CH 47 - GASTRIC/DUODENAL DISORDERS

A nursing student is caring for a client with gastritis. Which of the following would the student recognize as a common cause of gastritis? Choose all that apply.

Irritating foods Ingestion of strong acids Overuse of aspirin Acute gastritis is often caused by dietary indiscretion—a person eats food that is irritating, too highly seasoned, or contaminated with disease-causing microorganisms. Other causes of acute gastritis include overuse of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), excessive alcohol intake, bile reflux, and radiation therapy. A more severe form of acute gastritis is caused by the ingestion of strong acid or alkali, which may cause the mucosa to become gangrenous or to perforate. A DASH diet is an accronym for Dietary Approaches to Stop Hypertension, which would not cause gastritis. Participation in competitive sports also would not cause gastritis.

A patient has been diagnosed with acute gastritis and asks the nurse what could have caused it. What is the best response by the nurse? (Select all that apply.)

"It can be caused by ingestion of strong acids." "You may have ingested some irritating foods." "Is it possible that you are overusing aspirin."

A patient being treated for pyloric obstruction has a nasogastric (NG) tube in place to decompress the stomach. The nurse routinely checks for a residual amount that would indicate obstruction. Choose that amount.

450 mL A residual of greater than 400 mL strongly suggests obstruction.

A client is recovering from gastric surgery. Toward what goal should the nurse progress the client's enteral intake?

Six small meals daily with 120 mL fluid between meals

A client is recovering from gastric surgery. Toward what goal should the nurse progress the client's enteral intake?

Six small meals daily with 120 mL fluid between meals After the return of bowel sounds and removal of the nasogastric tube, the nurse may give fluids, followed by food in small portions. Foods are gradually added until the client can eat six small meals a day and drink 120 mL of fluid between meals.

The nurse recognizes that the patient diagnosed with a duodenal ulcer will likely experience

pain 2 to 3 hours after a meal. The patient with a gastric ulcer often awakens between 1 to 2 with pain, and ingestion of food brings relief

The nurse is conducting preoperative teaching to a patient prior to bariatric surgery. The nurse includes that the average weight loss of patients after bariatric surgery is which percent of their presurgical body weight?

25 to 35% The nurse includes that the average weight loss of a patients after bariatric surgery is 25 to 35% of their presurgical body weight.

A client is prescribed tetracycline to treat peptic ulcer disease. Which of the following instructions would the nurse give the client?

"Be sure to wear sunscreen while taking this medicine."

The nurse determines that teaching for the client with peptic ulcer disease has been effective when the client states:

"I have learned some relaxation strategies that decrease my stress." The nurse assists the client to identify stressful or exhausting situations. A hectic lifestyle and an irregular schedule may aggravate symptoms and interfere with regular meals taken in relaxed settings along with the regular administration of medications. The client may benefit from regular rest periods during the day, at least during the acute phase of the disease. Biofeedback, hypnosis, behavior modification, massage, or acupuncture may be helpful.

A nurse is performing discharge teaching with a client who had a total gastrectomy. Which statement indicates the need for further teaching?

"I will have to take vitamin B12 shots up to 1 year after surgery."

A client weighs 215 lbs and is 5' 8" tall. The nurse would calculate this client's body mass index (BMI) as which of the following?

32.7 Using the formula for BMI, the client's weight in pounds (215) is divided by the height in inches squared (68 inches squared) and then multiplied by 703. The result would be 32.7.

The nurse is caring for a patient who has been diagnosed with gastritis. To promote fluid balance when treating gastritis, the nurse knows that what minimal daily intake of fluids is required?

1.5 L Daily fluid intake and output are monitored to detect early signs of dehydration (minimal fluid intake of 1.5 L/day, minimal output of 0.5 mL/kg/h).

A client with peptic ulcer disease must begin triple medication therapy. For how long will the client follow this regimen?

10 to 14 days Recommended therapy for 10 to 14 days includes triple therapy with two antibiotics (eg, metronidazole [Flagyl] or amoxicillin [Amoxil] and clarithromycin [Biaxin]) plus a proton pump inhibitor (eg, lansoprazole [Prevacid], omeprazole [Prilosec], or rabeprazole [Aciphex]), or quadruple therapy with two antibiotics (metronidazole and tetracycline) plus a proton pump inhibitor and bismuth salts (Pepto-Bismol)

Morbid obesity is defined as being how many pounds over the person's ideal body weight?

