- A. Abdominal computed tomography (CT) scan
- B. Abdominal x-ray
- C. Barium swallow
- D. Colonoscopy with biopsy
Correct answer: D

2. Which of the following diagnostic tests should be performed annually over age 50 to screen for colon cancer?
- A. Abdominal CT scan
- B. Abdominal x-ray
- C. Colonoscopy
- D. Fecal occult blood test

3. 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.
4. Which of the following activities should the nurse encourage the client with a peptic ulcer to avoid?
- A. Chewing gum.
- B. Smoking cigarettes.
- C. Eating chocolate.
- D. Taking acetaminophen (Tylenol).
Correct answer: B
Rationale: Cigarette smoking should be avoided because of its stimulatory effect on gastric secretions. Nicotine also increases the release of epinephrine, which leads to vasoconstriction. The client may chew gum if desired. The client may eat chocolate if desired. A client with a peptic ulcer should check with the physician before taking any over-the-counter drug, but acetaminophen does not typically cause gastric irritation.
5. You have a patient with achalasia (incomplete muscle relaxation of the GI tract, especially sphincter muscles). Which medications do you anticipate to administer?
- A. Isosorbide dinitrate (Isordil)
- B. Digoxin (Lanoxin)
- C. Captopril (Capoten)
- D. Propanolol (Inderal)
Correct answer: A
Rationale: Isosorbide dinitrate (Isordil) is a medication used to relax the muscles of the GI tract in patients with achalasia.
