Based on this information, which nursing diagnosis would be most appropriate? 1. Imbalanced Nutrition: Less than Body Requirements related to anorexia. 2. Disturbed Sleep Pattern related to epigastric pain 3. Ineffective Coping related to exacerbation of duodenal ulcer 4. Activity Intolerance related to abdominal pain 24. While caring for a client with peptic ulcer disease, the client reports that he has been nauseated most of the day and is now feeling lightheaded and dizzy. Based upon these findings, which nursing actions would be most appropriate for the nurse to take? Select all that apply. 1. Administering an antacid hourly until nausea subsides. 2.

The nurse is assessing a client 24 hours following a cholecystectomy. The nurse notes that the T-tube has drained 750ml of green-brown drainage. Which nursing intervention is most appropriate? 1. Notify the physician 2. Document the findings 3. Irrigate the T-tube 4. Clamp the T-tube 31. The nurse provides medication instructions to a client with peptic ulcer disease. Which statement, if made by the client, indicates the best understanding of the medication therapy? 1. “The cimetidine (Tagamet) will cause me to produce less stomach acid.” 2. “Sucralfate (Carafate) will change the fluid in my stomach.” 3. “Antacids will coat my stomach.” 4. “Omeprazole (Prilosec) will coat the ulcer and help it heal.” 32. The client with peptic ulcer disease is scheduled for a pyloroplasty. The client asks the nurse about the procedure. The nurse plans to respond knowing that a pyloroplasty involves: 1. Cutting the vagus nerve 2. Removing the distal portion of the stomach 3. Removal of the ulcer and a large portion of the cells that produce hydrochloric acid 4. An incision and resuturing of the pylorus to relax the muscle and enlarge the opening from the stomach to the duodenum. 33. A client with a peptic ulcer is scheduled for a vagotomy. The client asks the nurse about the purpose of this procedure. The nurse tells the client that the procedure: 1. Decreases food absorption in the stomach 2. Heals the gastric mucosa 3. Halts stress reactions 4. Reduces the stimulus to acid secretions 34. The nurse would assess the client experiencing an acute episode of cholecystitis for pain that is located in the right 1. Upper quadrant and radiates to the left scapula and shoulder 2. Upper quadrant and radiates to the right scapula and shoulder 3. Lower quadrant and radiates to the umbilicus 4. Lower quadrant and radiates to the back 35. Which of the following tasks should be included in the immediate postoperative management of a client who has undergone gastric resection? 1.

Which of the following factors should be the main focus of nursing management for a client hospitalized for cholecystitis? 1. Administration of antibiotics 2. Assessment for complications 3. Preparation for lithotripsy 4. Preparation for surgery 42. A client being treated for chronic cholecystitis should be given which of the following instructions? 1. Increase rest 2. Avoid antacids 3. Increase protein in diet 4. Use anticholinergics as prescribed 43. The client with a duodenal ulcer may exhibit which of the following findings on assessment? 1. Hematemesis 2. Malnourishment 3. Melena 4. Pain with eating 44. The pain of a duodenal ulcer can be distinguished from that of a gastric ulcer by which of the following characteristics? 1. Early satiety 2. Pain on eating 3. Dull upper epigastric pain 4. Pain on empty stomach 45. The client has orders for a nasogastric (NG) tube insertion. During the procedure, instructions that will assist in the insertion would be: 1. Instruct the client to tilt his head back for insertion in the nostril, then flex his neck for the final insertion 2. After insertion into the nostril, instruct the client to extend his neck 3. Introduce the tube with the client’s head tilted back, then instruct him to keep his head upright for final insertion 4. Instruct the client to hold his chin down, then back for insertion of the tube 46. The most important pathophysiologic factor contributing to the formation of esophageal varices is: 1. Decreased prothrombin formation 2. Decreased albumin formation by the liver 3. Portal hypertension 4. Increased central venous pressure 47. The client being treated for esophageal varices has a Sengstaken-Blakemore tube inserted to control the bleeding. The most important assessment is for the nurse to: 1. Check that the hemostat is on the bedside 2. Monitor IV fluids for the shift 3. Regularly assess respiratory status 4. Check that the balloon is deflated on a regular basis 48. A female client complains of gnawing epigastric pain for a few hours after meals. At times, when the pain is severe, vomiting occurs. Specific tests are indicated to rule out: 1. Cancer of the stomach 2. Peptic ulcer disease 3. Chronic gastritis 4. Pylorospasm 49. When a client has peptic ulcer disease, the nurse would expect a priority intervention to be: 1. Assisting in inserting a Miller-Abbott tube 2. Assisting in inserting an arterial pressure line 3. Inserting a nasogastric tube 4. Inserting an I.V. 50. A 40-year-old male client has been hospitalized with peptic ulcer disease. He is being treated with a histamine receptor antagonist (cimetidine), antacids, and diet. The nurse doing discharge planning will teach him that the action of cimetidine is to: 1. Reduce gastric acid output 2. Protect the ulcer surface 3. Inhibit the production of hydrochloric acid (HCl) 4. Inhibit vagus nerve stimulation