100

A client reports to the clinic, stating that she rapidly developed headache, abdominal pain, nausea, hiccuping, and fatigue about 2 hours ago. For dinner, she ate buffalo chicken wings and beer. Which of the following medical conditions is most consistent with the client's presenting problems?

Acute gastritis The client with acute gastritis may have a rapid onset of symptoms, including abdominal discomfort, headache, lassitude, nausea, anorexia, vomiting, and hiccuping, which can last from a few hours to a few days. Acute gastritis is often caused by dietary indiscretion--a person eats food that is irritating, too highly seasoned, or contaminated with disease-causing microorganisms.

The nurse is conducting an admission assessment and determines that the patient's BMI is 37. The nurse documents the BMI as being which of the following classes of obesity?

Class II

A patient has a BMI ranger greater than 40 kg/m2. What would this patient's obesity classification be?

Class III

Which of the following clients is at highest risk for peptic ulcer disease?

Client with blood type O Clients with blood type O are more susceptible to peptic ulcers than those with blood types A, B, and AB.

A client experienced extensive burns and 72 hours later has developed an ulcer. Which of the following types of ulcer is most likely in this client?

Curling's ulcer

Which of the following appears to be a significant factor in the development of gastric cancer?

Diet Diet seems to be a significant factor: a diet high in smoked, salted, or pickled foods and low in fruits and vegetables may increase the risk of gastric cancer. The typical patient with gastric cancer is between 50 and 70 years of age. Men have a higher incidence than women. Native Americans, Hispanic Americans, and African Americans are twice as likely as Caucasian Americans to develop gastric cancer.

Which of the following is the first portion of the small intestine?

Duodenum The duodenum is the first portion of the small intestine, between the stomach and the jejunum. The pylorus is the opening between the stomach and duodenum. The peritoneum is the thin membrane that lines the inside of the wall of the abdomen and covers all the abdominal organs. The omentum is the fold of the peritoneum that surrounds the stomach and other organs of the abdomen

A physician suspects that a client has peptic ulcer disease. With which of the following diagnostic procedures would the nurse most likely prepare to assist?

Endoscopy Endoscopy is the preferred diagnostic procedure because it allows direct visualization of inflammatory changes, ulcers, and lesions. Through endoscopy, a biopsy of the gastric mucosa and of any suspicious lesions can be obtained. Endoscopy may reveal lesions that, because of their size or location, are not evident on x-ray studies. Less invasive diagnostic measures for detecting H. pylori include serologic testing for antibodies against the H. pylori antigen, stool antigen test, and urea breath test.

The nurse is caring for a client who has just returned from the PACU after surgery for peptic ulcer disease. For what potential complications does the nurse know to monitor? Select all that apply

Hemorrhage Perforation Penetration Pyloric obstruction Potential complications may include hemorrhage, perforation, penetration, and pyloric obstruction. A client who has had surgery for peptic ulcer disease may have a decreased appetite in the immediate postoperative stage, but it is not something the nurse would monitor for and would not cause cachexia. Inability to clear secretions is generally not a complication of peptic ulcer surgery.

Which of the following is a true statement regarding the nursing considerations in administration of metronidazole (Flagyl)?

It leaves a metallic taste in the mouth. Flagyl leaves a metallic taste in the mouth. It may cause anorexia and should be given with meals to decrease GI upset. Flagyl increases the blood-thinning effects of warfarin (Coumadin).

Rebleeding may occur from a peptic ulcer and often warrants surgical interventions. Signs of bleeding include which of the following?

Mental confusion Signs of bleeding include tachycardia, tachypnea, hypotension, mental confusion, thirst, and oliguria.

A nurse is caring for a client with active upper GI bleeding. What is the appropriate diet for this client during the first 24 hours after admission?

Nothing by mouth Shock and bleeding must be controlled before oral intake, so the client should receive nothing by mouth. When the bleeding is controlled, the diet is gradually increased, starting with ice chips and then clear liquids. Skim milk shouldn't be given because it increases gastric acid production, which could prolong bleeding. A clear liquid diet is the first diet offered after bleeding and shock are controlled.

Peptic ulcer disease occurs more frequently in people with which blood type?

O

Which of the following represents the medication classification of a proton (gastric acid) pump inhibitor?

Omeprazole (Prilosec) Omeprazole decreases gastric acid by slowing the hydrogen-potassium adenosine triphosphatase pump on the surface of the parietal cells. Sucralfate is a cytoprotective drug. Famotidine is a histamine-2 receptor antagonist. Metronidazole is an antibiotic, specifically an amebicide.

