-Chronic diarrhea/vomiting -Surgery/trauma -Gastrointestinal obstruction -Severe anorexia nervosa -Severe malabsorption -Short bowel syndrome

Treatment for gastritis includes

-Limiting alcohol/drugs -Treatment of H pylori virus -B12 injections/nasal spray

Symptoms of dumping syndrome include?

-Vomiting -Nausea -Weakness -Sweating -Fainting

When is PPN used?

1. Nutritional support is needed only for a short time 2. Protein and caloric requirements are not high 3. The risk of a central catheter is too great 4. PN is used to supplement inadequate oral intake

After vertical banded gastroplasty, a 42-year-old male patient returns to the surgical nursing unit with a nasogastric tube to low, intermittent suction and a patient-controlled analgesia (PCA) machine for pain control. Which nursing action should be included in the postoperative plan of care? a. Offer sips of fruit juices at frequent intervals. b. Irrigate the nasogastric (NG) tube frequently. c. Remind the patient that PCA use may slow the return of bowel function. d. Support the surgical incision during patient coughing and turning in bed.

ANS: D The incision should be protected from strain to decrease the risk for wound dehiscence. The patient should be encouraged to use the PCA because pain control will improve the cough effort and patient mobility. NG irrigation may damage the suture line or overfill the stomach pouch. Sugar-free clear liquids are offered during the immediate postoperative time to decrease the risk for dumping syndrome.

A client receives a local anesthetic to suppress the gag reflex for a diagnostic procedure of the upper GI tract. Which of the following nursing interventions is advised for this patient? a) The client should be monitored for any breathing related disorder or discomforts b) The client should not be given any food and fluids until the gag reflex returns c) The client should be monitored for cramping or abdominal distention d) The client's fluid output should be measured for at least 24 hours after the procedure

B) The client should not be given any food and fluids until the gag reflex returns. For a client receiving a local anesthetic that suppresses the gag reflex, the nurse is advised to withhold food and fluids until the reflex returns.

The nurse is caring for a 47-year-old female patient who is comatose and is receiving continuous enteral nutrition through a soft nasogastric tube. The nurse notes the presence of new crackles in the patient's lungs. In which order will the nurse take action? (Put a comma and a space between each answer choice [A, B, C, D].) a. Check the patient's oxygen saturation. b. Notify the patient's health care provider. c. Measure the tube feeding residual volume. d. Stop administering the continuous feeding

D, A, C, B The assessment data indicate that aspiration may have occurred, and the nurse's first action should be to turn off the tube feeding to avoid further aspiration. The next action should be to check the oxygen saturation because this may indicate the need for immediate respiratory suctioning or oxygen administration. The residual volume should be obtained because it provides data about possible causes of aspiration. Finally, the health care provider should be notified and informed of all the assessment data the nurse has just obtained.

The nurse evaluates laboratory findings for a client hospitalized because of chronic obstructive pulmonary disease. Which finding is consistent with poor nutrition? A. Nitrogen balance of 3 g B. Transferrin level of 370 mg/dl C. Hemoglobin level of 13.8 D. Serum albumin level of 2.5 g/dl

D. Serum albumin level of 2.5 g/dl

If a pt is having pain 2-4 hrs after meals and midmorning, mindafternoon, middle of night pain, what type of ulcer may they have?

Duodenal ulcers

If a pt is having pain 1-2 hrs after meals, what type of ulcer may they have?

Gastric ulcer

How should a pt with GERD be positioned following a meal?

HOB elevated 30 degrees for 2-3 hours on 4-6 inch blocks

What information should be taught to pt about diet post op-bariatric surgery?

High in protein -Low in carbs/fat/roughage -6 small meals -DO NOT INGEST FLUIDS WITH THE MEAL

What are the two most common and effective treatments for symptomatic GERD?