Answers and Rationale

1. Answer: 4. Weakness of the diaphragmatic muscle A hiatal hernia is caused by weakness of the diaphragmatic muscle and increased intra-abdominal—not intrathoracic—pressure. This weakness allows the stomach to slide into the esophagus. The esophageal supports weaken, but esophageal muscle weakness or increased esophageal muscle pressure isn’t a factor in hiatal hernia. 2. Answer: 1. Obesity Obesity may cause increased abdominal pressure that pushes the lower portion of the stomach into the thorax. 3. Answer: 3. Esophageal reflux Esophageal reflux is a common symptom of hiatal hernia. This seems to be associated with chronic exposure of the lower esophageal sphincter to the lower pressure of the thorax, making it less effective. 4. Answer: 3. Barium swallow A barium swallow with fluoroscopy shows the position of the stomach in relation to the diaphragm. A colonoscopy and a lower GI series show disorders of the intestine. 5. Answer: 1. Recognizing hemorrhage Recognizing the rupture of esophageal varices, or hemorrhage, is the focus of nursing care because the client could succumb to this quickly. Controlling blood pressure is also important because it helps reduce the risk of variceal rupture. It is also important to teach the client what varices are and what foods he should avoid such as spicy foods. 6. Answer: 4. Esophagogastroduodenoscopy (EGD) The EGD can visualize the entire upper GI tract as well as allow for tissue specimens and electrocautery if needed. The barium swallow could locate a gastric ulcer. A CT scan and an abdominal x-ray aren’t useful in the diagnosis of an ulcer. 7. Answer: 2. Reduce acid secretions Ranitidine is a histamine-2 receptor antagonist that reduces acid secretion by inhibiting gastrin secretion. 8. Answer: 3. On the left side with the head of the bed elevated 30 degrees The discomfort of reflux is aggravated by positions that compress the abdomen and the stomach. These include lying flat on the back or on the stomach after a meal of lying on the right side. The left side-lying position with the head of the bed elevated is most likely to give relief to the client. 9. Answer: 1. Irrigating the nasogastric tube In a Billroth II procedure the proximal remnant of the stomach is anastomosed to the proximal jejunum. Patency of the NG tube is critical for preventing the retention of gastric secretions. The nurse should never irrigate or reposition the gastric tube after gastric surgery, unless specifically ordered by the physician. In this situation, the nurse would clarify the order. 10. Answer: 2. Limit the fluids taken with meals The nurse should instruct the client to decrease the amount of fluid taken at meals and to avoid high carbohydrate foods including fluids such as fruit nectars; to assume a low-Fowler’s position during meals; to lie down for 30 minutes after eating to delay gastric emptying; and to take antispasmodics as prescribed. 11. Answer: 2. Use a soft toothbrush to brush the client’s teeth after each meal A soft toothbrush should be used to brush the client’s teeth after each meal and more often as needed. Mechanical cleaning is necessary to maintain oral health, simulate gingiva, and remove plaque. Assessing the oral cavity and recording observations is the responsibility of the nurse, not the nursing assistant. Swabbing with a safe foam applicator does not provide enough friction to clean the mouth. Mouthwash can be a drying irritant and is not recommended for frequent use. 12. Answer: 3. The client experiences a sudden increase in temperature The most likely complication of an endoscopic procedure is perforation. A sudden temperature spike with 1 to 2 hours after the procedure is indicative of a perforation and should be reported immediately to the physician. A sore throat is to be anticipated after an endoscopy. Clients are given sedatives during the procedure, so it is expected that they will display signs of sedation after the procedure is completed. A lack of appetite could be the result of many factors, including the disease process. 13. Answer: 2. The procedure will result in anastomosis of the gastric stump to the jejunum A Billroth II procedure bypasses the duodenum and connects the gastric stump directly to the jejunum. The pyloric sphincter is removed, along with some of the stomach fundus. 