for the gastrointestinal tract, oral or IV rehydration therapy, and discovering the organism responsible for the diarrhea. All children with severe diarrhea or diarrhea that persists longer than 24 hours should have a stool culture taken to determine if bacteria are causing the diarrhea; if so, a definite antibiotic therapy can be prescribed. Because a side effect of many antibiotics is diarrhea, antibiotics should not routinely be used to treat diarrhea without an identifiable bacterial cause. Before the initial IV fluid is changed to a potassium solution, be certain the infant or child has voided—proof that the kidneys are functioning; in this case, the child is not voiding yet. The child should not be fed a cracker, as the gastrointestinal tract should be rested until the diarrhea stops.

A young child has presented to the pediatric unit with a swollen abdomen, edema, thin patchy hair, and irritability with growth retardation and muscle wasting. The nurse suspects a malnutrition disorder. The nurse identifies this child to most likely have which condition?

Kwashiorkor The symptoms presented are classic signs of Kwashiorkor due to the protein deficiency.

A 12-year-old boy has just undergone a liver transplantation and is recovering. After performing a fingerstick puncture and assessing the results, the nurse administers a 10% solution of dextrose IV. What is the correct rationale for this intervention?

Prevention of hypoglycemia Hypoglycemia is a major danger following liver transplantation because glucose levels are regulated by the liver, and the transplanted organ may not function efficiently at first. Assess serum glucose levels hourly by fingerstick puncture. A 10% solution of dextrose IV may be necessary to prevent hypoglycemia. Careful tissue matching before the transplantation is needed to reduce the possibility of stimulating T-cell rejection. Sodium, potassium, chloride, and calcium levels are evaluated approximately every 6 to 8 hours to be certain electrolyte balance is maintained, but potassium is rarely added to IV solutions because of the risk that renal failure has occurred. IV therapy with hypotensive agents such as hydralazine and nitroprusside may be needed to reduce hypertension.

The nurse is doing teaching with the caregivers of toddler and preschool aged-children. One of the caregivers tells the group that her child had diarrhea and she was told that it was caused by giardiasis. Which statement made by the caregiver indicates the most likely situation in which the child contacted the disorder?

"He attends a day care center four days a week while I am at work." Giardiasis is caused by the protozoan parasite Giardia lamblia. It is a common cause of diarrhea and is prevalent in children who attend day care centers and other types of residential facilities; it may be found in contaminated mountain streams or pools frequented by diapered infants. Bubble baths can lead to urinary tract infections, but are not the cause of Giardiasis infestations. It is not related to either C. Diff or pinworms.

While observing the parents of a neonate with pyloric stenosis feeding the baby, the nurse notes that the parents are becoming frustrated. The nurse identifies a nursing diagnosis of risk for impaired parenting related to frustration and difficulty feeding neonate. Which would be appropriate for the nurse to include in the plan of care? Select all that apply.

Encouraging rooming in with the neonate Assisting the parents in holding and feeding their neonate Pointing out positive aspects about their neonate For a nursing diagnosis of risk for impaired parented, appropriate interventions include encouraging the parents to room in with their neonate, helping them understand that the cause of the condition is a physical problem, not something they did, assisting the parents in holding and feeding their neonate, and pointing out positive aspects about their neonate.

A child aged 3 months has been spitting up regularly since birth and is somewhat underweight. The nurse suggests which interventions to the parents? Select all that apply.

Thicken feedings with rice cereal. Feed smaller amounts more frequently. Burp well when feeding. Thickened feedings are heavier than formula/breast milk, making them more difficult to spit up. The rice cereal also adds calories that this infant needs. Smaller, frequent feedings and burping well prevent distending the stomach and reduce the likelihood of reflux. The best position following feeding is upright. The supine position creates pressure on the lower esophageal sphincter, which promotes reflux.

The nurse is conducting a physical examination of a child with suspected Crohn disease. Which finding would be the most suspicious of Crohn disease?

Perianal skin tags or fissures Perianal skin tags and/or fissures are highly suspicious of Crohn disease. Poor growth pattern, hunger and abdominal tenderness are common to Crohn disease but are also seen with many other conditions. Normal growth patterns would not point to Crohn disease because of problems with absorbing nutrients.

