Etiology and Risk Factors

- The main causes of peptic ulcers are infection with H. pylori bacteria and long-term use of NSAIDs.

i.H. pylori is a spiral-shaped bacterium that colonizes the stomach and duodenum. It can damage the mucosa by producing enzymes, toxins, and inflammatory substances. It can also interfere with the production of protective mucus and bicarbonate in the stomach. H. pylori infection is very common, affecting about half of the world's population. It is more prevalent in developing countries, where it is usually acquired in childhood. It can be transmitted from person to person through oral-oral or fecal-oral routes, or through contaminated food or water.

ii.NSAIDs are a group of drugs that are used to relieve pain, inflammation, and fever. They include aspirin, ibuprofen, naproxen, celecoxib, and others. NSAIDs can cause peptic ulcers by inhibiting an enzyme called cyclooxygenase (COX), which is involved in the synthesis of prostaglandins. Prostaglandins are substances that protect the mucosa from acid and injury. NSAIDs are widely used for various conditions such as arthritis, headache, menstrual cramps, and sports injuries. They can increase the risk of peptic ulcers by 2 to 4 times, especially if taken at high doses, for long periods, or in combination with other drugs such as steroids or anticoagulants.

  • Other risk factors for peptic ulcers include:
    • Smoking: Smoking can increase acid secretion, reduce blood flow to the mucosa, impair healing of ulcers, and reduce the effectiveness of medications.
    • Alcohol: Alcohol can irritate the mucosa, increase acid production, and interfere with the action of prostaglandins.
    • Stress: Stress can stimulate acid secretion and impair mucosal defense mechanisms. However, stress alone does not cause peptic ulcers unless there is also H. pylori infection or NSAID use.
    • Spicy foods: Spicy foods do not cause peptic ulcers, but they may worsen symptoms in some people who have existing ulcers.
    • Genetic factors: Some people may have a genetic predisposition to peptic ulcers due to variations in genes that affect acid secretion, mucosal protection, or immune response to H. pylori.

Questions on Etiology and Risk Factors

Correct Answer is C

Explanation

While stress and emotional factors may exacerbate peptic ulcer symptoms, they are not the primary cause of the condition. The primary causes are H. pylori infection and the use of NSAIDs.

Correct Answer is A

Explanation

The frequency of consuming high-fiber foods is not specifically related to peptic ulcer disease. However, diet history is essential for overall health assessment.

Correct Answer is B

Explanation

Taking the PPI before bedtime may not provide the best acid suppression throughout the day. Taking it on an empty stomach before a meal is a more appropriate approach.

Correct Answer is D

Explanation

This statement is correct. An endoscopy involves inserting a flexible tube (endoscope) with a camera on the end through the mouth to examine the stomach and duodenum. It is a commonly used procedure to assess and diagnose peptic ulcer disease.

Correct Answer is B

Explanation

Citrus fruits and juices are acidic and can aggravate the stomach lining in a client with peptic ulcer disease. It is best to avoid or limit their consumption. QUESTIONS

Correct Answer is A

Explanation

While stress and emotional factors may exacerbate peptic ulcer symptoms, they are not the primary cause of the condition. The primary causes are Helicobacter pylori infection and the use of nonsteroidal anti-inflammatory drugs (NSAIDs).

Correct Answer is D

Explanation

This statement is correct. Long-term use of NSAIDs is a well-established risk factor for peptic ulcer disease. NSAIDs can irritate the stomach lining and increase the risk of ulcer formation.

Correct Answer is C

Explanation

Helicobacter pylori infection is not caused by excessive consumption of spicy foods. The infection is typically acquired through person-to-person transmission, such as through contaminated water or food, and is unrelated to diet choices.

Correct Answer is C

Explanation

While a high-fiber diet is generally beneficial for digestive health, it does not specifically counteract the effects of NSAIDs on the stomach lining.

Correct Answer is A

Explanation

Regular physical exercise is important for overall health, but it is not a direct risk factor for peptic ulcer disease. The nurse should focus on risk factors related to diet, medication use, and other medical conditions. QUESTIONS

Correct Answer is A

Explanation

Diffuse abdominal pain with a low-grade fever may be seen in various conditions, but it does not specifically point to cholecystitis.

Correct Answer is C

Explanation

Elevated serum amylase is more associated with pancreatitis rather than cholecystitis. It is not directly related to the clinical manifestations described.

