Gastrointestinal

A nurse is reviewing the record of a client with Crohn's disease. Which of the following stool characteristics would the nurse expect to see documented in the record?

Diarrhea Rationale: Crohn's disease is characterized by non-bloody diarrhea of usually not more than four or five stools daily. Over time, the diarrhea episodes increase in frequency, duration, and severity.

A client with a possible hiatal hernia complains of frequent heartburn and regurgitation. Which sign or symptom would support this diagnosis?

Difficulty swallowing both liquids and solids Rationale: Although many clients with a hiatal hernia are asymptomatic, those with symptoms usually have difficulty swallowing along with heartburn and reflux.

A client is seen in the ambulatory care office for a routine examination. Which statement by the client would be important for the nurse to follow up?

"I just lost a family to gastrointestinal cancer." Rationale: The nurse should recognize and follow up on the statement about familial cancer. The client may have some anxiety that this will ultimately occur to him, and the nurse should gather further data to understand the client's situation. Gathering data about the types of cancer, age, and sex of affected family members, and the presence of other risk factors provides the needed information to initiate preventive education.

A client who has undergone barium enema is being readied for discharge. The nurse determines that the client has understood discharge instructions when the client states:

"I should take a laxative, and my stool will then return to a normal color." Rationale: Discharge teaching following this procedure includes that the client should take a laxative to enhance passage of remaining barium from the bowel to prevent impaction. Laxatives are not taken fairly frequently because this practice can promote dependency. Stools change from clay-colored back to a normal color once all barium is eliminated. The information contained in the client's other statements do not reflect accurate discharge teaching.

A nurse is collecting data from a client admitted to the hospital with a diagnosis of suspected gastric ulcer and is asking the client questions about pain. Which statement, if made by the client, would support the diagnosis of gastric ulcer?

"My pain comes shortly after I eat, maybe a half hour or so later." Rationale: Gastric ulcer pain often occurs in the upper epigastrium, with localization to the left of the midline, and may be exacerbated by food. The pain occurs a half hour to an hour after a meal and rarely occurs at night. Duodenal ulcer pain is usually located to the right of the epigastrium. The pain associated with a duodenal ulcer occurs 90 minutes to 3 hours after eating and often awakens the client at night.

A client has had extensive surgery on the gastrointestinal tract and has been started on parenteral nutrition (PN). The client tells the nurse, "I think I'm going crazy...I feel like I'm starving and yet that bag is supposed to be feeding me." The best response of the nurse would be:

"That is because the empty stomach sends signals to the brain to stimulate hunger." Rationale: The stomach does send signals to the brain when it is empty to stimulate hunger. The client should be told that this is normal. Some clients also experience food cravings for the same reason.

A client is admitted to an acute care facility with complications of celiac disease. Which question would be helpful initially in obtaining information for the nursing care plan?

"What is your understanding of celiac disease?" Rationale: Celiac disease is also known as "gluten-induced enteropathy." It causes diseased intestinal villi, which results in decreased absorptive surfaces and malabsorption syndrome. Clients with celiac disease must maintain a gluten-free diet, which eliminates all products made from wheat, rye, oats, barley, buckwheat, or graham. Many products may contain gluten without the client's knowledge. Beer, pasta, crackers, cereals, and many more substances contain gluten. It is often very difficult for a client to learn all of the food substances that must be eliminated from a diet. Also it is often very difficult for a client to adhere to a strict diet. Therefore initially it is important for the nurse to determine the client's understanding of the disease. The remaining options are appropriate questions but are not important initially.

A nurse is checking a client for the correct placement of a nasogastric (NG) tube. The nurse aspirates the client's stomach contents and checks their pH level. Which of the following pH values indicates the correct placement of the tube?

4.0 Rationale: If the NG tube is in the stomach, the pH of the contents will be acidic.

An adult client with hepatic encephalopathy has a serum ammonia level of 120 mcg/dL and receives treatment with lactulose (Chronulac) syrup. The nurse determines that the client has the best and most optimal response if the level changes to which of the following after medication administration?