PPIs-...ZOLE's H2-receptor blockers-...DINE's

Treating pt with perforation

VS q15 min Stop all oral/NG drugs and feedings until physician notified Maintain IV fluids Antibiotic therapy after perforation is confirmed

When obtaining a nursing history on a client with a suspected gastric ulcer, which signs and symptoms should the nurse expect to assess? Select all that apply. 1. Epigastric pain at night. 2. Relief of epigastric pain after eating. 3. Vomiting. 4. Weight loss. 5. Melena.

3, 4, 5. Vomiting and weight loss are common with gastric ulcers. The client may also have blood in the stools (melena) from gastric bleeding. Clients with a gastric ulcer are most likely to complain of a burning epigastric pain that occurs about 1 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.

Cimetidine (Tagamet) may also be used to treat hiatal hernia. The nurse should understand that this drug is used to prevent which of the following? 1. Esophageal reflux. 2. Dysphagia. 3. Esophagitis. 4. Ulcer formation.

3. Cimetidine (Tagamet) is a histamine receptor antagonist that decreases the quantity of gastric secretions. It may be used in hiatal hernia therapy to prevent or treat the esophagitis and heartburn associated with reflux. Cimetidine is not used to prevent reflux, dysphagia, or ulcer development.

What is the main complication of Roux-en-Y gastric bypass surgery?

Dumping syndrome

Would you want your patient to ambulate or maintain bed rest 2 days after bariatric surgery?

Early ambulation is essential

Patients are discouraged from eating what types of foods after bypass surgery to avoid dumping syndrome?

Sugary foods

The nurse is caring for a client who has had a gastroscopy. Which of the following signs and symptoms may indicate that the client is developing a complication related to the procedure? Select all that apply. 1. The client has a sore throat. 2. The client has a temperature of 100 ° F (37.8 ° C). 3. The client appears drowsy following the procedure. 4. The client has epigastric pain. 5. The client experiences hematemesis.

2, 4, 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.

The nurse is preparing to teach a client with a peptic ulcer about the diet that should be followed after discharge. The nurse should explain that the diet will most likely consist of which of the following? 1. Bland foods. 2. High-protein foods. 3. Any foods that are tolerated. 4. Large amounts of milk.

3. Diet therapy for ulcer disease is a controversial issue. There is no scientific evidence that diet therapy promotes healing. Most clients are instructed to follow a diet that they can tolerate. There is no need for the client to ingest only a bland or high-protein diet. Milk may be included in the diet, but it is not recommended in excessive amounts.

A client is to take one daily dose of ranitidine (Zantac) at home to treat her peptic ulcer. The client understands proper drug administration of ranitidine when she says that she will take the drug at which of the following times? 1. Before meals. 2. With meals. 3. At bedtime. 4. When pain occurs.

3. 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. It is not necessary to take the drug before meals. The client should take the drug regularly, not just when pain occurs.

A client who has been diagnosed with gastroesophageal reflux disease (GERD) complains of heartburn. To decrease the heartburn, the nurse should instruct the client to eliminate which of the following items from the diet? 1. Lean beef. 2. Air-popped popcorn. 3. Hot chocolate. 4. Raw vegetables.

3. With GERD, eating substances that decrease lower esophageal sphincter pressure causes heartburn. A decrease in the lower esophageal sphincter pressure allows gastric contents to reflux into the lower end of the esophagus. Foods that can cause a decrease in esophageal sphincter pressure include fatty foods, chocolate, caffeinated beverages, peppermint, and alcohol. A diet high in protein and low in fat is recommended for clients with GERD. Lean beef, popcorn, and raw vegetables would be acceptable.

The client with gastroesophageal reflux disease (GERD) complains of a chronic cough. The nurse understands that in a client with GERD this symptom may be indicative of which of the following conditions? 1. Development of laryngeal cancer. 2. Irritation of the esophagus. 3. Esophageal scar tissue formation. 4. Aspiration of gastric contents.

4. 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.

A client with peptic ulcer disease is taking ranitidine (Zantac). What is the expected outcome of this drug? 1. Heal the ulcer. 2. Protect the ulcer surface from acids. 3. Reduce acid concentration. 4. Limit gastric acid secretion.

