• A. Increased intrathoracic pressure
• B. Weakness of the esophageal muscle
• C. Increased esophageal muscle pressure

• A. Neutralize acid
• B. Reduce acid secretions

• D. Protect the mucosal barrier

Correct answer: B

Rationale: Medications like ranitidine (Zantac) are H2 receptor antagonists that reduce acid secretions in the stomach, helping to treat peptic ulcer disease.

4. A nurse is providing instructions to a client who will collect a stool specimen for occult blood. The nurse instructs the client to avoid which of the following for 3 days before the collection of the stool specimen?

• A. Milk products
• B. Hard cheese
• C. Turnips
• D. Cottage cheese

Correct answer: C

Rationale: The correct answer is C: Turnips. The nurse would instruct the client to avoid red meat, poultry, fish, turnips, horseradish, and foods such as fruits and vegetables for 3 days before and during testing. These products may alter test results. Choices A, B, and D are incorrect because they are not specifically mentioned as items to avoid before collecting a stool specimen for occult blood.

5. A 30-year-old woman is admitted to the hospital with complaints of severe abdominal cramping and diarrhea. The nurse evaluates the effectiveness of the patient's intravenous therapy. Which of the following laboratory tests BEST reflects hydration status?

• A. Erythrocyte sedimentation rate.
• B. White blood cell count.
• C. Hematocrit.
• D. Serum glucose.

Correct answer: C

Rationale: Hematocrit is the best indicator of hydration status because it reflects the proportion of red blood cells in the blood. An increased hematocrit indicates dehydration, as the blood becomes more concentrated due to fluid loss. Erythrocyte sedimentation rate (Choice A) is a nonspecific marker of inflammation, not hydration status. White blood cell count (Choice B) is an indicator of infection or inflammation. Serum glucose (Choice D) is used to monitor blood sugar levels, not hydration status.