70 mcg/dL Rationale: The normal serum ammonia level is 10 to 80 mcg/dL. In the client with hepatic encephalopathy, the serum level is not likely to drop below normal. The most optimal yet realistic change from the options provided would be to 70 mcg/dL, which falls in the normal range. A level of 100 mcg/dL represents an insufficient effect of the medication. Lactulose is administered for its hyperosmotic laxative effect, thus removing ammonia from the colon. The client should also be monitored for hypokalemia resulting from the severe purging lactulose causes.

A nurse has been reinforcing dietary teaching for a client with peptic ulcer disease who has a routine follow-up visit. Which behavior is the best indicator of a successful outcome for this client?

A decrease in sour eructation Rationale: A decrease in sour eructation (burping) represents a change in the client's health status and is an effective indicator of a successful outcome.

A nurse is reviewing the prescriptions of a client admitted to the hospital with a diagnosis of acute pancreatitis. Choose the interventions that the nurse would expect to be prescribed for the client. Select all that apply.

Administer antacids, as prescribed. Encourage coughing and deep breathing. Administer anticholinergics, as prescribed. Rationale: The client with acute pancreatitis is normally placed on an NPO status to rest the pancreas and suppress gastrointestinal (GI) secretions. Because abdominal pain is a prominent symptom of pancreatitis, pain medication will be prescribed. Some clients experience lessened pain by assuming positions that flex the trunk and draw the knees up to the chest. A side-lying position with the head elevated 45 degrees decreases tension on the abdomen and may also help ease the pain. The client is susceptible to respiratory infections because the retroperitoneal fluid raises the diaphragm, which causes the client to take shallow, guarded abdominal breaths. Therefore measures such as turning, coughing, and deep breathing are instituted. Antacids and anticholinergics may be prescribed to suppress GI secretions.

A nurse is preparing to administer an enema to an adult client. Choose the interventions that the nurse would perform for this procedure. Select all that apply.

Apply disposable gloves. Lubricate the enema tube and insert it approximately 4 inches. Clamp the tubing if the client expresses discomfort during the procedure. Ensure that the temperature of the solution is between 100° F (37.8° C) and 105° F (40.5° C). Rationale: The administration of an enema is a clean procedure, and standard precautions must be used. The nurse applies disposable gloves when administering an enema to prevent the transfer of microorganisms. To administer an enema, the nurse places the client in the left Sims' position because the enema solution will flow downward by gravity along the natural curve of the sigmoid colon and rectum, improving retention of the enema solution. The tube is lubricated for easy insertion and is inserted approximately 3 to 4 inches in an adult. If the client complains of cramping or discomfort during the procedure, the nurse clamps the tubing until the discomfort subsides. The container containing the enema solution is hung about 12 to 18 inches above the client's anus. A flow of solution that is too forceful can damage the bowel. The temperature of the solution should be between 100° F (37.8° C) and 105° F (40.5° C). Solution that is too hot will burn the client, and solution that is too cool will cause cramping.

A client who has undergone a colostomy several days ago is reluctant to leave the hospital and has not yet looked at the ostomy site. Which measures are most likely to promote coping? Select all that apply.

Ask a member of the local ostomy club to visit with the client before discharge. Ask the enterostomal nurse specialist to consult with the client before discharge. Ask the client to begin doing one part of the ostomy care and increase tasks daily. Rationale: A member of the local ostomy club will be able to provide realistic encouragement. The enterostomal nurse specialist will be able to provide helpful information to the client. Asking the client to assist with tasks may encourage the client to take on more advanced skills and become more adjusted to the ostomy. Reminding the client about the responsibility for caring for the colostomy and telling the client that infection is a major complication (which is incorrect) will alarm the client.

A client will undergo a barium swallow to confirm a diagnosis of a hiatal hernia. In preparation for the test, the nurse instructs the client to:

Avoid eating or drinking after midnight before the test. Rationale: The stomach should be empty at the time of a barium swallow because food and medications can interfere with test results. Smoking increases mucus and acid production and can interfere with the test. For this reason, all foods, liquids, medication, and smoking are avoided before the test.

