What is the medical treatment for ACUTE GASTRITIS?

Acute gastritis is treated symptomatically & supportively because the healing process is spontaneous, usually occurring within a few days. When the cause is removed, pain & discomfort usually subside. If bleeding is severe, a blood transfusion may be necessary. Fluid replacement is prescribed for patients with severe fluid loss. Surgery, such as partial gastrectomy, pyloroplasty, and/or vagotomy, may be needed for patients with major bleeding or ulceration.

What causes Atrophic Gastritis?

Atrophic Gastritis occurs as a result of bacterial overgrowth.

Describe ATROPHIC GASTRITIS

Atrophic gastritis is a type of chronic gastritis that is seen most often in older adults. It can occur after exposure to toxic substances in the workplace (e.g., benzene, lead, nickel) or H. pylori infection, or it can be related to autoimmune factors. Atrophic gastritis can lead to two types of cancer: gastric cancer and gastric mucosa-associated lymphoid tissue (MALT) lymphoma.

Identify an age-related physiologic change to the stomach

Atrophy of the gastric mucosa

A client has a pyloric obstruction and reports sudden muscle weakness. What action by the nurse takes priority? a. Document the findings in the chart. b. Request an electrocardiogram (ECG). c. Facilitate a serum potassium test. d. Place the client on bedrest.

B ~ Pyloric stenosis can lead to hypokalemia, which is manifested by muscle weakness. The nurse first obtains an ECG because potassium imbalances can lead to cardiac dysrhythmias. A potassium level is also warranted, as is placing the client on bedrest for safety. Documentation should be thorough, but none of these actions takes priority over the ECG.

Describe PEPTIC ULCER DISEASE

Peptic ulcer disease (PUD) results when mucosal defenses become impaired and no longer protect the epithelium from the effects of acid and pepsin.

Describe how/where bile is made, stored and secreted

The liver forms & continually secretes bile, which is essential for the breakdown of fat. The secretion of bile increases in response to gastrin, secretin & cholecystokinin. Bile is secreted into small ducts that empty into the common bile duct & into the duodenum at the sphincter of Oddi. However, if the sphincter is closed, the bile goes to the gallbladder for storage.

Describe the three (3) main functions of the SMALL INTESTINE.

The small intestine has three main functions: movement (mixing and peristalsis), digestion, and absorption. Because the intestinal villi increase the surface area of the small intestine, it is the major organ of absorption of the digestive system.

Identify the different types of ulcers

There are three types of peptic ulcers: 1)gastric ulcers: ulcers that develop inside the stomach. 2)esophageal ulcers: ulcers that develop inside the esophagus. 3)duodenal ulcers: ulcers that develop in the upper section of the small intestines, called the duodenum.

What is the consequence of age-related decrease in liver weight and mass?

This change and an increase in fibrous tissue lead to decreased protein synthesis and changes in liver enzymes. Enzyme activity and cholesterol synthesis are diminished.

Define BRUITS

When auscultating the abdomen, also listen for vascular sounds or bruits ("swooshing" sounds) over the abdominal aorta, the renal arteries, and the iliac arteries. A bruit heard over the aorta usually indicates the presence of an aneurysm. If this sound is heard, do not percuss or palpate the abdomen

What is the consequence of decreased peristalsis and dulled nerve impulses to/from the large intestine?

Decreased sensation to defecate can result in postponement of bowel movements, which leads to constipation and impaction.

What is the significance of elevated CHOLESTEROL lab values?

Increased values indicate possible: Pancreatitis Biliary obstruction

Define GASTRITIS

Gastritis is the inflammation of gastric mucosa (stomach lining). It can be scattered or localized & can be classified according to cause, cellular changes, or distribution of the lesions. Gastritis can be erosive (causing ulcers) or nonerosive. Although the mucosal changes that result from acute gastritis typically heal after several months, this is not true for chronic gastritis.

Identify the priority NANDA-I nursing diagnoses & collaborative problems for patients with peptic ulcer disease (PUD)

1. Acute Pain or Chronic Pain related to gastric and/or duodenal ulceration 2. Upper GI bleeding related to perforation

A client with peptic ulcer disease is in the emergency department and reports the pain has gotten much worse over the last several days.