Which of the following are classified as a histamine-2 receptor antagonist?

Pepcid

A patient is in the hospital for the treatment of peptic ulcer disease. The nurse finds the patient vomiting and complaining of a sudden severe pain in the abdomen. The nurse then assesses a board-like abdomen. What does the nurse suspect these symptoms indicate?

Perforation of the peptic ulcer Signs and symptoms of perforation include the following: Sudden, severe upper abdominal pain (persisting and increasing in intensity), which may be referred to the shoulders, especially the right shoulder, because of irritation of the phrenic nerve in the diaphragm; vomiting; collapse (fainting); extremely tender and rigid (boardlike) abdomen; and hypotension and tachycardia, indicating shock.

The nurse advises the patient who has just been diagnosed with acute gastritis to:

Refrain from food until the GI symptoms subside.

Which of the following is the most successful treatment for gastric cancer?

Removal of the tumor

A patient is scheduled for a Billroth I procedure for ulcer management. What does the nurse understand will occur when this procedure is performed?

A partial gastrectomy is performed with anastomosis of the stomach segment to the duodenum. A Billroth I procedure involves removal of the lower portion of the antrum of the stomach (which contains the cells that secrete gastrin) as well as a small portion of the duodenum and pylorus. The remaining segment is anastomosed to the duodenum.

A client with gastric cancer is having a resection. What is the nursing management priority for this client?

Correcting nutritional deficits Clients with gastric cancer commonly have nutritional deficits and may have cachexia. Therefore, correcting nutritional deficits is a top priority. Discharge planning before surgery is important, but correcting the nutritional deficits is a higher priority. Radiation therapy hasn't been proven effective for gastric cancer, and teaching about it preoperatively wouldn't be appropriate. Preventing DVT isn't a high priority before surgery, but it assumes greater importance after surgery.

A nurse caring for a patient in a burn treatment center knows to assess for the presence of which of the following types of ulcer about 72 hours post injury?

Curling's Curling's ulcer results from a complication from severe burns that causes reduced plasma volume that affects the gastric mucosa. Cushing's ulcer is produced by elevated intracranial pressure and is common with head injuries and brain trauma.

Symptoms associated with pyloric obstruction include all of the following except:

Diarrhea Pyloric obstruction, also called gastric outlet obstruction (GOO), occurs when the area distal to the pyloric sphincter becomes scarred and stenosed from spasm or edema or from scar tissue that forms when an ulcer alternately heals and breaks down. The client may have nausea and vomiting, constipation, epigastric fullness, anorexia, and, later, weight loss.

Clients with Type O blood are at higher risk for which of the following GI disorders?

Duodenal ulcers Familial tendency also may be a significant predisposing factor. People with blood type O are more susceptible to peptic ulcers than are those with blood type A, B, or AB. Blood type is not a predisposing factor for gastric cancer, esophageal varices, and diverticulitis.

A patient who had bariatric surgery complains of diarrhea. The nurse recommends which of the following dietary changes?

Increased fiber The nurse recommends that the patient increase fiber in the diet because a high-fiber diet can decrease both diarrhea and constipation after bariatric surgery.

The nurse is developing a plan of care for a patient with peptic ulcer disease. What nursing interventions should be included in the care plan? (Select all that apply.)

Frequently monitoring hemoglobin and hematocrit levels Observing stools and vomitus for color, consistency, and volume Checking the blood pressure and pulse rate every 15 to 20 minutes The nurse assesses the patient for faintness or dizziness and nausea, which may precede or accompany bleeding. The nurse must monitor vital signs frequently and evaluate the patient for tachycardia, hypotension, and tachypnea. Other nursing interventions include monitoring the hemoglobin and hematocrit, testing the stool for gross or occult blood, and recording hourly urinary output to detect anuria or oliguria (absence of or decreased urine production).

Which of the following is the most common complication associated with peptic ulcer?

Hemorrhage Hemorrhage, the most common complication, occurs in 28% to 59% of patients with peptic ulcers. Vomiting, elevated temperature, and abdominal pain are not the most common complications of a peptic ulcer.

Which of the following is a true statement regarding gastric cancer?

Most patients are asymptomatic during the early stage of the disease. Most patients are asymptomatic during the early stage of the disease. Men have a higher incidence of gastric cancer. The prognosis is poor because the diagnosis is usually made late because most patients are asymptomatic during the early stage. Most cases of gastric cancer are discovered only after local invasion has advanced or metastases are present.

The nurse is conducting a community health education program on obesity. The nurse includes which of the following diseases/disorders in the program?