The nurse observes that a client with a nasogastric tube connected to continuous gastric suction is mouth breathing, has dry mucous membranes, and has a foul breath odor. In planning care, which nursing intervention would be best to maintain the integrity of this client's oral mucosa?

Brush the client's teeth frequently. Use diluted mouthwash and water to rinse the mouth. Rationale: After the nasogastric tube is in place, mouth care is extremely important. With one naris occluded, the client tends to mouth breathe, drying the mucous membranes. Frequent oral hygiene may be required to prevent or care for dry, irritated mucous membranes. Frequent small sips of water would be contraindicated when the client is on gastric suction. The hard candy would increase the salivation but would not be useful in cleaning the oral cavity. Lemon glycerin swabs have a drying or irritating effect on the mucous membranes.

A client has undergone esophagogastroduodenoscopy (EGD). The nurse places highest priority on which of the following items as part of the client's care plan?

Checking for return of a gag reflex Rationale: The nurse places highest priority on managing the client's airway. This includes assessing for return of the gag reflex. The client's vital signs are also monitored, and a sudden sharp increase in temperature could indicate perforation of the gastrointestinal (GI) tract. This would be accompanied by other signs as well, such as pain. Monitoring for sore throat and heartburn are also important; however, the client's airway still takes priority.

What is cholecystitis? What causes cholecystitis? Signs-

Cholecystitis is inflammation of the gallbladder, a small organ near the liver that plays a part in digesting food. Normally, fluid called bile passes out of the gallbladder on its way to the small intestine. If the flow of bile is blocked, it builds up inside the gallbladder, causing swelling, pain, and possible infection. A gallstone stuck in the cystic duct camera, a tube that carries bile from the gallbladder, is most often the cause of sudden (acute) cholecystitis. The gallstone blocks fluid from passing out of the gallbladder. This results in an irritated and swollen gallbladder. Infection or trauma, such as an injury from a car accident, can also cause cholecystitis. -Nausea or vomiting. -Tenderness in the right abdomen. -Fever. -Pain that gets worse during a deep breath. -Pain for more than 6 hours, particularly after meals.

A health care provider places a Miller-Abbott tube in a client who has a bowel obstruction. Six hours later, the nurse measures the length of the tube outside of the nares and notes that the tube has advanced 6 cm since it was first placed. Based on this finding, which action should the nurse take next?

Document the finding in the client's record. Rationale: The Miller-Abbott tube is a nasoenteric tube, which is used to decompress the intestine and correct a bowel obstruction. Initial insertion of the tube is a health care provider's responsibility. The tube is weighted by a special substance and either advances by gravity or may be advanced manually. Advancement of the tube can be monitored by measuring the tube and by taking serial x-rays.

A nurse is collecting admission data on the client with hepatitis. Which of the following findings would be a direct result of this client's condition?

Drowsiness Rationale: Hepatitis impairs liver function. If the liver is unable to perform its metabolic and detoxification functions, waste products begin to accumulate in the body. Many of those wastes are protein by-products, especially ammonia, which are harmful to the central nervous system. Increased ammonia levels are the primary cause of the neurological changes seen in liver disease, beginning first with drowsiness. The remaining options are not directly related to hepatitis.

A nurse is reinforcing dietary instructions to a client with peptic ulcer disease. The nurse encourages the client to:

Eat anything as long as it does not aggravate or cause pain. Rationale: The client may eat foods as long as they do not aggravate or cause pain. Increased GI motility should be avoided. A traditional bland diet is no longer recommended. It is unnecessary for the client to eat six small meals per day with this disorder, although smaller meals are better managed by the client.

A nurse is assigned to care for a client with a Sengstaken-Blakemore tube. The nurse should suspect that the client has which diagnosis?