4. Histamine-2 (H2) receptor antagonists, such as ranitidine, reduce gastric acid secretion. Antisecretory, or proton-pump inhibitors, such as omeprazole (Prilosec), help ulcers heal quickly in 4 to 8 weeks. Cytoprotective drugs, such as sucralfate (Carafate), protect the ulcer surface against acid, bile, and pepsin. Antacids reduce acid concentration and help reduce symptoms.

The client attends two sessions with the dietitian to learn about diet modifications to minimize gastroesophageal reflux. The teaching would be considered successful if the client says that she will decrease her intake of which of the following foods? 1. Fats. 2. High-sodium foods. 3. Carbohydrates. 4. High-calcium foods.

1. Fats are associated with decreased esophageal sphincter tone, which increases reflux. Obesity contributes to the development of hiatal hernia, and a low-fat diet might also aid in weight loss. Carbohydrates and foods high in sodium or calcium do not affect gastroesophageal reflux.

The nurse instructs the client on health maintenance activities to help control symptoms from her hiatal hernia. Which of the following statements would indicate that the client has understood the instructions? 1. "I'll avoid lying down after a meal." 2. "I can still enjoy my potato chips and cola at bedtime." 3. "I wish I didn't have to give up swimming." 4. "If I wear a girdle, I'll have more support for my stomach."

1. A client with a hiatal hernia should avoid the recumbent position immediately after meals to minimize gastric reflux. Bedtime snacks, as well as high-fat foods and carbonated beverages, should be avoided. Excessive vigorous exercise also should be avoided, especially after meals, but there is no reason why the client must give up swimming. Wearing tight, constrictive clothing such as a girdle can increase intra-abdominal pressure and thus lead to reflux of gastric juices.

The client is scheduled to have an upper gastrointestinal tract series of x-rays. Following the x-rays, the nurse should instruct the client to: 1. Take a laxative. 2. Follow a clear liquid diet. 3. Administer an enema. 4. Take an antiemetic.

1. The client should take a laxative after an upper gastrointestinal series to stimulate a bowel movement. This examination involves the administration of barium, which must be promptly eliminated from the body because it may harden and cause an obstruction. A clear liquid diet would have no effect on stimulating removal of the barium. The client should not have nausea and an antiemetic would not be necessary; additionally, the antiemetic will decrease peristalsis and increase the likelihood of eliminating the barium. An enema would be ineffective because the barium is too high in the gastrointestinal tract.

The nurse is caring for a client who has just had an upper GI endoscopy. The client's vital signs must be taken every 30 minutes for 2 hours after the procedure. The nurse assigns an unlicensed nursing personnel (UAP) to take the vital signs. One hour later, the UAP reports the client, who was previously afebrile, has developed a temperature of 101.8 ° F (38.8 ° C). What should the nurse do in response to this reported assessment data? 1. Promptly assess the client for potential perforation. 2. Tell the assistant to change thermometers and retake the temperature. 3. Plan to give the client acetaminophen (Tylenol) to lower the temperature. 4. Ask the assistant to bathe the client with tepid water.

1. A sudden spike in temperature following an endoscopic procedure may indicate perforation of the GI tract. The nurse should promptly conduct a further assessment of the client, looking for further indicators of perforation, such as a sudden onset of acute upper abdominal pain; a rigid, boardlike abdomen; and developing signs of shock. Telling the assistant to change thermometers is not an appropriate action and only further delays the appropriate action of assessing the client. The nurse would not administer acetaminophen without further assessment of the client or without a physician's order; a suspected perforation would require that the client be placed on nothing-by-mouth status. Asking the assistant to bathe the client before any assessment by the nurse is inappropriate.

Which of the following dietary measures would be useful in preventing esophageal reflux? 1. Eating small, frequent meals. 2. Increasing fluid intake. 3. Avoiding air swallowing with meals. 4. Adding a bedtime snack to the dietary plan.

1. 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.

