1. Which of the following definitions best describes gastritis?
- A. Erosion of the gastric mucosa
- B. Inflammation of a diverticulum
- C. Inflammation of the gastric mucosa
- D. Reflux of stomach acid into the esophagus
Correct answer: C
Rationale: The correct answer is C: 'Inflammation of the gastric mucosa.' Gastritis is characterized by inflammation of the stomach lining, specifically the gastric mucosa. This inflammation can be caused by various factors such as infections, medications, alcohol, or autoimmune diseases. Choice A, 'Erosion of the gastric mucosa,' is incorrect because erosion refers to the wearing away of tissue rather than inflammation. Choice B, 'Inflammation of a diverticulum,' is incorrect because gastritis specifically involves inflammation of the stomach lining, not a diverticulum. Choice D, 'Reflux of stomach acid into the esophagus,' describes gastroesophageal reflux disease (GERD), which is different from gastritis.
2. The hospitalized client with gastroesophageal reflux disease is complaining of chest discomfort that feels like heartburn following a meal. After administering an ordered antacid, the nurse encourages the client to lie in which of the following positions?
- A. Supine with the head of the bed flat
- B. On the stomach with the head flat
- C. On the left side with the head of the bed elevated 30 degrees
- D. On the right side with the head of the bed elevated 30 degrees
Correct answer: C
Rationale: The discomfort of reflux is aggravated by positions that compress the abdomen and the stomach. Lying flat on the back (supine) or on the stomach (prone) after a meal can exacerbate symptoms. Similarly, lying on the right side can worsen reflux. The most appropriate position to alleviate discomfort in a client with gastroesophageal reflux disease is lying on the left side with the head of the bed elevated at a 30-degree angle. This position helps prevent the backflow of stomach contents into the esophagus, providing relief to the client.
3. The nurse is planning to teach the client with gastroesophageal reflux disease about substances that will increase the lower esophageal sphincter pressure. Which of the following items would the nurse include on this list?
- A. Fatty foods
- B. Nonfat milk
- C. Chocolate
- D. Coffee
Correct answer: B
Rationale: Foods that increase the lower esophageal sphincter (LES) pressure will decrease reflux, and lessen the symptoms of gastroesophageal reflux disease (GERD). The food substance that will increase the LES pressure is nonfat milk. The other substances listed decrease the LES pressure, thus increasing reflux symptoms. Aggravating substances include chocolate, coffee, fatty foods and alcohol.
4. Which of the following treatments is used for rectal cancer but not for colon cancer?
- A. Chemotherapy
- B. Colonoscopy
- C. Radiation
- D. Surgical resection
Correct answer: C
Rationale: Radiation therapy is commonly used for rectal cancer to shrink the tumor before surgery, which is not typically done for colon cancer.
5. A nurse is reviewing the results of serum laboratory studies drawn on a client who is suspected of having hepatitis. The nurse interprets that an elevation in which of the following studies is the most specific indicator of the disease?
- A. Erythrocyte sedimentation rate
- B. Serum bilirubin
- C. Hemoglobin
- D. Blood urea nitrogen
Correct answer: C
Rationale: Laboratory indicators of hepatitis include elevated liver enzymes, serum bilirubin level, and erythrocyte sedimentation rate is nonspecific test that indicates the presence of inflammation somewhere in the body. Elevated blood urea nitrogen may indicate renal dysfunction. A hemoglobin level is unrelated to this diagnosis.