Esophageal varices Rationale: A Sengstaken-Blakemore tube is inserted in a client with a diagnosis of cirrhosis with ruptured esophageal varices when other measures used to treat the varices are unsuccessful or contraindicated for the client. The tube has an esophageal and a gastric balloon. The esophageal balloon exerts pressure on the ruptured esophageal varices and stops the bleeding. The gastric balloon holds the tube in the correct position and prevents migration of the esophageal balloon, which could harm the client. This tube is not used to treat the conditions noted in the remaining options.

Before administering an intermittent tube feeding through a nasogastric tube, the nurse checks for gastric residual volume. The nurse understands that the rationale for checking gastric residual volume before administering the tube feeding is to:

Evaluate absorption of the last feeding. Rationale: All the stomach contents are aspirated and measured before administering a tube feeding. This procedure measures the gastric residual volume. The gastric residual volume is checked to confirm whether undigested formula from a previous feeding remains, and thereby evaluates the absorption of the last feeding. It is important to check the gastric residual before administration of a tube feeding. A full stomach could result in overdistention, thus predisposing the client to regurgitation and possible aspiration. If residual feeding is obtained, the health care provider's prescription and agency policy are checked to determine the course of action (hold or reduce the volume of the intermittent tube feeding).

A client is admitted to the hospital with acute viral hepatitis. Which signs or symptoms would the nurse expect to note, based upon this diagnosis?

Fatigue Rationale: Common signs of acute viral hepatitis include weight loss, dark urine, and fatigue. The client is anorexic and finds food distasteful. The urine darkens because of excess bilirubin being excreted by the kidneys. Fatigue occurs during all phases of hepatitis. Spider angiomas—small, dilated blood vessels—are commonly seen in cirrhosis of the liver.

A nurse has been caring for a client with a Sengstaken-Blakemore tube. The health care provider arrives on the nursing unit and deflates the esophageal balloon. Following deflation of the balloon, the nurse should monitor the client most closely for which of the following?

Hematemesis Rationale: A Sengstaken-Blakemore tube is inserted in a client with a diagnosis of cirrhosis with ruptured esophageal varices when other measures used to treat the varices are unsuccessful or contraindicated for the client. The esophageal balloon exerts pressure on the ruptured esophageal varices and stops the bleeding. The pressure of the esophageal balloon is released at intervals to decrease the risk of trauma to esophageal tissues, including esophageal rupture or necrosis. When the balloon is deflated the client may begin to bleed again from the esophageal varices, noted by vomiting of blood (hematemesis).

After the deflation of the balloon of a client's Sengstaken-Blakemore tube, the nurse monitors the client closely for which esophageal complication?

Hemorrhage Rationale: A Sengstaken-Blakemore tube is inserted in cirrhotic clients with ruptured esophageal varices when other measures are ineffective. The esophageal balloon exerts pressure on the ruptured esophageal varices and stops the bleeding. The pressure of esophageal balloon is released at intervals to decrease the risk of trauma to the esophageal tissues, including esophageal rupture or necrosis. When the balloon is deflated, the client may begin to bleed again from the exiting esophageal varices.

It has been determined that a client with hepatitis has contracted the infection from contaminated food. What type of hepatitis is this client most likely experiencing?

Hepatitis A Rationale: Hepatitis A is transmitted by the fecal-oral route via contaminated food or infected food handlers. Hepatitis B, C, and D are most commonly transmitted via infected blood or body fluids.

Of the following infection control methods, which would be the priority to include in the plan of care to specifically prevent hepatitis B in a client considered to be at high risk for exposure?

Hepatitis B vaccine Rationale: Immunization is the most effective method of preventing hepatitis B infection. Other general measures include handwashing. Immune globulin is used to prevent hepatitis A and is used for prophylaxis if the client is traveling to endemic areas. Personal hygiene, such as handwashing after a bowel movement and before eating, also helps prevent the transmission of hepatitis A.

A nurse is assisting with the insertion of a nasogastric tube into a client. The nurse places the client in which position for insertion?

High Fowler's position Rationale: During the insertion of a nasogastric tube, the client is placed in a sitting or high Fowler's position to reduce the risk of pulmonary aspiration if the client should vomit.