The nurse is obtaining a health history from a client who has a sliding hiatal hernia associated with reflux. The nurse should ask the client about the presence of which of the following symptoms? 1. Heartburn. 2. Jaundice. 3. Anorexia. 4. Stomatitis.

1. Heartburn, the most common symptom of a sliding hiatal hernia, results from reflux of gastric secretions into the esophagus. Regurgitation of gastric contents and dysphagia are other common symptoms. Jaundice, which results from a high concentration of bilirubin in the blood, is not associated with hiatal hernia. Anorexia is not a typical symptom of hiatal hernia. Stomatitis is inflammation of the mouth.

The physician prescribes metoclopramide hydrochloride (Reglan) for the client with hiatal hernia. The nurse plans to instruct the client that this drug is used in hiatal hernia therapy to accomplish which of the following objectives? 1. Increase tone of the esophageal sphincter. 2. Neutralize gastric secretions. 3. Delay gastric emptying. 4. Reduce secretion of digestive juices.

1. Metoclopramide hydrochloride (Reglan) increases esophageal sphincter tone and facilitates gastric emptying; both actions reduce the incidence of reflux. Other drugs, such as antacids or histamine receptor antagonists, may also be prescribed to help control reflux and esophagitis and to decrease or neutralize gastric secretions. Reglan is not effective in decreasing or neutralizing gastric secretions.

The nurse finds a client who has been diagnosed with a peptic ulcer surrounded by papers from his briefcase and arguing on the telephone with a coworker. The nurse's response to observing these actions should be based on knowledge that: 1. Involvement with his job will keep the client from becoming bored. 2. A relaxed environment will promote ulcer healing. 3. Not keeping up with his job will increase the client's stress level. 4. Setting limits on the client's behavior is an important nursing responsibility.

2. A relaxed environment is an essential component of ulcer healing. Nurses can help clients understand the importance of relaxation and explore with them ways to balance work and family demands to promote healing. Being involved with his work may prevent boredom; however, this client is upset and argumentative. Not keeping up with his job will probably increase the client's stress level, but the nurse's response is best if it is based on the fact that a relaxed environment is an essential component of ulcer healing. Nurses cannot set limits on a client's behavior; clients must make the decision to make lifestyle changes.

Which of the following factors would most likely contribute to the development of a client's hiatal hernia? 1. Having a sedentary desk job. 2. Being 5 feet, 3 inches tall and weighing 190 lb. 3. Using laxatives frequently. 4. Being 40 years old.

2. Any factor that increases intra-abdominal pressure, such as obesity, can contribute to the development of hiatal hernia. Other factors include abdominal straining, frequent heavy lifting, and pregnancy. Hiatal hernia is also associated with older age and occurs in women more frequently than in men. Having a sedentary desk job, using laxatives frequently, or being 40 years old is not likely to be a contributing factor in development of a hiatal hernia.

Which of the following lifestyle modifications should the nurse encourage the client with a hiatal hernia to include in activities of daily living? 1. Daily aerobic exercise. 2. Eliminating smoking and alcohol use. 3. Balancing activity and rest. 4. Avoiding high-stress situations.

2. Smoking and alcohol use both reduce esophageal sphincter tone and can result in reflux. They therefore should be avoided by clients with hiatal hernia. Daily aerobic exercise, balancing activity and rest, and avoiding high-stress situations may increase the client's general health and well-being, but they are not directly associated with hiatal hernia.

Which of the following instructions should the nurse include in the teaching plan for a client who is experiencing gastroesophageal reflux disease (GERD)? 1. Limit caffeine intake to two cups of coffee per day. 2. Do not lie down for 2 hours after eating. 3. Follow a low-protein diet. 4. Take medications with milk to decrease irritation.

2. The nurse should instruct the client to not lie down for about 2 hours after eating to prevent reflux. Caffeinated beverages decrease pressure in the lower esophageal sphincter and milk increases gastric acid secretion, so these beverages should be avoided. The client is encouraged to follow a high-protein, low-fat diet, and avoid foods that are irritating.