Obstructive sleep apnea The nurse includes that obstructive sleep apnea is a disease/disorder associated with obesity as well as asthma; breast, endometrial, prostate, renal, colon, and gallbladder cancer; osteoarthritis, coronary artery disease, cholecystitis, cholelithiasis, chronic back pain, diabetes, hypertension, coronary artery disease, heart failure, and pulmonary embolism.

The nurse is conducting a community education class on gastritis. The nurse includes that chronic gastritis caused by Helicobacter pylori is implicated in which of the following diseases/conditions?

Peptic ulcers Chronic gastritis caused by Helicobacter pylori is implicated in the development of peptic ulcers. Chronic gastritis is sometimes associated with autoimmune disease, such as pernicious anemia, but not as a cause of the anemia. Chronic gastritis is not implicated in system infections and/or colostomies.

A patient has a Class II classification of obesity. What level of health risk does this pose for the patient?

Severe risk Class II obesity is associated with severe risk. Overweight is associated with mild risk, Class I obesity with moderate risk, and Class III obesity with very severe risk.

Which of the following is included as a dietary guideline for a patient who has had bariatric surgery?

Restrict total meal size to less than 1 cup. Dietary guidelines would include a restriction of total meal size to less than 1 cup. The patient should eat three meals per day. Avoid liquid calories such as soda. The patient should drink plenty of water, from 90 minutes after each meal to 15 minutes before the next meal.

Why are antacids administered regularly, rather than as needed, in peptic ulcer disease?

To keep gastric pH at 3.0 to 3.5 To maintain a gastric pH of 3.0 to 3.5 throughout each 24-hour period, regular (not as needed) doses of an antacid are needed to treat peptic ulcer disease. Frequent administration of an antacid tends to decrease client compliance rather than promote it. Antacids don't regulate bowel patterns, and they decrease pepsin activity.

After a client received a diagnosis of gastric cancer, the surgical team decides that a Billroth II would be the best approach to treatment. The nurse explains to the family that this procedure involves:

Wide resection of the middle and distal prtions of the stomach with removal of about 75% of the stomach. The Billroth I involves a limited resection and offers a lower cure rate than the Billroth II. The Billroth II procedure is a wider resection that involves removing approximately 75% of the stomach and decreases the possibility of lymph node spread or metastatic recurrence. A proximal subtotal gastrectomy may be performed for a resectable tumor located in the proximal portion of the stomach or cardia. A total gastrectomy or an esophagogastrectomy is usually performed in place of this procedure to achieve a more extensive resection.

A nurse is teaching a group of middle-aged men about peptic ulcers. When discussing risk factors for peptic ulcers, the nurse should mention:

alcohol abuse and smoking. The nurse should mention that risk factors for peptic (gastric and duodenal) ulcers include alcohol abuse, smoking, and stress.

A client is admitted to the health care facility with a diagnosis of a bleeding gastric ulcer. The nurse expects this client's stools to be:

black and tarry. Black, tarry stools are a sign of bleeding high in the GI tract, as from a gastric ulcer, and result from the action of digestive enzymes on the blood. Vomitus associated with upper GI tract bleeding commonly is described as coffee-ground-like. Clay-colored stools are associated with biliary obstruction. Bright red stools indicate lower GI tract bleeding.

A nurse is providing follow-up teaching at a clinic visit for a client recovering from gastric resection. The client reports sweating, diarrhea, nausea, palpitations, and the desire to lie down 15 to 30 minutes after meals. The nurse suspects the client has

dumping syndrome. Early manifestations of dumping syndrome occur 15 to 30 minutes after eating. Signs and symptoms include vertigo, tachycardia, syncope, sweating, pallor, palpitations, diarrhea, nausea, and the desire to lie down. Dehiscence of the surgical wound is characterized by pain and a pulling or popping feeling at the surgical site. Peritonitis presents with a rigid, boardlike abdomen, tenderness, and fever. The client's signs and symptoms aren't a normal reaction to surgery.

A nurse is caring for a client who underwent a subtotal gastrectomy 24 hours ago. The client has a nasogastric (NG) tube. The nurse should:

irrigate the NG tube gently with normal saline solution if ordered The nurse can gently irrigate the tube if ordered, but must be careful not to reposition it. Repositioning can cause bleeding. The nurse should apply suction continuously — not every hour. The nurse shouldn't clamp the NG tube postoperatively because secretions and gas will accumulate, stressing the suture line.