A client has asymptomatic diverticular disease. What type of diet should the nurse anticipate to be prescribed?

High-fiber diet Rationale: A high-fiber diet is the diet of choice for asymptomatic diverticular disease to help prevent straining from constipation. A high-iron diet is for clients with anemia to help make hemoglobin. A low-purine diet is for clients with gout to prevent formation of stones and crystals. Hypertensive clients and clients with cardiac problems may require a low-sodium diet to prevent increased fluid volume.

A client complains of stomach pain 30 minutes to 1 hour after eating. The pain is not relieved by further intake of food, although it is relieved by vomiting. A gastric ulcer is suspected. Which of the following data would further support this diagnosis?

History of alcohol use, smoking, and weight loss Rationale: Alcohol use, smoking, and weight loss are most commonly associated with gastric ulcers.

A nurse is collecting data on a client with a diagnosis of peptic ulcer disease. Which of the following is least likely associated with this disease?

History of the use of acetaminophen (Tylenol) for pain and discomfort Rationale: Unlike aspirin (acetylsalicylic acid, ASA), acetaminophen has little effect on platelet function, doesn't affect bleeding time, and generally produces no gastric bleeding. All associated with peptic ulcers -History of tarry black stools -History of alcohol abuse -History of gastric pain 2 to 4 hours after meals

A nurse is preparing to administer an intermittent tube feeding to a client with a nasogastric tube. The nurse checks the residual and obtains an amount of 200 mL. The nurse would:

Hold the feeding. Rationale: When 200 mL of residual formula are obtained, the feeding is held and the health care provider (HCP) is notified, because this is an indication that the feeding is not being absorbed. If the residual is less than 100 mL, the feeding is usually administered. Large-volume aspirates indicate delayed gastric emptying and place the client at risk for aspiration. Always check the HCP's prescriptions and agency policy regarding residual amounts.

A nurse is caring for a client with acute pancreatitis and a history of alcoholism and is monitoring the client for complications. Which of the following data would be a sign of paralytic ileus?

Inability to pass flatus Rationale: An inflammatory reaction, such as acute pancreatitis, can cause paralytic ileus, the most common form of nonmechanical obstruction. Inability to pass flatus is a clinical manifestation of paralytic ileus. Option 4 is the description of the physical finding of liver enlargement. The liver is usually enlarged in cases of cirrhosis or hepatitis. Although this client may have an enlarged liver, it is not a sign of paralytic ileus or intestinal obstruction. Pain is associated with paralytic ileus, but the pain usually presents as a more constant generalized discomfort. Pain that is severe, constant, and rapid in onset is more likely caused by strangulation of the bowel. Loss of sphincter control is not a sign of paralytic ileus.

A client is admitted to the hospital with viral hepatitis and is complaining of a loss of appetite. In order to provide adequate nutrition, the nurse encourages the client to:

Increase intake of fluids. Rationale: Although no special diet is required in the treatment of viral hepatitis, it is generally recommended that clients have a diet with low-fat content, because fat may be poorly tolerated due to decreased bile production. Small, frequent meals are preferable and may even prevent nausea. Often times, the appetite is better in the morning, so it is easier to eat a healthy breakfast. An adequate fluid intake of 2500 to 3000 mL/day that includes nutritional fluids is also important.

A nurse is caring for a client after a Billroth II procedure. On review of the postoperative prescriptions, which of the following, if prescribed, would the nurse question and verify?

Irrigating the nasogastric (NG) tube Rationale: In a Billroth II resection, 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, however, should never irrigate or reposition the gastric tube after gastric surgery unless specifically prescribed by the health care provider.

A nurse is assisting in planning stress management strategies for the client with irritable bowel syndrome. Which suggestion would the nurse give to the client?

Learn measures such as biofeedback or progressive relaxation. Rationale: Treatment for irritable bowel syndrome includes stress reduction measures such as biofeedback, progressive relaxation, and regular exercise. The client should also learn to limit responsibilities. Other measures include increased fluid and fiber in the diet as prescribed and antispasmodic or sedative medications as needed.