14. Answer: 1. Dark brown About 12 to 24 hours after a subtotal gastrectomy, gastric drainage is normally brown, which indicates digested blood. Bile green or cloudy white drainage is not expected during the first 12 to 24 hours after a subtotal gastrectomy. Drainage during the first 6 to 12 hours contains some bright red blood, but large amounts of blood or excessively bloody drainage should be reported to the physician promptly. 15. Answer: 3. Monitor the client for N/V, and abdominal distention Nausea, vomiting, or abdominal distention indicated that gas and secretions are accumulating within the gastric pouch due to impaired peristalsis or edema at the operative site and may indicate that the drainage system is not working properly. Saline solution is used to irrigate nasogastric tubes. Hypotonic solutions such as water increase electrolyte loss. In addition, a physician’s order is needed to irrigate the NG tube, because this procedure could disrupt the suture line. After gastric surgery, only the surgeon repositions the NG tube because of the danger of rupturing or dislodging the suture line. The amount of suction varies with the type of tube used and is ordered by the physician. High suction may create too much tension on the gastric suture line. 16. Answer: 4. Achieve optimal nutritional status through oral or parenteral feedings An appropriate expected outcome is for the client to achieve optimal nutritional status through the use of oral feedings or total parenteral nutrition (TPN). TPN may be used to supplement oral intake, or it may be used alone if the client cannot tolerate oral feedings. The client would not be expected to regain lost weight within 1 month after surgery or to tolerate a normal dietary intake of three meals per day. Nausea and vomiting would not be considered an expected outcome of gastric surgery, and regular use of antiemetics would not be anticipated. 17. Answer: 4. Aspiration of gastric contents Clients with GERD can develop pulmonary symptoms such as coughing, wheezing, and dyspnea that are caused by the aspiration of gastric contents. GERD does not predispose the client to the development of laryngeal cancer. Irritation of the esophagus and esophageal scar tissue formation can develop as a result of GERD. However, GERD is more likely to cause painful and difficult swallowing. 18. Answer: 1. Eating small, frequent meals Esophageal reflux worsens when the stomach is overdistended with food. Therefore, an important measure is to eat small, frequent meals. Fluid intake should be decreased during meals to reduce abdominal distention. Avoiding air swallowing does not prevent esophageal reflux. Food intake in the evening should be strictly limited to reduce the incidence of nighttime reflux, so bedtime snacks are not recommended. 19. Answer: 4. The ulcer has perforated The body reacts to perforation of an ulcer by immobilizing the area as much as possible. This results in boardlike muscle rigidity, usually with extreme pain. Perforation is a medical emergency requiring immediate surgical intervention because peritonitis develops quickly after perforation. An intestinal obstruction would not cause midepigastric pain. Esophageal inflammation or the development of additional ulcers would not cause a rigid, boardlike abdomen. 20. Answers: 3 and 4. Vomiting and weight loss are common with gastric ulcers. Clients with a gastric ulcer are most likely to complain of a burning epigastric pain that occurs about one hour after eating. Eating frequently aggravates the pain. Clients with duodenal ulcers are more likely to complain about pain that occurs during the night and is frequently relieved by eating. 21. Answers: 2, 4, and 5. Following a gastroscopy, the nurse should monitor the client for complications, which include perforation and the potential for aspiration. An elevated temperature, complaints of epigastric pain, or the vomiting of blood (hematemesis) are all indications of a possible perforation and should be reported promptly. A sore throat is a common occurrence following a gastroscopy. Clients are usually sedated to decrease anxiety and the nurse would anticipate that the client will be drowsy following the procedure. 22. Answer: 2. Deficient knowledge related to unfamiliarity with significant signs and symptoms Black, tarry stools are an important warning sign of bleeding in peptic ulcer disease. Digested blood in the stomach causes it to be black. The odor of the stool is very stinky. Clients with peptic ulcer disease should be instructed to report the incidence of black stools promptly to their physician. 