A nurse is caring for a client who is undergoing a diagnostic workup for a suspected GI problem. The client reports gnawing epigastric pain following meals and heartburn. The nurse suspects the client has:

peptic ulcer disease. Peptic ulcer disease is characterized by dull, gnawing pain in the midepigastrium or the back that worsens with eating. Ulcerative colitis is characterized by exacerbations and remissions of severe bloody diarrhea. Appendicitis is characterized by epigastric or umbilical pain along with nausea, vomiting, and low-grade fever. Pain caused by diverticulitis is in the left lower quadrant and has a moderate onset. It's accompanied by nausea, vomiting, fever, and chills

A client is admitted to the hospital with an exacerbation of his chronic gastritis. When assessing his nutritional status, the nurse should expect a deficiency in:

vitamin B12 The nurse should expect vitamin B12 deficiency. Injury to the gastric mucosa causes gastric atrophy and impaired function of the parietal cells. These changes result in reduced production of intrinsic factor, which is necessary for the absorption of vitamin B12. Eventually, pernicious anemia will occur. Deficiencies in vitamins A, B6, and C aren't expected in a client with chronic gastritis.

A nurse is caring for a client who underwent a subtotal gastrectomy. To manage dumping syndrome, the nurse should advise the client to:

drink liquids only between meals. A client who experiences dumping syndrome after a subtotal gastrectomy should be advised to ingest liquids between meals rather than with meals. Taking fluids between meals allows for adequate hydration, reduces the amount of bulk ingested with meals, and aids in the prevention of rapid gastric emptying. There is no need to restrict the amount of fluids, just the time when the client drinks fluids. Drinking liquids with meals increases the risk of dumping syndrome by increasing the amount of bulk and stimulating rapid gastric emptying. Small amounts of water are allowable before meals.

A client admitted for treatment of a gastric ulcer is being prepared for discharge on antacid therapy. Discharge teaching should include which instruction?

"Continue to take antacids even if your symptoms subside." Antacids decrease gastric acidity and should be continued even if the client's symptoms subside. Because other medications may interfere with antacid action, the client should avoid taking antacids concomitantly with other drugs. If cardiac problems arise, the client should avoid antacids containing sodium, not magnesium. For optimal results, the client should take an antacid 1 hour before or 2 hours after meals

Which of the following ulcers is associated with extensive burn injury?

Curling's ulcer Curling's ulcer is frequently observed about 72 hours after extensive burns and involves the antrum of the stomach or the duodenum.

When caring for a client with an acute exacerbation of a peptic ulcer, the nurse finds the client doubled up in bed with severe pain to his right shoulder. The intial appropriate action by the nurse is to

Assess the client's abdomen and vital signs. Signs and symptoms of perforation includes sudden, severe upper abdominal pain (persisting and increasing in intensity); pain may be referred to the shoulders, especially the right shoulder, because of irritation of the phrenic nerve in the diaphragm. The nurse should assess the vital signs and abdomen prior to notifying the physician. Irrigation of the NG tube should not be performed because the additional fluid may be spilled into the peritoneal cavity, and the client should be placed in a position of comfort, usually on the side with the head slightly elevated.

The nurse is caring for a patient after bariatric surgery who experiences symptoms of gastric outlet obstruction. Which of the following are contraindicated?

NG tube

Which of the following surgical procedures for obesity utilizes a prosthetic device to restrict oral intake?

Gastric banding In gastric banding, a prosthetic device is used to restrict oral intake by creating a small pouch of 10 to 15 milliliters that empties through the narrow outlet into the remainder of the stomach. Roux-en-Y gastric bypass uses a horizontal row of staples across the fundus of the stomach to create a pouch with a capacity of 20 to 30 mL. Vertical-banded gastroplasty involves placement of a vertical row of staples along the lesser curvature of the stomach, creating a new, small gastric pouch. Biliopancreatic diversion with duodenal switch combines gastric restriction with intestinal malabsorption.

A client with a peptic ulcer is diagnosed with Heliobacter pylori infection. The nurse is teaching the client about the medications prescribed, including metronidazole (Flagyl), omeprazole (Prilosec), and clarithromycin (Biaxin). Which statement by the client indicates the best understanding of the medication regimen?