A nurse would include which of the following when reinforcing home care instructions for a client who has peptic ulcer disease?

Learn to use stress reduction techniques. Rationale: Identifying and reducing stress is essential to a comprehensive ulcer management plan. The client should also avoid intake of foods that aggravate pain, quit smoking, and avoid irritants such as NSAIDs. Antibiotic therapy often cures the client of this problem in many instances.

A nurse is administering a cleansing enema to a client with a fecal impaction. Before administering the enema, the nurse assists the client to which of the following positions?

Left Sims' position Rationale: When administering an enema, the client is placed in a left Sims' position so that the enema solution can flow by gravity in the natural direction of the colon. The head of the bed is not elevated.

A nurse provides instructions to a client after a liver biopsy. The nurse tells the client to:

Lie on the right side for 2 hours. To splint the puncture site, the client is kept on his or her right side for a minimum of 2 hours.

The nurse is providing discharge instructions to a client after gastrectomy. Which measure will the nurse instruct the client to follow to help prevent dumping syndrome?

Limit the fluids taken with meals. Rationale: The client should be instructed to decrease the amount of fluid taken at meals. The client should also be instructed to avoid high-carbohydrate foods including fluids, such as fruit nectars; assume a low-Fowler's position during meals; lie down for 30 minutes after eating to delay gastric emptying; and take antispasmodics as prescribed.

A client has been diagnosed with acute gastroenteritis. Which of the following diets should the nurse anticipate would be prescribed for the client?

Low fiber Rationale: A low-fiber diet places less strain on the intestines because this type of diet is easier to digest. This diet is prescribed for clients with inflammatory bowel disease, ileostomy, colostomy, partial obstructions of the intestinal tract, acute gastroenteritis, or diarrhea.

A client with acute pancreatitis is experiencing severe pain from the disorder. The nurse tells the client to avoid which position that could aggravate the pain?

Lying flat Rationale: Positions such as sitting up, leaning forward, and flexing the legs (especially the left leg) may alleviate some of the pain associated with pancreatitis. The pain is aggravated by lying supine or walking. This is because the pancreas is located retroperitoneally, and the edema and inflammation intensify the irritation of the posterior peritoneal wall with these positions.

A client with hiatal hernia chronically experiences heartburn after meals. The nurse would teach the client to avoid which of the following, which is contraindicated with hiatal hernia?

Lying recumbent after meals Rationale: Hiatal hernia is caused by a protrusion of a portion of the stomach above the diaphragm, where the esophagus usually is positioned. The client generally experiences pain caused by reflux resulting from ingestion of irritating foods, lying flat following meals or at night, and consuming large or fatty meals. Relief is obtained by eating small, frequent, and bland meals; histamine antagonists and antacids; and elevation of the thorax after meals and during sleep.

A client has just undergone a gastroscopy. Which action should be taken by the nurse as the essential post-procedure nursing intervention?

Monitoring for the gag reflex Rationale: To prevent aspiration, the client may not eat or drink after this procedure until protective airway reflexes return. The nurse must document that the gag and swallow reflexes have returned. The client would receive a local anesthetic to the throat before the procedure, not after. Positioning restrictions are not necessary following the procedure.

A nurse planning care for a client with hepatitis plans to meet the client's safety needs by:

Monitoring prothrombin and partial thromboplastin values Rationale: When liver function is impaired, as in the client with hepatitis, some important body functions do not occur. The liver synthesizes fibrinogen, prothrombin, and factors needed for normal blood clotting. Without those clotting ingredients, bleeding may occur either internally or externally. Monitoring coagulation studies provides the nurse with information needed to plan ways to reduce the risk of hemorrhage when providing care. Daily weight is often part of a nursing care plan but is more related to fluid balance than safety; monitoring weight twice daily would not be necessary. Tepid baths may decrease the pruritus associated with jaundice, but this is not a safety issue either.