23. Answer: 2. Disturbed Sleep Pattern related to epigastric pain Based on the data provided, the most appropriate nursing diagnosis would be Disturbed Sleep pattern. A client with a duodenal ulcer commonly awakens at night with pain. The client’s feelings of anxiety do not necessarily indicate that she is coping ineffectively. 24. Answers: 2 and 3. The symptoms of nausea and dizziness in a client with peptic ulcer disease may be indicative of hemorrhage and should not be ignored. The appropriate nursing actions at this time are for the nurse to monitor the client’s vital signs and notify the physician of the client’s symptoms. To administer an antacid hourly or to wait one hour to reassess the client would be inappropriate; prompt intervention is essential in a client who is potentially experiencing a gastrointestinal hemorrhage. The nurse would notify the physician of assessment findings and then initiate oxygen therapy if ordered by the physician. 25. Answer: 3. At bedtime Ranitidine blocks secretion of hydrochloric acid. Clients who take only one daily dose of ranitidine are usually advised to take it at bedtime to inhibit nocturnal secretion of acid. Clients who take the drug twice a day are advised to take it in the morning and at bedtime. 26. Answer: 3. The client is experiencing a side effect of the aluminum hydroxide. It is most likely that the client is experiencing a side effect of the antacid. Antacids with aluminum salt products, such as aluminum hydroxide, form insoluble salts in the body. These precipitate and accumulate in the intestines, causing constipation. Increasing dietary fiber intake or daily exercise may be a beneficial lifestyle change for the client but is not likely to relieve constipation caused by the aluminum hydroxide. Constipation, in isolation from other symptoms, is not a sign of bowel obstruction. 27. Answer: 4. “It is best for me to take my antacid 1 to 3 hours after meals.” Antacids are most effective if taken 1 to 3 hours after meals and at bedtime. When an antacid is taken on an empty stomach, the duration of the drug’s action is greatly decreased. Taking antacids 1 to 3 hours after a meal lengthens the duration of action, thus increasing the therapeutic action of the drug. Antacids should be administered about 2 hours after other medications to decrease the chance of drug interactions. It is not necessary to decrease fluid intake when taking antacids. 28. Answer: 2. Vitamin B12 Chronic gastritis causes deterioration and atrophy of the lining of the stomach, leading to the loss of the functioning parietal cells. The source of the intrinsic factor is lost, which results in the inability to absorb vitamin B12. This leads to the development of pernicious anemia. 29. Answer: 2. Indomethacin (Indocin) Indomethacin (Indocin) is a NSAID and can cause ulceration of the esophagus, stomach, duodenum, or small intestine. Indomethacin is contraindicated in a client with GI disorders. 30. Answer: 2. Document the findings Following cholecystectomy, drainage from the T-tube is initially bloody and then turns to green-brown. The drainage is measured as output. The amount of expected drainage will range from 500 to 1000 ml per day. The nurse would document the output. 31. Answer: 1 “The cimetidine (Tagamet) will cause me to produce less stomach acid.” Cimetidine (Tagamet), a histamine H2 receptor antagonist, will decrease the secretion of gastric acid. Sucralfate (Carafate) promotes healing by coating the ulcer. Antacids neutralize acid in the stomach. Omeprazole (Prilosec) inhibits gastric acid secretion. 32. Answer: 4. An incision and resuturing of the pylorus to relax the muscle and enlarge the opening from the stomach to the duodenum. Option 4 describes the procedure for a pyloroplasty. A vagotomy involves cutting the vagus nerve. A subtotal gastrectomy involves removing the distal portion of the stomach. A Billroth II procedure involves removal of the ulcer and a large portion of the tissue that produces hydrochloric acid. 33. Answer: 4. Reduces the stimulus to acid secretions A vagotomy, or cutting the vagus nerve, is done to eliminate parasympathetic stimulation of gastric secretion. 34. Answer: 2. Upper quadrant and radiates to the right scapula and shoulder During an acute “gallbladder attack,” the client may complain of severe right upper quadrant pain that radiates to the right scapula and shoulder. This is governed by the pattern on dermatomes in the body. 35. Answer: 4. Monitoring for symptoms of hemorrhage The client should be monitored closely for signs and symptoms of hemorrhage, such as bright red blood in the nasogastric tube suction, tachycardia, or a drop in blood pressure. Gastric pH may be monitored to evaluate the need for histamine-2 receptor antagonists. Bowel sounds may not return for up to 72 hours postoperatively. Nutritional needs should be addressed soon after surgery. 