A mother is alarmed because her 6-week-old boy has begun vomiting almost immediately after every feeding. In the past week, the vomiting has grown more forceful, with the vomit projecting several feet from his mouth. He is always hungry again just after vomiting. At the physician's office, the nurse holds the child and gives him a bottle of water. While he drinks, she notes an olive-size lump in his right abdomen. Which condition should the nurse suspect in this child?

Pyloric stenosis With pyloric stenosis, at 4 to 6 weeks of age, infants typically begin to vomit almost immediately after each feeding. The vomiting grows increasingly forceful until it is projectile, possibly projecting as much as 3 to 4 feet. Infants are usually hungry immediately after vomiting because they are not nauseated. A definitive diagnosis can be made by watching the infant drink. If a pyloric stenosis is present, the sphincter feels round and firm, approximately the size of an olive in the right abdomen. Peptic ulcer disease in neonates usually presents with hematemesis (blood in vomitus) or melena (blood in the stool). Gastroesophageal reflux involves a small (1-2 tsp) volume and is not forceful. Appendicitis typically begins with anorexia for 12 to 24 hours; children do not eat and do not act like their usual selves. Nausea and vomiting may then occur, followed by diffuse abdominal pain.

The nurse is teaching an in-service program to a group of nurses on the topic of children diagnosed with Kwashiorkor. The nurses in the group make the following statements. Which statement is most accurate related to the diagnosis of Kwashiorkor?

"It is important to increase the intake of protein for these children." Kwashiorkor results from severe deficiency of protein with an adequate caloric intake. It accounts for most of the malnutrition in the world's children today. The highest incidence is in children 4 months to 5 years of age. Although strenuous efforts are being made around the world to prevent this condition, its causes are complex.

The nurse is educating a family on celiac syndrome. Which is conclusive and confirms the diagnosis?

Biopsy of the jejunum through endoscopy showing changes in villi All of the options relate to ways of determining if there is a possibility that a client has celiac syndrome. Conclusive diagnosis is made with an endoscopy and biopsy of the jejunum.

A child with severe diarrhea cannot drink and requires intravenous rehydration. After beginning the therapy, the nurse determines that potassium can be added to the intravenous fluid because which of the following has occurred?

The child has voided. Potassium cannot be given until it is established that the child is not in renal failure. Giving potassium IV when the body has no outlet for excessive potassium can lead to excessively high potassium levels and heart block. Before initial IV fluid is changed to a potassium solution, the nurse must be certain that the infant or child has voided—proof that the kidneys are functioning.

A parent brings a 2-year-old child to the health clinic with reports of diarrhea, vomiting, and abdominal pain. The father tells the nurse that he is a single parent and his child is enrolled in a local day care center. Based on this information, what gastrointestinal condition might the nurse suspect?

Gastroenteritis Outbreaks of gastroenteritis routinely occur in day care centers, schools, institutions for the handicapped, and other places where overcrowding is prevalent and hygiene is inadequate. Typical signs and symptoms include diarrhea, nausea, vomiting, and abdominal pain.

The nurse admits a 7-year-old child who reports pain in the lower right quadrant of the abdomen, nausea, and constipation. An assessment shows that the child has a fever of 101℉ (38.3℃). Which nursing intervention should the nurse implement to safely address the child's reported pain?

Help the child find a comfortable position. The child's symptoms indicate possible appendicitis. When appendicitis is suspected, laxatives and enemas are contraindicated because they increase peristalsis, which increases the possibility of rupturing an inflamed appendix. Heat to the abdomen is also contraindicated because of the danger of rupture of the appendix. Medicating with analgesics is inappropriate, because medication may conceal signs of tenderness that are important for diagnosis. Comfort can be provided through positioning.

A neonatal nurse teaches students how to recognize gastrointestinal disorders in infants. The nurse tells the students that failure of the newborn to pass meconium in the first 24 hours after birth may indicate what disease?

Hirschsprung disease The nurse should suspect Hirschsprung disease when the newborn does not pass meconium in the first 24 hours after birth, and has bilious vomiting or abdominal distention and feeding intolerance with bilious aspirates and vomiting. Typical signs and symptoms of gastroenteritis include diarrhea, nausea, vomiting, and abdominal pain. The characteristic GI manifestation of UC is bloody diarrhea accompanied by crampy, typically left-sided lower abdominal pain. Clinical manifestations of untreated SBS include profuse watery diarrhea, malabsorption, and failure to thrive.