Correct Answer is D

Explanation

This statement is correct. High fever and chills may indicate the presence of infection and sepsis, which can be severe complications of acute cholecystitis.

Correct Answer is A

Explanation

Decreased production of pancreatic enzymes may lead to malabsorption issues and cause symptoms like diarrhea and steatorrhea. However, it is not the primary cause of indigestion and bloating after meals in chronic cholecystitis.

Correct Answer is C

Explanation

Auscultation of the left upper quadrant is not relevant to assessing for Boas' sign, which involves the right upper quadrant.

Correct Answer is C

Explanation

ERCP is an invasive procedure used to visualize the biliary and pancreatic ducts, but it is not typically used as a first-line diagnostic test for cholecystitis.

Correct Answer is C

Explanation

Avoiding pain medications is not necessary before an abdominal ultrasound. The client can continue taking prescribed medications as usual.

Correct Answer is C

Explanation

Low serum bilirubin levels are not consistent with cholecystitis, which can cause obstructive jaundice and elevated bilirubin levels due to bile duct obstruction.

Correct Answer is B

Explanation

Providing detailed images of the pancreas is not the primary purpose of a HIDA scan, although it can sometimes provide some information about the pancreas if the tracer reaches the duodenum and enters the common bile duct.

Correct Answer is B

Explanation

CT scans use X-rays, not sound waves. Sound waves are used in ultrasound imaging, not in CT scans.

This statement is incorrect and indicates a need for further teaching. Alcohol can irritate the stomach lining and exacerbate peptic ulcer disease. Clients with peptic ulcers should avoid or minimize alcohol consumption.

Administering antacids at bedtime may help with overnight acid reduction, but it may not adequately address pain during meals when acid production is higher.

Antibiotics do not relax stomach muscles or alleviate abdominal pain. Pain relief is typically achieved through acid-reducing medications and other pain management strategies.

Recovering fully in 6 months may be an extended recovery period. While some clients may experience a longer recovery, it is not a standard time frame for everyone.

High-fiber foods can be beneficial for overall digestive health, but they are not specifically recommended for promoting ulcer healing. In some cases, high-fiber foods may need to be avoided if they cause discomfort.

Feeling fatigued and sleepy after meals is not typically associated with peptic ulcer disease or its complications.

This statement is correct. A perforated peptic ulcer can cause increased abdominal rigidity due to the inflammation and irritation of the peritoneal lining. The abdomen may feel tense and rigid upon palpation.

Avoiding alcohol is advisable while on NSAIDs as alcohol can increase the risk of gastrointestinal bleeding and worsen peptic ulcer disease.

Checking for drug interactions with other medications is essential for safe medication administration, but it is not the priority when administering PPIs intravenously to this client.

Diagnosing conditions in the lower digestive tract is not the purpose of an upper gastrointestinal endoscopy. Lower digestive tract evaluations are typically done using colonoscopy or sigmoidoscopy.

It is essential to avoid taking sucralfate with other medications, especially those that require an acidic environment for absorption. This is because sucralfate can decrease the absorption of certain drugs.

Providing the client with spicy foods is not advisable, as they can irritate the stomach lining and worsen symptoms for the client with peptic ulcer disease.

H2 receptor blockers are not known to affect the CBC, so monitoring the complete blood count is not the priority for this client.

Hyperactive bowel sounds are not early signs of gastrointestinal bleeding. Bowel sounds may be hyperactive or hypoactive depending on the severity of the bleeding and associated factors.

Misoprostol is not used to reduce stomach acid production. Instead, it helps protect the stomach lining by increasing mucus production and promoting bicarbonate secretion.

Regular use of NSAIDs can increase the risk of developing peptic ulcers and is not a preventive strategy for clients with a history of peptic ulcer disease.

This statement is correct. Antacids can interfere with the action of PPIs, and clients should avoid taking them together. If needed, antacids should be taken at least 1 hour before or after the PPI.

Caffeine-containing beverages should be limited or avoided, as caffeine can stimulate gastric acid secretion and may worsen symptoms for clients with peptic ulcers.

Taking over-the-counter antacids regularly is not a preventive strategy for H. pylori reinfection. Antacids do not target the bacterium and are not effective in eradicating H. pylori.

Sucralfate does not typically cause drowsiness, so taking it before bedtime is not necessary for this medication. It should be taken at regular intervals during the day as prescribed.