36. Answer: 2. Antacid administration Antacids aren’t helpful in perforation. The client should be treated with antibiotics as well as fluid, electrolyte, and blood replacement. NG tube suction should also be performed to prevent further spillage of stomach contents into the peritoneal cavity. 37. Answer: 3. To stimulate mucus production The mucosal barrier fortifiers stimulate mucus production and prevent hydrogen ion diffusion back into the mucosa, resulting in accelerated ulcer healing. Antacids neutralize acid production. 38. Answer: 4. Keep weight proportionate to height Obesity is a known cause of gallstones, and maintaining a recommended weight will help protect against gallstones. Excessive dietary intake of cholesterol is associated with the development of gallstones in many people. Dietary protein isn’t implicated in cholecystitis. Liquid protein and low-calorie diets (with rapid weight loss of more than 5 lb [2.3kg] per week) are implicated as the cause of some cases of cholecystitis. Regular exercise (30 minutes/three times a week) may help reduce weight and improve fat metabolism. Reducing stress may reduce bile production, which may also indirectly decrease the chances of developing cholecystitis. 39. Answer: 3. On deep inspiration, pain is elicited and breathing stops Murphy’s sign is elicited when the client reacts to pain and stops breathing. It’s a common finding in clients with cholecystitis. Periumbilical ecchymosis, Cullen’s sign, is present in peritonitis. Pain on deep palpation and release is rebound tenderness. Tightening up abdominal muscles in anticipation of palpation is guarding. 40. Answer: 2. Abdominal ultrasound An abdominal ultrasound can show if the gallbladder is enlarged, if gallstones are present, if the gallbladder wall is thickened, or if distention of the gallbladder lumen is present. An abdominal CT scan can be used to diagnose cholecystitis, but it usually isn’t necessary. A barium swallow looks at the stomach and the duodenum. Endoscopy looks at the esophagus, stomach, and duodenum. 41. Answer: 2. Assessment for complications The client with acute cholecystitis should first be monitored for perforation, fever, abscess, fistula, and sepsis. After assessment, antibiotics will be administered to reduce the infection. Lithotripsy is used only for a small percentage of clients. Surgery is usually done after the acute infection has subsided. 42. Answer: 4. Use anticholinergics as prescribed Conservative therapy for chronic cholecystitis includes weight reduction by increasing physical activity, a low-fat diet, antacid use to treat dyspepsia, and anticholinergic use to relax smooth muscles and reduce ductal tone and spasm, thereby reducing pain. 43. Answer: 3. Melena The client with a duodenal ulcer may have bleeding at the ulcer site, which shows up as melena (black tarry stool). The other findings are consistent with a gastric ulcer. 44. Answer: 4. Pain on empty stomach Pain on empty stomach is relieved by taking foods or antacids. The other symptoms are those of a gastric ulcer. 45. Answer: 1. Instruct the client to tilt his head back for insertion in the nostril, then flex his neck for the final insertion NG insertion technique is to have the client first tilt his head back for insertion into the nostril, then to flex his neck forward and swallow. Extension of the neck (2) will impede NG tube insertion. 46. Answer: 3. Portal hypertension As the liver cells become fatty and degenerate, they are no longer able to accommodate a large amount of blood necessary for homeostasis. The pressure in the liver increases and causes increased pressure in the venous system. As the portal pressure increases, fluid exudes into the abdominal cavity. This is called ascites. 47. Answer: 3. Regularly assess respiratory status The respiratory system can become occluded if the balloon slips and moves up the esophagus, putting pressure on the trachea. This would result in respiratory distress and should be assessed frequently. Scissors should be kept at the bedside to cut the tube if distress occurs. This is a safety intervention. 48. Answer: 2. Peptic ulcer disease Peptic ulcer disease is characteristically gnawing epigastric pain that may radiate to the back. Vomiting usually reflects pyloric spasm from muscular spasm or obstruction. Cancer (1) would not evidence pain or vomiting unless the pylorus was obstructed. 49. Answer: 3. Inserting a nasogastric tube An NG tube insertion is the most appropriate intervention because it will determine the presence of active GI bleeding. A Miller-Abbott tube (1) is a weighted, mercury-filled ballooned tube used to resolve bowel obstructions. There is no evidence of shock or fluid overload in the client; therefore, an arterial line (2) is not appropriate at this time and an IV (4) is optional. 50. Answer: 1. Reduce gastric acid output These drugs inhibit the action of histamine on the H2 receptors of parietal cells, thus reducing gastric acid output.