The nurse is caring for an infant with a temporary ileostomy. As part of the plan of care, the nurse monitors for skin breakdown around the stoma. If redness occurs, what would be most appropriate to promote healing and prevent further skin breakdown?

Apply a barrier/healing cream or paste on the skin. The nurse should use a barrier/healing cream or paste on the skin around the stoma to promote healing and prevent further skin breakdown. Diaper wipes that contain fragrance or alcohol can sting if used on nonintact skin and can worsen skin breakdown. The barrier wafer would be helpful, but does not address the skin breakdown.

The nurse completes a 1-month-old's feeding and sits the infant up to burp. The infant vomits back the feeding. Which is the nurse's primary concern?

Aspiration The primary concern for the nurse is that the infant aspirates vomit into the lungs. Aspiration after vomiting may lead to respiratory concerns such as apnea and pneumonia. Nutritional deficiencies may occur if the vomiting continues. This is a concern but not the primary concern. Stomach irritation and stunted growth is not a typical concern at this time.

A child is admitted with a temperature, 101.2°F (38.4°C); pulse rate 100 beats/min; respirations 24 breaths/min. On admission the pain is localized in right lower quadrant. Legs are drawn up against the abdomen. Bowel sounds are sluggish. Rebound tenderness is present. White blood cell count of 17,000/mm3. Ultrasound confirms appendicitis. Which instruction would the nurse give to the child and the parent?

Do not rub or put pressure on the abdomen. The nurse would instruct the child/parent to not rub or put pressure on the abdomen as palpating an inflamed appendix may cause it to rupture. A child with appendicitis will be NPO for surgery and therefore not instructed to drink. Heat to the abdomen may also cause the inflamed appendix to rupture. Ice is not an effective intervention.

An infant brought to the emergency department has been vomiting for 2 days. The nurse assesses the infant and finds sunken fontanels, tenting skin, dry mucus membranes and no urine output for 12 hours. Which intervention(s) will the nurse complete as first-line care for this infant ? Select all that apply.

Insert a peripheral IV. Administer a prescribed IV fluid bolus. Administer an antiemetic. This infant is showing signs of severe dehydration. These symptoms include sunken fontanels, tenting of the skin, dry mucus membranes, delayed capillary refill, and increased heart rate and a urine output of less than 1ml/kg/hr. The nurse will need to insert a peripheral IV and begin the prescribed bolus IV infusion. After the bolus has been completed, the infant would need to be reassessed for urine output and symptom improvement. The health care provider would then prescribe another IV bolus or to begin maintenance IV fluids. Antiemetics can be prescribed is necessary. Oral rehydration is used for mild or moderate dehydration.

What occurs in the gastrointestinal system of the child with Hirschsprung disease?

There is a partial or complete mechanical obstruction in the intestine. Congenital aganglionic megacolon, also called Hirschsprung disease, is characterized by persistent constipation resulting from partial or complete intestinal obstruction of mechanical origin. A narrowing of the lumen of the pylorus is associated with pyloric stenosis in young infants. The telescoping of the bowel is intussusception. The relaxed sphincter in the lower portion of the esophagus is related to gastrointestinal reflux disorder.

Which type of nutrition would the nurse expect to administer to a preterm infant who was born at 34 weeks' gestation and has developed necrotizing enterocolitis (NEC)?

Total parenteral nutrition (TPN) Total parenteral nutrition (TPN) should be administered to preterm infants with necrotizing enterocolitis. In NEC, there is acute inflammation of the bowel associated with ischemia. This can lead to bowel necrosis and perforation. Preterm infants are at higher risk of developing NEC, due to gastric immaturity and an increased risk of infections. When NEC is detected in the preterm infant, TPN should be administered and enteral feeding should be withheld until the condition stabilizes. Gavage feeding and trophic feeding are different forms of enteral feeding given to preterm infants, but not to those having NEC. Oral breastfeeding should also be withheld in NEC. NEC is treated with IV fluids, antibiotics, blood transfusion and surgical resection of the segment.