Treatment measures have been implemented for a client with bleeding esophageal varices and have been unsuccessful. The health care provider states that a Sengstaken-Blakemore tube will be used to control the resulting hemorrhage. The nurse prepares for insertion via which of the following routes?

Nasogastric A Sengstaken-Blakemore tube is inserted via the nose into the esophagus and stomach.

A nurse is caring for a client suspected of having appendicitis. Which of the following would the nurse anticipate will be prescribed for this client?

No oral intake of liquids or food Rationale: For the client with suspected or known appendicitis, the nurse should ensure the client remains on nothing by mouth status in anticipation of emergency surgery and also to avoid worsening the inflammation.

A client who has been prescribed indomethacin (Indocin) for gout is asked to provide a stool sample for guaiac testing. The nurse explains that the purpose of the test is to determine:

Occult blood Rationale: Indomethacin is a nonsteroidal anti-inflammatory medication that can cause gastrointestinal irritation. The stool guaiac test is noninvasive and is widely used as a gross screening for blood in the gastrointestinal tract. It is not used for any of the other reasons listed.

A client with viral hepatitis has no appetite, and food makes the client nauseated. Which nursing intervention would be appropriate?

Offer small, frequent meals. Rationale: If nausea persists, the client will need to be assessed for fluid and electrolyte imbalances. It is important to explain to the client that the majority of calories should be eaten in the morning hours, because nausea most often occurs in the afternoon and evening. Clients should select a diet high in calories, because energy is required for healing. Changes in bilirubin interfere with fat absorption, so low-fat diets are better tolerated.

A nurse is participating in a health screening clinic and is preparing teaching materials about colorectal cancer. The nurse would plan to include which risk factor for colorectal cancer in the material?

Personal history of ulcerative colitis or gastrointestinal (GI) polyps Rationale: Common risk factors for colorectal cancer include age over 40 years; first-degree relative with colorectal cancer; high-fat, low-fiber diet; and history of bowel problems such as ulcerative colitis or familial polyposis.

A nurse is reviewing the health care provider's prescriptions written for a client admitted with acute pancreatitis. Which health care provider prescription would the nurse verify if noted on the client's chart?

Position the client supine and flat. Rationale: The pain associated with acute pancreatitis is aggravated when the client lies in a supine and flat position. Therefore, the nurse would verify this prescription.

A client with peptic ulcer disease has been prescribed misoprostol (Cytotec) and sucralfate (Carafate). The nurse teaches the client that these two medications will work primarily to:

Protect the gastric mucosa. Rationale: Both of these medications protect the stomach lining. Misoprostol increases mucus production and bicarbonate levels, although sucralfate coats the ulcer surface.

A nurse is monitoring for stoma prolapse in a client with a colostomy. The nurse would observe which of the following appearances in the stoma if prolapse occurred?

Protruding and swollen Rationale: A prolapsed stoma is one in which bowel protrudes through the stoma, with an elongated and swollen appearance. A stoma retraction is characterized by sinking of the stoma. Ischemia of the stoma would be associated with dusky or bluish color. A stoma with a narrowed opening, either at the level of the skin or fascia, is said to be stenosed.

A nurse is collecting data on a client admitted to the hospital with hepatitis. Which data would indicate that the client may have liver damage?

Pruritus Rationale: Significant damage to liver cells renders them unable to metabolize bilirubin. When a red blood cell is broken down, hemoglobin is released. The heme portion is catabolized into unconjugated bilirubin. The liver then takes that unconjugated bilirubin and transforms it into conjugated bilirubin that passes into the hepatic ducts and eventually into the bowel, providing the normal brown color to stool. When bilirubin is not metabolized by the liver, it accumulates in the circulation and is minimally excreted by the skin, causing jaundice and pruritus. It is also eliminated unchanged by the kidneys, causing urine to become dark amber or brown.