A client has been taking aluminum hydroxide (Amphojel) 30 mL six times per day at home to treat his peptic ulcer. He tells the nurse that he has been unable to have a bowel movement for 3 days. Based on this information, the nurse would determine that which of the following is the most likely cause of the client's constipation? 1. The client has not been including enough fiber in his diet. 2. The client needs to increase his daily exercise. 3. The client is experiencing an adverse effect of the aluminum hydroxide. 4. The client has developed a gastrointestinal obstruction.

3. It is most likely that the client is experiencing an adverse 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 the constipation caused by the aluminum hydroxide. Constipation, in isolation from other symptoms, is not a sign of a bowel obstruction.

The client has been taking magnesium hydroxide (milk of magnesia) at home in an attempt to control hiatal hernia symptoms. The nurse should assess the client for which of the following conditions most commonly associated with the ongoing use of magnesium-based antacids? 1. Anorexia. 2. Weight gain. 3. Diarrhea. 4. Constipation.

3. The magnesium salts in magnesium hydroxide are related to those found in laxatives and may cause diarrhea. Aluminum salt products can cause constipation. Many clients find that a combination product is required to maintain normal bowel elimination. The use of magnesium hydroxide does not cause anorexia or weight gain.

A client is taking an antacid for treatment of a peptic ulcer. Which of the following statements best indicates that the client understands how to correctly take the antacid? 1. "I should take my antacid before I take my other medications." 2. "I need to decrease my intake of fluids so that I don't dilute the effects of my antacid." 3. "My antacid will be most effective if I take it whenever I experience stomach pains." 4. "It is best for me to take my antacid 1 to 3 hours after meals."

4. 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. If antacids are taken more frequently than recommended, the likelihood of developing adverse effects increases. Therefore, the client should not take antacids as often as desired to control pain.

A client is admitted to the hospital after vomiting bright red blood and is diagnosed with a bleeding duodenal ulcer. The client develops a sudden, sharp pain in the midepigastric region along with a rigid, boardlike abdomen. These clinical manifestations most likely indicate which of the following? 1. An intestinal obstruction has developed. 2. Additional ulcers have developed. 3. The esophagus has become inflamed. 4. The ulcer has perforated.

4. The body reacts to perforation of an ulcer by immobilizing the area as much as possible. This results in boardlike abdominal 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. The development of additional ulcers or esophageal inflammation would not cause a rigid, boardlike abdomen.

Which finding for a 19-year-old female who is a vegan may indicate the need for cobalamin supplementation? a. Paresthesias b. Ecchymoses c. Dry, scaly skin d. Gingival swelling

ANS: A Cobalamin (vitamin B12) cannot be obtained from foods of plant origin, so the patient will be most at risk for signs of cobalamin deficiency, such as paresthesias, peripheral neuropathy, and anemia. The other symptoms listed are associated with other nutritional deficiencies but would not be associated with a vegan diet.

The nurse will be teaching self-management to patients after gastric bypass surgery. Which information will the nurse plan to include? a. Drink fluids between meals but not with meals. b. Choose high-fat foods for at least 30% of intake. c. Developing flabby skin can be prevented by exercise. d. Choose foods high in fiber to promote bowel function.

ANS: A Intake of fluids with meals tends to cause dumping syndrome and diarrhea. Food choices should be low in fat and fiber. Exercise does not prevent the development of flabby skin.

The nurse determines that teaching regarding cobalamin injections has been effective when the patient with chronic atrophic gastritis states which of the following? a. "The cobalamin injections will prevent gastric inflammation." b. "The cobalamin injections will prevent me from becoming anemic." c. "These injections will increase the hydrochloric acid in my stomach." d. "These injections will decrease my risk for developing stomach cancer."

ANS: B Cobalamin supplementation prevents the development of pernicious anemia. Chronic gastritis may cause achlorhydria, but cobalamin does not correct this. The loss of intrinsic factor secretion with chronic gastritis is permanent, and the patient will need lifelong supplementation with cobalamin. The incidence of stomach cancer is higher in patients with chronic gastritis, but cobalamin does not reduce the risk for stomach cancer.

