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.

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

pain 2 to 3 hours after a meal.

The nurse practitioner prescribes a histamine-2 receptor for a critically ill patient with a peptic ulcer. Select the drug that is considered the best choice for this category of patient.

pepcid -Pepcid causes the fewest drug-to-drug interactions and does not alter liver metabolism.

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." -Tetracycline may cause a photosensitivity reaction in clients. The nurse should caution the client to use sunscreen when taking this drug. Dairy products can reduce the effectiveness of tetracycline, so the nurse should not advise him or her to take the medication with milk.

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.

A 66-year-old African-American client has recently visited a physician to confirm a diagnosis of gastric cancer. The client has a history of tobacco use and was diagnosed 10 years ago with pernicious anemia. He and his family are shocked about the possibility of cancer because he was asymptomatic prior to recent complaints of pain and multiple gastrointestinal symptoms. On the basis of knowledge of disease progression, the nurse assumes that organs adjacent to the stomach are also affected. Which of the following organs may be affected?

Liver Pancreas Duodenum Most gastric cancers are adenocarcinomas; they can occur anywhere in the stomach. The tumor infiltrates the surrounding mucosa, penetrating the wall of the stomach and adjacent organs and structures. The liver, pancreas, esophagus, and duodenum are often already affected at the time of diagnosis. Metastasis through lymph to the peritoneal cavity occurs later in the disease.

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

Ingestion of strong acids Irritating foods 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 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.

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 - 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.