A client is admitted to the hospital with a bowel obstruction secondary to a recurrent malignancy, and the health care provider plans to insert a Miller-Abbott tube. When the nurse tries to explain the procedure, the client interrupts the nurse and states, "I don't want to hear about that. Just let the doctor do it." Based on the client's statement, the nurse determines that the best action is to:

Remain with the client and be silent. Rationale: The nurse needs to recognize that the client has a greater need for security and acceptance than education. In option 4, the nurse conveys acceptance of the client and uses the therapeutic communication technique of silence.

An ultrasound of the gallbladder is scheduled for the client with a suspected diagnosis of cholecystitis. The nurse explains to the client that this test:

Requires the client to lie still for short intervals Rationale: Ultrasound of the gallbladder is a noninvasive procedure and is frequently used for emergency diagnosis of acute cholecystitis. The client does not need to be NPO, but may be instructed to avoid carbonated beverages for 48 hours before the test to help decrease intestinal gas. It is a painless test and does not require the administration of oral tablets as preparation

A nurse has given the client with hepatitis instructions about postdischarge management during convalescence. The nurse determines that the client needs further teaching if the client states to:

Resume full activity level within 1 week. Rationale: The client with hepatitis is easily fatigued and may require several weeks to resume full activity level. It is important for the client to get adequate rest so that the liver may heal. The client should take in a high-carbohydrate and low-fat diet. The client should avoid hepatotoxic substances, such as aspirin and alcohol. If prescribed for prolonged clotting times, the client should take vitamin K.

A client who has undergone a subtotal gastrectomy is being prepared for discharge. Which item concerning ongoing self-management should the nurse reinforce to the client?

Smaller and more frequent meals should be eat Rationale: Following gastric surgery, the client should eat smaller, more frequent meals to facilitate digestion. The client should resume activity gradually and should minimize stressors to prevent recurrence of symptoms. The client requires ongoing medical supervision and evaluation.

A nurse is reviewing the health care record of a client with a diagnosis of chronic pancreatitis. Which data noted in the record indicate poor absorption of dietary fats?

Steatorrhea Rationale: The pancreas makes digestive enzymes that aid absorption. Chronic pancreatitis interferes with the absorption of nutrients. Fat absorption is limited because of the lack of pancreatic lipase. Steatorrhea by definition is excess fat in stools often caused by malabsorption problems.

A nurse is monitoring a client for the early signs and symptoms of dumping syndrome. Which of the following symptoms indicate this occurrence?

Sweating and pallor Rationale: Early manifestations occur 5 to 30 minutes after eating. Symptoms include vertigo, tachycardia, syncope, sweating, pallor, palpitations, and the desire to lie down.

A licensed practical nurse (LPN) is preparing to assist a registered nurse (RN) with removing a nasogastric (NG) tube from the client. The LPN would instruct the client to do which of the following?

Take and hold a deep breath. Rationale: When the RN removes the NG tube, the client is instructed to take and hold a deep breath. This will close the epiglottis, and the airway will be temporarily obstructed during the tube removal. This allows for the easy withdrawal of the tube through the esophagus into the nose. The RN removes the tube with one very smooth, continuous pull.

A client had a Miller-Abbott tube inserted 24 hours ago. The nurse is asked to check the client to determine whether the tube is in the appropriate location at this time. Which of the following findings would indicate adequate location of the tube?

The aspirate from the tube has a pH of 7.45. Rationale: The Miller-Abbott tube is a nasoenteric tube that is used to decompress the intestine (to correct a bowel obstruction). The end of the tube should be located in the intestine. The pH of the gastric fluid is acidic, and the pH of the intestinal fluid is 7 or higher if the tube is adequately located. Location of the tube can also be determined by x-ray, not palpation

A nurse provides medication instructions to a client with peptic ulcer disease. Which statement by the client indicates the best understanding of the medication therapy?

The nizatidine (Axid) will cause me to produce less stomach acid." Rationale: Nizatidine, a histamine H2-receptor blocker, is frequently used in the management of peptic ulcer disease. Histamine H2-receptor blockers decrease the secretion of gastric acid (HCL). Antacids are used as adjunct therapy and neutralize acid in the stomach. Omeprazole is a proton pump inhibitor.