Which information will the nurse include for a patient with newly diagnosed gastroesophageal reflux disease (GERD)? a. "Peppermint tea may reduce your symptoms." b. "Keep the head of your bed elevated on blocks." c. "You should avoid eating between meals to reduce acid secretion." d. "Vigorous physical activities may increase the incidence of reflux."

ANS: B Elevating the head of the bed will reduce the incidence of reflux while the patient is sleeping. Peppermint will decrease lower esophageal sphincter (LES) pressure and increase the chance for reflux. Small, frequent meals are recommended to avoid abdominal distention. There is no need to make changes in physical activities because of GERD.

A family member of a 28-year-old patient who has suffered massive abdominal trauma in an automobile accident asks the nurse why the patient is receiving famotidine (Pepcid). The nurse will explain that the medication will a. decrease nausea and vomiting. b. inhibit development of stress ulcers. c. lower the risk for H. pylori infection. d. prevent aspiration of gastric contents.

ANS: B Famotidine is administered to prevent the development of physiologic stress ulcers, which are associated with a major physiologic insult such as massive trauma. Famotidine does not decrease nausea or vomiting, prevent aspiration, or prevent H. pylori infection.

A 26-year-old patient with a family history of stomach cancer asks the nurse about ways to decrease the risk for developing stomach cancer. The nurse will teach the patient to avoid a. emotionally stressful situations. b. smoked foods such as ham and bacon. c. foods that cause distention or bloating. d. chronic use of H2 blocking medications.

ANS: B Smoked foods such as bacon, ham, and smoked sausage increase the risk for stomach cancer. Stressful situations, abdominal distention, and use of H2 blockers are not associated with an increased incidence of stomach cancer.

Which medications will the nurse teach the patient about whose peptic ulcer disease is associated with Helicobacter pylori? a. Sucralfate (Carafate), nystatin (Mycostatin), and bismuth (Pepto-Bismol) b. Amoxicillin (Amoxil), clarithromycin (Biaxin), and omeprazole (Prilosec) c. Famotidine (Pepcid), magnesium hydroxide (Mylanta), and pantoprazole (Protonix) d. Metoclopramide (Reglan), bethanechol (Urecholine), and promethazine (Phenergan)

ANS: B The drugs used in triple drug therapy include a proton pump inhibitor such as omeprazole and the antibiotics amoxicillin and clarithromycin. The other combinations listed are not included in the protocol for H. pylori infection.

A 62- year-old man reports chronic constipation. To promote bowel evacuation, the nurse will suggest that the patient attempt defecation a. in the mid-afternoon. b. after eating breakfast. c. right after getting up in the morning. d. immediately before the first daily meal.

ANS: B The gastrocolic reflex is most active after the first daily meal. Arising in the morning, the anticipation of eating, and physical exercise do not stimulate these reflexes.

A 19-year-old female admitted with anorexia nervosa is 5 ft 6 in (163 cm) tall and weighs 88 pounds (41 kg). Laboratory tests reveal hypokalemia and iron-deficiency anemia. Which nursing diagnosis has the highest priority? a. Risk for activity intolerance related to anemia b. Risk for electrolyte imbalance related to eating patterns c. Ineffective health maintenance related to body image obsession d. Imbalanced nutrition: less than body requirements related to anorexia

ANS: B The patient's hypokalemia may lead to life-threatening cardiac dysrhythmias. The other diagnoses are also appropriate for this patient but are not associated with immediate risk for fatal complications.

A 44-year-old man admitted with a peptic ulcer has a nasogastric (NG) tube in place. When the patient develops sudden, severe upper abdominal pain, diaphoresis, and a firm abdomen, which action should the nurse take? a. Irrigate the NG tube. b. Check the vital signs. c. Give the ordered antacid. d. Elevate the foot of the bed.