"The medications will kill the bacteria and stop the acid production." Currently, the most commonly used therapy for peptic ulcers is a combination of antibiotics, proton-pump inhibitors, and bismuth salts that suppress or eradicate H. pylori. Recommended therapy for 10 to 14 days includes triple therapy with two antibiotics (eg, metronidazole [Flagyl] or amoxicillin [Amoxil] and clarithromycin [Biaxin]) plus a proton-pump inhibitor (eg, lansoprazole [Prevacid], omeprazole [Prilosec], or rabeprazole [Aciphex]), or quadruple therapy with two antibiotics (metronidazole and tetracycline) plus a proton-pump inhibitor and bismuth salts (Pepto-Bismol). Research is being conducted to develop a vaccine against H. pylori.

The nurse is cautiously assessing a client admitted with peptic ulcer disease because the most common complication that occurs in 10% to 20% of clients is:

Hemorrhage

After teaching a client who has had a Roux-en-Y gastric bypass, which client statement indicates the need for additional teaching?

"I need to drink 8 ounces of water before eating." After a Roux-en-Y gastric bypass, the client should not drink fluids with meals, withholding fluids for 15 minutes before eating to 90 minutes after eating. Chewing foods slowly and thoroughly, keeping total serving sizes to less than 1 cup, and choosing foods such as breads, cereals, and grains that provide less than 2 g of fiber per serving.

A client with severe peptic ulcer disease has undergone surgery and is several hours postoperative. During assessment, the nurse notes that the client has developed cool skin, tachycardia, and labored breathing; the client also appears to be confused. Which of the following complications has the client most likely developed?

Hemorrhage Signs of hemorrhage following surgery include cool skin, confusion, increased heart rate, labored breathing, and blood in the stool. Signs of penetration and perforation are severe abdominal pain, rigid and tender abdomen, vomiting, elevated temperature, and increased heart rate. Indicators of pyloric obstruction are nausea, vomiting, distended abdomen, and abdominal pain.

The nurse is reviewing the medication record of a client with acute gastritis. Which medication, if noted on the client's record, would the nurse question?

Indomethacin (Indocin) Indomethacin is a nonsterioidal anti-inflammatory drug and can cause ulceration of the esophagus, stomach, or small intestine. Indomethacin is contraindicated in a client with a gastrointestinal disorder. The other medications are not contraindicated in clients with gastrointestinal disorders.

A nurse practitioner prescribes drug therapy for a patient with peptic ulcer disease. Choose the drug that can be used for 4 weeks and has a 90% chance of healing the ulcer.

Omeprazole (Prilosec)

The client has been taking famotidine (Pepcid) at home. The nurse prepares a teaching plan for the client indicating that the medication acts primarily to achieve which of the following?

Inhibit gastric acid secretions. Famotidine is useful for treating and preventing ulcers and managing gastroesophageal reflux disease. It functions by inhibiting the action of histamine at the H-2 receptor site located in the gastric parietal cells, thus inhibiting gastric acid secretion.

Which of the following medications used for the treatment of obesity prevents the absorption of triglycerides?

Orlistat (Xenical) Orlistat (Xenical) prevents the absorption of triglycerides. Side effects of Xenical may include increased bowel movements, gas with oily discharge, decreased food absorption, decreased bile flow, and decreased absorption of some vitamins. Bupropion hydrochloride (Wellbutrin) is an antidepressant medication. Sibutramine hydrochloride (Meridia) inhibits the reuptake of serotonin and norepinephrine. Meridia decreases appetite. Fluoxetine hydrochloride (Prozac) has not been approved by the FDA for use in the treatment of obesity.

A nurse is providing care for a client recovering from gastric bypass surgery. During assessment, the client exhibits pallor, perspiration, palpitations, headache, and feelings of warmth, dizziness, and drowsiness. The client reports eating 90 minutes ago. The nurse suspects:

Vasomotor symptoms associated with dumping syndrome Early manifestations of dumping syndrome occur 15 to 30 minutes after eating. Signs and symptoms include vertigo, tachycardia, syncope, sweating, pallor, palpitations, diarrhea, nausea, and the desire to lie down. Dehiscence of the surgical wound is characterized by pain and a pulling or popping feeling at the surgical site. Peritonitis presents with a rigid, boardlike abdomen, tenderness, and fever. The client's signs and symptoms aren't a normal reaction to surgery.

The nurse is caring for a client with chronic gastritis. The nurse monitors the client knowing that this client is at risk for which vitamin deficiency?

Vitamin B12 Clients with chronic gastritis from vitamin deficiency usually have evidence of malabsorption of vitamin B12 caused by the production of antibodies that interfere with the binding of vitamin B12 to intrinsic factor. However, some clients with chronic gastritis have no symptoms. Vitamins A, C, and E are not affected by gastritis.