ANS: B The patient's symptoms suggest acute perforation, and the nurse should assess for signs of hypovolemic shock. Irrigation of the NG tube, administration of antacids, or both would be contraindicated because any material in the stomach will increase the spillage into the peritoneal cavity. Elevating the foot of the bed may increase abdominal pressure and discomfort, as well as making it more difficult for the patient to breathe.

A 68-year-old patient with a bleeding duodenal ulcer has a nasogastric (NG) tube in place, and the health care provider orders 30 mL of aluminum hydroxide/magnesium hydroxide (Maalox) to be instilled through the tube every hour. To evaluate the effectiveness of this treatment, the nurse a. monitors arterial blood gas values daily. b. periodically aspirates and tests gastric pH. c. checks each stool for the presence of occult blood. d. measures the volume of residual stomach contents.

ANS: B The purpose for antacids is to increase gastric pH. Checking gastric pH is the most direct way of evaluating the effectiveness of the medication. Arterial blood gases may change slightly, but this does not directly reflect the effect of antacids on gastric pH. Because the patient has upper gastrointestinal (GI) bleeding, occult blood in the stools will appear even after the acute bleeding has stopped. The amount of residual stomach contents is not a reflection of resolution of bleeding or of gastric pH.

Which information about an 80-year-old man at the senior center is of most concern to the nurse? a. Decreased appetite b. Unintended weight loss c. Difficulty chewing food d. Complaints of indigestion

ANS: B Unintentional weight loss is not a normal finding and may indicate a problem such as cancer or depression. Poor appetite, difficulty in chewing, and complaints of indigestion are common in older patients. These will need to be addressed but are not of as much concern as the weight loss.

A 54-year-old man has just arrived in the recovery area after an upper endoscopy. Which information collected by the nurse is most important to communicate to the health care provider? a. The patient is very drowsy. b. The patient reports a sore throat. c. The oral temperature is 101.6° F. d. The apical pulse is 104 beats/minute.

ANS: C A temperature elevation may indicate that a perforation has occurred. The other assessment data are normal immediately after the procedure.

After assisting with a needle biopsy of the liver at a patient's bedside, the nurse should a. put pressure on the biopsy site using a sandbag. b. elevate the head of the bed to facilitate breathing. c. place the patient on the right side with the bed flat. d. check the patient's postbiopsy coagulation studies.

ANS: C After a biopsy, the patient lies on the right side with the bed flat to splint the biopsy site. Coagulation studies are checked before the biopsy. A sandbag does not exert adequate pressure to splint the site.

Which statement to the nurse from a patient with jaundice indicates a need for teaching? a. "I used cough syrup several times a day last week." b. "I take a baby aspirin every day to prevent strokes." c. "I use acetaminophen (Tylenol) every 4 hours for back pain." d. "I need to take an antacid for indigestion several times a week"

ANS: C Chronic use of high doses of acetaminophen can be hepatotoxic and may have caused the patient's jaundice. The other patient statements require further assessment by the nurse, but do not indicate a need for patient education.

Which patient choice for a snack 2 hours before bedtime indicates that the nurse's teaching about gastroesophageal reflux disease (GERD) has been effective? a. Chocolate pudding b. Glass of low-fat milk c. Cherry gelatin with fruit d. Peanut butter and jelly sandwich

ANS: C Gelatin and fruit are low fat and will not decrease lower esophageal sphincter (LES) pressure. Foods such as chocolate are avoided because they lower LES pressure. Milk products increase gastric acid secretion. High-fat foods such as peanut butter decrease both gastric emptying and LES pressure.

A patient's peripheral parenteral nutrition (PN) bag is nearly empty and a new PN bag has not arrived yet from the pharmacy. Which intervention is the priority? a. Monitor the patient's capillary blood glucose until a new PN bag is hung. b. Flush the peripheral line with saline and wait until the new PN bag is available. c. Infuse 5% dextrose in water until the new PN bag is delivered from the pharmacy. d. Decrease the rate of the current PN infusion to 10 mL/hr until the new bag arrives.

ANS: C To prevent hypoglycemia, the nurse should infuse a 5% dextrose solution until the next PN bag can be started. Decreasing the rate of the ordered PN infusion is beyond the nurse's scope of practice. Flushing the line and then waiting for the next bag may lead to hypoglycemia. Monitoring the capillary blood glucose is appropriate but is not the priority

The nurse is caring for a 54-year-old female patient on the first postoperative day after a Roux-en-Y gastric bypass procedure. Which assessment finding should be reported immediately to the surgeon? a. Bilateral crackles audible at both lung bases b. Redness, irritation, and skin breakdown in skinfolds c. Emesis of bile-colored fluid past the nasogastric (NG) tube d. Use of patient-controlled analgesia (PCA) several times an hour for pain

ANS: C Vomiting with an NG tube in place indicates that the NG tube needs to be repositioned by the surgeon to avoid putting stress on the gastric sutures. The nurse should implement actions to decrease skin irritation and have the patient cough and deep breathe, but these do not indicate a need for rapid notification of the surgeon. Frequent PCA use after bariatric surgery is expected.

The health care provider prescribes antacids and sucralfate (Carafate) for treatment of a patient's peptic ulcer. The nurse will teach the patient to take a. sucralfate at bedtime and antacids before each meal. b. sucralfate and antacids together 30 minutes before meals. c. antacids 30 minutes before each dose of sucralfate is taken. d. antacids after meals and sucralfate 30 minutes before meals.

ANS: D Sucralfate is most effective when the pH is low and should not be given with or soon after antacids. Antacids are most effective when taken after eating. Administration of sucralfate 30 minutes before eating and antacids just after eating will ensure that both drugs can be most effective. The other regimens will decrease the effectiveness of the medications.

Which assessment should the nurse perform first for a patient who just vomited bright red blood? a. Measuring the quantity of emesis b. Palpating the abdomen for distention c. Auscultating the chest for breath sounds d. Taking the blood pressure (BP) and pulse

ANS: D The nurse is concerned about blood loss and possible hypovolemic shock in a patient with acute gastrointestinal (GI) bleeding. BP and pulse are the best indicators of these complications. The other information is important to obtain, but BP and pulse rate are the best indicators for assessing intravascular volume.

When caring for a patient with a history of a total gastrectomy, the nurse will monitor for a. constipation. b. dehydration. c. elevated total serum cholesterol. d. cobalamin (vitamin B12) deficiency.

ANS: D The patient with a total gastrectomy does not secrete intrinsic factor, which is needed for cobalamin (vitamin B12) absorption. Because the stomach absorbs only small amounts of water and nutrients, the patient is not at higher risk for dehydration, elevated cholesterol, or constipation.

The nurse explaining esomeprazole (Nexium) to a patient with recurring heartburn describes that the medication a. reduces gastroesophageal reflux by increasing the rate of gastric emptying. b. neutralizes stomach acid and provides relief of symptoms in a few minutes. c. coats and protects the lining of the stomach and esophagus from gastric acid. d. treats gastroesophageal reflux disease by decreasing stomach acid production.

ANS: D The proton pump inhibitors decrease the rate of gastric acid secretion. Promotility drugs such as metoclopramide (Reglan) increase the rate of gastric emptying. Cryoprotective medications such as sucralfate (Carafate) protect the stomach. Antacids neutralize stomach acid and work rapidly.

A 50-year-old man vomiting blood-streaked fluid is admitted to the hospital with acute gastritis. To determine possible risk factors for gastritis, the nurse will ask the patient about a. the amount of saturated fat in the diet. b. any family history of gastric or colon cancer. c. a history of a large recent weight gain or loss. d. use of nonsteroidal antiinflammatory drugs (NSAIDs).

ANS: D Use of an NSAID is associated with damage to the gastric mucosa, which can result in acute gastritis. Family history, recent weight gain or loss, and fatty foods are not risk factors for acute gastritis
